Synthesis and Characterization of a New Aromatic Diamine

Synthesis and Characterization of a New Aromatic Diamine The synthesis and characterization of a new aromatic diamine, 2,5-bis-(aminopyridine-2-yl)-1,3,4-oxadiazole (BAPO), containing pyridine and 1,3,4-oxadiazole moieties has been reported. An organophilic clay has been obtained via cation exchange reaction between the hydrochloride salt of BAPO and sodium montmorillonite (Na+-Mt‎). Basal space and thermal stability of this new modified organoclay were studied by wide-angle X-ray diffraction (XRD) and thermo gravimetric analysis (TGA) techniques. High thermal stability of BAPO-Mt in compared with conventional montmorillonite modified with aliphatic long chain surfactants is shown. A series of organoclay/polyimide nanocomposites (CPN) consisting of BAPO and benzophenone-3,3,4,4-tetracarboxylic dianhydride (BTDA) were also obtained by an in situ polymerization reaction followed by thermal imidization. Structural properties and thermal stability of the obtained CPNs were studied by XRD, TGA, differential scanning calorimetry (DSC), and differential thermal analysis (DTA). The glass transition temperature (Tg) is increased with respect to pristine PI for CPNs 1-3 wt.%. At high clay concentrations, the coagulation of organoclay particles results in a decrease in Tg. Based on the obtained results, CPN 1 wt.% showed the most improved thermal properties. 1. Introduction Polyimides (PI) have gained interests in both academia and industries due to their excellent thermal stability, good resistance toward organic solvents, and improved mechanical properties [1]. They have been have been applied widely in the areas of modern industries [2]. These super engineering plastics have found their way into aerospace, electrical/electronic applications [3], gas separation [4], cell processing, biochip design [5], coating, and composites [6-7]. However, some difficulties come from rigidity and poor solubility in processing of most PIs. Introduction of flexible ether and ester linkages between the aromatic rings of the main chain is an effective way to make these polymers more pliable [8]. In this regard, preparation of poly(ester-amide-imide)s [9], poly(ether amide imide)s [10], poly(amine–amide–imide)s [11] and poly(amide-imide)s [12] have been reported. It was shown that, the incorporation of rigid heterocyclic rings in the main chain of a synthetic polymer could provide excellent thermal and thermo-oxidative stability, which should be useful to decrease negative effects resulting from the introduction of flexible linkages mentioned above. Pyridine nucleolus, as a rigid symmetric aromatic ring, would contribute to the thermal stability, chemical stability, and retention of mechanical property of the resulting polymer at elevated temperature. Furthermore, the polarizability, resulting from the nitrogen atom i n the pyridine ring, could be suitable to improve their solubility in organic solvents [13]. Fujigaya et al. reported among the variety of polybenzimidazole derivatives, the pyridine-containing polymer is known to possess a better mechanical properties and significantly higher proton conductivity due to its higher acid doping ability [14]. On the other hand, it was known that, the thermal stability of polymers can be raised by the incorporation of 1,3,4-oxadiazole moieties into the polymer structure [15]. The outstanding thermal stability is ascribed to the electronic equivalency of the oxadiazole ring to the phenylene ring structure, which has high thermal-resistance [16]. Combination of inorganic materials with organic polymers is one the exciting topics that has been receiving increasing research attention during recent decades. Nanostructured hybrid materials showed wide potential applications in various areas such as in coatings [17], catalysis [18] and biotechnology [19], shape memory polymers [20], and fuel cells [21]. Organically modified sodium clay (Na+-Mt) has improved compatibility, hence higher efficiency of reinforcement, with the polymer matrix. It has been known that, the dispersion of small amounts reinforcing organoclay mineral with high-aspect ratios, such as layered silicate clays, can significantly enhance the properties of PI and its precursor poly(amic acid) (PAA). These improvements can include solvent resistance [22], ionic conductivity [23], enhanced fire retardance [24], increased corrosion protection [25], increased strength and heat resistance [26], decreased gas permeability [27], high moduli [28], and dielectric properties [29]. The enhancements in thermal and mechanical properties of polymer/clay nanocomposites (CPNs) are due to the lamellar structure of montmorillonite those results in high in-plane strength and stiffness, and a high aspect ratio [30-31]. The chemical structure of Na+-Mt consists of two