Building 'OLEDs' from the ground up for better electronics

From smartphones to TVs and laptops, light emitting diode (LED) displays are ubiquitous. OLEDs (where the O denotes they are organic, or carbon-based) are among the most energy efficient of these devices, but they generally ...

Making flexible electronics with nanowire networks

A smartphone touchscreen is an impressive piece of technology. It displays information and responds to a user's touch. But as many people know, it's easy to break key elements of the transparent, electrically conductive layers ...

High-sensitivity microwave amplifier detects very weak signals

In the coming years, the European Space Agency (ESA) will be launching a series of new weather satellites that will be able to measure important meteorological data, such as precipitation, water vapor or temperature, better ...

New design for longer lasting night-vision cameras

With the amazing ability to survey areas in complete darkness, night-vision cameras have revolutionized the security industry. But the materials and technology embodied in current cameras tend to degrade under temperature ...

More efficient nano-LED opens door to faster microchips

The electronic data connections within and between microchips are increasingly becoming a bottleneck in the exponential growth of data traffic worldwide. Optical connections are the obvious successors but optical data transmission ...

Automatically darkening windows in a wide range of colors

Electrochromic glass darkens automatically when the sun shines and keeps the heat out. Previously it was available only in blue, and switching times were also long. Now, a new process makes it possible to manufacture other ...
