Since the development of superconducting electronic devices there has been a need to develop a three terminal transistor like device sensitive enough to measure small voltage and current signals typical of those associated with single electron and photon events.
A group of researchers in the Department of Particle & Nuclear Physics at Oxford University has designed a superconducting device with properties analogous to those of a traditional semiconducting transistor. The Quatratran (Quasiparticle Trapping Transistor) has the ability to amplify small signals and also be utilised as an electronic switch. The Quatratran is sensitive enough to detect, and measure the energy of, single photons and hence has applications in infrared and X-ray astronomy, materials characterisation, and florescence measurements of biological samples.
With security being such an important issue at present, one of the most important potential applications of the technology is that it is capable of detecting nuclear radiation.

Augsburg chemists present a new technology for compressing, storing and transporting highly volatile gases in porous frameworks/New prospects for gas-powered vehicles
Storage of highly volatile gases has always been a major technological challenge, not least for use in the automotive sector, for, for example, methane or...
When we put water in a freezer, water molecules crystallize and form ice. This change from one phase of matter to another is called a phase transition. While this transition, and countless others that occur in nature, typically takes place at the same fixed conditions, such as the freezing point, one can ask how it can be influenced in a controlled way.
We are all familiar with such control of the freezing transition, as it is an essential ingredient in the art of making a sorbet or a slushy. To make a cold...
