“Silver is the best conductor of electricity because it contains a higher number of movable atoms (free electrons). For a material to be a good conductor, the electricity passed through it must be able to move the electrons; the more free electrons in a metal, the greater its conductivity....

To test a conductor with superconductive material which is in the superconducting state, the conductor is led through an external magnetic field which comprises at least two magnetic field regions spatially separated from each other and arranged one behind the other in the lengthwise direction of the...
Ruthenium: Another type of metal found in the platinum group, ruthenium is an extremely hard material with a lustrous gray appearance. Because of its density, ruthenium works well for metal finishing applications that require additional wear resistance, especially when alloyed with platinum or palladium...
The light guide device has a light conductor portion (16) made of translucent material (17) and a light source under the light conductor portion. The light conductor portion comprises translucent material, so that the light-changing material (18) is added to the change light from the light so...
Abrasion— the materials used in the production of torsion-resistant cables should be low in abrasion in order to provide the best results during friction and wear tests on the jacket material compounds. Oil— another aging factor is contamination with oils, which impair the service life ...
