Watching nanowires grow Using X-ray techniques, the University of Siegen and the Karlsruhe Institute of Technology (KIT) have observed the formation of tiny nanowires in gallium arsenide (GaAs) materials in real time. GaAs is used for fiber optics, infrared systems, RF devices in mobile phones and solar panels in spacecraft. Observing the growth of GaAs nanowires could lead to a better unde... » read more

Cryogenic microscopes The European Synchrotron Radiation Facility (ESRF) has developed and commissioned a new cryo-electron microscope. A form of transmission electron microscopy (TEM), cryo-electron microscopy (cryo-EM) is used to study a sample at cryogenic temperatures. A gas is assumed to be cryogenic if it can be liquefied at or below −150 °C. Cyro-EM is often used in structural ... » read more
