A recently published study led by Virginia Commonwealth University researchers sheds new light on how water interacts with the nanomaterial graphene, a single, thin layer of carbon atoms arranged in a hexagonal honeycomb lattice.

The researchers’ findings could hold implications for a variety of applications, including sensors, fuel cell membranes, water filtration, and graphene-based electrode materials in high-performance supercapacitors.

The study, “Solvent–Solvent Correlations across Graphene: The Effect of Image Charges,” was published in the American Chemica...

Scientists have developed a new way of making fuel cell membranes using nanoscale fasteners, paving the way for lower-cost, higher-efficiency and more easily manufactured fuel cells. The internal workings of fuel cells vary, but basically all types mix hydrogen and oxygen to produce a chemical reaction that delivers usable electricity and exhausts ordinary water as a by-product. One of the most efficient types is the proton exchange membrane (PEM) fuel cell, which operates at low enough temperatures to be used in homes and vehicles.

To generate electricity, PEM fuel cells rely on 2 chemical compartments separated by a permeable catalyst membrane...
