Water management is crucial for reliable operation of Polymer Electrolyte Membrane Fuel Cells (PEMFC). Here, the gas diffusion layer (GDL) plays an essential role as it has to ensure efficient water removal from and oxygen transport catalyst layer. In this study through porous carbon felt GDLs was simulated using a 3D Color-Gradient Lattice Boltzmann model. Simulations were carried out on micro...
We have analyzed 7,137 samples from 125 different caste, tribal and religious groups of India and 99 samples from three populations of Nepal for the length variation in the COII/tRNA(Lys) region of mtDNA. Samples showing length variation were subjected to detailed phylogenetic analysis based on HVS-I and informative coding region sequence variation. The overall frequencies of the 9-bp deletion ...
This work investigated the effect of friction stir welding (FSW) tool rotation rate and speed on grain structure evolution in nugget zone through thickness 10 mm thick AA5083/AA5754 weldments. Three joints were produced at different combinations FSW parameters. The texture using electron backscattering diffraction (EBSD). In addition, both hardness tensile properties investigated. It was found ...
An atom-efficient, eco-friendly, solvent-free, high yielding, multicomponent green strategy to synthesize triazolo[1,2-a]indazole-triones derivatives by the one-pot condensation of aldehyde, dimedone, and phenyl urazole under microwave Irradiationis presented. Reactions catalyzed by A novel nanomagnetic organic-inorganic hybrid catalyst (Fe@Si-Gu-Prs) was prepared by the chemical anchoring of P...
