Many experiments have been done to determine the relative strengths of different knots, and these show that the break in a knotted rope almost invariably occurs at the point just outside the 'entrance' to the knot. The influence of knots on the properties of polymers has become of great interest, in part because of their effect on mechanical properties.(More)
Photochemically generated benzyl radicals react with C(60) producing radical and nonradical adducts Rn C(60) (R = C(6)H(5)CH(2)) with n = 1 to at least 15. The radical adducts with n = 3 and 5 are stable above 50 degrees C and have been identified by electron spin resonance (ESR) spectroscopy as the allylic R(3)C(60)(.) (3) and cyclopentadienyl R(5)C(60)(.)(More)
The gas-phase reaction between MoO3-x and H(2)S in a reducing atmosphere at elevated temperatures (800 degrees to 950 degrees C) has been used to synthesize large quantities of an almost pure nested inorganic fullerene (IF) phase of MoS(2). A uniform IF phase with a relatively narrow size distribution was obtained. The synthesis of IFs appears to require,(More)
C(60) and liquid bromine react to form C(60)Br(24), a crystalline compound isolated as a bromine solvate, C(60)Br(24)(Br(2))(x), The x-ray crystal structure defines a new pattern of addition to the carbon skeleton that imparts a rare high symmetry. The parent C(60) framework is recognizable in C(60)Br(24), but sp(3) carbons at sites of bromination distort(More)
Perfluoroalkylated nanospheres have been prepared by reaction of fullerenes with a variety of fluoroalkyl radicals. The latter are generated by thermal or photochemical decomposition of fluoroalkyl iodides or fluorodiacyl peroxides. Up to 16 radicals add to C(60) to afford easily isolable fluoroalkylated derivatives. The monosubstituted radical adducts were(More)
BACKGROUND Professionals working with psychiatric patients very often have negative beliefs and attitudes about their clients. We designed our study to investigate the effectiveness of anti-stigma interventions among university students who are trained to provide special education. OBJECTIVE The objective of our study was to compare sustainability of the(More)
We designed our pilot study to investigate the effectiveness of computer-assisted anti-stigma interventions among medical students. Convenience sample of 51 consecutive students was evaluated before and after using the Anti-Stigma CO-ED system. After studying the computer program the level of stigma in the group significantly decreased (p<0.02). We(More)
Extended Abstract Interest in ultra wideband (UWB) techniques has grown remarkably in recent years, especially in the area of high data rate, short distance telecommunication systems. Immunity to multipath effects and high throughput makes UWB attractive as a substitute for, or in conjunction with, other technologies, such as 802.11 or general packet radio(More)
