Determining refractive index at relativistic speeds

If you studied advanced physics at high school, there's a good chance that you remember Snell's law, which states how a ray of light bends when it crosses a boundary between two media. According to this law, the ratio of ...

Researchers report new solid contact, ion-selective electrodes

A research team led by Prof. Huang Xingjiu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences constructed a highly stable solid contact calcium ion-selective electrode. They used synchrotron ...
