Molecular storage ring makes its debut
The multitude of energy levels found in molecules has so far defeated the use of laser-based techniques, which rely on exciting transitions that can spontaneously radiate and return to the original levels. Many other ingenious methods have been invented to slow, cool or trap molecules. Paramagnetic molecules have been cooled to sub-kelvin temperatures in a […]
Physics and work
The report was commissioned from the Institute for Employment Studies by the physics programme of the Engineering and Physical Sciences Research Council (EPSRC) to examine the views of organizations that employ postgraduate physicists. University physics departments in the UK produce about 800 new physics PhDs every year, about 200 of whom have been funded by […]

Colourful electrons solve puzzle of ferromagnetism
The spins on electrons can be either up or down and, depending on the spin-spin interactions, materials can be ferromagnetic (i.e. all the spins pointing in the same direction) or antiferromagnetic (i.e. neighbouring spins pointing in opposite directions). Lithium nickel oxide, however, is a very unusual material. Although it appears to be ferromagnetic, the spins […]
Organic metal challenges superconductor paradigm
Moreover, the material in question – an organic crystalline solid called lambda-(BETS)2FeCl4 – contains a large concentration of magnetic ions (S Uji et al. 2001 Nature 410 908). The discovery by Shinya Uji of the National Research Institute for Metals in Tsukuba, Japan, and co-workers at the Institute for Molecular Science, the Electrotechnical Laboratory and […]
Electronics turns over a new leaf
Packaging materials that display animated adverts and containers that sound an alarm if their contents go mouldy are just two possibilities that could result from a new area of technology called “paper electronics”. The substitution of paper for semiconductors in electronic components might sound bizarre, but Swedish physicists are currently developing devices that can […]

Surface acoustic waves go under the microscope
Surface acoustic waves are commonly found in the electronic circuitry of everyday appliances, such as mobile phones and televisions, where they are used to filter frequencies. Surface acoustic waves are also employed in transponders to transmit signals that are modulated in amplitude and frequency to remote locations. In one recent advance, Thorsten Hesjedal of Stanford […]
Will a chip every day keep the doctor away?
Silicon can be developed into a biocompatible and biodegradable material that could lead to smaller, smarter and more-interactive implants in the human body
