Pressure unlocks 3D superconductivity in tantalum disulfide at triple the temperature
Superconductors have long been considered a promising technology for the energy systems of the future. They can conduct electricity without resistance, thus eliminating both conduction losses and waste heat. Up to now, however, superconductors have only been applied in special ca
Carbon–bismuth bonds reveal that relativity blurs the textbook line between sigma and pi b
Brown University chemists have provided direct evidence that upends the textbook explanation of how triple chemical bonds work in heavy elements. In a study published in Science, the researchers show evidence that when atomic nuclei are sufficiently heavy, the principles describe
Visible light triggers three-step cascade to make 3D drug-like molecules
A team led by chemist Frank Glorius, a professor at the Institute of Organic Chemistry at the University of Münster, has developed a new light-driven reaction sequence. In this triple catalysis, one reaction step triggers the next like three dominoes in a row, toppling one after
