#New electrode improves solar efficiency to split water Scientists from the Universities of Chicago and Wisconsin have developed a new type of electrode for splitting water with sunlight,
harvesting the hydrogen to be used as clean fuel. Sun-capturing electrodes are designed to absorb as much of the solar spectrum as possible to maximise efficiency.
However, they also need to facilitate the easy movement of electrons. Until now, scientists have had to use separate manipulations to increase photon absorption and electron transfer.
The new electrode, described in Nature Communications, is made primarily from the semiconducting compound bismuth vanadate.
some of which was incorporated into the electrode. This increased the efficiency of both photon absorption and electron transport.
This meant that more solar energy could be used by the electrode. ow we understand what going on at the microscopic level,

They've modelled an all-optical, CMOS-compatible transistor capable of 4thz speeds, potentially more than 1, 000 times faster than silicon transistors.
previous optical transistors have used electrical control and optics for data. This has inhibited the switching speed.
and according to the researchers, the optical transistors have a tunable dielectric permittivity compatible with all telecoms infrared (IR) standards. e are pretty far away from building anything resembling an processor.
In fact our transistor is only simulation at the current time, "said doctoral candidate Nate Kinsey, in conversation with El Reg."
He explained that one issue is that the transistor is controlled with UV LIGHT, and this is really not that practical for a highly integrated device.
We envisioned our switch being more of use for ultra-small signal encoding, say in like a data centre".

Through a new semiconductor material, gallium nitride (Gan. Already being used in LED light bulbs, television and computer displays,

They then patterned metal electrodes onto the flakes. In research done at Georgia Tech Wang's group installed measurement electrodes on samples provided by Hone's group then measured current flows as the samples were deformed mechanically.
They monitored the conversion of mechanical to electrical energy and observed voltage and current outputs. The researchers also noted that the output voltage reversed sign

Switching lighting to LEDS over the next two decades reports the U s. Department of energy could save the country $250 billion in energy costs over that period reduce the electricity consumption for lighting by nearly one half
White LED bulbs are already on store shelves but the light is generally colder than the warm glow of traditional bulbs.
They then used an electron microscope at Brookhaven to pin down the exact structures at each targeted moment in a kind of molecular time-lapse.
and novel semiconductors researchers at the Department of energy's Oak ridge National Laboratory have created a power inverter that could make electric vehicles lighter more powerful and more efficient.
At the core of this development is wide bandgap material made of silicon carbide with qualities superior to standard semiconductor materials.
Power inverters convert direct current into the alternating current that powers the vehicle. The Oak ridge inverter achieves much higher power density with a significant reduction in weight and volume.
Wide bandgap technology enables devices to perform more efficiently at a greater range of temperatures than conventional semiconductor materials said ORNL's Madhu Chinthavali who led the Power Electronics and Electric Machinery Group on this project.
This is especially useful in a power inverter which is the heart of an electric vehicle. Specific advantages of wide bandgap devices include:
higher inherent reliability; higher overall efficiency; higher frequency operation; higher temperature capability and tolerance; lighter weight enabling more compact systems;
and higher power density. Additive manufacturing helped researchers explore complex geometries increase power densities and reduce weight and waste while building ORNL's 30-kilowatt prototype inverter.
With additive manufacturing complexity is basically free so any shape or grouping of shapes can be imagined
Using additive manufacturing researchers optimized the inverter's heat sink allowing for better heat transfer throughout the unit.
Another key to the success is a design that incorporates several small capacitors connected in parallel to ensure better cooling
and lower cost compared to fewer larger and more expensive brick type capacitors. The research group's first prototype a liquid-cooled all-silicon carbide traction drive inverter features 50 percent printed parts.
Initial evaluations confirmed an efficiency of nearly 99 percent surpassing DOE's power electronics target
and setting the stage for building an inverter using entirely additive manufacturing techniques. Building on the success of this prototype researchers are working on an inverter with an even greater percentage of 3-D printed parts that's half the size of inverters in commercially available vehicles.
Chinthavali encouraged by the team's results envisions an inverter with four times the power density of their prototype.
Others involved in this work which was to be presented today at the Second Institute of Electrical
and Electronics Engineers Workshop on Wide Bandgap Power Devices and Applications in Knoxville were Curt Ayers Steven Campbell Randy Wiles and Burak Ozpineci.
Research for this project was conducted at ORNL's National Transportation Research center and Manufacturing Demonstration Facility DOE user facilities with funding from DOE's Office of Energy efficiency and Renewable energy.

#Beyond LEDS: Brighter, new energy saving flat panel lights based on carbon nanotubes Even as the 2014 Nobel prize in Physics has enshrined light emitting diodes (LEDS) as the single most significant and disruptive energy-efficient lighting solution of today scientists
around the world continue unabated to search for the even-better-bulbs of tomorrow. Enter carbon electronics.
Electronics based on carbon especially carbon nanotubes (CNTS) are emerging as successors to silicon for making semiconductor materials.
And they may enable a new generation of brighter low-power low-cost lighting devices that could challenge the dominance of light-emitting diodes (LEDS) in the future
and help meet society's ever-escalating demand for greener bulbs. Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes with very low power consumption of around 0. 1 Watt for every hour's operation
--about a hundred times lower than that of an LED. In the journal Review of Scientific instruments from AIP publishing the researchers detail the fabrication
and optimization of the device which is based on a phosphor screen and single-walled carbon nanotubes as electrodes in a diode structure.
Then they painted the mixture onto the positive electrode or cathode and scratched the surface with sandpaper to form a light panel capable of producing a large stable and homogenous emission current with low energy consumption.
Our simple'diode'panel could obtain high brightness efficiency of 60 Lumen per Watt which holds excellent potential for a lighting device with low power consumption said Norihiro Shimoi the lead researcher and an associate professor of environmental studies at the Tohoku University.
For instance LEDS can produce 100s Lumen per Watt and OLEDS (organic LEDS) around 40. Although the device has a diode-like structure its light-emitting system is not based on a diode system
which are made from layers of semiconductors materials that act like a cross between a conductor and an insulator the electrical properties
of which can be controlled with the addition of impurities called dopants. The new devices have luminescence systems that function more like cathode ray tubes with carbon nanotubes acting as cathodes
and an anode with the improved phosphor screen in our diode structure obtained no flicker field emission current and good brightness homogeneity Shimoi said.
The resistance of cathode electrode with highly crystalline single-walled carbon nanotube is very low. Thus the new flat-panel device has compared smaller energy loss with other current lighting devices
