PLLs are critical clocking circuits in virtually all digital applications, and reducing their size and improving their performance is a necessary step to enabling the development of next-generation technologies. • Email to a friend • Physicists gain new insights into superconducting processes in nanostructures Superconductors are regarded as promising components for quantum computers, but so far they only function at very low temperatures. Scientists now demonstrated a so-called energy quantization in nanowires of high-temperature superconductors. • Email to a friend • Scientists found a way to treat cancer with iron oxide nanoparticles Scientists non-invasively released antitumor drug from polymer containers modified with iron oxide nanoparticles inside primary cancer cells. • Email to a friend • DNA-like material could bring even smaller transistors A material shaped like a one-dimensional DNA helix might further push the limits on a transistor's size. The material comes from a rare earth element called tellurium. • Email to a friend • A thermometer can be stretched and crumpled by water Researchers have developed a flexible ionic conductor that is water-processable and thermal stable. • Email to a friend • Researchers virtually 'unwind' lithium battery for the first time An international team of researchers has revealed new insights into the workings of a lithium battery by virtually 'unrolling' its coil of electrode layers using an algorithm designed for papyrus scrolls. • Email to a friend • More Recent Articles Silver sawtooth creates valley-coherent light for nanophotonics Magnetic microrobots use capillary forces to coax particles into position The power of going small: Copper oxide sub-nanoparticle catalysts prove most superior Engineers mix and match materials to make new stretchy electronics Portable lab you plug into your phone can diagnose illnesses like coronavirus
