An 'exceptionally stable' single-atom catalyst

Scientists at Tokyo Institute of Technology (Tokyo Tech) have shown that single platinum atoms trapped in C12A7 crystals act as a stable and effective catalyst for the hydrogenation of nitroarenes, an essential process in ...

The roughening of a platinum electrode

Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer scale mounds to grow. Leiden chemists Leon Jacobse and Mark Koper, together with physicist Marcel ...

Tiny swimming donuts deliver the goods

Bacteria and other swimming microorganisms evolved to thrive in challenging environments, and researchers struggle to mimic their unique abilities for biomedical technologies, but fabrication challenges created a manufacturing ...

New catalyst outshines platinum for producing hydrogen

Hydrogen, the most abundant element in the universe, packs a powerful punch. And because it contains no carbon, it produces only water when used as a fuel. But on Earth, hydrogen most often exists in combination with other ...

Shocking heat waves stabilize single atoms

Single atoms work great as catalysts, but they usually don't stay single for long. Argonne scientists are part of a team that uses high-temperature shock waves to keep them in their place.

Breakthrough in electrocatalysts reported

Recently, the group of Professor Guo Shaojun in College of Engineering at Peking University developed a novel type of sub-nanometer, highly curved PdMo nanosheet—due to its structural analogy with graphene, it was denoted ...
