Superconductivity was achieved at a record high temperature of minus-23 degrees Celsius (minus-9 degrees Fahrenheit)—a jump of about 50 degrees compared to the previous confirmed record. This was done at high pressures that were 1.5 million times more than sea level atmosphere. Researchers at the Max Planck Institute for Chemistry in Germany teamed up with …
A Columbia University-led team has developed a new method to finely tune adjacent layers of graphene—lacy, honeycomb-like sheets of carbon atoms—to induce superconductivity. Above – Applying pressure to twisted bilayer graphene transforms the material from a metal to a superconductor.

Calculations confirm the room-temperature superconductivity found by other authors, and show that it results from a strong e-ph interaction which is rather uniformly spread over electronic and vibrational states of both hydrogen and yttrium sublattices. Under high pressure there should be room temperature superconducting materials that are sodalite-like yttrium hydride clathrates. Arxiv – Superconductivity in …
It has been over 30 years since the discovery of the first high-temperature superconductor. The first high-temperature superconductor was 30 degrees about absolute zero. There was a flurry of work and the critical temperature reached -135 Celsius (138 Kelvin). The progress on improving the temperature at which the materials could work stalled for decades. There …
The European EcoSwing project swapped a compact and lightweight electric superconducting generator for a conventional generator in a 3.6 Megawatt wind turbine. The new generator is 4 meters in diameter, 1.5 meters smaller than a conventional one. It sits inside an 88 meter tall 3.6MW turbine in Thyboron, Denmark. The magnets made from a composite …
Chinese scientists plan to build the world’s most powerful electron collider by 2030, a project that will cost 35 billion yuan ($5.05 billion). Above – A sketch of the future Circular Electron Positron Collider.

Scientists at HZB have found evidence that double layers of graphene have a property that may let them conduct current completely without resistance. They probed the bandstructure at BESSY II with extremely high resolution ARPES and could identify a flat area at a surprising location. Above – The data show that In the case of …
Dutch researchers have successfully developed nanowires allowing individual electrons to be captured by a ‘quantum dot’ on which superconductivity can take place. These nanowires could make powerful quantum computers. The combination of a quantum dot and superconductivity makes it possible to create ‘Majorana fermions’, exotic particles that are their own antiparticle and which are regarded …
The Indian chemists who posted an Arxiv paper that nanostructured silver and gold are room temperature superconductors are well-regarded chemical physicists from the Indian Institute of Science in Bangalore, India. The researchers are not sharing their samples or their data. They are having their results validated by independent experts in the respective research fields. The …
The Lockheed Compact Reactor was kicked off with huge promises a few years ago and their patent based upon those promises has publicized again. Journalists and publications who do not follow nuclear fusion in detail missed the technical revisions in 2015 and 2017 that downgraded what Lockheed in 2014 had hoped and publicized by 100 …
Researchers created a “superlattice” of two graphene sheets stacked together — not precisely on top of each other, but rotated ever so slightly, at a “magic angle” of 1.1 degrees. The hexagonal honeycomb pattern is offset slightly, creating a precise moiré configuration that is predicted to induce strange, “strongly correlated interactions” between the electrons in …
