Superconducting (Li1-xFex)OHFe1-ySe films are attractive for both the basic research and practical application. However, conventional vapor deposition techniques not applicable in synthesizing of such a complex system. So no intrinsic charge transport measurements on available so far to reveal nature carriers, which is fundamental understanding iron-based superconductivity mechanism. Herein we report soft chemical film technique (matrix-assisted hydrothermal epitaxial growth), by have...
Fission power is a promising technology, and it has been proposed for several future space uses. It being considered high-power missions whose goal to explore the solar system even beyond. Space fission made great progress when NASA’s 1 kWe Kilowatt Reactor Using Stirling TechnologY (KRUSTY) prototype completed full scale nuclear test in 2018. Its success stimulated new round of research competition among major countries. This article reviews development Kilopower reactor KRUSTY design....
By carrying out dispersion-inclusive density-functional theory computations, we propose a novel type of molecular memory based on the physisorbed and chemisorbed states layer aromatic molecules metal surfaces. As exemplified by hexachlorobenzene (C6Cl6) Pt(111), find that self-assembled monolayer exhibits an intriguing bistable behavior: can stay stable in either physiosorbed state ("1") or ("0"), along with moderate switching barrier. Correspondingly, our transport computations...
Abstract Cosmic ray muon radiography is a new imaging technique that being used to investigate the density structure of large objects and shallow crust.
