It was found that about 5% of silane with respect to clay was the optimum dose for the treatment. Around 15% improvement in tensile and tear strength was observed due to silane treatment.
Silane treated organoclay exhibited substantial improvement of the fatigue life, compression set, and rebound property. A detailed study of physical property was carried out. A comparison with low and high structure carbon black filled compound was also carried out. It revealed that the silane treatment helped organoclay to achieve comparable property of the compound having equivalent carbon black loading. Probable mechanism of interaction of silane with clay has also been proposed. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 116:1660-1670, 2010″
“The effect of magnetic anisotropy-axis alignment of individual nanoparticles on the collective aging behavior in the superspin glass state of a frozen ferrofluid has been investigated. ALK inhibitor The ferrofluid studied here consists of maghemite nanoparticles (gamma-Fe2O3, mean diameter=8.6 nm) dispersed
in glycerin at a volume fraction of similar to 15%. The low temperature aging behavior Pifithrin-α Apoptosis inhibitor has been explored through “”zero-field cooled magnetization”" (ZFCM) relaxation measurements using superconducting quantum interference device magnetometry. The ZFCM response functions were found to scale with effective age of the system in both textured and nontextured superspin glass states, but with markedly different scaling exponents, selleck products mu. The value of mu was found to shift from similar to 0.9 in nontextured case to similar to 0.6 in
the textured case, despite the identical cooling protocol used in both experiments. (C) 2010 American Institute of Physics. [doi:10.1063/1.3366615]“
“In this overview we review and model how radiotherapy tumour control and complication rates vary with dose, fractionation, schedule duration, irradiated volume and use of chemotherapy for stage III non-small cell lung cancer (NSCLC), and use the modelling to study the effectiveness of different NSCLC dose-escalation approaches being developed in the UK. Data have been collated for pneumonitis, lung fibrosis, early and late oesophagitis, cord and cardiac complications, and local progression-free survival at 30 months. Dependences of the various end points on treatment-related factors are catalogued and analysed using the linear-quadratic incomplete repair model to account for dose and fractionation effects, making linear corrections for differences in schedule duration, and loosely characterising volume effects using parallel- and series-type concepts. Tolerance limits are calculated for the different end points and distilled into ranges of prescribed dose likely to be tolerable when delivered in 2.5 and 4 week radiation and 6 week chemoirradiation schedules using conformal techniques.
