It consists of a negative electrode (cathode) and a positive electrode (anode), with a vacuum between them.
The whole device, together with a second electrode (known as a reference) to complete the circuit, is then mounted on a stick.
Protons left behind by the oxygen migrated to a second electrode made of platinum and formed into hydrogen.
ECONOMIST: Looking to leaves for a way to store solar power after sunset
By adding cobalt and phosphates to water and passing a mild current through the solution with a glass electrode, Matthew Kanan and Daniel Nocera of the Massachusetts Institute of Technology (MIT) were able to break water apart and force oxygen to bubble to the surface.

It consisted of a 100-electrode panel about the size of a baby aspirin that was placed on the surface of the brain at a fold in the motor cortex where hand movement is controlled.
Making a deviced structure through the thin film process for semiconductors, the performance as a photo-electrode has highly improved.
The inquest heard that midwives did not regularly check her labour progress and after bringing a foetal scalp electrode to monitor the baby they found he had already been born and starved of oxygen.
If a chemical or biological agent binds to the electrode, it triggers a signal.
Each electrode trailed a color-coded wire, which got plugged into what looked like a backgammon board.
The electrons are passed via a semiconductor to an electrode, through which they leave the cell.
A123 has developed a battery that uses a doped lithium nanophosphate electrode (cathode) that eliminates combustible oxygen from the system.
It works by using a power source to pump 10 kV of juice to an electrode, which then polarizes a dielectric plate, causing it to attract your body hair.
An epilepsy patient could have a pacemaker for the brain: An electrode array like Donoghue's could pick up signals that lead to a seizure, and a stimulator could fire and reset the brain before the seizure takes hold.
Following that tradition, the brainiacs over at the University of Reading have developed a new nano-material electrode coating based on the cellular structure of plants.

Eight young women squirm under electrode-studded caps in a dark, small room in Greenwich, England.
Starting with a small piece of frost on an electrode, he has grown ice stars and flowery stalks of impressive beauty.
In the top diagram the solar panel is completely exposed to a light source 1804 and all six electrode quadrants 1802 are producing electricity more or less equally.

When spot-welding, for instance, a robot has to touch the metal with an electrode.
The result was that the electrode turned from oxide to metal in a way that would have pleased a medieval alchemist.
Dr Legrand, however, has developed an evolution-based system that co-evolves several channels at a time, allowing a patient to tell his doctor how each pattern of electrode stimulation is faring.
At the heart of the device, however, the channels would be lined with a catalyst that reacted with the electrolyte and also acted as an electrode.
The CO2 reduction takes place on a metal catalyst at the opposite side of nitride semiconductor photo-electrode.(See Fig. 1) The metal catalyst plays an important role in selecting and accelerating the reaction.
The ions pass through a charge-specific membrane and are adsorbed onto the surface of the electrode.

This layer acts as an electrode, so that the solar panel can be connected to a circuit.
The resin within the carbon layers is laced with lithium ions, so that each layer acts like an electrode, causing the positively charged lithium ions to collect in one layer when a voltage is applied, and a current to flow when the sandwich is placed in a circuit.
Another breakthrough is the transparent conductor made of a mixture of silver nanowire and titanium dioxide nanoparticles, which was able to replace the opaque metal electrode used in the past.
