Purification of bovine pancreatic glucagon as a by-product of insulin production

Brazilian Journal of Medical and Biological Research, 1997
A process for purifying bovine pancreatic glucagon as a by-product of insulin production is described. The glucagon-containing supernatant from the alkaline crystallization of insulin was precipitated using ammonium sulfate and isoelectric precipitation.

Gold‐Stabilized Copper Enables Anodic Hydrogen Evolution for Ultralow‐Voltage CO‐to‐Ethylene Electrolysis

Advanced Materials, EarlyView.
Gold‐stabilized copper suppresses hydroxide‐driven deactivation during anodic hydrogen evolution from furfural. Pairing this low‐potential anode with CO‐to‐ethylene electroreduction enables sub‐1 V operation at 400 mA cm−2, high single‐pass CO conversion, and co‐production of ethylene, furoic acid, and a separate hydrogen stream.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.
