#New metamaterial enables refractive index of zero Researchers at the Harvard John A. Paulson School of engineering and Applied sciences (SEAS) say they have made it easier to manipulate light at the nanoscale.
They have developed the first on-chip metamaterial with a refractive index of zero, meaning that the phase of light can travel infinitely fast.
The new metamaterial was developed in the lab of Eric Mazur, the Balkanski Professor of Physics and Applied Physics and Area Dean for Applied Physics AT SEAS,
The metamaterial consists of low-aspect-ratio silicon pillar arrays embedded in a polymer matrix and clad by gold films.

#Aluminum-Ion Batteries Are Flexible, Fast-Charging, And Won't Catch on Fire Almost all of the electronic devices that we carry around with us all day now rely on one key,
the lithium-ion battery. A mainstay of rechargeable power for the last couple decades, this battery technology has gotten only minor refinements.
But a substantial improvement in stored power may be in the offing, thanks to researchers at Stanford university,
who have developed a new battery technology based on aluminum. This isn't the first time that aluminum-based batteries have been investigated.
The material has a number of advantages over lithium: it's flexible, allowing it to be folded
you can even drill a hole through the battery and it will continue to work.
compromise a lithium-ion battery and you'll likely see some sparks or flame, but the materials in this new battery are all non-reactive.
And, aluminum is cheaper than lithium, too. All good things, so why haven't we seen more aluminum batteries?
The catch to date has been finding another material to work with aluminum in creating energy. The Stanford team ended up using our old friend graphene to play the cathode to aluminum's anode.
But though that's helped unlock better performance, including more charge cycles--7, 500 versus the 1,
000 you'd likely get out of a Li-ion battery--aluminum-ion's woes aren't all behind it.
The voltage provided by an aluminum-ion battery is only about half of that what you'd get from a lithium-ion cell.
the overall power density--the amount of juice you can store in a battery vis-a-vis its size--more closely resembles the large lead-acid battery you'd find in your car.
So aluminum-ion batteries still aren't quite ready for primetime, but you can bet that electronics manufacturers, makers of electric cars,
and power companies all have their eyes on the development of this technology. Meanwhile, researchers are working to enhance the performance of lithium-ion batteries using materials like carbon nanotubes,
but the returns are diminishing. And other new technologies, like sulfur-based and metal-air batteries have their own downsides as well.
Should scientists be able to increase the power and energy density of aluminum-ion batteries its speed of charging, lack of volatility,
and cheap production costs could make it the one to beat t

Today at the Space Symposium in Colorado, the company unveiled its brand-new engine, named Rutherford--the first-ever battery-powered rocket engine.
But with Rutherford, the engines turbopumps get a much more condensed energy source. Instead of running on liquid propellant, the pumps are powered by electric motors with lithium polymer batteries.

#Organic framework serves as catalyst for the photocatalytic conversion of water into hydrogen Humanity's need for energy is ever-increasing.
However, the traditional energy sources are finite. In contrast, water and sunlight are available in vast abundance.
Scientists at the Max Planck Institute for Solid State Research in Stuttgart and from LMU Munich have created now a material that uses light to produce the versatile energy source hydrogen from water.
What is needed is a substance that directly uses the energy of sunlight to split the hydrogen-oxygen bonds in water.

Hydrogen which is used currently in the industry to manufacture many important chemicals could also be made available in a more sustainable fashion.
#Shortening Organic solar cell Production One of the building blocks of the solar panel, solar cells are responsible for converting solar energy into electricity.
Most commercial solar cells are made from the inorganic crystalline silicon. Now, the U s. Dept of energy (DOE) Oak ridge National Laboratory (ORNL) has developed a method to save steps in the organic solar cell manufacturing process by introducing solvents into solar cell film production.
Usually, the thin filmssed by organic bulk heterojunction solar cellsre created by mixing conjugated polymers and fullerenes,

