Climate change heightens global warming and brings about impending risks for both human society natural systems. is the greatest threat modern humans have ever faced. Pollutant discharges involve atmosphere result in challenge of that must be solved before it results irreversible damage. Current common threats crises need actions among all us: every continent, country, community, citizen. The e...

Bi-2212 is the only high-field, high-temperature superconductor (HTS) capable of reaching a critical current density $J_{\text{c}}$(16 T, 4.2 K) 6500 $\mathrm{A\cdot mm^{-2}}$ in highly desirable round wire (RW) form. However, state-of-the-art conductors still have ($J_{\text{c}}$) to depairing ($J_{\text{d}}$) ratio around 20 30 times lower than that $\mathrm{Nb-Ti}$ or REBCO. Previously, we s...
