Tools made of hard materials and ceramics such as tungsten carbide are particularly wear-resistant. However, the tools used ...

Materials scientists can learn a lot about a sample material by shooting lasers at it. With nonlinear optical microscopy—a ...

As stellarator configurations are challenging to build, most fusion experiments today are tokamaks (a short form for a Russian expression that translates as ‘toroidal chamber with magnetic coils’).

Abstract: In this letter, we proposed an ultrasonic sensor-based resolution tunable displacement measurement system by using an extension spring. In the proposed method, a linear extension spring is ...
