Silicon lasers start to take shape
Devices made from silicon dominate the microelectronics industry, so silicon should be the material of choice for anyone designing new electronic devices that will be integrated with microelectronic c...
Vortices multiply in superfluid helium-II
Now Demosthenes Kivotides, Carlo Barenghi and David Samuels at the University of Newcastle in the UK have discovered another surprising feature of liquid helium. They have predicted that the coupled m...
X-rays reveal some novel optical activity
The so-called optical activity of materials has been studied extensively since then, so it is perhaps surprising that there is anything new to discover. However, José Goulon of the European Synchrotr...
