He was puzzled by the changes in the nanotubes»
electrical resistance when he turned the gauge on and off.
They found that certain metals completely lose
their electrical resistance when cooled to within a few degrees of absolute zero.
Not exact matches
Superconductors are materials that,
when chilled, allow
electrical current to flow freely, with zero
resistance.
A compound of hydrogen and sulfur,
when crushed at more than a million times Earth's standard atmospheric pressure, appears to whisk
electrical current along without
resistance at temperatures up to 203 kelvins.
When a user bends their fingers or thumb, the sensors stretch, and their
electrical resistance goes up.
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.
Some materials,
when cooled to temperatures near absolute zero, reach zero
electrical resistance.
They found that
when a negative
electrical potential is applied to skin on various parts of the arm, creating a current, that stretch of skin exhibits a low
resistance to a subsequent current flowing through the skin.
When superconducting materials are cooled, they can carry a current with zero
electrical resistance without losing any energy.
When the ions scatter electrons, it causes
electrical resistance in metals.
Recent research has shown that in two - dimensional systems, including semiconductors,
electrical resistance decreases and can reach almost zero
when they are subjected to magnetic and microwave influence.
These perovskites display what is called colossal magnetoresistance: their
electrical resistance changes dramatically
when exposed to a magnetic field, which makes them ideal for high - capacity data storage.
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.
Leading - edge research by a team of SUNY College of Nanoscale Science and Engineering (CNSE) scientists has been published in ACS Nano after the scientists evaluated ultrathin indium (III) selenide (In2Se3) nanosheets and discovered that their
electrical resistance drops significantly
when exposed to light.
Also, some of the energy used to overcome inertia and accelerate the vehicle — normally lost
when the vehicle is slowed, to aerodynamic forces and rolling
resistance as well to the mechanical brakes (as heat)-- may be recaptured as
electrical energy if regenerative braking is available (see the discussion of hybrid electric drive trains).
