Important losses to the ships of the allied troops by the attacks of the German submarines during World War I led researchers to find specific detecting devices as a means of defence. In 1880 Pierre Curie and his brother, discovered the production of ultrasound waves. Langevin, their student, applied this invention to the localisation of boats. At the end of WWI, research and results ended up b...

A current overview of synchrotron radiation (SR) in macromolecular crystallography (MX) instrumentation, methods and applications is presented. Automation has been and remains a central development in the last decade, as have the rise of remote access and of industrial service provision. Results include a high number of Protein Data Bank depositions, with an increasing emphasis on the successfu...

We present transport measurements of ferromagnetically contacted carbon nanotubes. In both singleand multi-walled nanotube devices, a spin valve effect is observed due to spin-polarized transport. In one single-walled nanotube device, the spin-valve effect is suppressed as the influence of Coulomb charging is observed at around 10 K. To help understand the interplay between the Coulomb charging...