fused silica tetrahedral sheets sandwich an edge-shared octahedral sheet of either aluminum or magnesium hydroxide [32]. The Ca2+ and Na+ ions adsorbed in the interlayer region are exchangeable with organic cations such as long chain alkyl ammonium [33-34]. These organoclays as compatibilizer may be suitable for polymer blends prepared with a low processing temperature. They have low thermal stability and start to decompose around 200 °C, whereas the melt-processing temperatures of most polymers are typically above 200 °C [35]. Furthermore, the preparation and processing of PI/organoclaynanocomposites is carried out at high temperatures, and the thermal decomposition of the long carbon chain of quaternary ammonium salts is inevitable. Thermal decomposition during processing can initiate/catalyze polymer degradation, in addition to a variety of undesirable effects during processing and in the final product [36-37]. To avoid the detrimental effects, modification of clay minerals with imidazolium [38] and phosphonium [39] salts have been noted. As another approach, using of aromatic amines and/or diamines, as swelling agents, has also been considered in the preparation of polyamide and polyimide (PI) nanocomposites [31, 36, 40-41]. Recently, we reported the synthesis of a new aromatic diamine, 2-(5-(3,5-diaminophenyl)-1,3,4-oxadiazole-2-yl)pyridine (POBD). Thermally stable poly(amide-imide)s [12], polyamides [42], polyimides [43], and PI/Clay nanocomposites [44] have been prepared using POBD. We noticed to the metal coordination ability of the 1,3,4-oxadiazole ring adjacent to 2-pyridyl group in designing POBD, Scheme 1. The ability of prepared hybrid materials for removal of the Co(II) ion have also been investigated [41, 45]. Thus, as part of our continuing efforts on the synthesis of polyimides with high thermal stability and metal ions coordination ability, in this work, we wish to report the synthesis and characterization of another designed aromatic monomer containing pyridine and 1,3,4-oxadiazole moieties. In this work, BAPO has been synthesized in four steps starting from 2-amino-6-methyl pyridine (1). The dihydrochloride salt of BAPO was used as a swelling agent for the modification of Na+-Mt. The novel modified organoclay (BAPO-Mt) was used in the preparation of PI/organoclay hybrids of BAPO/BTDA. Thermal stability of BAPO is higher than those for commonly used quaternary alkyl ammonium salts. Therefore, thermal degradation will be prevented during heat treatment needed for curing of poly(amic acid)s. The obtained films were studied by FT-IR spectroscopy, XRD, and SEM. The thermal properties were examined by TGA-DTA and DSC. 3. Results and discussion 3.1. Preparation of BAPO-modified organoclay The new diamine, BAPO 5, was synthesized in four steps. 2-Amino-6-methtypyridine 1 was acetylated with acetic anhydride, oxidized with potassium permanganate, and then alkaline hydrolyzed to give 6-amino-picolinic acid 4 [47]. Cyclo-dehydration to 4 with hydrazine sulfate in the presence of P2O5 in the mixture of POCl3 and concentrated phosphoric acid gave BAPO 5 in overall 20.0% yield (Scheme 2). The chemical structure of BAPO 5 was confirmed by FT-IR, 1H NMR, 13C NMR and mass spectrometry techniques. In the FT-IR spectrum, amino stretching vibrations observed at 3332 and 3202 cm-1. Vibration of C=N bonds of pyridine and oxadiazole rings appeared at 1575 and 1653 cm-1, respectively. The absorption band with medium intensity observed at 1273 cm-1 is related to vibration of C-N bond on the pyridine nucleolus. The amino protons also merged to appear as a broad singlet centered at 6.32 ppm in the 1H NMR spectrum. This peak was disappeared upon addition of D2O and a new peak related to HOD was appeared at 3.90 ppm. In the 13C NMR spectrum of BAPO (5) totally 6 signals observe that it is compatible with the desired structure, Figure 1. Molecular ion peak was observed as base peak in the mass spectra of BAPO, Figure 2. The ‎fragmentation pattern is shown in Scheme 3.‎ To prepare the organophilic clay (BAPO-Mt) via a cation exchange reaction, the Na+-Mt was initially mixed with a hydrochloride solution of the intercalating agent, BAPO 5. Scheme 4 presents a schematic drawing of the modification step. 3.2. Characterization of BAPO-Mt organoclay Figure 3 shows FT-IR spectra of BAPO, sodium montmorillonite, and BAPO-Mt. The spectrum of organoclay exhibits the characteristic bands of Mt and BAPO: N–H stretching at 3330 and 3206 cm-1, –C=N– stretching of the pyridine nucleolus at 1652 cm-1, –C=N– stretching of the oxadiazole ring at 1546 cm-1, stretching vibrations of the double bonds of the aromatic rings in BAPO at 1627 cm-1, and typical bands of montmorillonite at 1033 and 525 cm-1. Figure 4 presents wide XRD of BAPO-Mt and pristine clay. A strong peak is observed at 2à ¯Ã‚ Ã‚ ±Ãƒ ¯Ã¢â€š ¬Ã‚  = 