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.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
