Sentences with phrase «from electrical resistance»

Using electrically powered heat pumps to heat the water, rather than using the simpler but more direct heating effect from electrical resistance could increase the amount of heat per kWh of electricity up to three-fold.

Not exact matches

When Joachim and Gimzewski moved the STM tip down, slightly flattening their buckyball, the molecule's electrical resistance dropped 100-fold, allowing the current to flow more easily from the STM tip to the metal surface.

Countries, therefore, need to maintain good standards for measuring everything from length, weight, volume and temperature to force, hardness, electrical resistance, voltage, and the intensity of light.

«We've proved that generating entanglement between photons emitted from an LED can be achieved by adding another peculiar physical effect of superconductivity — a resistance - free electrical current in certain materials at low temperatures.»

Copper's rippled surface could add to the electrical resistance of nanowires made from the metal.

The whole accelerator is cooled to just 2 kelvins above absolute zero; the frigid temperature keeps the material's electrical resistance down and prevents energy from escaping.

A new study from the Cava lab has revealed a unifying connection between seemingly unrelated materials that exhibit extreme magnetoresistance, the ability of some materials to drastically change their electrical resistance in response to a magnetic field, a property that could be useful in magnetic memory applications.

The researchers found that migration of oxygen ions away from the contact area results in an abrupt change in the oxide lattice structure and an increase of electrical resistance.

Sir Andre Geim said: «We know from school that additional disorder always creates extra electrical resistance.

From the macroscopic standpoint, superconductivity is a property of certain materials that, when cooled below a given temperature, conduct electricity without any energy loss — i.e., with zero electrical resistance.

But increased electrical resistance is no substitute for genuine feedback and the MINI's Sport mode robs it of what information is coming back to the driver from the front wheels.

She runs electrical resistances or sources of heat through the materials she uses, creating delicate and ephemeral physical reactions, revealing all that which in daily life is hidden from view and beyond our comprehension.

Alice Miceli will show photographs from her new series on minefields; Daniel Steegmann Mangrané will make an intervention inspired in the museum's architecture, with which the audience can interact; Thiago Martins de Melo will exhibit his already famous paintings with intense figuration and a huge sculpture; and Wagner Malta Tavares will present a video and an installation with electrical resistances.