8.95 ° for Na+-Mt, corresponding to the (001) plane, indicating that the interlayer spacing (d001-spacing) of Na+-Mt is about 1.0 nm. The interlayer  ­d001spacing can be calculated from peak positions using Bragg’s law: nÃŽ » = 2d sin ÃŽ ¸, where ÃŽ » is the X-ray wavelength (1.5418 Ã…). The reà ¯Ã‚ ¬Ã¢â‚¬Å¡ection peak of (001) in BAPO-Mt shifted to a lower diffraction angle at 6.90 °, corresponding to the larger d001-spacing (1.28 nm) than Na+-Mt. The replacement of sodium ions with the ammonium ions of BAPO seems to increase the d001-spacing of layered silicate. In general, a larger d001-spacing should assist the intercalation of the polymer chains and should also lead to better clay dispersion within the polymer matrix. Table 1 summarizes the diffraction peaks and the calculated d001-spacings of Na+-Mt and organophilic clays. The thermal treatment of pristine clay under nitrogen consists of two main stages. The first stage occurs from ambient temperature to 200 °C. In this step, free water molecules physically adsorbed on the external surfaces of crystals along with the hydrating water molecules around the exchangeable cation located inside the interlayer space are removed. The second stage is attributed to the dehydroxylation of the structural silanol units of the montmorillonite in the range of 200-700 °C. The temperature intervals of dehydration corresponding to these processes as well as the amount of water released depends on the nature of adsorbed cations and the hydration of the surface [50]. On the other hand, organically modified montmorillonite shows a four-step decomposition process. The vaporization of free water takes place at temperatures below 200 °C, while the surfactant’s decomposition occurs in the temperature range of 200–500 °C. Dehydroxylation of the structural s ilanol groups related to aluminosilicates occurs between 500–800 °C. The last step is the decomposition associated with the combustion reaction between organic carbon and inorganic oxygen [51]. The amount of loaded diamine can be estimated by TGA measurement. Figure 5 shows the TGA curves of the Na+-Mt, the BAPO-Mt, and BAOP. Pristine Na+-Mt contains a large quantity of water due to the intercalation of hydrated sodium (Na+) and hydrated calcium (Ca2+) cations inside the clay layers. These physically adsorbed water molecules are removed in the range from ambient temperature to 230 °C (ca. 3.81% weight loss). The virgin clay also undergoes a 6.36% weight loss within 230-598 °C related to dehydroxylation of the structural silanol units. Whereas, under the same condition BAPO-Mt shows a weight loss of about 10.6% within 230-598 °C related to surface dehydroxylation and thermal decomposition of the surfactant molecules within the organoclay galleries. The difference betwe en weight losses of Na+-Mt and BAOP-Mt within 230-598 °C (Δm = 4.24%) can be attributed to the weight of the loaded diamine. Therefore, the amount of loaded diamines (42.4 mg/g of clay) can be calculated from Eq. (1). Surface energy of Na+-Mt is lowered by the presence of the aromatic ammonium ions within the interlayer spacing. Therefore, the hydrophilic silicate surface transforms to an organophilic one. As seen in Figure 5, the thermal decomposition of the surfactant molecules occurs in two stags at 260 °C and 370 °C. These temperatures are higher than those of decomposition temperature of aliphatic long chain surfactants commonly used for modification of Na+-Mt, which occurs below 200 °C [52]. This study suggests that the BAPO-Mt can be used in the preparation of PI nanocomposites that need to be cured at elevated temperatures. The images obtained by SEM demonstrate significant changes on the surface of the BAPO-Mt. The Na+-Mt particles seem to be stuck together due to moisture (Figure 6a-b), but the organoclay particles are clearly separated in organically modified clay (Figure 6c,d). It seems that the hydrophilicity of the clay is reduced after modification reaction. This study is in accordance with TGA results. 3.4. Polymer Synthesis The present work reports the preparation and characterization of new polyimide CPNs. BAPO-Mt is used as the surfactant at different concentrations. Scheme 5 depicts the synthesis of the PI from the reaction of BAPO and BTDA through thermal dehydration of the poly(amic acid) intermediate. The FT-IR absorptions appearing at approximately 1786, 1727, 1366, 1094 and 722 cm-1 (Figure 7) indicate the presence of imide functional groups in the polyimide film [53]. The polyimide is also characterized by elemental analysis. The observed and calculated values for CHN analyses are in good agreement. Solubility test results (Table 2) show that the obtained PI is soluble in dimethylsulfoxide (DMSO) and concentrated sulfuric acid at room temperature and in other polar aprotic solvents such as, dimethylacetamide (DMAc) and N-methylpyrrolidone (NMP) at boiling temperature of the solvents. For this experiment, about 0.01 g of the polymer sample was examined in 1 ml of solvent at room and at boiling temperature of the solvents. The inherent viscosity of the 0.125 and 0.25 g/dL solutions of the polyimide were 0.36 and 0.39 dL/g, respectively (measured at 25 ± 0.5 °C in DMSO). 