#Japanese Paper Cutting Trick for Moving Solar cells To maximize the amount of electricity that solar cells generate,
solar panels can be tilted to track the position of the sun over the course of a day.
Conventional solar trackers can increase yearly energy generation by 20 to 40 percent, but they can be costly,
Now materials scientist Max Shtein and his colleagues at the University of Michigan at Ann arbor have developed novel solar cells that integrate tracking into their design.
The scientists cut kirigami designs into a 3-micron-thick flexible crystalline gallium arsenide solar cells mounted on plastic sheets.
A solar cell array of this type can tilt in three dimensions in a highly controllable manner
The researchers found that their new devices could generate roughly as much power as solar cells mounted on conventional trackers.
Shtein and his colleagues suggest that kirigami solar panels could be simple, inexpensive and lightweight, and have widespread rooftop, mobile,
whether mounting solar cells onto more durable materials such as spring steel could make kirigami systems even more robust t
Measuring Electrical resistance Graphene merits in electronic devices and as a light bulb coating are still being debated. But new results suggest the atom-thick carbon sheet has one clear advantage:
namely the big spacing between electron energy levels when the material is exposed to a magnetic field,
said Langhammer. his usually means focusing a beam of high-energy electrons or photons or a mechanical probe onto a very tiny volume.

Researchers at Vanderbilt University have used silver nanowires to fabricate a metamaterial that is capable of detecting polarized light in a way not unlike the way cuttlefish, bees,
These plasmon density waves absorb energy from the photons that pass through the silicon wafer. The absorption of the energy produces otor energetic electrons,
which generate a detectable electrical current. The researchers found that they could make the zigzag pattern of nanowires with a right-or left-handed orientation.
so switching would require less energy. One way that scientists have sought to overcome this limit is with tunnel FETS (TFETS.
This led to a more than 90 percent reduction in power consumption compared with conventional FETS. The scientists and engineers detailed their findings in the 1 oct. issue of the journal Nature. his transistor represents a major breakthrough in the electronics and semiconductor industry

RF accelerators can reach energies of a few tens of mega electron volts before the RF energy itself begins to destabilize the mechanism in what called plasma breakdown.
In wakefield approaches, balancing the skittish plasma bubble requires terawatt or petawatt lasers, tricky micromachinging,
the frequency is high enough that the plasma breakdown threshold for surface electric fields increases The terahertz approach also allows them to use readily available picoseconds lasers.
however, boosted their energy to 67 kev. A back of the envelope calculation translates this modest energy gain into an acceleration gradient over 2 Mev/m. his is not a particularly large acceleration,
but the experiment demonstrates that the principle does work in practice, explains co-author Arya Fallahi of CFEL. he theory indicates that we should be able to achieve an accelerating gradient of up to one gigavolt per meter.
Phosphorescent OLEDS (PHOLEDS) use only one quarter the energy of conventional OLEDS. Green and red PHOLEDS are used already in smartphones and TVS
leading to longer battery lives and lower electricity bills, but developing the kind of bright deep blue PHOLEDS needed for video displays has proven challenging.

