ABSTRACT Achieving efficient separation of thorium and uranium is one the main technical challenges for nuclear fuel cycle thorium‐based molten salt reactors. In this work, scalar relativistic density functional theory (DFT) calculations were adopted to deeply unravel complexation behaviors selectivity Th 4+ /UO 2 2+ with four amide ligands L A , B C D containing N ‐heterocycles. The analyses dihedral angle, bond length, WBIs, IGMH, ETS‐NOCV indicated that more likely coordinate in gas phase...
Unraveling uranium complexes has become a popular study topic in recent years to address the problem of spent fuel treatment. An important and promising investigation is enantiomer separation chiral organophosphorus pesticides (OPs) via uranyl‐containing receptors. Among them, malaoxon (MLX), as OP with high toxicity good selectivity, controversial because different differences caused by R S configurations target non‐target organisms. Therefore, it crucial explore effective methods for...
Abstract Development of shielding materials for 222 Rn and γ radiation has crucial implications ensuring the safety individuals. This paper reports synthesis modified graphene nanosheets (MGNPs) via reaction KH560 with (GNPs), while melt blending hot‐press molding technique were used to fabricate a multifunctional polymer composite material, MGNP/WB/PMMA (polymethyl methacrylate). Successful MGNP was confirmed by Fourier transform infrared spectroscopy, scanning electron microscope (SEM)...
The digitalization and intelligence of nuclear power plants (NPPs) enable neural networks to predict transient parameters, aiding operators in emergency responses. This paper addresses the limitations back propagation (BP) network, which can lead local optima reduced accuracy predicting by introducing Firefly Algorithm (FA) optimize BP creating FA–BP network. Using data from PCTRAN, a plant accident simulation software, study compares predictive performance network with conventional LSTM...
Abstract With the increasing complexity of radiation environments, development effective shielding materials against 222 Rn and gamma is critical for ensuring human health safety. This study utilized a two‐step hydrothermal method to synthesize Gd₂O(CO₃)₂@bismuth‐based metal–organic frameworks (Bi‐MOFs)/graphene nanoplatelets (GBG) composite fillers, followed by melt blending hot‐press molding develop GBG/polymethyl methacrylate (PMMA) composites aimed at radiation. The successful synthesis...
First-principles methods are employed to investigate the adsorption and diffusion of Co on Si(001). After determining surface subsurface binding sites, nudged elastic band calculations performed explore inward from into for It is found that atoms diffuse quickly surface, while slower. At low coverage, our predict will be mainly underneath Si layer, which in agreement with experimental results. The coefficients also calculated compared
First-principles methods are employed to determine how Si diffuses in the layered metal silicide $\mathrm{Er}{\mathrm{Si}}_{2\ensuremath{-}x}$. diffusion is found be extraordinarily anisotropic, with migration barrier associated diffusing across Er planes nearly four times larger than within planes. The activation energy for in-plane of decreases by 20% when $\mathrm{Er}{\mathrm{Si}}_{2\ensuremath{-}x}$ grown heteroepitaxially on Si(001), as a result epitaxial strain. This effect strain...
Novel group quantitative structure-property relationship (QSPR) models on the thermodynamic properties of PBXTHs were presented, by multiple linear regression (MLR) analysis method. Four studied: entropy (Sθ), standard enthalpy formation (ΔfHθ), Gibbs energy (ΔfGθ), and relative (ΔRGθ). The results formula indicate that calculated predicted data in this study are good agreement with those literature deviation is within experimental errors. To validate estimation reliability for internal...
Hoping resolve uranium release caused many harmful environmental impacts by genetic engineering bacteria, which is considered desirable and an innovative environmental-friendly water remediation strategy. Here, we report the great U deoxygenation potential of E. coli. DH5α W1 was introduced Dsr A gene sulfate-reducing bacteria to strengthen its performance for deoxygenating (VI) (IV) reducing it’s toxic. In static adsorption, will undergo a phenomenon immediately after super-adsorption...
Exploring highly active, durable, and low-cost hydrogen evolution reaction (HER) catalysts to replace platinum is beneficial for the rapid commercialization of proton exchange membrane water electrolysis. Herein, we develop an efficient catalyst featured with RuP nanoclusters encapsulated in N,P-codoped carbon (PA-RuP@NPC750) through phytic acid-assisted pyrolysis. Phytic acid coating cannot only control growth a cluster within subnanoscale (1.55 nm) during pyrolysis but also strengthen...
First-principles calculations are performed to explore the diffusion of excess Si vacancies in rare-earth silicide $\mathrm{Er}{\mathrm{Si}}_{2\ensuremath{-}x}$. Nudged elastic band show that diffuse quickly within planes via a site-exchange mechanism with neighboring atoms, barrier $0.67\phantom{\rule{0.3em}{0ex}}\mathrm{eV}$. The vacancy across Er is more difficult (the height nearly 4.4 times larger). This leads remarkable anisotropy these two directions. When...
