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

Hybrid crystals for efficient LEDs A team from the University of Toronto combined two promising solar cell materials together for the first time, creating a new platform for LED technology. The team designed a way to embed strongly luminescent nanoparticles called colloidal quantum dots into perovskite. Perovskites are a family of materials that can be easily manufactured from solution, a... » read more

Photo-doping semiconductors Scientists at Michigan State University found that by shooting an ultrafast laser pulse into a semiconducting material, its properties would change as if it had been chemically doped, in a process known as photo-doping. "The material we studied is an unconventional semiconductor made of alternating atomically thin layers of metals and insulators," said Chong-Yu... » read more

Exploring the proton It took 23 years to conduct the experiments, but physicists have finally provided detailed results about the proton. The Deutsches Elektronen-Synchrotron (DESY) organization conducted the experiments within its particle accelerator from 1992 to 2007. The experiments took place in DESY’s Hadron Electron Ring Accelerator (HERA), an electron-proton collider. Then, ove... » read more

Faster lasers for better memory To visualize in four dimensions the changing atomic configurations of materials undergoing phase changes — which happens when data is recorded on DVDs and Blu-ray disks — Caltech researchers have adopted a novel technique called ultrafast electron crystallography (UEC) that uses ultrafast laser pulses that speed up the data recording process. Interestingl... » read more
