Abstract ( 8 ) PDF (11695KB) ( 2 ) High energy density lithium-oxygen battery (LOB) is currently regraded as a promising candidate for next-generation power system. However, the dendrite and instability issues of Li metal anode lead to its poor cyclic stability and low energy density. In...
Abstract ( 8 ) PDF (2186KB) ( 5 ) Copper (Cu) is a special electrocatalyst for CO2 reduction reaction (CO2RR) to multi-carbon products. Experimentally introducing grain boundaries (GBs) into Cu-based catalysts is an efficient strategy to improve the selectivity of C2+ products. However...
These results suggested that the protein nanoparticles prepared using SPI-PG were a stable and effective hydrophobic polyphenol carrier and could be applied to food-grade components in functional foods and nutritional supplements. select article Investigation on the interaction between 1,3-dimethyl...
