Researchers have been unable to build an ideal "photonic crystal" to manipulate visible light, impeding the dream of ultrafast optical computers. But now chemists have discovered that nature already ...

Quartz is one of the most abundant minerals and occurs in many different geological settings. However, very few deposits are suitable for HPQ applications. Therefore, HPQ silica sand has become one of ...

We now use quartz-based crystals and their oscillators as standard components in nearly every design. There are countless versions available with different sets of specifications ranging from fairly ...
