New mass spectrometry technology could transform tiny sample analysis
Mass spectrometry is a powerful technique that allows scientists to break down and identify the building blocks of just about anything by measuring the mass of the tiny particles of which something is comprised. It has a major limitation, however—a.....»»
Electrically modulated light antenna points the way to faster computer chips
Today's computers reach their physical limits when it comes to speed. Semiconductor components usually operate at a maximum usable frequency of a few gigahertz—which corresponds to several billion computing operations per second......»»
