Physicists discover a copper-free high-temperature superconducting oxide (phys.org)
Professor Ariando and Dr. Stephen Lin Er Chow from the National University of Singapore (NUS) Department of Physics have designed and synthesized a groundbreaking new material—a copper-free superconducting oxide—capable of superconducting at approximately 40 Kelvin (K), or about minus 233°C, under ambient pressure.
Nickel superconductor works above -233°C threshold at normal pressure (phys.org)
A team of engineers and physicists at Southern University of Science and Technology, in China, has created a nickel-based material that behaves as a superconductor above the -233°C (40 K) threshold under ambient pressure.
Room-temperature superconductors: Fundamental constants suggest they could exist (phys.org)
In a new development that could help redefine the future of technology, a team of physicists has uncovered a fundamental insight into the upper limit of superconducting temperature.
Magnetic field sorting of superconducting graphite particles with Tc>400K (2024) (arxiv.org)
It has been claimed that graphite hosts superconductivity at room temperature, although all efforts to isolate it have been vain. Here we report a separation method that uses magnetic field gradients to sort the superconducting from normal grains out of industrial graphite powders.
The superconductivity of layered graphene (newscientist.com)
Why do cold thin sheets of carbon offer no resistance to electric currents? Two experiments are bringing us closer to an answer – and maybe even to practical room-temperature superconductors.
Exotic new superconductors delight and confound (quantamagazine.org)
This year, superconductivity — the flow of electric current with zero resistance — was discovered in three distinct materials. Two instances stretch the textbook understanding of the phenomenon. The third shreds it completely. “It’s an extremely unusual form of superconductivity that a lot of people would have said is not possible,” said Ashvin Vishwanath, a physicist at Harvard University who was not involved in the discoveries.

Revealing the superconducting limit of twisted bilayer graphene (phys.org)
Graphene is a simple material containing only a single layer of carbon atoms, but when two sheets of it are stacked together and offset at a slight angle, this twisted bilayer material produces numerous intriguing effects, notably superconductivity.
