Building bricks from plastic waste

Revolutionary 'green' types of bricks and construction materials could be made from recycled PVC, waste plant fibers or sand with the help of a remarkable new kind of rubber polymer discovered by Australian scientists.

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 ...

Understanding the 'fundamental nature' of atomic-scale defects

Materials scientists study metals, polymers, and other substances at the atomic level in order to find new ways to control a material's physical properties, such as how strong or how malleable it is. One key aspect of this ...

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 ...
