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.
Metal elements and molecules interact in the body but visualizing them together has always been a challenge. Researchers from the RIKEN Center for Life Science Technologies in Japan have developed a new molecular imaging technology that enables them to visualize bio-metals and bio-molecules simultaneously in a live mouse.
By using light, researchers at UC Santa Barbara have manipulated the quantum state of a single atomic-sized defect in diamond - the nitrogen-vacancy center - in a method that not only allows for more unified control than conventional processes, but is more versatile, and opens up the possibility of exploring new solid-state quantum systems.
An interdisciplinary team of researchers has created the first digital cameras with designs that mimic those of ocular systems found in dragonflies, bees, praying mantises and other insects. This class of technology offers exceptionally wide-angle fields of view, with low aberrations, high acuity to motion, and nearly infinite depth of field.
