High-quality cubic GaAs (111)A buffer layers have been grown on an atomically flat c-plane trigonal sapphire substrate having well-defined steps and terraces. A two-step growth method has used where, at early stage, a layer low temperature (LT), followed by second high-temperature layer. In addition to the process, AlAs nucleation multiple annealing employed. The effectiveness of LT in this hig...

conclusions in lighting conditions, most of t-res was isomerized to the other isomer cis-resveratrol. t-res is unstable in alkali ph and when exposed to light. t-res was quite stable at other conditions, and several freeze-thaw cycles did not have any effect on its stability. results our findings revealed that t-res was quite stable in different temperatures ranging from -70 °c to 25 °c, and ac...
