Control of carbon loss during synthesis of WC powder through ball milling of WO3-C-2Al mixture
WC–Al2O3 composite powder potentially could be synthesized through milling of WO3–C–2Al mixture.
High temperature resulted from reduction ofWO3 by Al, activates the reduction reaction ofWO3 by C and
brings about carbon deficiency...

Pt catalysts on PANI coated WC/C nanocomposites for methanol electro-oxidation and oxygen electro-reduction in DMFC
In the present study a Pt/PANI/WC/C electrocatalyst was developed to increase the methanol electro- oxidation and oxygen electro-reduction activity and stability of commercial Pt/C electrocatalyst. WC/C was coated...
Effect of heat absorbing alumina addition on mechanochemical synthesis of WC–Al2O3 nanocomposites
It has been shown earlier that formation of undesirable W2C phase during mechanochemical synthesis of WC–Al2O3 composites from WO3–Al–C mixture is due to high temperatures caused by the large heat release during the initial aluminothermic reduction...
Mono-bit millimeter-wave channel estimation: Bayesian and adaptive quantization frameworks
–delta modulation (SDM) to
tackle these issues. In both methods, we exploit the sparsity of mmWC channel in the angle domain. To extract the sparsebased
Laplacian density in case that the sparsity level is unknown, we propose a Bayesian algorithm which...
