Paul Haney and Mark Stiles of the CNST have developed a theory of current-induced torques that generalizes the relationship between spin transfer torques, total angular momentum current, and mechanical torques, and is applicable to a much wider range of materials than previous theories.
Das Bundesministerium fuer Bildung und Forschung (BMBF) hat rund 13 Millionen Euro fuer insgesamt vier Verbundprojekte im bereich Anwendung von Quantentechnologien in der Informationstechnik zur Verfuegung gestellt.
The White House Office of Science and Technology Policy and the Nanoscale Science, Engineering, and Technology Subcommittee of the National Science and Technology Council request comments from the public regarding the draft National Nanotechnology Initiative (NNI) Strategy for Nanotechnology-Related Environmental, Health, and Safety Research.
The repair of organs, such as human kidney and liver, hinges on the development of three-dimensional (3D) tissue scaffolds with well-defined microstructures. Andrew Wan, Jackie Y. Ying and co-workers at the A*STAR Institute of Bioengineering and Nanotechnology have now developed a photolithography method that can be used to fabricate microstructured 3D tissue materials with high precision.
Scientists have developed a silicon nanowire-based biosensor that can detect the 'reverse transcription polymerase chain reaction' product of dengue type 2 (DEN-2) viruses in less than 30 minutes. The device utilizes silicon nanowires affixed with peptide nucleic acid (PNA) probes to recognize complementary DNA fragments of DEN-2.
Here's the vision: an elderly woman comes into the emergency room after a fall. She has broken her hip. The orthopaedic surgeon doesn't come with metal plates or screws or shiny titanium ball joints. Instead, she pulls out a syringe filled with a new kind of liquid that will solidify in seconds and injects into the break. Over time, new bone tissue will take its place, encouraged by natural growth factors embedded in the synthetic molecules of the material.
Television's favourite Time Lord could not exist without his trusty sonic screwdriver, as it's proved priceless in defeating Daleks and keeping the Tardis in check. Now Doctor Who's famous cure-all gadget could become a reality for DIY-ers across the world, say engineers.