3.5. Preparation and characterization of PI/BAPO-Mt CPNs The preparation and characterization of polyimide CPNs with different concentrations of organoclay are also investigated. Scheme 6 shows a procedure for the preparation of PI/BAPO-Mt CPNs by thermal imidization according to method described earlier [44-45]. Figure 8 presents XRD curves of BAPO-Mt, and PI films with various organoclay contents. The lack of any diffraction peak in the XRD patterns of CPNs 1 and 3 wt.%, at 2à ¯Ã‚ Ã‚ ± = 2-10 °, can be attributed to the possible formation of nanocomposites of exfoliated structure. A wide and week diffraction peak at 2à ¯Ã‚ Ã‚ ± = 6.62 ° was displayed by CPN 5%, equaling a d00-spacing of 1.33 nm for the layered silicates in the CPN. The shift to higher interlayer d00spacing with respect to BAPO-Mt (2à ¯Ã‚ Ã‚ ±Ãƒ ¯Ã¢â€š ¬Ã‚  = 6.90 °, d001 = 1.28 nm) is due to the intercalation of the polymer within the organoclay galleries and the formation of an intercalated nanocomposite. Pure polyimide does not show any diffraction peak at 2à ¯Ã‚ Ã‚ ± = 2-10 °. The XRD data are summarized in Table 3. The glass transition temperature of the pure PI is observed at about 271.3 °C (measured by DSC), and the polymer does not show any melting endotherm. The decomposition of the polymer begins at 435.5 °C, and no thermal decomposition occurs below this temperature. To remove any adsorbed water, the polymer samples were heated to 150 °C and then cooled to room temperature prior DSC measurements. Figure 9 shows DSC curves of the PI and CPNs. The results are summarized in Table 4. As seen, the glass transition temperature increases dramatically from 271.3 °C for pure PI to 297.0 °C for CPN 1%. The restriction of the intercalated polymer chains within the clay galleries can be responsible for preventing segmental motions of the polymer chains [46]. However, further addition of organoclay up to 5 wt.% leads to a decrease in Tg. This decrease might be due to the aggregation of BAPO-Mt particles that reduces the interfacial interaction between organoclay and the PI matrix [47]. Both DSC and DTA methods show similar trends of changing in the Tg values upon increasing the organoclay content. Figure 10 shows TGA curves of the pure PI and CPNs. The results are given in Table 4. As seen thermo-gravimetery parameters such as temperature for %10 mass loss and initial thermal decomposition (TD) are increased for CPN 1%, remained almost unchanged in CPN 3%, and then decreased. Char yields are less influenced by the BAPO-Mt content. The drop in the thermal properties at high organoclay loading may be attributed to the better miscibility of polymer and organoclay phases at low organoclay concentrations. Like a superior insulator, the obtained multilayered carbonaceous silicate structure increase the total path of evaporation for small molecules produced during pyrolysis [24]. Based on DSC, DTA and TGA studies, it can conclude that CPN 1% has the most improved thermal properties. The morphology of the PI and CPN film surfaces was also studied be SEM. Some significant and interesting changes have been observed in the surface of CPN 1% with respect to virgin PI film, Figures 11a-d. As seen in the pictures, too many micro-cracks are observed in the background of both films, however, homogeneity of the film surface is increased in the CPN 1wt.%. Conclusion A new thermally stable organoclay has been prepared through the modification of Na+-Mt with BAPO. An X-ray diffraction study confirmed the intercalation of organic surfactant within the silicate layers. SEM images showed that some significant changes occurred on the surface of BAPO-Mt with respect to Na+-Mt, including a decrease in hydrophilicity. Furthermore, the high thermal stability of BAPO avoids pyrolysis during thermal imidization of poly(amic acid) intermediate. The preparation and characterization of new PI/BAPO-Mt CPNs with different contents of organoclay have also been investigated. CPNs 1-5% were prepared from the thermal imidization of a BAPO-Mt dispersion in a poly(amic acid) solution obtained from BAPO and BTDA. XRD patterns showed that exfoliated CPNs may be obtained with the organoclay content of 1-3 wt.%, but at higher clay loadings intercalated structure is significant. TGA-DTA and DSC measurements showed that Tg increases with increasing organoclay content loadin g to 1 wt.%, and then decrease thereafter. SEM images showed that CPNs 1% produces smoother film than that of the virgin polyimide.

