source:Bayreuth UniversityResearchers at the Universities of Bayreuth and Linköping have produced two surprising compounds of nitrogen and the rare earth metal yttrium under very high pressure. The new polynitrides contain ring- and spiral-shaped crystal structures of nitrogen that have never before been observed in experiments or predicted in theoretical calculations. They look similar to widespread structures of carbon compounds. The high-pressure syntheses described in the journal Angewandte Chemie show that the diversity of possible nitrogen compounds and their structures is far great...

source:energyindustryreviewOne of the most amazing phenomena of nature is the manifestation of magnetism in some materials. Permanent magnets are known since ancient times. Before the great discoveries in the field of electricity, permanent magnets were actively used by physicians. Over time, people learned to create artificial magnets by placing iron alloy products in magnetic fields. Permanent magnets are frequently used in industry, in various fields, such as electrical engineering, computer technologies, transportation, navigation, medicine, biology, astronomy etc. The main application of ...

Source:DOE/SLAC National Accelerator LaboratoryA new study shows that nickel oxide superconductors, which conduct electricity with no loss at higher temperatures than conventional superconductors do, contain a type of quantum matter called charge density waves, or CDWs, that can accompany superconductivity.The presence of CDWs shows that these recently discovered materials, also known as nickelates, are capable of forming correlated states -- 'electron soups' that can host a variety of quantum phases, including superconductivity, researchers from the Department of Energy's SLAC Nat...
