A better way to control crystal vibrations

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline ...

Why perovskite solar cells are so efficient

Solar cells with efficiencies above 20% and produced at low costs – perovskites make this possible. Now, researchers of Karlsruhe Institute of Technology (KIT) have gained fundamental insight into the function of perovskite ...

Electrogates offer stop-and-go control in microfluidics

Although microfluidics devices have a wide variety of uses, from point-of-care diagnostics to environmental analysis, one major limitation is that they cannot be modified for different uses on the fly, since their flow paths ...

A paperlike LCD—thin, flexible, tough and cheap

Optoelectronic engineers in China and Hong Kong have manufactured a special type of liquid crystal display (LCD) that is paper-thin, flexible, light and tough. With this, a daily newspaper could be uploaded onto a flexible ...

Designing diamonds for medical imaging technologies

Japanese researchers have optimized the design of laboratory-grown, synthetic diamonds. This brings the new technology one step closer to enhancing biosensing applications, such as magnetic brain imaging. The advantages of ...

Researchers develop heat switch for electronics

Researchers at the University of Illinois at Urbana-Champaign have developed a new technology for switching heat flows 'on' or 'off'. The findings were published in the article "Millimeter-scale liquid metal droplet thermal ...
