A reusable catalyst for the synthesis of esters

A chemist from RUDN University has developed a tin silicate catalyst for the production of estersā€”flavourings, plasticisers, and biofuel components. Unlike existing catalysts, the new material can be made active again and ...

The enigma of bronze age tin

The origin of the tin used in the Bronze Age has long been one of the greatest enigmas in archaeological research. Now researchers from Heidelberg University and the Curt Engelhorn Centre for Archaeometry in Mannheim have ...

Nanowire arrays could improve solar cells

Transparent electrodes are a critical component of solar cells and electronic displays. To collect electricity in a solar cell or inject electricity for a display, you need a conductive contact, like a metal, but you also ...

Alternative material for superconducting radio-frequency cavity

In modern synchrotron sources and free-electron lasers, superconducting radio-frequency cavity resonators are able to supply electron bunches with extremely high energy. These resonators are currently constructed of pure ...

Researchers improve semiconductor laser on silicon

Electrical engineering researchers have boosted the operating temperature of a promising new semiconductor laser on silicon substrate, moving it one step closer to possible commercial application.

Smart liquid goes dark in the heat

A smart liquid that darkens dramatically in response to rising temperature has been developed by researchers at A*STAR. The nanowire-based thermochromic liquid's tunable color-changing behavior was retained even after hundreds ...
