Moving molecules within molecules from PhysOrg.com
Experts in the field of nanoscience have discovered a way of controlling the motion and detecting the forces that move molecules within molecules.

Physicist Claims First Real Demonstration of Cold Fusion from PhysOrg.com
To many people, cold fusion sounds too good to be true. The idea is that, by creating nuclear fusion at room temperature, researchers can generate a nearly unlimited source of power that uses water as fuel and produces almost zero waste. Essentially, cold fusion would make oil obsolete.

Light-driven 'molecular brakes' provide stopping power for nanomachines from PhysOrg.com
Researchers in Taiwan report development of a new type of "molecular brake" that could provide on-demand stopping power for futuristic nanomachines. The brake, thousands of times smaller than the width of a human hair, is powered by light and is the first capable of working at room temperature, the researchers say. Their study is scheduled for the June 5 issue of ACS' Organic Letters.

Engineers demonstrate first room-temperature semiconductor source of coherent Terahertz radiation from PhysOrg.com
Engineers and applied physicists from Harvard University have demonstrated the first room-temperature electrically-pumped semiconductor source of coherent Terahertz (THz) radiation, also known as T-rays. The breakthrough in laser technology, based upon commercially available nanotechnology, has the potential to become a standard Terahertz source to support applications ranging from security screening to chemical sensing.

Rensselaer student invents alternative to silicon chip from PhysOrg.com
Even before Weixiao Huang received his doctorate from Rensselaer Polytechnic Institute, his new transistor captured the attention of some of the biggest American and Japanese automobile companies. The 2008 graduate’s invention could replace one of the most common pieces of technology in the world—the silicon transistor for high-power and high-temperature electronics.

Precise Alignment to Quantum Dots from PhysOrg.com
“Precise lithographic alignment to site-controlled quantum dots is of major importance for numerous nano-photonic, nano-electronic and nano-spintronic devices,” Sven Höfling tells PhysOrg.com.

Quantum computers take step toward practicality with demonstration of new device from PhysOrg.com
Computers based on the powerful properties of quantum mechanics have the potential to revolutionize information technology and security, but for decades they have remained more theoretical than practical, and difficult to scale up. That is changing, however, as demonstrated in a report this week in the journal Science.

Is quantum Internet search on the way? from PhysOrg.com
In classical computing, random access memory (RAM) is needed to make things “work.” But it is subject to a certain level of energy loss. But what if you could create low-energy quantum access memory (QRAM) that would not only work in terms of quantum computing, but that could also be applied to classical computing?

'Nanomechanical Oscillators' Could Lead to New Class of Computers from PhysOrg.com
More than 50 years ago, a graduate student in Japan conceived the “Parametron,” an electrical circuit that could form the basis for digital computers. The concept ultimately fell flat, but recently a pair of scientists gave new life to the idea, and their work could be a first step toward a nanomechanical computer that is based on mechanical rather than electrical operations.

Go Speed Racer! Revving up the world's fastest nanomotors from PhysOrg.com
In a “major step” toward a practical energy source for powering tomorrow’s nanomachines, researchers in Arizona report development of a new generation of sub-microscopic nanomotors that are up to 10 times more powerful than existing motors. Their study is scheduled for the May 27 issue of ACS Nano journal.
