چکیده
Developing ceramic coating with high hydrogen isotopes permeation resistance is an urgent task in many fields such as fusion reactor systems, storage/transportation, and fuel cell. In this work, a (TiVAlCrZr)O multi-component metal oxide glass (MCMOG) developed new type of barrier (HIPB), the diffusion behavior deuterium MCMOG studied for first time. Compared reduction factor (DPRF) 51 amorphous alumina (at 587 °C 0.65 µm), 29 nm dense has around 27 times enhancement DPRF 1420 at 550 °C. Based on first-principles calculations, we show that significantly suppressed MCMOGs attributed to sluggish arising from highly rugged energy landscape, which induced by diversity electronic band structures near Fermi level. addition, oxygen vacancies strongly affect PRF, where PRF fully oxidized layer (29 nm) 200 compared same thickness containing vacancies. Therefore, promising HIPB material.

Metal Permeation into Multi-layered Graphene Oxide
Understanding the chemical and physical properties of metal/graphene oxide (M/GO) interfaces is important when GO is used in electronic and electrochemical devices because the metal layer must be firmly attached to GO. Here, permeation of metal from the surface into GO paper bulk at the M/GO interface was observed at room temperature for metals such as Cu, Ag, Ni, Au, and Pt. Cu, Ag, and Ni qui...

متن کاملCalcium as the superior coating metal in functionalization of carbon fullerenes for high-capacity hydrogen storage.
We explore theoretically the feasibility of functionalizing carbon nanostructures for hydrogen storage, focusing on the coating of C60 fullerenes with light alkaline-earth metals. Our first-principles density functional theory studies show that both Ca and Sr can bind strongly to the C60 surface, and highly prefer monolayer coating, thereby explaining existing experimental observations. The str...

متن کاملBi-Directional Hydrogen Isotopes Permeation through the First Wall of a Magnetic Fusion Power Reactor
Plasma-driven permeation (PDP) and gas-driven permeation (GDP) through a first wall candidate material F82H have been investigated using a laboratory-scale steady state plasma facility. Experiments indicate that GDP may take place in the opposite direction of PDP, which then results in an unwanted increase in edge plasma density. A hydrogen flow from the plasma side to the gas side has also bee...
