The elements hydrogen, carbon, nitrogen and oxygen are assumed to comprise the bulk of interiors ice giant planets Uranus, Neptune, sub-Neptune exoplanets. details their interior structures have remained largely unknown because it is not understood how compounds H2O, NH3 CH4 behave react once they been accreted exposed high pressures temperatures. Here we study thirteen H-C-N-O with ab initio computer simulations demonstrate that assume a superionic state at elevated temperatures, in which...
In the last decade, there has been great progress in predicting and synthesizing polyhydrides that exhibit superconductivity when squeezed. Dopants allow these compounds to become metals at pressures lower than those required metallize elemental hydrogen. Here, we show by combining fundamental planetary building blocks of molecular hydrogen ammonia, conventional superconducting can be formed high pressure. Through extensive theoretical calculations predict metallic metastable structures with...
The ice giant planets Uranus and Neptune are assumed to contain large amounts of planetary ices such as water, methane, ammonia. properties mixtures at the extreme pressures temperatures interiors not yet well understood. Ab initio computer simulations predicted that a number exhibit hydrogen superionic state doubly [DOI: 10.1038/s41467-023-42958-0]. Since latter has been generated with experiments, we outline here two possible pathways for reaching detecting dynamic compression experiments....
The past decade has witnessed great progress in predicting and synthesizing polyhydrides that exhibit superconductivity under pressure. Dopants allow these compounds to become metals at pressures lower than those required metallize elemental hydrogen. Here, we show by combining the fundamental planetary building blocks of molecular hydrogen ammonia, conventional superconducting can be formed high Through extensive theoretical calculations, predict metallic metastable structures with NHn (n =...
Hydrothermal circulation around magmatic intrusions affects hazards, critical metal deposition, and heat transfer, however it is often difficult to directly observe. We combine stable isotope thermochronologic measurements, hydrothermal modeling, forward thermal history modeling understand the short-lived system that developed Little Devils Postpile, a small-scale mafic intrusion in eastern Sierra Nevada Mountains of western North America. Bedrock samples collected transects orthogonal...
