How to design silicon-based quantum wires with figure of merit ($ZT$) larger than three is under hot pursuit due the advantage low cost and availability matured fabrication technique. Quantum consisting finite dimensional dot (QD) arrays coupled electrodes are proposed realize high efficient thermoelectric devices optimized power factors. The transmission coefficient 3D QD can exhibit 3D, 2D, 1...
Conductive transparent ZnS/M/ZnS, (M = Au, Ag, Cu, Al) nano-structures have been simulated by optimization layers thickness, and gold, silver, copper, and aluminum materials were used as a metal layer and zinc sulfide for dielectric layers. Then the optimum simulated structure has been fabricated on a glass substrate by thermal evaporation. The crystallinity properties of the structures, such a...
Background and aim:This study was conducted with the aim of determining the effect of different disinfection methods on the efficiency,pressure drop and quality of medical masks used by medical staff. Also,the filtration efficiency of medical masks was investigated in the present study Materials and methods:In the present study, 4 models of medical masks used by the treatment staff were sele...
