For the composites these properties varied with WF content. An increase in wax content resulted to a decrease in water uptake by the composites, probably because the wax covered the WF particles and penetrated the pores in these

particles. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 118: 1541-1551, 2010″
“The solar-energy absorption material beta-In(2)S(3) was characterized using temperature-dependent photoconductivity (PC) measurements in the temperature range between 30 and 340 K in this study, and thermoreflectance (TR) and photoluminescence (PL) measurements were carried out to identify near-band-edge transitions in the beta-In(2)S(3) tetragonal crystal. The experimental analyses of PL, PC, and TR confirmed that beta-In(2)S(3) is a direct semiconductor with a band gap of 2.073 eV at 30 K and 1.935 eV at 300 K. The PL and PC spectra manifest some defect-related features in the beta-In(2)S(3) single crystal. Vorinostat nmr Two defect emissions and two band-edge luminescences were simultaneously detected in the PL spectrum at 30 K, and the Caspase-3 Inhibitor temperature-dependent PC spectra of beta-In(2)S(3) from 160 to 300 K reveal an additional defectlike or band-to-band feature with an energy located above the conduction band edge (E(C)). The temperature dependences

of the PC transition features in the beta-In(2)S(3) defect crystal were analyzed. The origin and mechanism of all defect states and band-edge transitions in the beta-In(2)S(3) single crystal are evaluated and discussed. (C) 2010 American Institute of Physics. [doi:10.1063/1.3478719]“
“The adjuvant of organic bentonite (OBT), zinc oxide (ZnO), zeolite 4A (4A), aluminum phosphinate (AlPi), terephthaloyl-biscaprolactam (TBC), 2,2′-bis(2-oxazoline) (BOZ), and manganese dioxide (MnO(2)) on flame retardant enhancement of acrylonitrile-butadiene-styrene copolymer (ABS)/polyamide 6 (PA6)/styrene-maleic anhydride (SMA)/ammonium polyphosphate (APP) blends were investigated by using the limiting oxygen index (LOI), the UL-94 (vertical flame) test, thermogravimetric analysis (TGA),

and scanning electron microscopy (SEM). The LOI datas and vertical flame tests showed that the synergistic flame retardant effect of OBT, ZnO, 4A, AlPi, BOZ, and MnO(2) on the ABS/PA6/SMA/APP blend was good, and the LOI value of ABS/PA6/SMA/APP/MnO(2) click here (55/15/5/25/2) system was 33% and class V-0 of UL-94 test was passed. The TGA data demonstrated that the incorporation of adjuvant was known to improve the fire properties essentially accompanied by only minor changes in thermal decomposition. The strong influence of oxygen on the thermal degradation of the ABS/PA6/SMA/APP system, and the oxygen could modify the carbonaceous structure. The microstructures observed by SEM indicated that the adjuvant can promote formation of compact intumescent inorganic-carbonaceous char layers in ABS/PA6/SMA/APP blends. Furthermore, the effects of adjuvant on the mechanical properties of ABS/PA6/SMA/APP blends were also investigated.
