Polyaniline/multiwalled carbon nanotube composite films have been fabricated. It is shown that the nanotubes affect free N–H environment and quinoid units along polymer backbone. A 10-fold increase in conductivity observed elemental analysis indicates compete with chloride ion during HCl doping (see Figure).
All 322 patients at a psychiatric clinic for Indochinese refugees were surveyed to determine the presence of posttraumatic stress disorder (PTSD). If PTSD was not diagnosed time initial evaluation, structured reinterview performed. Seventy percent (N = 226) met criteria current diagnosis PTSD, and an additional 5% 15) past diagnosis. The Mein had highest rate (93%) Vietnamese lowest (54%). Of with who enrolled in before March 1988, 46% 87) given only after reinterview. is common among...

The synthesis and characterization of siloxane-containing perfluorocyclobutane (PFCB) aromatic polyethers, a new class fluorosiloxane polymers possessing well-defined linear structure alternating disiloxanyl-p-phenylene (cis/trans)-1,2-disubstituted perfluorocyclobutyl ether linkages with known fluoroolefin end groups, is described. unexpected formation an aryl Grignard reagent from 4-[(trifluorovinyl)oxy]bromobenzene (2) allowed for the high-yield 4-[(trifluorovinyl)oxy]phenyldimethylsilane...
The fabrication of photonic crystal composites composed encapsulated electrostatically stabilized colloidal arrays with tailorable thermomechanical properties is introduced. Composites sub‐ambient T g exhibited reversible mechanochromic characteristics and a 172 nm stop‐band tuning range, could be modulated up to frequencies 200 Hz. Figure shows reflective the at different strain levels (see also inside front cover).
Abstract This article highlights the preparation of perfluorocyclobutyl (PFCB) aryl ether polymers for a multitude commercial technologies that are academic and global interest. In this account, synthesis various trifluorovinyl (TFVE) monomers tailored specific applications is discussed. The PFCB their properties then presented. Topics include photonics, polymer light emitting diodes (PLEDs), proton exchange membranes (PEMs) fuel cells, atomic oxygen (AO) resistant coatings, hybrid...
Ultra low dielectric constant (k = 1.53) materials with self-cleansing properties were synthesized via incorporation of fluorodecyl-polyhedral oligomeric silsesquioxane (FD-POSS) into recently perfluorocyclopentenyl (PFCP) aryl ether polymers. Incorporation fluorine rich, high free volume, and surface energy POSS a semifluorinated PFCP polymer matrix at various weight percentages resulted in dramatic drop constant, as well significant increase hydrophobicity oleophobicity the system. These...
ABSTRACT: This quasi‐experimental study assessed impact of factors associated with classroom implementation health curricula by North Carolina teachers. School representatives selected and implemented one three tobacco prevention — Project SMART, Growing Healthy, or the Teenage Health Teaching Modules in either sixth seventh grades. Prior to implementation, experimental teachers administrators received extensive training. Implementation data were collected through teacher completed...

A series of 19 p-substituted aromatic trifluorovinyl ether compounds were prepared from versatile intermediate p-Br-C(6)H(4)-O-CF=CF(2) and underwent thermal radical mediated cyclodimerization to new difunctional containing the 1,2-disubstituted perfluorocyclobutyl (PFCB) linkage. The synthetic scope demonstrates functional group transformation tolerance fluorovinyl ether, dimers are useful as monomers for traditional step-growth polymerization methods. (19)F NMR spectra confirmed that...
New fluorinated polyhedral oligomeric silsesquioxane (F-POSS) structures possessing a high degree of hydrophobicity have been prepared via facile corner-capping methodology.
Multilayer fullerenes (carbon nano-onions, CNOs) represent a largely unexplored carbon allotrope due to their inherent insolubility. Expectations are that the properties of these nano-onions will be unique and potentially useful, as has been case with nanotubes (CNTs). CNOs show diminished chemical reactivity; however, established thermal diradical formation reactivity bis-o-diynyl arene (BODA) monomers afforded direct functionalization, solution processing, de-functionalization CNOs; first...
The piezoelectric performance of polyvinylidene fluoride (PVDF) is shown to double through the controlled incorporation carbon nanomaterial. Specifically, PVDF composites containing fullerenes (C60) and single-walled nanotubes (SWNT) are fabricated over a range compositions optimized for their Young's modulus, dielectric constant, d31 coefficient. Thermally stimulated current measurements show large increase in internal charge polarization pure PVDF. electromechanical coupling coefficients...
The universal adoption of an agreed nomenclature has never been more important for the description chemical structures in publishing and online searching. International Union Pure Applied Chemistry (IUPAC) Chemical Abstracts Service (CAS) make similar recommendations. main points are shown here with references to original documents.
