Fuel cells may power the cars of the future, but it's not enough to just make them work -- they have to be affordable. Cornell researchers have developed a novel way to synthesize a fuel cell electrocatalytic material without breaking the bank.
A Korean research team led by Jung-Hyurk Lim at Chungju National University in Chungju have now introduced a refined nanotip for this technique. With their "nanoquill", it is possible to produce complex nanopatterns from large biomolecules -- such as complete virus particles -- rapidly, precisely, and flexibly.
Panasonic, core partner within imec's Human++ program, and imec today presented at the International Electron Devices Meeting in San Francisco various critical components of a biomedical lab-on-chip sensor enabling fast detection of Single Nucleotide Polymorphisms (SNPs) in DNA, such as a miniaturized pump for on-chip generation of high pressures, a micropillar filter optimized for DNA separation achieving world-record resolution, and a SNP detector allowing on-chip detection using very small sample volumes.
Versatile electronic gadgets should employ a number of important criteria: small in size, quick in operation, inexpensive to fabricate, and deliver high precision output. A new microlaser, developed at the Jozef Stefan Institute in Ljubljana, Slovenia embodies all these qualities. It is small, tunable, cheap, and is essentially the world's first practical three-dimensional laser.
A team of University of California, San Francisco (UCSF) researchers has engineered E. coli with the key molecular circuitry that will enable genetic engineers to program cells to communicate and perform computations.
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.
