Sentences with phrase «applying electric voltage»

This layer resides between two electrodes that can reverse the direction of its polarization — the alignment of positive and negative charges used to represent «0» and «1» in binary computing — by applying electric voltage to it.

They then added a layer of graphene in order to apply an electric voltage with which the density of electrons in the material could be controlled.

The nanowires are too small to scatter light on their own so the window is clear, but apply an electric voltage and that's when the magic happens.

Not exact matches

By applying a voltage across a carbon nanotube — a rolled - up sheet of carbon atoms — the team can generate a powerful electric field.

When voltage is applied to the capacitor, electric charges of equal magnitude, but opposite polarity, build up on each plate.

The same approach has been applied to the fuel cell, where a new converter triples system voltage from the cell to the electric motor, saving weight, space and cost.

One major problem, however, has been that when an electric voltage is applied across the film, DNA tends to move through the nanopore too quickly to read off all the bases in sequence.

When electric voltage is applied, they produce photons.

A high voltage is then applied across the gap, and the resulting electric fields convert the area between the electrode and the skin into non-thermal plasma.

Instead of transmitting electric current without any loss of power, as superconductors do, superinsulators completely shut off the flow of charges under an applied voltage.

When a voltage is applied to a so - called piezoelectric crystal, atoms in the crystal lattice stretch, like an accordion, along the direction of the applied electric field.

Electrical conductivity, a measure of how strongly a given material conducts the flow of electric current, is generally understood in terms of Ohm's law, which states that the conductivity is independent of the magnitude of an applied electric field, i.e. the voltage per metre.

Vernet says the electric wind is created by plasma actuators, devices that apply a high voltage between two electrodes.

The device also regulates electric current based on the history of voltages that have been applied to it, which is where the processing comes in.

Their goal was to apply a small amount of voltage to create an electric field and control the 2 - D compound's magnetism, giving them the ability to switch it on and off.

Dielectrophoresis (DEP) is a scalable technique to electronically trap and manipulate biological cells, biomolecules and nanoparticles using electric field gradients that can be generated by applying a voltage bias between two electrodes.

In certain materials, piezoelectrics, which expand or contract when applying a voltage, SAWs can be generated through oscillating electric fields.

Electric power generated in overrun and when applying the brakes on BMW ActiveHybrid 7 in a neutral process without any additional consumption of fuel is fed into the car's two on - board networks: BMW ActiveHybrid 7 features both a conventional 12 - volt on - board network fed by an AGM (absorbent glass mat) battery and a high - voltage battery featuring lithium - ion technology and operating at 120 V.

In overrun and when applying the brakes, the electric drive systems acts as a generator developing electric power fed into the high - voltage battery.

The spheres had hemispheres of two contrasting colors that would rotate to present one colored side to the viewer when voltage was applied to the sheet, thus displaying on screen an image or text that would stay there until the next electric charge.

The matrix is initialized and refreshed by applying voltage to all conductors of the array of FETs simultaneously, thus using the plate having the FETs as one of the two electrodes for impressing an electric field over the gyricon medium.
