Redefining the Kilogram and the Ampere
September 29, 2011 — New research using graphene presents the most precise measurements of the quantum Hall effect ever made, one of the key steps in the process to redefine two Système Internationale ... > full story -
Like Fish on Waves, Electrons Go Surfing
September 22, 2011 — Physicists have succeeded in taking a decisive step towards the development of more powerful computers. They were able to define two little quantum dots (QDs), occupied with electrons, in a ... > full story -
Rotating Magnetic Moments: Spin Pumping Effect Demonstrated for First Time
September 12, 2011 — Physicists have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behavior of the spin pumping had previously only been predicted theoretically. ... > full story -
Nanoscale Spin Waves Can Replace Microwaves
September 7, 2011 — Scientists have now demonstrated that theories about nanoscale spin waves agree with observations. This opens the way to replacing microwave technology in many applications, such as mobile phones and ... > full story -
Milky Way Galaxy Might Hold Thousands of Ticking 'Time Bombs'
September 6, 2011 — In the Hollywood blockbuster "Speed," a bomb on a bus is rigged to blow up if the bus slows down below 50 miles per hour. The premise -- slow down and you explode -- makes for a great action movie ... > full story -
Manufacturing Method Paves Way for Commercially Viable Quantum Dot-Based LEDs
August 31, 2011 — Researchers may help resolve the public debate over our future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither. Instead, ... > full story -
Communication Via Electron Spin: Scientists Propose New Kind of Information Technology
August 29, 2011 — Is it time for a communications paradigm shift? Scientists calculate that encoding and sending information via electron spin, instead of voltage changes, may mean tiny chips could transmit more ... > full story -
Strain and Spin May Enable Ultra-Low-Energy Computing
August 15, 2011 — A new type of integrated circuit may be so energy efficient that it could run simply by harvesting energy from the ... > full story -
Searching for Spin Liquids: Much-Sought Exotic Quantum State of Matter Can Exist
August 12, 2011 — The world economy is becoming ever more reliant on high tech electronics such as computers featuring fingernail-sized microprocessors crammed with billions of transistors. For progress to continue, ... > full story -
Bilayer Graphene: Another Step Towards Graphene Electronics
August 11, 2011 — The Nobel Prize winning scientists Professor Andre Geim and Professor Kostya Novoselov have taken a huge step forward in studying the wonder material graphene and revealing its exciting electronic ... > full story
