Graphene photodetector integrated into computer chip
The novel material graphene and its technological applications are studied at the Vienna University of Technology. Now scientists have succeeded in combining graphene light detectors with semiconductor chips. Today, most information is transmitted by light – for example in optical fibres. Computer chips, however, work electronically. Somewhere between the optical data highway and the electronic […]
Superconductivity to meet humanity’s greatest challenges
The stage is now set for superconductivity to branch out and meet some of the biggest challenges facing humanity today. This is according to a topical review `Superconductivity and the environment: a Roadmap’, published today, 16 September, in IOP Publishing’s journal Superconductor Science and Technology, which explains how superconducting technologies can move out of laboratories […]
New magnetic semiconductor material holds promise for spintronics
Researchers at North Carolina State University have created a new compound that can be integrated into silicon chips and is a dilute magnetic semiconductor – meaning that it could be used to make “spintronic” devices, which rely on magnetic force to operate, rather than electrical currents. The researchers synthesized the new compound, strontium tin oxide […]
Researchers read the coffee grounds and find a promising energy resource for the future
What’s usually considered old garbage might be a promising asset for our energy supply, according to University of Cincinnati researchers. For many of us, it’s the fuel that wakes us up and gets us started on our day. Now, University of Cincinnati researchers are discovering that an ingredient in our old coffee grounds might someday […]
Tool created to avert future energy crisis
Measurement tool created by UC Riverside assistant professor also helps better prepare the electricity market for the smart grid RIVERSIDE, Calif.— A University of California, Riverside assistant professor of electrical engineering and several colleagues have created a new measurement tool that could help avoid an energy crisis like the one California endured during the early […]
New kind of ultraviolet LED could lead to portable, low-cost devices
Light shines bright at precise frequencies that suit commercial applications COLUMBUS, Ohio—Commercial uses for ultraviolet (UV) light are growing, and now a new kind of LED under development at The Ohio State University could lead to more portable and low-cost uses of the technology. The patent-pending LED creates a more precise wavelength of UV light […]
Penn scientists demonstrate new method for harvesting energy from light
Researchers from the University of Pennsylvania have demonstrated a new mechanism for extracting energy from light, a finding that could improve technologies for generating electricity from solar energy and lead to more efficient optoelectronic devices used in communications. Dawn Bonnell, Penn’s vice provost for research and Trustee Professor of Materials Science and Engineering in the […]
Stanford scientists calculate the energy required to store wind and solar power on the grid
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution, but a new study from Stanford University suggests that might not always be the […]
