It was designed for the microwave range with a 0. 6 cm thickness to handle 6 cm wavelengths, simply because those larger dimensions made it easier to work with.
But Kante points out that microwave cloaks could be useful for the military, to hide objects from radar working at such wavelengths.
Silicon-based materials can theoretically store more than 10 times charge than the carbon-based materials most commonly used in the anodes of commercial lithium-ion batteries,
making them promising next-generation anode materials. However, silicon big problem is that it can swell by more than 300 percent
causes the anode to crack. One way to overcome this problem is to make silicon porous enough to accommodate the expansion.
Now scientists have developed 3-D porous silicon-based anode materials using the kind of reed leaves that are abundant in temperate wetlands.
and made them into silicon-based anodes by heating them with magnesium and coating them with carbon.
and discharging, these anodes could store nearly three times more charge than carbon-based anodes; after 4, 000 such cycles,
they could still store more than 15 percent more than carbon-based anodes. The scientists detailed their findings online 26 june in the journal Angewandte Chemie International Edition l

The electrolyzer projects under construction in Germany typically consist of a few buildings each the size of a shipping container that consume excess renewable energy on sunny and windy days by turning it into an electric current that powers the water-splitting reaction.
That s where electrical engineer Ada Poon and her team at Stanford university say they might be able to help.
The group has developed a new method of sending magnetic fields well below skin level to power devices that would
and derive power from electromagnetic induction in which a current running through a coil of wire generates a magnetic field that then induces a current in a nearby device.
The problem is that a field generated this way decays exponentially with distance from the generating coil so it only works with devices close to the skin s surface.
Poon and her team found a way to use electromagnetic induction through biological tissue without that exponential decay.
When they send current through the plate that pattern produces a magnetic field capable of propagating through biological material without decaying over a short distance.

Eventually, Prakash decided to build a rotating magnetic field that could act as clock to synchronize all the droplets.
Prakash realized that a rotating magnetic field might do the trick. Katsikis and Prakash built arrays of tiny iron bars on glass slides that look something like a Pac-Man maze.
Next, they turned on the magnetic field. Every time the field flips, the polarity of the bars reverses, drawing the magnetized droplets in a new, predetermined direction, like slot cars on a track.
Combined with the fact that the magnetic field can control millions of droplets simultaneously this makes the system exceptionally scalable."

At its most basic level, a battery is made of two metal electrodes (an anode and a cathode) with some sort of solution between them (electrolyte.
electrolyte ions are stored in the anode. As the battery discharges, electrolyte ions leave the anode
and move across the battery to chemically react with the cathode. The electrons necessary for this reaction travel through the external circuit,
generating an electric current. A supercapacitor is similar to a battery in that it can generate and store electric current,
but unlike a battery, the storage and release of energy does not involve chemical reactions: instead, positive and negative electrolyte ions simply tickto the surfaces of the electrodes when the supercapacitor is being charged.
When a supercapacitor is being discharged to power a device, the ions can easily opoff the surface
