The thermogravimetric data indicated that the addition of AP decreased the onset decomposition temperatures, the maximum

mass loss rate (MLR), and the maximum-rate decomposition temperature of GF-PA6 and increased the residue chars of the samples. Compared with the neat GF-PA6, the AP-containing GF-PA6 samples had obviously improved flame retardancy: the LOI value increased from 22.5 to 30.1, and the UL-94 rating went from no rating to V-0 (1.6 mm) when the AP content increased from 0 to 25 wt % in GF-PA6. The results of CCT reveal Compound C in vitro that the heat release rate, total heat release, and MLR of the AP-containing GF-PA6 samples were lower than those of GF-PA6. Furthermore, the higher additive amount of AP affected the mechanical properties of GF-PA6, but they remained acceptable. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 119: 2379-2385, 2011″
“An investigation of amorphous, pyrolytic carbon for semiconductor applications is presented. We have deposited conductive carbon films

on thin silicon oxide and aluminum oxide dielectrics and structured them into metal-insulator-silicon (MIS) capacitors in order to evaluate their electrical properties. The results show that the effective oxide thickness is comparable to metal electrodes, indicating that there is no depletion region between the dielectric and the carbon. The carbon electrodes exhibit very low leakage and Fowler-Nordheim tunneling on silicon oxide and Frenkel-Poole tunneling on aluminum oxide at high fields. The electrical parameters determined from GF120918 research buy the results are comparable to those for poly-silicon. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3511750]“
“PURPOSE: JNK-IN-8 supplier To analyze the effect of asphericity of intraocular lenses (IOLs) on vertical coma aberration after implantation of spherical, spherically neutral, and aspheric IOLs.

SETTING: Department of Ophthalmology, St. Thomas’ Hospital, London, United Kingdom.

METHOD: This observational study recruited patients from previous prospective randomized fellow-eye controlled studies comparing aspheric and spherical IOLs

(3 spherical, 1 spherically neutral, and 2 aspheric IOLs). At postoperative follow-up visits, maximum pupil dilation was achieved and aberrometry was performed using an iTrace aberrometer with a pupil scan size of 5.0 mm. Data on Zernike coefficients Z(3,-1) (vertical coma), Z(3, + 1) (horizontal coma), and Z(4,0) (spherical aberration) and on IOL power were extracted.

RESULTS: Two hundred eyes of 100 patients were recruited. Ninety-two eyes had a spherical IOL, 32 eyes had a spherically neutral IOL, and 76 eyes had an aspheric IOL. Vertical coma Z(3,-1) and spherical aberration Z(4,0) values were highest with the spherical IOLs and lowest with the aspheric IOLs (P = .0163 and P<.0001, respectively). There was no difference in horizontal coma aberration between the 3 IOL groups.
