A world-first process for recycling aluminum-smelter waste to be piloted in Tasmania

Aluminum smelting operations require molten cryolite, also commonly called bath, to serve as the electrolyte and dissolve alumina. A typical smelter produces excess bath over time, and there are few markets for reuse or recycle of this material, especially as…

Enzyme engineering breaks out of the cell

A new approach to enzyme engineering has overcome many of the operating challenges associated with large-scale bio-based manufacturing processes by designing enzymes that can thrive outside living cells, eliminating complexity and improving reaction yields. eXoZymes’ (Monrovia, Calif.; www.exozymes.com) cell-free enzyme…

Differences of Temperature-control Devices: Heat Exchangers, Coolers and Heaters

Understanding the differences among key temperature-control devices, such as heaters, coolers and heat exchangers, allows users to realize their unique benefits When it comes to temperature control in industrial, commercial and residential settings, three key devices are often considered: heat…

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…
