High performance, lightweight supercapacitor electrodes of the future
These are high performance supercapacitor electrodes. Left: field emission scanning electron microscope and transmission electron microscope micrographs; Right: sectional view of single hybrid nanostructure. Many scientists are working to develop green, lightweight, low-cost supercapacitors with high performance, and now two researchers have developed a novel supercapacitor electrode based on a hybrid nanostructure made from a hybrid nickel oxide-iron oxide exterior shell and a conductive iron-nickel core. Its core/shell structure could mean faster charging time and longer battery life in electric vehicles and portable electronics

Flexible sensors turn skin into a touch-sensitive interaction space for mobile devices
Scientists have developed stickers with pressure-sensitive sensors that fit snugly to the skin. By operating the touch input stickers, users can use their own body to control mobile devices. If a mobile phone rings during a meeting, its owner often has to dig it out before it can be muted. A more discreet method would be to decline the incoming call by pressing on one of your fingers. Scientists are studying the potential use of the human body as a touch sensitive surface for controlling mobile devices. They have developed flexible silicone rubber stickers with pressure-sensitive sensors that fit snugly to the skin. By operating these touch input stickers, users can use their own body to control mobile devices. Because of the flexible material used, the sensors can be manufactured in a variety of shapes, sizes and personalized designs.

Defects in solar cells made of silicon identified

Scientists measure speedy electrons in silicon
In semiconductors like silicon, electrons attached to atoms in the crystal lattice can be mobilized into the conduction band by light or voltage. scientists have taken snapshots of this very brief band-gap jump and timed it at 450 attoseconds. Attosecond lasers provide the shortest light pulses yet, allowing observation of nature's most short-lived events. Researchers have used these lasers for the first time to take snapshots of electrons jumping from silicon atoms into the conduction band of a semiconductor, the key event behind the transistor. They clocked the jump at 450 attoseconds and saw the rebound of the crystal lattice 60 femtoseconds later: a delay 120 times longer than the jump itself.
Germanium Semiconductor milestone
This graphic depicts a new electronic device created at Purdue that uses germanium as the semiconductor instead of silicon. Germanium is one material being considered to replace silicon in future chips because it could enable the industry to make smaller transistors and more compact integrated circuits.
A laboratory at Purdue University provided a critical part of the world's first transistor in 1947 -- the purified germanium semiconductor -- and now researchers there are on the forefront of a new germanium milestone. The team has created the first modern germanium circuit -- a complementary metal-oxide-semiconductor (CMOS) device -- using germanium as the semiconductor instead of silicon.

Researchers Control a Material with Voltage
This diagram shows the principle behind using voltage to change material properties. In this sandwich of materials, applying a voltage results in movement of ions electrically charged atoms from the middle, functional layer of material into the target layer. This modifies some of the properties magnetic, thermal, or optical of the target material, and the changes remain after the voltage is removed.

Scientists Develop a Nanolamp with a Lightning-Fast Switch
Researchers at the Max Planck Institute for Solid State Research apply a voltage between a gold surface coated with a layer of spherical carbon molecules and the tip of a scanning tunneling microscope. The resulting electric field (indicated by the grey arrows in the diagram) can be regulated by the level of the voltage and the distance between the tip and the metal surface. With a particular field strength, the single molecule (in magenta) becomes electrically charged, which immediately leads to electrical energy being converted to light (the yellow wave).
