Abstract The safety of future fusion reactors is critically dependent on the tritium (T) retention in plasma-facing materials. Hydrogen isotope (HI) exchange offers a method to redistribute HIs within solid materials, presenting feasible approach for removing T from bulk materials and trapped by strong trapping sites. Nonetheless, unraveling intricate mechanism behind HI remains an urgent yet formidable challenge. This study undertakes comprehensive investigation into tungsten across...
MAX phase materials have attracted increased attention due to their unique combination of ceramic and metallic properties. In this study, the properties vacancies in Ti₃AlC₂ Ti₃SiC₂, which are two most widely studied phases, were investigated using first-principles calculations. Our calculations indicate that stabilities Ti₃SiC₂ differ greatly from those previously reported for Cr₂AlC. The order formation energies is VTi(a) > VTi(b) VC VA both Ti₃AlC₂. Although diffusion barriers similar...
Metallic multilayered nanofilms have been extensively studied owing to their unique physical properties and applications. However, studies on the thermal conductivity electrical resistivity of metallic nanofilms, as important properties, are seldom reported. In this work, Cu/W with periodic thickness varying from 6 150 nm were deposited by magnetron sputtering. The resistivities increase decrease thickness, especially when is smaller than 37 nm. fit well Fuchs-Sondheimer Mayadas-Shatzkes...
Tuning the catalytic pathways of atomically dispersed single‐atom catalysts (SAC) has emerged as an effective strategy to optimize their overall activity. Herein, we present Ru1@m‐tube, a hollow carbon nitride‐supported Ru SAC, coated with eutectic galinstan (GaInSn), model catalyst, demonstrate performance inversion in vanillin conversion. Vanillin, biomass‐derived compound industrial relevance, presents challenges hydrogenation, making it ideal reaction test and compare catalyst's...
As impurities are virtually impossible to exclude from Pu oxides in realistic environments, understanding the roles of is crucial for applications and designs oxides. Here we perform a systematic first-principles DFT + U calculation find trends transition-metal (TM) behaviors PuO2 terms energetics, atomic properties, oxidation states, electronic structures. The results show that group IV-B elements Ti, Zr, Hf energetically electronically favorable render possibilities forming Pu-TM-O ternary...
Nanochannel tungsten (W) film is a promising candidate as an alternative to bulk W for use in fusion applications. In previous work it has been shown have good radiation resistance under helium (He) irradiation. To further understand the influence of irradiation-induced displacement cascade damage on retention behaviour environment, this work, nanochannel and were pre-irradiated by 800 keV Kr2+ ions fluence 2.6 × 1015 cm−2 subsequently irradiated 40 He+ 5 1017 cm−2. The ion pre-irradiation...
Multiple shock reverberation compression experiments are designed and performed to determine the equation of state neon ranging from initial dense gas up warm regime where pressure is about 40 MPa 120 GPa temperature 297 K above 20 000 K. The wide region experimental data used evaluate available theoretical models. It found that, for below $1.1\phantom{\rule{0.28em}{0ex}}{\mathrm{g}/\mathrm{cm}}^{3}$, within framework density functional theory molecular dynamics, a van der Waals correction...
Developing high-radiation-tolerant inert matrix fuel (IMF) with a long lifetime is important for advanced fission nuclear systems. In this work, we combined zirconia (ZrO2) magnesia (MgO) to form ultrafine-grained ZrO2-MgO composite ceramics. On the one hand, formation of phase interfaces can stabilize structure ZrO2 as well inhibiting excessive coarsening grains. other grain refinement ceramics increase defect sinks. Two kinds different sizes were prepared by spark plasma sintering (SPS),...
The effective one-component plasma (EOCP) model has provided an efficient approach to obtaining many important thermophysical parameters of hot dense matter [J. Cl\'erouin, et al., Phys. Rev. Lett. 116, 115003 (2016)]. In this paper, we perform extensive quantum molecular dynamics (QMD) simulations determine the equations state, ionic structures, and transport properties neon krypton within warm (WDM) regime where density ( $\ensuremath{\rho}$ ) is up 12 $\mathrm{g}/{\mathrm{cm}}^{3}$...
