Alcohol oxidation is an important reaction in organic syntheses. Some of these reactions must beunder difficult conditions in respect of high temperature and pressure. In many cases, reactions areconducted by environmentally in appropriate solutions. In this study, preparing an effectivenanocatalyst and estimating the optimum provisions of its production processes are assessed. Twomajor and cru...

A full-vectorial finite-element-based approach has been developed to find accurate modal solutions of acoustic modes in Ge-doped planar silica waveguides. The structural symmetry is exploited, and Aitken's extrapolation is also used to improve the accuracy of the solution. The spatial dependences of the dominant and nondominant displacement vectors are shown for the fundamental and higher-order...
