Free electron lasers (FELs) have proven their worth, but next-generation light sources will have to do better than produce ultrabright x-ray pulses 100 or so times a second. What's needed is megahertz rep rate, a million ...

(Phys.org)—Two independent groups of scientists in the U.S. and Germany have reduced magnetic resonance imaging (MRI) down to the nanoscale, which may enable them in the future to non-destructively detect and image small ...
(Phys.org)—Scientists at CSIRO and RMIT University have produced a new two-dimensional material that could revolutionise the electronics market, making "nano" more than just a marketing term.

(Phys.org)—An international team of researchers working in the Netherlands has conducted an experiment that sheds new light on the phenomenon known as Extraordinary Optical Transmission (EOT)—where light is able to shine ...
A laser capable of working in the terahertz range – that of long-wavelength light from the far infrared to 1 millimetre – enables the 'fingerprint' of, say, a drug to be examined better than can be done using chemical ...
