where R is the electrical resistance, A is the cross-sectional area, and l is the length of the material Electrical conductivity gradually increases in ametallic conductoras the temperature is lowered. Below a critical temperature, resistance in superconductors drops to zero, such that an electrical...

Electrical conductivity occurs because of the ease with which electrons can be removed from atoms. All substances consist of atoms. In turn, all atoms consist of two main parts: a positively charged nucleus and one or more negatively charged electrons. An atom of iron, for example, consists ...
- 《Journal of the American Chemical Society》 被引量: 72发表: 2009年 Poly(heteroaromatic) block copolymers with electrical conductivity The present invention provides block copolymers containing at least one block of a poly(heteroaromatic) polymer and at least two blocks of a non-conjugated polymer...
Sensors: Sensors are devices that detect physical or chemical changes in their environment by using electrical signals. They often use dielectric materials as sensing elements or transducers that convert one form of energy into another. For example,piezoelectric sensorsuse crystals or ceramics that gener...
Conductivity measurements have been performed at 90–300°K on iron of high purity and dilute alloys of this metal with Mn, Ni or Si. For the elimination of the parasitic thermal losses in the heat-conductivity measurements a special method has been worked out. The validity of the Wiedemann-...
2.3 Physico-chemical analysis The temperature, potential of hydrogen (pH), and electrical conductivity (EC) of each groundwater sample were measured in-situ with the help of a digital thermometer, pH, and EC meter, respectively. The laboratory analysis of collected groundwater samples has been ca...
Electrical conductivityEnergy gapA broadly varied series of activated carbons (ACs) was prepared from vine shoots (VS) by the method of physical activation in air, CO2 and steam, and by the method of chemical activation with H3PO4, ZnCl2 and KOH aqueous solutions. Here, the temperature ...
