Lithium-sulfur batteries can potentially store five to 10 times more energy than current state-of-the-art lithium-ion batteries at much lower cost. Current lithium-ion batteries use cobalt oxide as ...

A breakthrough strategy using sulfur-rich precursors to engineer porous heterojunctions has overcome critical bottlenecks in water-splitting catalysts, paving the way for green hydrogen production.

The heterogeneous reaction of thiols with lead oxide to form insoluble lead thiolates is the basis for a new process that separates thiols from a hydrocarbon stream. The process uses inexpensive ...

Part 1 of this series of three articles dealt with the uses hydrogen and nitrogen found in oil refineries. Some of these uses have been around for a long time and are well known; others are newer, ...
