Metasurface solves calculus problems as an analog computer
Detecting extraterrestrial life using mechanical nanosensors
Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait ...
Nanowire clothing could keep people warm—without heating everything else
To stay warm when temperatures drop outside, we heat our indoor spaces—even when no one is in them. But scientists have now developed a novel nanowire coating for clothes that can both generate heat and ...
Carbon nanotube finding could lead to flexible electronics with longer battery life
University of Wisconsin-Madison materials engineers have made a significant leap toward creating higher-performance electronics with improved battery life—and the ability to flex and stretch.
Graphene multiplies the power of light
Could graphene turn light to electricity? Scientists have shown that graphene can convert a single photon into multiple electrons, showing much promise for future photovoltaic devices.
DNA does design: 3D plasmonic photonic crystals are the first devices prepared by DNA-guided colloidal crystallization
Water-soluble silicon leads to dissolvable electronics
Smart keyboard cleans and powers itself—and can tell who you are (Update)
By analyzing such parameters as the force applied by key presses and the time interval between them, a new self-powered non-mechanical intelligent keyboard could provide a stronger layer of security for computer ...
Nanoscale neighbors: First use of transformation optics to accurately analyze nonlocality in 3D plasmonic systems
Researchers build an array of light detectors on a photonic chip able to record single photons
Zinc oxide materials tapped for tiny energy harvesting devices
Today, we're surrounded by a variety of electronic devices that are moving increasingly closer to us - we can attach and wear them, or even implant electronics inside our bodies.
From the bottom up: Manipulating nanoribbons at the molecular level
Narrow strips of graphene called nanoribbons exhibit extraordinary properties that make them important candidates for future nanoelectronic technologies. A barrier to exploiting them, however, is the difficulty ...
Silver nanowires demonstrate unexpected self-healing mechanism
With its high electrical conductivity and optical transparency, indium tin oxide is one of the most widely used materials for touchscreens, plasma displays, and flexible electronics. But its rapidly escalating ...
Researchers generate tiny images that contain over 300 colors
A scheme for greatly increasing the number of colors that can be produced by arrays of tiny aluminum nanodisks has been demonstrated by A*STAR scientists.
