For example, when placed alongside a battery in an electric car, a supercapacitor is useful when a short burst of power is required,
such as when overtaking another car, with the battery providing the steady power for highway driving. upercapacitors perform a similar function to batteries
and the paper lead author. heye much better at absorbing charge than batteries, but since they have much lower density,
and that might make them a high-power alternative to batteries. 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.
When the battery is charged, 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
and move back into the electrolyte. The reason why supercapacitors charge and discharge so much faster is that the tickingand oppingprocesses happen much faster than the chemical reactions at work in a battery. o increase the area for ions to stick to,
we fill the carbon electrode with tiny holes, like a carbon sponge, said Griffin. ut it hard to know what the ions are doing inside the holes within the electrode we don know exactly what happens
when they interact with the surface. In the new study, the researchers used NMR to look inside functioning supercapacitor devices to see how they charge and store energy.
They also used a type of tiny weighing scale called an electrochemical quartz crystal microbalance (EQCM) to measure changes in mass as little as a millionth of a gram.
By taking the two sets of information and putting them together, the researchers were able to build a precise picture of
what happens inside a supercapacitor while it charges. n a battery, the two electrodes are different materials,
so different processes are said at work Griffin. n a supercapacitor, the two electrodes are made of the same porous carbon sponge,
and see in detail exactly how the energy is stored, said Griffin. n the future we can look at how changing the size of the holes in the electrode
we can tailor the properties of both components to maximise the amount of energy that is stored.

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 metamaterial--like 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
increasing the velocity of the running wave. The nanostructure also acts like the boat's rudder, allowing the wakes to be steered by controlling the speed of the running wave.
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."
