Frustration crops up throughout nature when conflicting constraints on a physical system compete with one another. The way nature resolves these conflicts often leads to exotic phases of matter that are poorly understood. New research explored how to frustrate a quantum magnet comprised of sixteen atomic ions - to date the largest ensemble of qubits to perform a simulation of quantum matter.
Ion channels are important drug targets. A young team of researchers from the Department of Pharmacology and Toxicology, University of Vienna investigated the opening and closing mechanisms of these channels: for the first time the full energy landscape of such a large protein could be calculated in atomic detail.
In a promising development for diabetes treatment, researchers have developed a network of nanoscale particles that can be injected into the body and release insulin when blood-sugar levels rise, maintaining normal blood sugar levels for more than a week in animal-based laboratory tests.
IEEE International Electron Devices Meeting Announces 2013 Call for Papers in all areas of Electron Device Technology; Special Focus Sessions this year for BioMEMS, Analog Devices and Circuits, Advanced Semiconductor Manufacturing, and Terahertz Devices.
Modern applications of glass in such diverse fields as energy, medicine, electronics, photonics, and communications are critically dependent on our awareness and appreciation of the intrinsic connections between glass and nanotechnology. Although glass is seldom if ever mentioned in early texts on nanotechnology, there are numerous examples where the understanding of glass at the nanoscale level has proved transformational in the fabrication and application of this material. As such, glass is a quintessential nanotechnology material.
A new semiconductor device capable of emitting two distinct colours has been created by a group of researchers in the US, potentially opening up the possibility of using light emitting diodes (LEDs) universally for cheap and efficient lighting.
Farewell, expensive single-charge batteries. A new concept becomes proven reality, as MicroGen's nanotechnology-based energy harvester - researched and developed by the company at the Cornell NanoScale Science and Technology Facility - begins commercial-scale production this summer.
If quantum computers are ever to be built, qubits will have to be made more robust and more numerous. New work by scientists at the Joint Quantum Institute addresses both of these concerns - noise reduction and scalability.
Microchips play an important role in industrial and household electronics. Their miniaturized circuits must not only function faultlessly but also consume as little energy as possible. Researchers are now working on making the tiny devices even more efficient.
