Tiniest modified opals ready to manipulate light flow as photonic crystals Nanotechnology / Physics November 29, 2006 \| User rating: 4.1 / 5 after 47 vote(s) \| No comments yet One of the most rapidly advancing areas of applied nanotechnology involves photonic crystals. With their ability to control light propagation, photonic crystals are predicted to replace other methods for devices ...

New theory explains enhanced superconductivity in nanowires Nanotechnology / Physics October 18, 2006 \| User rating: 4.4 / 5 after 42 vote(s) \| No comments yet Superconducting wires are used in magnetic resonance imaging machines, high-speed magnetic-levitation trains, and in sensitive devices that detect variations in the magnetic field of a brain. Eventually, ultra-narrow superconducting ...

Nanocrystals Are Hot Nanotechnology / Physics October 09, 2006 \| User rating: 4.3 / 5 after 34 vote(s) \| No comments yet Scientists at the Department of Energy's Lawrence Berkeley National Laboratory have discovered that nanocrystals of germanium embedded in silica glass don't melt until the temperature rises almost 200 degrees ...

Intel, UCSB Develop World's First Hybrid Silicon Laser Nanotechnology / Physics September 18, 2006 \| User rating: 3.5 / 5 after 85 vote(s) \| No comments yet Researchers from Intel and the University of California, Santa Barbara (UCSB) have built the world’s first electrically powered Hybrid Silicon Laser using standard silicon manufacturing processes. This breakthrough ...

Ferns provide model for tiny motors powered by evaporation Nanotechnology / Physics September 14, 2006 \| User rating: 4.3 / 5 after 56 vote(s) \| No comments yet Scientists looked to ferns to create a novel energy scavenging device that uses the power of evaporation to move itself -- materials that could provide a method for powering micro and nano devices with just ...

New 'superlens' reveals hidden nanostructures Nanotechnology / Physics September 14, 2006 \| User rating: 4.3 / 5 after 40 vote(s) \| No comments yet A microscope used to scan nanostructures can be dramatically enhanced by using a 'superlens,' reports an international team of scientists from the Max Planck Institute (MPI) for Biochemistry and The University of Texas at ...

Physicists invent 'QuIET' - single molecule transistors Nanotechnology / Physics August 30, 2006 \| User rating: 4.1 / 5 after 135 vote(s) \| No comments yet University of Arizona physicists have discovered how to turn single molecules into working transistors. It's a breakthrough needed to make the next-generation of remarkably tiny, powerful computers that nanotechnologists ...

IBM researchers look beyond silicon technology Nanotechnology / Physics August 03, 2006 \| User rating: 3.9 / 5 after 38 vote(s) \| No comments yet Scientists at the IBM Zurich Research Laboratory have demonstrated how a single molecule can be switched between two distinct conductive states, which allows it to store data.

Researchers solve mystery of attractive surfaces Nanotechnology / Physics August 02, 2006 \| User rating: 4.3 / 5 after 29 vote(s) \| No comments yet When smooth surfaces that hate water approach each other underwater, scientists have observed that they snap into contact. This is apparently due to attractive forces that extend for tens to hundreds of nanometers.

Scientists image 'magnetic semiconductors' on the nanoscale Nanotechnology / Physics July 27, 2006 \| User rating: 4.3 / 5 after 22 vote(s) \| No comments yet In a first-of-its-kind achievement, scientists at the University of Iowa, the University of Illinois at Urbana-Champaign and Princeton University have directly imaged the magnetic interactions between two magnetic ...

Ordering by Motion Nanotechnology / Physics July 24, 2006 \| User rating: 4.3 / 5 after 12 vote(s) \| No comments yet The molecules within the living cell sustain a high degree of spatial order even though they are constantly in motion. This seems to defy basic physical principles which stress the strong interplay between ...

Electromechanical imaging in liquid environments: a pathway toward molecular-level resolution of biological systems Nanotechnology / Physics July 01, 2006 \| User rating: 4.2 / 5 after 48 vote(s) \| No comments yet Scientists have demonstrated that electromechanical imaging techniques, when operated in a liquid environment, can provide a resolution of up to 10 times that of the resolution when imaging in air. The liquid ...

Nanocrystals' 'self-purification' mechanisms explained by energetics Nanotechnology / Physics June 21, 2006 \| User rating: 4.4 / 5 after 54 vote(s) \| No comments yet Doping semiconductor nanocrystals will likely provide a basis for a wide variety of nano applications. But since the tiny nanocrystals tend to repel impurities, scientists must first find a way to overcome ...

Shuttling Electrons Nanotechnology / Physics June 05, 2006 \| User rating: 4.3 / 5 after 26 vote(s) \| No comments yet “We are trying to understand quantum nano-electro-mechanical systems,” Jason Twamley explains to PhysOrg.com. “These systems display richer dynamics and interactions than one can obtain with quantum optical ...

New Tools for a Nanotechnology Workshop Nanotechnology / Physics May 25, 2006 \| User rating: 4.3 / 5 after 48 vote(s) \| No comments yet Until recently, nanoscale devices could only be crafted through chemical reactions or by pushing components together on a smooth surface. Researchers at the Technical University of Denmark have developed and ...
