Valves for tiny particles

Newly developed nanovalves allow the flow of individual nanoparticles in liquids to be controlled in tiny channels. This is of interest for lab-on-a-chip applications such as in materials science and biomedicine.

Electrons give resist layer electrical charge

Leiden physicists found a surprising interaction between electrons and a resist layer. The resist appears to charge and discharge due to incoming electrons. Publication in Physical Review Letters.

Electronics and optics on one chip

Electronics and light don't go well together on a standard "CMOS' chip. Researcher Satadal Dutta of the University of Twente now succeeds in introducing a light connection into the heart of a semiconductor chip. In this way, ...

Liquid light switch could enable more powerful electronics

Researchers have built a miniature electro-optical switch which can change the spin—or angular momentum—of a liquid form of light by applying electric fields to a semiconductor device a millionth of a metre in size. Their ...

Method analyzes non-uniform conductors with a magnetic field

From laptops and televisions to smartphones and tablets, semiconductors have made advanced electronics possible. These types of devices are so pervasive, in fact, that Northwestern Engineering's Matthew Grayson says we are ...

Pushing the limits of lensless imaging

Using ultrafast beams of extreme ultraviolet light streaming at a 100,000 times a second, researchers from the Friedrich Schiller University Jena, Germany, have pushed the boundaries of a well-established imaging technique. ...