#New design points a path to the ltimatebattery Scientists have developed a working laboratory demonstrator of a lithium-oxygen battery
or lithium-air, batteries have been touted as the'ultimate'battery due to their theoretical energy density, which is ten times that of a lithium-ion battery.
Such a high energy density would be comparable to that of gasoline -and would enable an electric car with a battery that is a fifth the cost and a fifth the weight of those currently on the market to drive from London to Edinburgh on a single charge.
However, as is the case with other next-generation batteries, there are several practical challenges that need to be addressed before lithium-air batteries become a viable alternative to gasoline.
Now, researchers from the Univ. of Cambridge have demonstrated how some of these obstacles may be developed overcome,
and a lab-based demonstrator of a lithium-oxygen battery which has increased higher capacity energy efficiency and improved stability over previous attempts.
Their demonstrator relies on a highly porous, 'fluffy'carbon electrode made from graphene (comprising one-atom-thick sheets of carbon atoms),
and additives that alter the chemical reactions at work in the battery, making it more stable and more efficient.
While the results, reported in Science, are promising, the researchers caution that a practical lithium-air battery still remains at least a decade away."
"What we've achieved is a significant advance for this technology and suggests whole new areas for researche haven't solved all the problems inherent to this chemistry,
but our results do show routes forward towards a practical device, "said Prof. Clare Grey of Cambridge's Dept. of Chemistry, the paper's senior author.
Many of the technologies we use every day have been getting smaller, faster and cheaper each yearith the notable exception of batteries.
the challenges associated with making a better battery are holding back the widespread adoption of two major clean technologies:
electric cars and grid-scale storage for solar power.""In their simplest form, batteries are made of three components:
a positive electrode, a negative electrode and an electrolyte,''said Dr. Tao Liu, also from the Dept. of Chemistry,
and the paper's first author. In the lithium-ion (Li-ion) batteries we use in our laptops and smartphones,
the negative electrode is made of graphite (a form of carbon), the positive electrode is made of a metal oxide, such as lithium cobalt oxide,
and the electrolyte is a lithium salt dissolved in an organic solvent. The action of the battery depends on the movement of lithium ions between the electrodes.
Li-ion batteries are light but their capacity deteriorates with age, and their relatively low energy densities mean that they need to be recharged frequently.
Over the past decade, researchers have been developing various alternatives to Li-ion batteries, and lithium-air batteries are considered the ultimate in next-generation energy storage, because of their extremely high energy density.
However, previous attempts at working demonstrators have had low efficiency, poor rate performance, unwanted chemical reactions, and can only be cycled in pure oxygen.
What Liu, Grey and their colleagues have developed uses a very different chemistry than earlier attempts at a non-aqueous lithium-air battery
relying on lithium hydroxide (Lioh) instead of lithium peroxide (Li2o2. With the addition of water and the use of lithium iodide as a'mediator',their battery showed far less of the chemical reactions
which can cause cells to die, making it far more stable after multiple charge and discharge cycles.
and changing the chemical makeup of the electrolyte, the researchers were able to reduce the'voltage gap'between charge
A small voltage gap equals a more efficient batteryrevious versions of a lithium-air battery have managed only to get the gap down to 0. 5 to 1. 0 V
whereas 0. 2 V is closer to that of a Li-ion battery, and equates to an energy efficiency of 93%.
%The highly porous graphene electrode also greatly increases the capacity of the demonstrator, although only at certain rates of charge and discharge.
which can cause batteries to explode if they grow too much and short-circuit the battery. Additionally, the demonstrator can only be cycled in pure oxygen,
while the air around us also contains carbon dioxide, nitrogen and moisture, all of which are generally harmful to the metal electrode."
Finally, that nitrogen lowered the energy needed to kick electrons into the state in which they were available to split water.
use it to drive turbines and then be reheated to continue the cycle. Most commonly this might be done over a 24-hr period, with variable levels of solar-powered electricity available at any time of day
as dictated by demand. The findings have been published in Chemsuschem. The work was supported by the Sunshot Initiative of the U s. Dept of energy,
Conceptually, all of the energy produced could be stored indefinitely and used later when the electricity is needed most.
Alternatively, some energy could be used immediately and the rest stored for later use. Storage of this type helps to solve one of the key factors limiting the wider use of solar energyy eliminating the need to use the electricity immediately.
The underlying power source is based on production that varies enormously not just night and day, but some days,
or times of day, that solar intensity is more or less powerful. Many alternative energy systems are constrained by this lack of dependability and consistent energy flow.
Solar thermal electricity has been of considerable interest because of its potential to lower costs. In contrast to conventional solar photovoltaic cells that produce electricity directly from sunlight, solar thermal generation of energy is developed as a large power plant in
which acres of mirrors precisely reflect sunlight onto a solar receiver. That energy has been used to heat a fluid that in turn drives a turbine to produce electricity.
Such technology is appealing because it safe long-lasting, friendly to the environment and produces no greenhouse gas emissions.
Cost, dependability and efficiency have been the primary constraints. ith the compounds wee studying, there significant potential to lower costs and increase efficiency, said Nick Auyeung, an assistant professor of chemical engineering in the OSU College of Engineering, corresponding author on this study,
and an expert in novel applications and use of sustainable energy. n these types of systems, energy efficiency is closely related to use of the highest temperatures possible,
According to Auyeung, thermochemical storage resembles a battery, in which chemical bonds are used to store and release energyut in this case,
the transfer is based on heat, not electricity. The system hinges on the reversible decomposition of strontium carbonate into strontium oxide and carbon dioxide,
In comparison to existing approaches, the new system could also allow a 10-fold increase in energy densityt physically much smaller
which would drive a turbine to produce electricity, and then residual heat could be used to make steam to drive yet another turbine.
In laboratory tests, one concern arose when the energy storage capacity of the process declined after 45 heating and cooling cycles, due to some changes in the underlying materials.
The researchers'analysis found that this energy-consuming intermediary step is not necessary for the conversion to happen.
Instead, an energy-producing"hydrocarbon pool"mechanism allows the zeolite catalysts to directly produce longer hydrocarbon chains from the original alcohols."
and requires energy. We showed this step doesn't occur, and that the overall reaction is slightly exothermic."
The research, supported by DOE's Bioenergy Technologies Office, has implications for the energy efficiency and cost of catalytic upgrading technologies proposed for use in biorefineries.
Uncovering the mechanism behind the reaction helps support the potential economic viability of ORNL's direct biofuel-to-hydrocarbon conversion approach."
