A doll in a doll, and then one more, enveloping them from the outside - this is how Thomas Faessler explains his molecule. He packs one atom in a cage within an atom framework. With their large surfaces these structures can serve as highly efficient catalysts.
When William Murphy works with some of the most powerful tools in biology, he thinks about making tools that can fit together. These constructions sound a bit like socket wrenches, which can be assembled to turn a half-inch nut in tight quarters, or to loosen a rusted-tight one-inch bolt using a very persuasive lever. The tools used by Murphy, however, are proteins, which are vastly more flexible than socket wrenches - and roughly 100 million times smaller. One end of his modular tool may connect to bone, while the other end may stimulate the growth of bone, blood vessels or cartilage.
The DARPA Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) program seeks to realize this goal by creating electronic systems inspired by the human brain that can understand, adapt and respond to information in fundamentally different ways than traditional computers.
REACH, the European Union's primary regulation on chemicals is failing to identify or control nanomaterials. That is the conclusion of "Just Out of REACH: How REACH is failing to regulate nanomaterials and how it can be fixed", a new report by the nonprofit Center for International Environmental Law (CIEL).
Researchers in France have developed a way to deposit a thin aluminum RFID tag on to paper that not only reduces the amount of metal needed for the tag, and so the cost, but could open up RFID tagging to many more systems, even allowing a single printed sheet or flyer to be tagged
Tiny metallic nanoparticles that shimmer in the light like the scales on a butterfly's wing are set to become the color-change components of a revolutionary new approach to point-of-care medical diagnostics.
A series of one day regional roadshows will facilitate face-to-face discussions with scientists and researchers who work with the latest tools and techniques in the world of photonics. The first meeting will be held at Imperial College, London on Thursday 26th April.
For the first time, a group of chemists, physicists, and engineers has developed crystalline materials that allow an optical fiber to have integrated, high-speed electronic functions. The potential applications of such optical fibers include improved telecommunications and other hybrid optical and electronic technologies, improved laser technology, and more-accurate remote-sensing devices.
