(PhysOrg.com) -- Light has its limitations – in this case not velocity, but rather its diffraction limit, which determines the spatial interaction volume in all implementations of optical spectroscopy and is in general ...
When researchers receive prizes, it is usually to honour their scientific work. However, the photographs from the scanning electron microscope, taken by Siddhartha Pathak during his postdoctoral time at Empa in Thun, Switzerland, ...

(PhysOrg.com) -- By taking advantage of the unique optical properties of nanoscale materials, researchers have designed a lens made of nanowires that can reconfigure its imaging properties without any electronic or mechanical ...
The ever-increasing demand for enhanced performance in electronic devices such as solar cells, sensors and batteries is matched by a need to find ways to make smaller electrical components. Several techniques have been proposed ...
