One of the joys of writing up the entries for the 2025 Component Abuse Challenge has come in finding all the different alternative uses for the humble transistor. This building block of all modern ...

Infrared sensors, which act as the "seeing" component in devices such as LiDAR for autonomous vehicles, 3D face recognition systems in smartphones, and wearable health care devices, are regarded as ...

Ice cream comes in many different flavors. But even pure ice, which consists only of water molecules, has been discovered to exist in more than 20 different solid forms or phases that differ in the ...

A team of researchers from the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, has developed a sensor that can identify sodium nitrite (NaNO 2) in various beverages, ...

International researchers have just discovered a new ice form called ice XXI, which compresses water to extreme pressures while keeping it at room temperature. The achievement was accomplished at the ...

A strange new phase of ice has been discovered during experiments with the world's largest X-ray laser. Meet ice XXI, a bizarre phase that forms at room temperature, under extreme pressure. Ice XXI is ...

Abstract: Anti-Stokes fluorescence is emerging as an important new technique to eliminate the internal heat generated in rare-earth-doped fiber lasers and amplifiers. The efficiency of cooling is ...

The UK is pressing ahead with cutting-edge defense projects, the latest including research to protect satellites from laser attack and a technology demonstrator for a jet-powered drone to operate from ...

Abstract: The embedded high-resolution random fiber laser acoustic emission (RFL-AE) sensor for in situ monitoring of buoyancy material is demonstrated. Our proposed embedded RFL-AE sensor can ...
