This review describes the recent progress in computational catalysis that has addressed C–H bond activation of light alkanes.
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...
sr6nb10o30–nb2o5 nanocomposite was synthesized in 2m naoh aqueous solution. a stoichiometric 1:1 sr:nb molar ratio hydrothermal method at 120°c was used to synthesize this nanocomposite. sr(no3)2 and nb2o5 were used as raw materials. the synthesized nanomaterials were characterized by powder x-ray diffraction (pxrd) technique. it was found that sr6nb10o30 was crystallized in tetragonal crystal ...
