Platinum-free catalysts could make cheaper hydrogen fuel cells

The high cost of platinum catalysts used in hydrogen fuel cells limits the commercialization of fuel cell electric vehicles. Scientists are studying alternative catalysts to increase cost-effectiveness and maintain efficiency ...

When predictions of theoretical chemists become reality

Thomas Heine, professor of theoretical chemistry at TU Dresden, together with his team, first predicted a topological 2-D polymer in 2019. Only one year later, an international team led by Italian researchers was able to ...

Why toothpaste and cement harden over time

Take a look inside the cap of your favorite toothpaste, and you might see hard, white residue, a firm version of the smooth paste you squeeze onto your brush.

Study unveils details of how a widely used catalyst splits water

A crystalline compound called ruthenium dioxide is widely used in industrial processes, where it's particularly important for catalyzing a chemical reaction that splits molecules of water and releases oxygen. But the exact ...
