Researchers have developed a design principle enabling the creation of complex patterns on silicon chips by way of microfabrication.

Thanks to these patterns, vibrations follow predetermined paths.

A material structured in this manner could harvest energy from vibrations or process signals without electricity.

Discovering new catalysts is one of the central challenges in developing clean-energy technologies such as green hydrogen production. Yet catalyst discovery has traditionally remained confined within individual material families, limiting researchers’ ability to transfer knowledge across chemically distinct systems.

Researchers from The University of Osaka created stable cobalt-based honeycomb structures inside a layered material and observed ferromagnetic-like ordering at low temperatures. By introducing a small amount of cobalt into NaSbO₃, the team demonstrated a new platform to study Kitaev materials using abundant 3d transition metals, potentially supporting future cost-effective quantum technologies.
