All animals have collagenous tissue, but only echinoderms (for example, sea cucumbers and starfish) have “mutable collagenous tissue” (MCT) that can rapidly change its stiffness on receiving the appropriate neuronal signals. Researchers at Queen Mary University of London and the European Synchrotron Radiation Facility in Grenoble have now studied MCT using synchrotron small-angle X-ray diffraction […]

Brittle nanocrystalline metals can be made ultrastrong and tough by firing them at extremely high speeds onto a hard target, according to new experiments on silver microcubes by researchers at Rice University and the University of Massachusetts at Amherst. The impact produces an extreme gradient-nano-grained (GNG) structure in the microcubes that has a grain size […]

“Movies” of electrons as they move across a semiconductor junction have been made by researchers at the Okinawa Institute of Science and Technology in Japan using a new imaging technique. Combining photoemission electron microscopy with femtosecond laser pump-probe methods, the technique tracks the motion of electrons on timescales shorter than 1 ps. The researchers say it […]

Researchers at Stanford University in the US and the University of Oxford in the UK have developed a new perovskite that can harvest infrared photons very well. When used together with another perovskite semiconductor that can harvest visible photons, the tandem device can covert solar energy into electricity with 20% efficiency. This figure could be […]

Researchers at the University of Minnesota in Minneapolis have invented a new ultralow power technique to trap nanoparticles in the sub-10 nm gaps between two gold electrodes. The technique, which overcomes many of the problems encountered in traditional dielectrophoresis experiments, could help make portable biosensors….. http://nanotechweb.org/cws/article/tech/66547 Making nanogap electrodes
