Engineers have now achieved a breakthrough with transistors based on gallium oxide (beta-Ga2O3). The newly developed beta-Ga2O3-MOSFETs (metal-oxide-semiconductor field-effect transistor) provide a high breakdown voltage combined with high current conductivity. With a breakdown voltage of 1.8 kilovolts and a record power figure of merit of 155 megawatts per square centimeter, they achieve unique performance figures close to the theoretical material limit of gallium oxide.

Powerful electronic components are indispensable for future communications, for the digital transformation of society and for artificial intelligence applic...

A cancer therapy invented at Rice University has crossed a milestone in clinical trials, a major development in a decades long quest to develop a treatment that destroys tumors without the debilitating side effects of chemotherapy, invasive surgery and radiation.

13 of the first 15 prostate cancer patients treated in a clinical trial of the nanoparticle-based, focal therapy showed no detectable signs of cancer a year after treatment, according to a study published this week in the Proceedings...

A new study shows that graphene sheets can block the signals mosquitoes use to identify a blood meal, potentially enabling a new chemical-free approach to mosquito bite prevention. In a paper published in Proceedings of the National Academy of Sciences, researchers showed that multilayer graphene can provide a two-fold defense against mosquito bites. The ultra-thin yet strong material acts as a barrier that mosquitoes are unable to bite through. At the same time, experiments showed that graphene also blocks chemical signals mosquitoes use to sense that a blood meal is near, blunting their urge to bite in the first place...

Astrophysicists have discovered that the pulsar wind nebula (PWN) surrounding the famous pulsar B0540-69 brightened gradually after the pulsar experienced a sudden spin-down rate transition (SRT)...