Life of Fame

Life of Fame Marilyn Monroe once said, â€Å"Hollywood is a place where they’ll pay you a thousand dollars for a kiss and fifty cents for your soul† (â€Å"Marilyn Monroe†). Marilyn Monroe was an actress, singer, model and showgirl. She is highly regarded as one of the greatest sex symbols of the twentieth century (Lefkowitz 5). â€Å"It's better for the whole world to know you, even as a sex star, than never to be known at all† (â€Å"Marilyn Monroe†). She starred in a number of successful motion pictures during the 1950’s (Krohn 2). People loved Marilyn Monroe because she was a combination of beauty and brains.Although Marilyn Monroe was an influential figure, she lived a life of controversy filled with scandalous affairs and life style choices broadcasted for the world to hear and see. Marilyn Monroe had a very difficult life. She was born into the world on June 1st, 1926. She was born at California’s LA General Hospital. Marilynâ⠂¬â„¢s birth name was Norma Jeane (â€Å"Marilyn Monroe†). Norma Jeane’s parents weren’t always there for her. She never knew her father, and her real mother was not loving. Gladys, Jeane’s mother, put Norma Jeane into a foster home at age six. She was an orphan for awhile.When she was in the foster home, she did not feel loved. She felt like a maid in the house she lived in. Living in the foster homes, she felt like she grew up without someone taking care of her (â€Å"Marilyn Monroe†) At age nine, Norma Jeane was over weight for her age. She felt different and alone. Jeane often dreamed about being beautiful. In her eyes she thought everything would be easier (Krohn 25). Grace, her favorite foster mom, said, â€Å"One day you’ll be a beautiful woman- maybe even a movie star (22). Later on Jeane went to high school. She lived with Grace for 7 years. Norma Jeane loved sports.She tried to get into drama, but she thought it wasn’t her thing. She made many of friends and she grew into her body. It was the first time she felt beautiful. Every time she walked, she got the attention of all the boys (30-35). She realized then she liked the feeling of attention (25). Norma Jeane used her beauty to win love and attention of others (Lefkowitz 25). In 1933 Gladys came and took her away from Grace because she got a steady job at a movie studio (18). They bought a house in Hollywood (19). Their address was 6812 Arbol Drive. After a few months, their grandfather died (19).Gladys went into major depression and was not fit to take care of Jeane. She got put into a ward house, where she would spend the rest of her life (21). Again, Jeane went into a foster home. She thought that marriage was the only was out(41). She married three times, and she got divorced 3 times (43). Norma Jeane realized what she wanted to do in life. She got a job at studios and she decided to go into modeling. She changed her name to Marilyn Monroe. She picked the name Marilyn because she simply liked how it sounded with Monroe. Monroe was her grandmother’s last name (57).Marilyn Monroe had a very successful career that lead to her untimely death. On August 5th, 1962, Marilyn Monroe was found dead in her California home at the age of 36. They ruled out the cause of her death as an overdose, since they found an empty bottle of sleeping pills by her bed. Marilyn Monroe was buried on August seventh (Krohn 113). Over the rainbow played at her funeral. (114). Even today Marilyn Monroe accomplishments in movies are still remembered by many people. Marilyn Monroe had many noteworthy achievements in her life. To begin, she is remembered for her beauty.Marilyn Monroe is still popular today (â€Å"The Lovely Marilyn Monroe†). A person once said about Marilyn Monroe â€Å"She will be making people laugh and cry for generations to come†(Krohn 114). Her major accomplishment is being the biggest and strongest sex symbol in t he world (â€Å"Marilyn Monroe†). Her first movie was in 1946; her first part was an unimportant role as a Telephone Operator in the 1947 film ‘The Shocking Miss Pilgrim (Krohn 116). Her biggest movies were Some of Marilyn Munroe's most famous movies were: Some Like It Hot, Gentlemen Prefer Blondes, Something's Gotta Give, and How To Marry A Millionaire.She made more than 200 million dollars per-movie (â€Å"Marilyn Monroe†). Marilyn Monroe won three Golden Globe Awards: Best Motion Picture Actress in Comedy/Musical for Some Like It Hot (1960), World Film Favorite Female (1953), World Film Favorite Female (1962). She was also nominated for another Golden Globe for: Best Motion Picture Actress in Comedy/Musical Bus Stop (1956)(â€Å"Marilyn Monroe†). She went into modeling. She was in she first issue of â€Å"PlayBoy†. Marilyn Monroe’s most famous picture was â€Å"The Dress†(â€Å"Marilyn Monroe†). Marilyn Monroe is most famous for performance of â€Å"Happy Birthday† to former