Topological insulators could form the basis for revolutionary electronic components. However, as they generally only function ...

Physicists have long known that neutrons are slightly positive at the core and slightly negative at the surface but overall are electrically neutral. However, until recently, they hadn't quantified ...

This study is led by Prof. Hai-Zhou Lu and Prof. Qihang Liu (Shenzhen Institute for Quantum Science and Engineering and Department of Physics, Southern University of Science and Technology). Every ...

Recently, [Solder Hub] put together a brief video that demonstrates the basics of a Hall Effect sensor — in this case, one salvaged from an old CPU fan. Two LEDs, a 100 ohm resistor, and a 3.7 volt ...
