Nanofibers dramatically increase catalytic activity for ultra-low-iridium electrolysis
Decreasing the dependence on expensive platinum-group metals like iridium is vital for the expansion of “green” hydrogen production via proton-exchange membrane (PEM) water electrolysis. Efforts to develop lower-iridium catalytic components for electrolysis have typically focused on mixing iridium into a…
Substituting cobalt in high-strength alloys
A team of scientists at Pacific Northwest National Laboratory (PNNL; Richland, Wash.; www.pnnl.gov) recently unveiled a modified version of the “superalloy” Inconel 617, in which cobalt — a component of the alloy that is also a critical material with significant…
Nanofiltration approach recovers aluminum from process waste
The industrial production of aluminum involves electrolysis of alumina (Al2O3) in molten cryolite, a mineral used as a solvent for the aluminum oxide raw material. Over time, the cryolite accumulates impurities, such as sodium, lithium and potassium ions, which degrade…
The industry’s most comprehensive biodegradability assessments — even for large polymers
