Sentences with phrase «material at certain temperatures»

Nobody knows why, and we've heard theories from humidity to the friction coefficient of the material at certain temperatures and conditions, but the fact is a lot of glass - backed nexus 4 phones won't stay on it.

Instead, they measured significantly more heat than charge flowing through the material at certain temperatures.

Not exact matches

For example, when certain materials are cooled to frigid temperatures, electrons team up so they can flow uninhibited, without losing any energy at all — a phenomenon called superconductivity.

A growing class of materials possess «shape memory» — they hold one form at a certain temperature and transform into another shape when heated.

Certain combinations of elements, when heated and cooled to specific temperatures at specific rates, result in materials with unusual plasticity and strength.

At certain temperatures, they found that the combined material's stiffness was greater than the conventionally calculated maximum — greater even than if they had embedded the tin with diamond.

Superconductivity is based on the fact that in certain materials electrons can pair up which — at a higher temperature — would otherwise repel each other.

«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.»

Researchers have shown that certain superconductors — materials that carry electrical current with zero resistance at very low temperatures — can also carry currents of «spin».

One potential roadblock is the instability of certain materials at high temperatures.

Hideo Ohno, a materials scientist at Tohoku University in Japan, decided to tackle this problem by investigating certain semiconductors that become magnetic at temperatures around 25 K, or -248 °C.

Like astronomers tweaking images to gain a more detailed glimpse of distant stars, physicists at Brookhaven National Laboratory have found ways to sharpen images of the energy spectra in high - temperature superconductors â $» materials that carry electrical current effortlessly when cooled below a certain temperature.
