Claims of Practical Room Temperature Superconductor

University of Rochester researchers claim they have created a superconducting material at both a temperature and pressure low enough for practical applications. Ten thousand atmospheres of pressure is still manageable. These pressure are used in chip manufacturing. NOTE: These researchers had issues proving a prior paper. They withheld data until they could get a patent. …

Possible Room Temperature Superconductor Under Diamond Anvil Pressure

Superconductivity in a photochemically transformed carbonaceous sulfur hydride system, starting from elemental precursors, with a maximum superconducting transition temperature of 287.7 ± 1.2 kelvin (about 15 degrees Celsius) achieved at 267 ± 10 gigapascals. The superconducting state is observed over a broad pressure range in the diamond anvil cell, from 140 to 275 gigapascals, with …

Progress to Practical Room Temperature Superconductors

Using extremely high pressures, experimentalists have created many superconducting hydride compounds including one—carbon sulfur hydride (CSH)—that appears to work at close to room temperature. Theorists have predicted other hydride compounds which could work at lower pressures. There is race to find versions stable at ambient pressure and room temperature. In 2004, Ashcroft suggested that adding …

Room Temperature Superconductor Under Diamond Anvil Pressures

University of Rochester researchers squeezed carbonaceous sulfur hydride in a diamond anvil and it superconducted at 15 degrees Celsius under 270 gigapascals of pressure. This is about 2.5 million times regular atmospheric pressure. The bottom of the Mariana Trench has 1071 times the pressure of regular atmosphere. The sample were between 25 and 35 microns. …

AI and Supercomputing For Better Superconductors

Argonne researchers use genetic algorithms to find better superconductors. Certain patterns of defects composed of metallic inclusions were found to maximize the critical current. researchers developed a computer algorithm that treated each defect like a biological gene. Different combinations of defects yielded superconductors able to carry different amounts of current. Once the algorithm identified a …

Superconductivity 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 level atmosphere. Researchers at the Max Planck Institute for Chemistry in Germany teamed up with …

High Temperature Superconductivity at 2 Million Time Pressure

Metallic, hydrogen-rich compounds become superconducting at very high pressures. Russell Hemley and his group at George Washington University measured significant drops in resistivity when the sample cooled below 260 K (minus 13 C, or 8 F) at 180-200 gigapascals of pressure, presenting evidence of superconductivity at near-room temperature. In subsequent experiments, the researchers saw the …

If These US Navy Patents are Made Then We Are in a Star Trek Technology World

Salvatore Cezar Pais is a US Navy researcher. Salvatore has three amazing patents that would be incredible breakthroughs in physics if they are true. The least extreme is a patent for Piezoelectricity-Induced Room Temperature Superconductor. The other two patents are gravity wave generator and inertial mass reduction. If these could be realized as technologies then …

Calculations 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 be room temperature superconducting materials that are sodalite-like yttrium hydride clathrates. Arxiv – Superconductivity in …

New Evidence of Superconductivity at Near Room Temperature and High Pressure

Researchers at the George Washington University have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity. The key to this discovery was creation of a metallic, hydrogen-rich compound at very high pressures: roughly 2 million atmospheres. The researchers used diamond anvil cells, devices used to create high …

Superconductors 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 progress on improving the temperature at which the materials could work stalled for decades. There …