president, John F.Kennedy. In her remembrance, in 1995, the US Postal Service paid tribute to her honoring her with a thirty-two cent stamp with her picture on it (â€Å"Marilyn Monroe†). In addition to Monroe’s accomplishments, she set standards in the movie and modeling world of Hollywood. Marilyn Monroe made an impact on the world by becoming a role model for some people, despite all the gossip perpetuated by society. Marilyn Monroe overcame a difficult childhood to become of the world's biggest sex symbols and beauty icons (â€Å"Marilyn Monroe†). She encouraged people to believe in themselves (â€Å"The Lovely Marilyn Monroe†) She was a voluptuous model.Today, she would not be a model. She was a size 12 in dresses (â€Å"Marilyn Monroe†). She once said â€Å" I don’t want to make money, I just want to be wonderful† (â€Å"Marilyn Monroe†). She just wanted to inspire people to follow their dreams because she followed her and she ended up where she wanted to be. She showed girls that you can be happy without a man, but like always said â€Å"You can’t live with them, you can’t live without them† (â€Å"The Lovely Marilyn Monroe†). She was a strong girl and did not take no for an answer. When they were looking for a blonde head girl, she dyed her hair.She tried her best to get what she wanted. Some people underestimate her for being a dumb blonde, but her favorite thing to do was read (â€Å"Marilyn Monroe†). She loved challenges and attention. She was the ultimate role model for young women and girls who admired her glamour and image. She knew she was not flawless. She had flaws and she sometimes did show them (â€Å"Marilyn Monroe†). Even though Marilyn Monroe left a positive impression on the world, her actions resulted in negative rumors about her. These rumors was not what people made her out to be. To some people, she was sleazy and a dumb blonde.Since people thought that, they also believe she had twelve abortions before the age of twenty-nine. Some may look down on her because of her appearance in the first issue of Hugh Hefner's Playboy as the first Playmate (â€Å"The Lovely Marilyn Monroe†) She posed naked for Playboy. She was Playboys â€Å"Sweetheart† in December 1953. One of the most scandalous things people still talk about it is her performance to the president. It is known as the National Scandal. She performed for President, John F. Kennedy, on his forty-fifth birthday. On May 19th, 1962, she sang Happy Birthday at Madison Square Garden.It was a Democratic fundraiser. Later that night, a black and white picture was taken of them laughing and talking. The picture is worth fifty thousand dollars, it is the only picture of the together. After that night, some people thought that Marilyn Monroe and JFK had an affair. Later on, things got around that she w as involved with Robert Kennedy, John Kennedy's brother, around the time of her death. Sadly, no one will ever know if any of that was true because two months later Marilyn Monroe died, so did the Kennedy brothers. It has been fifty years and that rumor still goes on (â€Å"Marilyn Monroe†).Rumors are that Marilyn was being monitored by the Kennedy's and the Mafia (â€Å"Marilyn Monroe†). Since these thoughts got around, she was looked down on. She was supposed to be a role model for young girls all over the world. She stood for independence in women. In effect Marilyn Monroe set an inadequate example for young girls by having these affairs. Marilyn Monroe’s death had a devastating and permanent impact on the world; no one saw it coming. She was found dead in her California home. Her death was declared a suicide by an overdose of sleeping pills, but many signs show it was murder, making it impossible for a suicide (Berman 132-133).Marilyn Monroe was a sweet, inn ocent, vibrant young woman who got caught up in the glamour of show business. She took miserable situations and made a brilliant career out of herself. Marilyn Monroe's troubled life and apparent suicide, along with her failed relationships with the very high profile men in her life, aroused sympathy and interest amongst her fans. This helped Marilyn Monroe's career as a legendary figure (â€Å"Marilyn Monroe†) Marilyn Monroe joined The Walk of Fame on February 9, 1960. Her star is placed at 6774 Hollywood Boulevard.Marilyn Monroe left a mark on the world that can never be changed. She set the standards for modeling and acting that no one can ever even attempt to meet (â€Å"The Lovely Marilyn Monroe†). Some of her rumored actions were forgivable, but the Playboy incident smirched her reputation. She was supposed to be a role model for young children, yet she modeled naked for everyone to see. This inappropriate action led her to a lowered self-image, which impacted ne gatively in society; however, she will still live on through her legacy in our hearts.

