SEI’s bismuth-based superconducting material is made of bismuth – strontium – calcium – copper – oxygen (Bi-Sr-Ca-Cu-O). Superconductors have zero resistance to the flow of electricity, so a vehicle ...

van der Marel and colleagues studied a high-temperature superconductor made of bismuth, strontium, calcium, copper and oxygen – known as Bi-2212 – which has a superconducting transition temperature of ...

Using an air-free, cryogenic crystal manipulation method in ultrapure argon, Zhao engineered a clean interface between two extremely thin layers of the cuprate bismuth strontium calcium copper ...

Variation of the critical current density of Bi-2223 (a bismuth strontium calcium copper oxide) with graphene addition. (Top) Schematic diagram demonstrating the parallel alignment of the BSCCO grain ...

This involves an oxide of bismuth, strontium, calcium and copper, known as BSCCO. A powdered form of this material is placed in a tube made of silver (pricey, but essential because of both its ...
