#World's Thinnest Light bulb Created from Graphene Graphene, a form of carbon famous for being stronger than steel
Researchers have developed a light-emitting graphene transistor that works in the same way as the filament in a light bulb."
what is essentially the world's thinnest light bulb, "study co-author James Hone, a mechanical engineer at Columbia University in New york, said in a statement.
Scientists have wanted long to create a teensy"light bulb"to place on a chip, enabling what is called photonic circuits,
giving them energy. Those electrons return to their former energy levels and emit photons (light) in the process.
Crank up the current and voltage enough and the filament in the light bulb hits temperatures of about 5, 400 degrees Fahrenheit (3, 000 degrees Celsius) for an incandescent.
This is one reason light bulbs either have no air in them or are filled with an inert gas like argon:
At those temperatures tungsten would react with the oxygen in air and simply burn. In the new study, the scientists used strips of graphene a few microns across and from 6. 5 to 14 microns in length, each spanning a trench of silicon like a bridge.
#Novel Use of WI-FI Signals to Power Remote Devices, named Powi-Fi The scientists from the University of Washington have devised a method to utilize Wi-fi signals to power a battery-free camera,
an Indian origin scientist along with colleagues at the University of Washington in Seattle have asserted that Wi-fi radio broadcasts are a form of energy
and a simple antenna with the receivers can pick up this energy. Talla demonstrated his claim by connecting an antenna to a temperature sensor
Talla informed,"The battery-free camera can operate up to about five meters from the router,
"Talla further said that by adding a rechargeable battery, the operating distance of the camera was increased to seven meters.
Harvesting Power from Vapours The clean energy sources have got an addition on their list, with the researches at the University of Columbia devising the world's first evaporation-driven engine that runs by harvesting energy from the evaporating water.
The study published in the journal Nature Communications today employed the bacterial spores to harness this energy.
Peter Fratzl, biomaterial researcher at the Max Planck Institute of Colloids and Interfaces, stated, "This is not the first time that evaporation energy has been captured,
but it is the first time that it has been done a scale where objects could be moved. The work pushes a great idea all the way into a practical demonstration of the potential".
their movement was used to create energy that powered an engine which could run LED LIGHTS and even drive a miniature car!
Fratzl further asserted that this is a very impressive breakthrough as the engine is essentially harvesting useful amounts of energy from the infinitely small
#Novel Approach for Lithium-ion Batteries Researchers from MIT and Cambridge, Mass. -based Battery Company 24m have come up with an advanced manufacturing technology for lithium-ion batteries.
Researchers have claimed of reinvented the process for manufacturing lithium-ion batteries. Not much change has been noticed in the manufacturing of lithium-ion batteries in the two decades.
Yet-Ming Chiang, the Kyocera Professor of Ceramics at MIT, was of the view that the existing technology is not perfect
and there is a need to made advancements. Five years back, Chiang and colleagues developed the new process.
and pumped through different compartments of the battery. Scientists said that the new battery design is a hybrid between flow batteries and conventional ones.
The research published in the Journal of Power Sources unveiled that the new approach has simplified manufacturing.
Also, the batteries become flexible and resistant to damage. Research paper'senior author Chiang said that after presenting the earlier research on the flow battery,
"We realized that a better way to make use of this flowable electrode technology was to reinvent the lithium ion manufacturing process".
The new system leads to the production of battery that is more flexible and resilient. Around 10,000 batteries have been made by the company on its prototype assembly lines.
They will undergo testing by three industrial partners s

#Electromagnetic field Activated Drug Loadded Nanowires Drug releasing implants can be of great benefit for conditions requiring long term treatment in a targeted area of the body.
Applying an electromagnetic field over the wires caused them to release the drug. Turning off the EM field immediately stopped the drug release process.
The corticosteroid DEX, a powerful ameliorator of inflammation, was released from the polymer by external application of an electromagnetic field for 2 h/day for a week.

For instance, the basic principle here could be used to build power plants over bodies of water that generate electricity as the water evaporates.
Mercedes-benz and Hyundai. Think of a fuel-cell car as an exhaust-free electric car with a little chemical factory producing the electrons in place of a battery.
The other advantage over battery cars is that refueling is just like getting gas, and takes only about five minutes.

a bladeless wind turbine that looks like a giant rolled joint shooting into the sky. The Vortex has the same goals as conventional wind turbines:
To turn breezes into kinetic energy that can be used as electricity. But it goes about it in an entirely different way.
Instead of capturing energy via the circular motion of a propeller, the Vortex takes advantage of what known as vorticity,
an aerodynamic effect that produces a pattern of spinning vortices. Vorticity has long been considered the enemy of architects and engineers,
hy don we try to use this energy, not avoid it,?Suriol says. The team started Vortex Bladeless in 2010 as a way to turn this vibrating energy into something productive.
The Vortex shape was developed computationally to ensure the spinning wind (vortices) occurs synchronously along the entirety of the mast. he swirls have to work together to achieve good performance,
This kinetic energy is converted then into electricity via an alternator that multiplies the frequency of the mast oscillation to improve the energy-gathering efficiency.
Based on field testing, the Mini ultimately captures 30 percent less than conventional wind turbines, but that shortcoming is compensated by the fact that you can put double the Vortex turbines into the same space as a propeller turbine.
The Vortex team says there are some clear advantages to their model: It less expensive to manufacture, totally silent,
Vortex Bladeless says its turbine would cost around 51 percent less than a traditional turbine whose major costs come from the blades and support system.
There enough interest, Suriol says, that he fields upward of 200 emails a day from people inquiring about the turbine.

"A big focus of our lab is just studying electricity in the form of how electrons move around
Since a diode acts as an electricity valve, its structure needs to be asymmetric so that electricity flowing in one direction experiences a different environment than electricity flowing in the other direction.
In order to develop a single-molecule diode, researchers have designed simply molecules that have asymmetric structures.""While such asymmetric molecules do indeed display some diode-like properties,
Electrons that are driven toward the center absorb enough energy so that some of them emit blue light at double the frequency of the incoming infrared light. his is similar to

For the first time, Harvard researchers have created similar wakes of light-like waves moving on a metallic surface, called surface plasmons,
"The creation and control of surface plasmon wakes could lead to new types of plasmonic couplers
Surface plasmons are confined to the surface of a metal. In order to create wakes through them, Capasso's team designed a faster-than-light running wave of charge along a one-dimensional metamaterialike a powerboat speeding across a lake.
The metamaterial, a nanostructure of rotated slits etched into a gold film, changes the phase of the surface plasmons generated at each slit relative to each other
The team discovered that the angle of incidence of the light shining onto the metamaterial provides an additional measure of control
as"surface plasmons are not visible to the eye or cameras,"said co-lead author Antonio Ambrosio of SEAS and the Italian Research Council (CNR)."
we used an experimental technique that forces plasmons from the surface, collects them via fiber optics and records the image."
