31. An ideal, pure LC circuit exists only in the domain of superconductivity . 32. L�ders also mathematically investigated the quantum mechanical measurement process and worked on superconductivity . 33. The company's products also include superconductivity cables. 34. His work has helped to demonstrate that quantum spin fluctuations underlie exotic superconductivity . 35. In some formulations, large currents destroyed superconductivity . 36. The panel is also examining at least one superconductivity article in the journal Science. 37. This mixture substantially raises the temperature at which carbon-60 can achieve superconductivity . 38. Superconductivity is a phenomenon of exactly zero perfect conductivity " in classical physics.39. At low temperature fermions show superfluidity for uncharged particles and superconductivity for charged particles. 40. Perhaps the most famous is the Higgs boson of the BCS theories of superconductivity .
