futureNew Superconducting Material Could Make Disruption Resistant Quantum Computers

In the new study, Yufan Li and colleagues found that a ring of β-Bi2Pd already naturally exists between two states in the absence of an external magnetic field. Current can inherently circulate both clockwise and counterclockwise, simultaneously, through a ring …

energySuperconductivity at Near Room Temperature Under Very High Pressure

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 …

grapheneTuning Graphene Superconductivity

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. …

physicsCalculations of Room Temperature Superconductors But Requiring High Pressure

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 …

energySuperconductors Are Near Room Temperature But UHV Lines are Better for the Grid

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 …

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 …

chinaChina plans particle collider five times larger than biggest

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. (Photo/Courtesy of Chinese Academy of Sciences …

grapheneBilayer Graphene on the way to becoming a superconductor

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 …

nanowireSuperconducting nanowires created that are promising for future quantum computers

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 …

physicsClaimed Room Temperature Superconductor awaits independent confirmation

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. …
