ELECTRONICS AND ITS GROWTH. Squeezing light into a tiny channel brings optical computing a step closer These are nanofocusing and optical mode properties of the organic hybrid gap plasmon waveguide on the silicon platform used for degenerate four-wave mixing. The insets depict the scaled electromagnetic mode distributions for a wide metal gap of 500 nm and a narrow metal gap of 25 nm, along with the chemical formula for MEH-PPV. By forcing light to go through a smaller gap than ever before, researchers have paved the way for computers based on light instead of electronics. Light is desirable for use in computing because it can carry a higher density of information and is much faster and more efficient than conventional electronics. However, light does not easily interact with itself, so while it can be used to move information quickly, it is not very good at processing information. For example, light is currently used to transfer information over long distances, s

At multilayer, the properties change and the material doesn't emit light. (b) Varying the thickness of each layer results in a thin film speckled with randomly occurring regions that alternately emit or block light. (c) Upon exposure to light, this pattern can be translated into a one-of-a-kind authentication key that could secure hardware components at minimal cost.

------------------------------------------------ Breakthrough could launch organic electronics beyond cell phone screens A discovery by an international team of researchers from Princeton University, the Georgia Institute of Technology and Humboldt University in Berlin points the way to more widespread use of an advanced technology generally known as organic electronics. The research, published Nov. 13 in the journal Nature Materials , focuses on organic semiconductors, a class of materials prized for their applications in emerging technologies such as flexible electronics, solar energy conversion, and high-quality color displays for smartphones and televisions. In the short term, the advance should particularly help with organic light-emitting diodes that operate at high energy to emit colors such as green and blue. "Organic semiconductors are ideal materials for the fabrication of mechanically flexible devices with energy-saving low temperature processes

------------------------------------------------ New way to write magnetic info could pave the way for hardware neural networks Researchers have shown how to write any magnetic pattern desired onto nanowires, which could help computers mimic how the brain processes information. Much current computer hardware, such as hard drives, use magnetic memory devices. These rely on magnetic states -- the direction microscopic magnets are pointing -- to encode and read information. Exotic magnetic states -- such as a point where three south poles meet -- represent complex systems. These may act in a similar way to many complex systems found in nature, such as the way our brains process information. Computing systems that are designed to process information in similar ways to our brains are known as 'neural networks'. There are already powerful software-based neural networks -- for example one recently beat the human champion at the game 'Go' -- but their ef

------------------------------------------------ Nano-watch has steady hands Summary: A new nanomechanical hand shows the time of an electronic clock, by spinning a tiny cylinder using light. A silicon nanorod, less than a thousandth of a millimetre long, can be trapped in thin air using focused laser beams, and spun to follow the ticking of a clock, losing only one-millionth of a second over four days.  Very regular clocks are essential in our everyday lives. They enable us to navigate, from the marine chronometers used to determine longitude, to GPS. Stable clocks power the Internet, defining the speed with which information can be sent and received. If your timepiece is very precise, it is easy to detect even small changes to its regularity. By measuring the motion of a physical object which is keeping time, such as the pendulum of a grandfather clock, and comparing it to an electronic reference, then we can detect disturbances, such as vibrations of the case

------------------------------------------------  3D microprinting counterfeit protection for products, passports, and money Security features are to protect bank notes, documents, and branded products against counterfeiting. Losses caused by product forgery and counterfeiting may be enormous. According to the German Engineering Association, the damage caused in 2016 in its branch alone amounted to EUR 7.3 billion. In the Advanced Materials Technologies journal, researchers of Karlsruhe Institute of Technology (KIT) and the ZEISS company now propose to use printed 3D microstructures instead of 2D structures, such as holograms, to improve counterfeit protection. "Today, optical security features, such as holograms, are frequently based on two-dimensional microstructures," says Professor Martin Wegener, expert for 3D printing of microstructures at the Institute of Nanotechnology of KIT. "By using 3D-printed fluorescent microstructures, counterfeit pr

It's generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To address this aspect, researchers demonstrate an epitaxy method that incorporates van der Waals' forces to grow germanium on mica.  Germanium, an elemental semiconductor, was the material of choice in the early history of electronic devices, before it was largely replaced by silicon. But due to its high charge carrier mobility -- higher than silicon by threefold -- the semiconductor is making a comeback. Germanium (Ge) is generally grown on expensive single-crystal substrates, adding another challenge to making it sustainably viable for most applications. To ad

------------------------------------------------ Pulling iron out of waste printer toner   Someday, left-over toner in discarded printer cartridges could have a second life as bridge or building components instead of as trash, wasting away in landfills and potentially harming the environment. One group reports in ACS Sustainable Chemistry & Engineering that they have devised a method to recycle the residual powder in "empty" cartridges into iron using temperatures that are compatible with existing industrial processes. Electronic waste is a broad category that encompasses everything from computers and televisions to ink cartridges and refrigerators. According to the European Toner and Inkjet Remanufacturers Association, 500 million cartridges out of the estimated 1.1 billion sold each year end up in landfills around the world. These "empty" cartridges can contain up to 8 percent of unused residual powder by weight and could

------------------------------------------------   Quantum computing with molecules for a quicker search of unsorted databases Grover's quantum algorithm successfully implemented -- superposition manipulated and read out electrically   Summary: Scrapbooks or social networks are collections of mostly unsorted data. The search for single elements in very large data volumes, i.e. for the needle in the data haystack, is extremely complex for classical computers. Scientists have now quantum mechanically implemented and successfully executed Grover's algorithm, a process for the quick finding of a search element in unsorted databases.  A universal quantum computer still is a vision. Special quantum systems that promise to solve certain tasks more quickly than a classical computer, however, are already playing an important role in science. To reliably find a certain element in unsorted data, a conventional computer has to run through all search elements suc
