Drexel University's Yury Gogotsi and colleagues recently needed an atom's-eye view of a promising supercapacitor material to sort out experimental results that were exciting but appeared illogical. The team discovered you can increase the energy stored in a carbon supercapacitor dramatically by shrinking pores in the material to a seemingly impossible size - seemingly impossible because the pores were smaller than the solvent-covered electric charge-carriers that were supposed to fit within them.
The world's first three-dimensional plasmon rulers, capable of measuring nanometer-scale spatial changes in macromolecular systems, could provide scientists with unprecedented details on such critical dynamic events in biology as the interaction of DNA with enzymes, the folding of proteins, the motion of peptides or the vibrations of cell membranes.
Uppsala researcher Zhigang Wu, working with collaborators, has devised a wireless sensor that can stand to be stretched. For example, the sensor can measure intensive body movements and wirelessly send information directly to a computer.
RUSNANO, the Korean Ministry of Knowledge Economy's Korea Institute for the Advancement of Technology (KIAT), Singapore Economic Development Board (EDB), the St. Petersburg Government, 360ip and Samho Green Investment Venture Capital (SGIVC) announced today the formation of the Asia Nanotechnology Fund.
Imec and K.U.Leuven have developed a simple double-bead sandwich assay, using both gold and magnetic nanoparticles, for the detection of proteins in serum. The effectiveness of the method was demonstrated by the detection of prostate specific antigen (PSA), which is a marker for prostate cancer.
Imec researchers have developed a methodology to quantitatively map the distribution of active dopants in confined 3D-volumes. This is an important step towards in-depth understanding of transistors based on semiconductor nanowires. The new methodology is based on high-vacuum scanning spreading resistance microscopy (HV-SSRM).
To make solar energy generation cost-effective, the PV industry has to reduce its manufacturing costs well below 1 euro/Wp. This holds for all PV technologies. To reach that ambitious goal, the crystalline Si based PV industry will have to increase the solar cell's efficiency while at the same time reducing the amount of high-purity Si that is used.
Imec and Holst Centre are working on a number of gas sensing technologies, relentlessly scaling the sensor, readout electronics and power consumption. The result will be sensors-on-a-chip, used as standalone e-nose (electronic nose), or as nodes in low-power, wireless sensor networks.
