The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.

The foams are made by depositing copper on a surface in the presence of hydrogen and a strong electric current.

Band gaps determine how a semiconducting material carries an electric current. In quantum dots microscopic discs of atom-thick graphene oxide band gaps are responsible for their fluorescence

This flow of electrons is electric current. But to establish a consistent direction of their movement

which then causes the material to glow emitting light that can in turn be converted to an electric current.

these molecules, found in the bacteria Haloarcula marismortui and Haloarcula vallismortis, did not induce a strong enough photocurrent an electric current in response to light to be useful in controlling neuron activity.

An electric current delivered by the device removes the membrane, releasing a single dose. The device can be programmed wirelessly to release individual doses for up to 16 years to treat

Broadly speaking organic solar cells convert light into electric current in four steps. First the cell absorbs sunlight which excites electrons in the active layer of the cell.

catalyzed by the gold releases electrons generates an easily measurable electric current. The gold nanotubes conduct electricity especially well due to their one-dimensional structure.

You put a hydrogen-containing gas on one side apply small electric current and collect pure hydrogen on the other side.

and the nanowires are grown by applying electric current through electrodeposition. Nath grows the nanowires in a parallel pattern

And depending on the materials involved and the electric current, the bridge formed in different ways. The bridge, also called a conducting filament,

This allows those charges to be collected at the edge of the film where they can be harnessed to provide an electric current.

When an electric current is applied to one of the DEAS it creates a biased stress between the two DEAS thus bending the actuator.

which produces an electric current when exposed to light. This mechanism enables each pixel to measure the intensity of light falling on it.

An electric current magnetizes the coil inside the reader, and that magnetic field creates a voltage in the sensor coil

In the ICFO device, the continued excitation of electrons above this band-gap level results in the much faster and easier movement of them when subjected to incoming photons to create an electric current.

the most common function of such a diode is to permit electric current to flow in one direction only,

Students can use the marker as an educational tool to easily experiment on electric currents and,

"More than 80%of the incident visible sunlight was converted photoelectrically by this composite system into electric current available for the hydrogen generation,

and the atomic structure in the nanotubes halts electric currents. This disparity creates a barrier, caused by the difference in electron movement as currents move next to and past the hairlike boron nitride nanotubes.

and convert the light into electric current using excited states in the material called"excitons.""Roughly speaking, an exciton is displaced a electron bound together with the hole it left behind.

This influences the motion of the electron, resulting in an electric current that the researchers can measure.

so that their ability to carry an electric current changes in the presence of a particular gas.

and oxygen by running an electric current through water, could be used to inexpensively power our homes

when exposed to an electric current. The group first developed a technique to create a film of aligned carbon nanotubes composed of tiny tubes of crystalline carbon

#From metal to insulator and back again Metals are compounds that are capable of conducting the flow of electrons that make up an electric current.

Other materials, called insulators, are not capable of conducting an electric current. At low temperatures, all materials can be classified as either insulators or metals.

Nanopore technology, currently under development by many private enterprises, distinguishes individual nucleic acids by the distinctive perturbations they create in electric currents as they pass through microscopic pores.

But materials that exhibit thermoelectric properties the ability to convert heat to electric current tend to work only at higher temperatures than those seen in engines.

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.

The Columbia scientists, working with researchers in South korea, attached small strips of graphene to microscopic metal electrodes which passed an electric current through the suspended strips causing them to heat up and bright

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.

An electric current delivered by the device removes the membrane, releasing a single dose. The device can be programmed wirelessly to release individual doses for up to 16 years to treat

Once fully developed, the armour could transform from a liquid to a solid in a fraction of a second when under the influence of a magnetic field, or electric current.

EAV is a form of acupuncture where a small electric current is passed between pairs of electrodes.

when an electric current is applied.""By means of the innovative production process we developed together with our industry partner,

According to the researchers, the vanadium flow battery works especially well with their hybrid electrode, allowing them to boost the electric current,

which run on light rather than electric current. The problem has been one of size and temperature incandescent filaments must get extremely hot before they can produce visible light.

When electric current is passed through an incandescent light bulb's filament usually made of tungsten the filament heats up and glows.

which can be moved out of the way by delivering an electric current. Each reservoir can be activated individually to open up depending on the applied current,

and Mark Ratner who theorized in 1974 that a molecule could act as a rectifier, a one-way conductor of electric current.

when heated by an electric current, the researchers could then stretch the nanowire in a controlled way.
