Pu-Doping-Induced Weberite-like Local Motifs and Enhanced Immobilization in Gd2Zr2O7 Pyrochlore: A DFT + U Study

Abstract This study employs density functional theory with the Hubbard U correction (DFT + U) method to investigate how Pu incorporation into distinct sites (Gd or Zr) in Gd2Zr2O7 governs locally weberite-like disorder and subsequently influences Pu immobilization behavior. We re...

Asymmetric Alkylation of α-Cyanoketimines with Alkyl Bromides Catalyzed by Bis-Cinchonium Salts

Abstract The SN2 reaction constitutes one of the most fundamental bond-forming transformations in organic chemistry, finding numerous synthetic applications across pharmaceutical, agrochemical, and materials science. However, the development of new catalysts for asymmetric SN2 re...

Artificial Neural Networks for RF Passive-Device Modeling and Design: A Review

Artificial neural networks (ANNs) offer efficient surrogates for radio-frequency (RF) passive-device modeling and design, but prediction accuracy alone does not establish their engineering reliability. This review examines four overlapping analytical perspectives: data generation...

Flood-Induced Scour Failure Mechanisms and Multi-Level Protection of Riverside Highway Embankments: A Physical Model Study

Scaled flume tests based on Froude similarity (λ = 1:50) were conducted to clarify the internal stress-field evolution and multi-level protection mechanisms during flood scour of riverside highway embankments. An 18-channel miniature earth-pressure system embedded along the slope...

The effect of pulsating liquid sodium coolant inlets on flow structures and thermal mixing in a T-junction

Mixing of two pipe streams at different temperatures features in the secondary circuit of compact sodium-cooled fast reactors. This study presents the numerical simulation of flow features and mixing characteristics in the T-junction with the inlets subjected to co-pulsating and...

Evaluating net energy value of fermented citrus pulp and its effects on performance and egg quality in laying hens

Two experiments were conducted to determine the apparent metabolisable energy (AME), nitrogen-corrected apparent metabolisable energy (AMEn), and net energy (NE) values of fermented citrus pulp (FCP) for layers and to evaluate its effects on performance and egg quality. In Experi...

Multi-omics elucidate octapeptin mechanisms in alleviating intestinal injury in mice challenged with ETEC K88 via modulated microbial and host pathways

K88 (ETEC K88) in mice. Octapeptin ameliorated intestinal injury by modulating gut microbiome-host interactions. When compared with ETEC K88 mice, octapeptin significantly attenuated growth retardation, systemic oxidative stress, pro-inflammatory cytokine elevation, and ileal mor...

Artificial intelligence cooperation and domestic absorptive capacity: evidence from ASEAN economies

Abstract Cross-border artificial intelligence (AI) cooperation is expanding, but evidence on its effect on domestic technological capability in recipient economies is scarce. Drawing on absorptive capacity theory, we create a composite AI absorptive capacity index for 10 Associat...

177Lu-Labeled Ectonucleotide Pyrophosphatase/Phosphodiesterase 3 Monoclonal Antibody-Targeted Therapy for Clear Cell Renal Cell Carcinoma

Abstract Clear cell renal cell carcinoma (ccRCC) remains a therapeutic challenge. Ectonucleotide pyrophosphatase/phosphodiesterase 3 (ENPP3) is highly expressed in ccRCC tissues and cell lines, representing a promising target. This study aimed to conjugate lutetium-177 (177Lu) to...

Biochar–Microbe Interactions for Co-Remediation of Heavy Metals and Pesticides in Soils: Mechanisms, Synergies, and a Translational Framework

The co-occurrence of heavy metals (HM) and pesticides (PS) in agricultural soils poses a complex remediation challenge that resists single-amendment strategies. Although biochar (BC) has been widely reported as an efficient adsorbent for specific contaminants, increasing evidence...

Low-Carbon Transition Performance of Cropland Use in the Principal Grain-Producing Counties of Sichuan Province: Spatiotemporal Evolution, Spatial Spillovers, and Driving Factors

The low-carbon transition of cropland use must reconcile emission reduction with food security in major grain-producing areas. Using panel data for 89 major grain-producing counties in Sichuan Province, China, from 2010 to 2022, this study measures the low-carbon transition perfo...

Effect of ZrO2 substitution for SiO2 on the structure and properties of high-alumina-silicate glasses

High-alumina-silicate glasses with ZrO 2 substitution for SiO 2 were prepared by a conventional melt-quenching method to investigate the effects of ZrO 2 substitution on the structure, thermal properties, optical transmittance, microhardness, and chemical strengthening behavior o...
