Ancient sediments that once resided on a lake bed and the ocean floor show sulfur isotope ratios unlike those found in other samples from the same time, calling into question accepted ideas about when ...

Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur ...

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 ...