#First aqueous solar flow battery designed WASHINGTON: Researchers have designed the first aqueous flow battery with solar capability that can achieve a 20 per cent energy savings over traditional batteries.
Researchers at The Ohio State university had developed the world's first solar air battery last Fall in a new study,
the researchers have reported that their patent-pending design -which combines a solar cell and a battery into a single device-now achieves a 20 per cent energy savings over traditional lithium-iodine batteries.
The 20 per cent comes from sunlight, which is captured by a unique solar panel on top of the battery,
said Yiying Wu, professor at Ohio State. The solar panel is a solid sheet, rather than a mesh as in the previous design.
Another key difference comes from the use of a water-based electrolyte inside the battery.
Because water circulates inside it, the new design belongs to an emerging class of batteries called aqueous flow batteries."
"The truly important innovation here is that we've successfully demonstrated aqueous flow inside our solar battery,
"Wu said. As such, it is the first aqueous flow battery with solar capability. Or, as Wu and his team have dubbed it, the first"aqueous solar flow battery."
"It's also totally compatible with current battery technology, very easy to integrate with existing technology,
environmentally friendly and easy to maintain, "he added. Researchers around the world are working to develop aqueous flow batteries
because they could theoretically provide affordable power grid-level energy storage someday. The solar flow battery could thus bridge a gap between today's energy grid and sources of renewable energy."
"This solar flow battery design can potentially be applied for grid-scale solar energy conversion and storage, as well as producing'electrolyte fuels'that might be used to power future electric vehicles,
"said Mingzhe Yu, lead author of the paper and a doctoral student at Ohio State. The new solid solar panel is called a dye-sensitised solar cell,
because the researchers use a red dye to tune the wavelength of light it captures
and converts to electrons. Those electrons then supplement the voltage stored in the lithium-anode portion of the solar battery.
To carry electrons from the solar cell into the battery a liquid electrolyte is required, which is typically part salt, part solvent.
The researchers used lithium iodide as the salt, which offers a high-energy storage capacity with low cost,
and water as the solvent. In tests, the researchers compared the solar flow battery's performance to that of a typical lithium-iodine battery.
They charged and discharged the batteries 25 times. Each time, both batteries discharged around 3. 3 volts.
The difference was that the solar flow battery could produce the same output with less charging.
The study was published in Journal of the American Chemical Society. WASHINGTON: Researchers have designed the first aqueous flow battery with solar capability that can achieve a 20 per cent energy savings over traditional batteries.

#Cells that regenerate liver without cancer risk NEW YORK: Scientists have discovered new type of cells which are an important part of liver regeneration.
When healthy liver cells are depleted by long-term exposure to toxic chemicals, the newly discovered cells,
known as hybrid hepatocytes, generate new tissue more efficiently than normal liver cells. Importantly, they divide
and grow without causing cancer, which tends to be a risk with rapid cell division.""Hybrid hepatocytes represent not only the most effective way to repair a diseased liver,
but also the safest way to prevent fatal liver failure by cell transplantation,"lead researcher professor Michael Karin from University of California, San diego (UCSD) School of medicine.
The liver is the only organ regenerates after being damaged. Exactly how it repairs itself remained a mystery until recently,
when researchers discovered a type of cell in mice essential to the process. The researchers also found similar cells in humans.
The researchers studied liver function in mice. They were able to isolate the hybrid hepatocytes after observing how the tissue regenerated.
They then exposed healthy mice to three known cancer-causing pathways and watched the hybrid hepatocytes closely.

#ORNL unveils integrated 3d printed house and car that produce and share clean energy Two of the most pressing and discussed issues facing the world today include the global housing crisis,
with more than 800 million people forced to live in slums, and our grotesque reliance on nonrenewable energy sources,
which has led to the depletion of Earth resources and has increased dramatically global warming. 3d printing technology has made already huge contributions to address both of these concerns individually,
however energy waste in manufacturing, buildings and transportation is connected fundamentally real breakthrough means solving them together rather than separately.
At today EERE day, The Oak ridge National Laboratory unveiled its Additve Manufactuing Integrated Energy (AMIE) project,
a first-of-its-kind design that uses an integrated symbiotic energy system to share energy between a single-unit, 3d printed solar powered house and a 3d printed electric car.
AMIE could support worldwide electricity needs, completely revolutionizing how we generate, use and store clean energy.
Thanks to a collaboration between more than 20 major industry partners and with the innovative use of 3d printing technology
The team took advantage of 3d printing instant feedback and rapid prototyping to experiment with new shapes, printing speeds, battery technologies, cleaner burning fuels,
and maximize energy savings. t the flexibility of this printed platform that allows us to explore all of those opportunities,
however the true innovation comes from the integrated energy-sharing platform, which uses a bidirectional wireless charger to direct energy to and from the car or house as needed.
The project energy control center manages the system electrical demand and load by balancing the intermittent power from the buildin 3. 2 kw solar array with supplemental power from the vehicle.
In essence this approach was designed to take advantage of the fact that even though we aren using our car and our house every minute of the day,
they can still be generating and storing energy. So, while it is sunny outside, the house produces its own solar energy,
and at night or on cloudy days, the natural-gas-powered hybrid electric car can provide supplemental power.
