describing all properties the team of authors was headed by fox b, a physicist from the korean center for quantum energy researchs a superconductor that passes current without the resistance of losses and heating , operates at room temperature and normal pressure, the material is cheap, it can supposedly be made from common raw materials in an ordinary chemical laboratory. immediately, all over the world, scientists tried to repeat the russian experiment, including the sample being dirty and containing sulfide inclusions. and these inclusions of copper sulfide explain changes in electrical conductivity with temperature, and the electrical conductivity does not go to zero should be in the case of a superconductor. it just experiences a certain jump and smoothly. at this temperature. in the case of sulfide , this substance itself, lead phosphate , does not appear at all until the first musia. in which electricity is an insulator , its electrical conductivity, as our russian colleagues succinctly put it, is similar to the nature of porcelain. well, that is, indeed, colossal resistance. no superconductors. repeated