Bedside Shift Report Essay

Policies and procedures are review, revamp and implement constantly in health care facilities to ensure safe patient care is being deliver. Effective communication is a critical part in providing safe patient care. Usefulness communication is essential during shift report in order to provide safe care and meet goals for the patient. There is a trend where hospitals are bringing shift report to the bedside in order to improve the effectiveness of communication between the nurses. At Kaiser Santa Clara, the facility I currently work at, has a standard policy and procedure regarding the handoff communication during shift change, according to the policy the two nurses are to review information that is standardized to the following: †¢Diagnoses and current condition of the patient †¢Medications given or due †¢Isolation status †¢Recent changes in condition or treatment †¢Anticipated changes in condition for treatment †¢What to watch for in the next interval of care The purpose of the policy is to provide an interactive dialogue that allows for up-to-date information on the patient’s care. The policy is referenced to the Joint Commission-mandated focus on improving patient safety through effective caregiver communication. According to the Joint Commission, as estimated 80% of serious medical errors are attributable to miscommunication between caregivers when transferring responsibly for patients (Wakefield, Ragan, Brandt & Tregnago, 2012). Shift report happens two, three, or more times in a day, but nurses receive little formal training in this vital responsibility. Nurses may be found legally liable for failing to report necessary information during handoffs (Riesenberg, Leitzsch, & Cunningham, 2010). Therefore, it is imperative for a handoff procedure incorporate an effective way to communicate in order to provide safe patient care. Review of the Literature Traditionally, shift report has been performed away from the bedside either at the nurse’s station or outside of the patient’s room where patient  information is exchanged in an informal way varying from nurse-to-nurse. According to Laws and Amato, information provided, and the actual status of the patient were two different stories when the on-coming nurse came into the room to assess the patient after shift report (2010). Shift report often lack care planning and goals for the shift; these issues often leave the nurses with incomplete data to provide patients with the best possible care (Baker, 2010). Numerous studies and articles have been written in how to improve shift report to coincide with the Joint Commission national patient safety goals, there seems to be an array of information on facilities transition to bedside report, as in giving shift report right next to the patient’s bed. At the University of Michigan Hospital and Health Center, a quantitative study was conducted to improve the practice of nursing shift-to-shift report by taking it to the bedside. Over a six month period, a group of nurses were observed during shift change to determine how the implementation of bedside reporting was being received by the nurses and patients. The results collected between the observation and a brief questionnaire filled out by the nurses, showed that there was a decrease in report time from 45 minutes to 29 minutes due to that nurses that did not have the privacy of socializing at the nurses station, which decreases crucial time to give a report on a patient. Nurse satisfaction with report process increased from 37% to 78% when moved to the bedside because nurses could give and receive much more accurate handoff without distractions. An intervention to relocate shift report to the patient bedside resulted in improved satisfaction for nurses and increased direct care ti me to patients (Evans, Grunawalt, McClish, Wood, & Friese, 2012). A critical care quality committee at Regions Hospital in St. Paul, Minnesota, was concerned with an audit that showed 39% of medication errors were found after shift report. This evidence supported the development and strength for bedside report. A qualitative study was conducted by surveying the 69 nurses on two different critical care units. The report’s finding indicated improved communication at the bedside along with allowing the nurses to double check on the intravenous medications that were being  administered to the patient. 84.2% of the nurses felt they were more confident about their report when giving it at the bedside because it gave them an opportunity to provide objective information versus subjected information on the patient (Triplett & Schuveiller, 2011). However, through-out the article there was no information regarding if the 39% of medication errors decrease after the implementation of bedside report. There was a mentioned that 55% surveyed did find errors at the bedside during report; however it was not discussed how these errors were addressed. Overall, bedside report has significantly affected nursing practice in a beneficiary way by nursing staff (Triplett & Schuveiller, 2011). In an effort to improve patient satisfaction, an inpatient nursing unit in a Midwest academic health center made a decision to bring shift report at the bedside. A quantitative was conducted by surveying inpatients and 32 nurses on a step-down unit. A yes or no survey was given to the inpatients regarding the quality of the report that was given at the bedside, and 72% were satisfied with the information that was exchanged between the nurses (Wakefield, Ragan, Brandt & Tregnago, 2012). Following the implementation of bedside report there was a significant increase in patient satisfaction scores. While scores improved, transition to the bedside was not well received by nurses. Data collected showed that nurses were not following the new process of bedside report. 