Sentences with phrase «as the electrodes formed»

Not exact matches

Having the electrode in the form of tiny suspended particles instead of consolidated slabs greatly reduces the path length for charged particles as they move through the material — a property known as «tortuosity.»

The investigators used a multistep, yet simple, process to convert tree leaves into a form that could be incorporated into electrodes as active materials.

When the laser pulse has ionized the air, a current begins to pass between the electrodes and, as a result, the physicists are able to assess the appearance of the plasma clusters formed under the influence of the light that has formed into filaments.

In a real battery, thousands of these particles form an electrode, and positively charged lithium ions embed in the electrode as the battery charges.

As a first test, the researchers implanted electrodes into the brains of females to identify the circuitry activated when they naturally formed a pair bond and mated.

Laid down in thin films, randomly oriented carbon nanotubes form conductive networks that can serve as electrodes; patterned and layered films can function as sensors or transistors.

In this case, the array of sensors was formed of 21 ion - selective electrodes, including some with response to cations (ammonium, sodium), others with response to anions (nitrate, chloride, etc.), as well as electrodes with generic (unspecified) response to the varieties considered.

Strontium cobaltites are just one example of a class of materials known as transition metal oxides, which is considered promising for a variety of applications including electrodes in fuel cells, membranes that allow oxygen to pass through for gas separation, and electronic devices such as memristors — a form of nonvolatile, ultrafast, and energy - efficient memory device.

If the researchers can use multiple diamond tips in different shapes and further control the process, «one can envision forming a predesigned ribbon network ready to serve as electrodes in a specific circuitry of a future device,» he says.

This complex layer quickly forms from the decomposition products in the battery's electrolyte, the substance in batteries that acts as a medium to conduct lithium ions between electrodes.

Led by Prof Coleman, in collaboration with the groups of Prof Georg Duesberg (AMBER) and Prof. Laurens Siebbeles (TU Delft, Netherlands), the team used standard printing techniques to combine graphene nanosheets as the electrodes with two other nanomaterials, tungsten diselenide and boron nitride as the channel and separator (two important parts of a transistor) to form an all - printed, all - nanosheet, working transistor.
