A Light-Driven Method for the Direct ‘Uphill’ Isomerization of Many Olefin Classes

Chemists have long sought methods to convert more stable internal olefins into less stable terminal olefins. Isomerization reactions that proceed against a thermodynamic bias, as this one would, are generally challenging for conventional thermal catalysis.

Engineers Develop a New Diamond Transistor with High Hole Mobility

Using a new fabrication technique, NIMS has developed a diamond field-effect transistor (FET) with high hole mobility, which allows reduced conduction loss and higher operational speed. This new FET also exhibits normally-off behavior (i.e., electric current flow through the transistor ceases when no gate voltage is applied, a feature that makes electronic devices safer). These results may facilitate the development of low-loss power conversion and high-speed communications devices.