60% of the nurses did not do report at the bedside, however decrease by extensive planning, training and gradual implementation (Wakefield, Ragan, Brandt & Tregnago, 2012). The studies strikingly prove that effective communication at the bedside provides safe patient care that has been well received by patients and nurses in most cases. The research proved that bedside report offered several benefits such as an increase in the following: †¢Nurse-to-nurse accountability †¢Patient satisfaction scores †¢Quality of care ratings †¢Patient safety scores (Wakefield, Ragan, Brandt & Tregnago, 2012). Description of the Process There is a considerable amount of information and studies that support bedside reporting. Bedside reporting has shown to increase patient participation and satisfaction, increase nursing teamwork and accountability, and most importantly improve communication between nurses. Kaiser Permanente prides themselves as being innovated in the health-care industry and keeping patients satisfaction scores high. Based on evidence, Kaiser could continue reach their goals by modifying their shift report policy to incorporate bedside report. In order to modify or implement a new policy, the process seems straight forward with Kaiser; there is a protocol that allows the policy to be handled by the appropriate committee group. For changes in handoff communications, I would have to approach the director of patient safety with my recommendations based on evidence, and then this information is turned over to the nursing policy and procedure committee for review, which then is approved by Chief of Nursing or Services. Why bedside report? Sounds simple, but many nurses are set in their ways and may be resistant to this new technique for number reasons. Let it be known, not only does evidence show that bedside report brings patient safety, it always brings ownership and accountably among the staff. Bedside report allows an opportunity for real-time conversations and transfer of trust of patient care in front of the patient. A clinical nurse leader (CNL) would play in a vital role in seeing the implementation goes smoothly among the nurses. A CNL can help the process by making sure the staff is engaged by providing the appropriate knowledge on how the system is going to be implementing, along with the evidence that supports this new change. The key to successfully implementing bedside report is clearly defining the role of the nurses, standardize what is communicated, and allow for time for the patient’s input. A CNL can follow up on the success of the implementation by rounding on the patients and nurses for feedback and  reporting back to nurses with opportunities or wins, which allows the nurses know how they are doing. In conclusion, it has been provided by evidence based information to show that bedside report is a win-win situation for both the nurses and patients and meets the patient safety goals for Joint Commissions.

Essay on Soulless Technology in William Gibson’s Burning...

Soulless Technology in William Gibson’s Burning Chrome An old adage states that the eyes are the windows to the soul. What if, however, those eyes have a trademark name stamped onto them? William Gibson’s short story Burning Chrome depicts an advanced but soulless society where most of the technological advances are portrayed as being perverted by commercialization and human mechanization, rather than dedicated to improving the quality of life. This paper will touch upon the frivolous consumerism of as well as the dehumanizing uses of technology in the world of Automatic Jack, the reader’s companion throughout the story. Perhaps the most visible example of this perversion is the high degree of commercialized technology in their†¦show more content†¦One of the more popular forms of entertainment is the simstim, a portable simulated stimuli device that allows one to experience the lives of famous people. These people are only famous because they have their lives on display; they are stars that are manufactured by and for the makers of the simstims. Through this device, the user is allowed to experience the world as the star does, complete with parties with the rich and famous and with thrilling hobbies. The eyes, the plastic surgery, the simstims — this technology is not improving the quality of life for humanity; rather it is just another trend, another way to be amused, another way to keep up with fashion’s fickleness. Even medical technology has been misused to keep up appearances. Chrome, a steel-hearted entrepreneur, uses hormones and serums that keep her looking fourteen fo rever. In fact, she had run a drug trade in hormones for years before owning a bar and brothel that also sells hormones that allow the user to relive past memories. Hormones in our society are precious, and are used to treat diabetes, hyperthyroidism and infertility. However, in Jack’s world, they are little more than drugs, used either for escapism or for the maintenance of youthful looks. This trivial treatment of products that could be used for societal improvement further accents the soulless commercialization that is the
