Superconductor 101 · Part 1
What Is a High-Temperature Superconductor?
A plain-English introduction to superconductivity: zero resistance, the critical temperature, and why liquid nitrogen changed everything.
Superconductor 101 · Part 2
REBCO, BSCCO, MgB₂: A Guide to Superconductor Chemistries
The main superconducting materials compared: NbTi, Nb₃Sn, BSCCO, REBCO and MgB₂. What they are, where each one works best, and how to read the Chemistry column in our tracker.
Superconductor 101 · Part 3
Inside a Superconducting Power Cable: Cryostat, Vacuum and Cooling
How a superconducting cable is built, layer by layer: HTS tapes, dielectric insulation, the vacuum-insulated cryostat, and the liquid-nitrogen cooling loop that keeps it all at −200 °C.
Superconductor 101 · Part 4
How REBCO Superconductor Tape Is Made (and Why It's Expensive)
REBCO tape is a kilometre-long feat of nanotechnology: a ceramic film grown on a steel ribbon with near-perfect crystal alignment. How coated conductor is manufactured and what drives the cost.
