Memristors come in threes The race is on to produce a commercial memristor, and a duo from ETH Zurich may be providing a bit more push. "Basically, memristors require less energy since they work at lower voltages," explained Jennifer Rupp, professor in the Department of Materials at ETH Zurich. "They can be made much smaller than today's memory modules, and therefore offer much greater de... » read more

Chasing After Quantum Dots
By Mark LaPedus - 21 Sep, 2015 - Comments: 2

In the 1980s, researchers stumbled upon a tiny particle or nanocrystal with unique electrical properties. These mysterious nanocrystals, which are based on semiconductor materials, were later named quantum dots. Quantum dots were curiosity items until 2013, when Sony launched the world’s first LCD TV using these inorganic semiconductor nanocrystals. Basically, when inserted into an LCD TV,... » read more

South Pole neutrinos A group of researchers using an instrument buried deep in the ice at the South Pole have announced a new observation of high-energy neutrinos from beyond our solar system and the galaxy. The IceCube Neutrino Observatory, a cubic-kilometer-sized detector sunk into the ice sheet at the South Pole, allows researchers to see the byproducts of neutrino interactions with the ... » read more

Making quantum robots Quantum dots are inorganic semiconductor nano-crystals. The technology can be used to boost the color gamut in LCD TVs. It can also be used in LEDs and other products. The problem? Quantum dots are expensive to fabricate. With funding from Dow Chemical, the University of Illinois at Urbana-Champaign has developed a new fabrication process. In doing so, researchers a... » read more

Bigger, Brighter TVs
By Mark LaPedus - 24 Jul, 2015 - Comments: 0

The flat panel display (FPD) industry is undergoing a renaissance, with suppliers rolling out a dizzying array of new, high-resolution technologies for mobile devices, computers and TVs. But despite being in the eye of the innovation storm, FPD equipment makers remain cautious—and for good reason. There are a slew of new LCD fabs being built today, mostly in China. This, in turn, is promp... » read more

5 Technologies To Watch
By Mark LaPedus - 23 Jul, 2015 - Comments: 0

The industry is developing a dizzying array of new technologies. In fact, there are more new and innovative technologies than ever before. And the list is countless. At least from my vantage point, I have come up with my own list of the top five technologies to watch in 2015 and beyond. They are listed in alphabetical order. (See below). Obviously, there are more than just five technologi... » read more

Pyramids Are Not Just For Pharaohs
By Michael Watts - 17 Feb, 2013 - Comments: 1

By Mike Watts There were 3 different applications for pyramid patterns this year at Photonics West in San Francisco; improved LED’s, improved absorbers and single quantum dot devices. This not the first time the ancients have come to the rescue of nano-technology, a couple of years ago we had nano-menhirs. Several groups talked about improving LED’s through pyramids. A Samsung team grew... » read more

Thinking Small
By Barry Pangrle - 06 Dec, 2012 - Comments: 0

By Barry Pangrle “But I am not afraid to consider the final question as to whether, ultimately—in the great future—we can arrange the atoms the way we want; the very atoms, all the way down! What would happen if we could arrange the atoms one by one the way we want them (within reason, of course; you can't put them so that they are chemically unstable, for example). — Richard Feynman, ... » read more
