Electrocatalytic technologies play a vital role in the advancement of hydrogen energy and other renewable green energy sources, with nanocatalysts
Some proton/anion exchange membrane electrolyzers can use high humidity vapor feed to the anode; however, the cathode of all of these electrolyzers must operate in an air-free atmosphere12,13,14,15,16,17,18,19,20, purged by an inert carrier gas such as nitrogen or argon, resulting in ...
Protein content was determined using the Dumas combustion method in a LECO FP-528 Protein/Nitrogen Analyzer (Leco Corporation, St. Joseph, MI, USA). The conversion factor used to calculate protein content was 6.25 for zein, and 5.70 for gluten flour (Esen, 1980, Jones, 1931). The ...
a, Chemical structure of reserpine. b, Inhibitory effects of reserpine on other ten metabolite-sensing membrane receptors in GlosensorTM cAMP assay (n = 3 biological replicates). c, Docked pose of reserpine into the model of the human HCAR1. The receptor is displayed in cartoon representati...
The reaction sintering method utilizes aluminum powder to react with nitrogen gas at high temperatures to produce aluminum nitride ceramics. The advantage of this method is that the process is relatively simple, the cost is low, and it is suitable for large-scale production. By precisely controllin...
