Glass: Characterizing with precision and efficiency

(Phys.org)—At home, in the car or with industrial processes – glass is a universal material. Its properties are so extraordinary that frequently there are no alternatives to this material. Take, for example, high-temperature ...

High-resolution microscopy without a lens

(Phys.org)—Over the past several years, major advances have been made at UCLA in the field of lens-less computational imaging technology, particularly in the design of lens-free holographic microscopes, which, because of ...

A small-scale solution with a large-scale impact

(Phys.org)—Microchips are per­va­sive in today's high-​​tech society, playing inte­gral roles in the inner work­ings of your cell phone to your Keurig coffee machine.

3-D, after-the-fact focus image sensors invented

(PhysOrg.com) -- At the heart of digital photography is a chip called an image sensor that captures a map of the intensity of the light as it comes through the lens and converts it to an electronic signal.

Sony develops new 'RGBW coding' and 'HDR movie' functions

Sony Corporation today announced the development of two CMOS image sensor models designed for use in smartphones and other devices. They are equipped with Sony's unique “RGBW Coding” function which allows images ...

Vertical silicon nanowires for nonvolatile memory devices

As electronic devices become smaller and more sophisticated, the search for compact nonvolatile memory becomes increasingly important. However, conventional silicon technologies, such as complementary metal-oxide-semiconductor ...

Faster, smaller and more economical gallium nitride transistors

For the first time, researchers from CNRS France and ETH Zurich have succeeded in producing high-performance high-electron-mobility transistors (HEMTs) made of gallium nitride (GaN) on a silicon(110) wafer. This makes these ...
