source:miningResearchers at CERN’s Neutron Time-of-Flight facility (n_TOF) collaboration are investigating how cerium is produced in stars.Cerium is a rare earth metal that is used in some types of lightbulbs, flat-screen TVs and biomedical applications. While the element is rare in our planet’s crust, it is slightly more abundant in the universe.“The measurement we carried out enabled us to identify nuclear resonances never observed before in the energy range involved in the production of cerium in stars,” Simone Amaducci, first author of the paper that describes the findings, said in a media...

source:TechxploreTwo-dimensional (2D) superconducting materials have been found to be promising for the development of miniaturized optoelectronic devices. To perform well while consuming less energy, however, these smaller devices require a higher gate capacitance (i.e., gates that can store more electrical charge in proportion to the voltage applied).One approach to boost gate capacitance without decreasing the thickness of gate insulators or gate dielectrics entails the use of insulating materials with a high dielectric constant (κ), such as hafnium oxide (HfO2). While this could be an adva...

source:phys.orgResearchers at Columbia University have successfully synthesized the first 2D heavy fermion material. They introduce the new material, a layered intermetallic crystal composed of cerium, silicon, and iodine (CeSiI), in a research article published in Nature.Heavy fermion compounds are a class of materials with electrons that are up to 1,000 times heavier than usual. In these materials, electrons get tangled up with magnetic spins that slow them down and increase their effective mass. Such interactions are thought to play important roles in a number of enigmatic quantum phenomena...
