High thermal stability of the silicones allows the study of the hydrogen bonding (H-bonding) phenomena of these models within a broad temperature range. (C) 2010 Wiley Periodicals, Inc. J Appl Polym Sci 117: 982-995, 2010″
“We analyze the stress distribution in the nonuniformly bent GaN epilayers grown on a sapphire substrate. By using theoretical analysis combined with an analytical formula describing the realistic shape for the wafer bending of GaN epiwafers, we examine the

effect of nonuniformity in the wafer bending on the stress-value variation over the entire wafer. We show that the stress on the GaN thin film can deviate by similar to 1 MPa from the value obtained by the simple Stoney’s formula that is typically used for the uniformly bent wafer. MX69 research buy We

also show that the maximum value of the stress linearly increases with the bow difference along the horizontal and vertical directions. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3436586]“
“Rod-like or needle-like particles of polyanilinium p-toluene sulfonate have been used as templates for the LY3023414 mouse formation of silica microcapsules or microtubes. Thus, an alkaline aqueous suspension of the needles was treated with tetraethyl orthosilicate to form silica-coated needles, which were subsequently calcined to remove the polyanilinium templates. The rod-like or needle-like polyaniline particles, their silica-coated derivatives and silica microcapsules or microtubes have been characterized by thermogravimetric analysis, Fourier transformation infrared spectroscopy, scanning electron microscopy (SEM), field emission scanning electron microscopy (FE-SEM), and transmission electron microscopy.

“The pressure-volume-temperature (P-V-T) equation of state (EOS) of MgO is widely used as a pressure scale in static compression experiments. However, there are remarkable inconsistencies among different previously proposed MgO pressure scales. We calculated the P-V-T EOS of MgO up to 300 GPa and 3000 K based on experimental Proton Pump inhibitor shock Hugoniot data and a simple thermal pressure model within the Mie-Gruneisen-type analysis framework. All of the parameters used can be measured experimentally with high accuracies. We found that, in overall, the calculated P-V-T EOS of MgO has excellent agreement with the available volume compression data over a wide range of pressure and temperature. A comparison of our results with the previous theoretical investigations has also been performed and confirms that our calculated P-V-T EOS of MgO can be used as a reliable pressure scale for static experiments at high pressures and high temperatures.
