+ will effectively reduce the polarization for the electrochemical reactions of the designed LFP@NVP@C composite.关键词:......
phosphor pumped by blue chip with high luminous efficiency, a novel near-infrared phosphor Ce3+/Er3+ doped La3Si6N11 was designed and firstly prepared via conventional solid-state reactions......
efficient reaction regions that correspond to four CJD burners. A higher central oxygen flow improves the mixing between particles and oxygen, thus enhancing reactions and shortening the reaction regions..., the chemical reactions associated with the feed are completed with an acceptable dust rate. Key words: KIVCET furnace; central jet distributor (CJD) burner; computational fluid dynamics (CFD); central......

. A two-step dynamic model of interfacial reaction in SCS-6 SiC/Ti composites was built up, and the rate constant and the activation energy of the interfacial reactions were obtained based... favored by thermodynamics sometimes proceed at such a low rate that they cannot come true in practice. In order to reveal the mechanism of interfacial reactions in SiC/Ti matrix composites......
) Abstract: Based on the thermodynamic analyses of the reactions of ferric oxide(Fe2O3) with sodium carbonate, calcium oxide and calcium silicates, respectively, the thermodynamic of those reactions...
