Selective Electrochemical NOx Reduction to N2 for Sustainable Ammonia Energy Systems
Advanced Materials, EarlyView.Selective electrochemical NOx reduction to N2 offers a promising route to mitigate combustion‐derived NOx emissions in ammonia energy systems. This Perspective links *NO‐mediated pathways, the key intermediate role of N2O, and low‐coverage limitations to the origins of limited N2 selectivity, establishing tandem catalysis and microenvironment ...

Purification of Erythropoietin by Ion-Exchange Chromatography.
Experimental Biology and Medicine, 1958 Abstract : A method is given for the purification of erythropoietin from the filtrate of acidified, boiled plasma prepared from phenylhydrazine anemic rabbits utilizing, DEAE-cellulose ion-exchange columns. The active erythropoietic factor thus prepared has been partially characterized and shown to be an acidic glycoprotein of low molecular weight.

Advanced Materials Interfaces, EarlyView.Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...
