Instant-Start Computers With New Breakthrough

Instant-Start Computers With New Breakthrough

To encode data, today’s computer memory technology uses electric currents — a major limiting factor for reliability and shrinkability, and the source of significant power consumption. If data could instead be encoded without current — for example, by an electric field applied across an insulator — it would require much less energy, and make things [...]

Scientists Measure Speedy Electrons in Silicon

Scientists Measure Speedy Electrons in Silicon

The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our age.   An international team of physicists and chemists based [...]

Possible Read Head for Quantum Computers

Possible Read Head for Quantum Computers

Nitrogen-vacancy centers in diamonds could be used to construct vital components for quantum computers. But hitherto it has been impossible to read optically written information from such systems electronically. Using a graphene layer, a team of scientists headed by Professor Alexander Holleitner of the Technische Universität München (TUM) has now implemented just such a read [...]

Breakthrough in Flexible Electronics

Breakthrough in Flexible Electronics

A research team led by Prof. Keon Jae Lee of KAIST provides an easier methodology to realize high performance flexible electronics by using the Inorganic-based Laser Lift-off (ILLO), which enables nanoscale processes for high density flexible devices and high temperature processes that were previously difficult to achieve on plastic substrates.   Flexible electronics have been [...]

Gold Nanoparticles Confine Light On Nanoscale

Gold Nanoparticles Confine Light On Nanoscale

A multidisciplinary team at the Centre d’Elaboration de Matériaux et d’Etudes Structurales (CEMES, CNRS), working in collaboration with physicists in Singapore and chemists in Bristol (UK), have shown that crystalline gold nanoparticles aligned and then fused into long chains can be used to confine light energy down to the nanometer scale while allowing its long-range [...]

Ultra-Fast Charging Batteries That Can Be 70% Recharged in Just Two Minutes

Ultra-Fast Charging Batteries That Can Be 70% Recharged in Just Two Minutes

Scientists from Nanyang Technological University (NTU Singapore) have developed a new battery that can be recharged up to 70 per cent in only 2 minutes. The battery will also have a longer lifespan of over 20 years.   Expected to be the next big thing in battery technology, this breakthrough has a wide-ranging impact on [...]

New Records Set for Silicon Quantum Computing

New Records Set for Silicon Quantum Computing

Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers.   The teams created two types of quantum bits, or “qubits” — the building blocks for quantum computers — that each process quantum data with [...]

Circuits That Melt Away When You’re Done

Circuits That Melt Away When You’re Done

Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign. Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, [...]

Prolonged Power in Mobile Devices

Prolonged Power in Mobile Devices

Researchers from The University of Texas at Dallas have created technology that could be the first step toward wearable computers with self-contained power sources or, more immediately, a smartphone that doesn’t die after a few hours of heavy use.   This technology, published online in Nature Communications, taps into the power of a single electron [...]
