Hydrogen-Bond-Mediated Solvation Reconfiguration Homogenizes Ion Flux for Stable Sodium Metal Batteries

Abstract Anode-free sodium metal batteries (AFSMBs) offer the promise of high energy density and low cost; however, dendrite growth caused by nonuniform Na deposition severely compromises the battery’s cycling stability. In this study, the Na+ solvation structure is dynamically o...

Touching Civilization: Enhancing Museum Experience for Visually Impaired Individuals through Spatiotemporal Guidance

Museum experiences remain largely inaccessible for blind and low-vision (BLV) individuals due to the visual-centric nature of traditional exhibitions. To address this gap, we present a VR-haptic museum system that combines digital 3D printing and virtual reality (VR) to deliver p...

An Edwards-type lower bound for the maximum k-cut of a connected graph

Let G be a finite simple connected graph with n vertices and m edges, and let f_k(G) denote the maximum number of bichromatic edges over all k-colorings of G. We prove that for every integer k ≥ 3, f_k(G) ≥ (k−1)m/k + (n−1)/k. Equivalently, the minimum number es_k(G) of edges who...

Radical-mediated synergistic remediation of crude oil contamination by nutrient-enriched indigenous microbial consortium from multiple culture media

To improve the low remediation efficiency of single microbial strains for crude oil-contaminated wastewater, indigenous microbial consortium was enriched using four media (TSB, PDB, YPD, and CPD). A ternary system integrating microbes, surfactants, and chemical oxidation was cons...

An investigation into LLMs’ abilities in discerning between true and false information

Large language models (LLMs) may judge whether information appears credible without necessarily establishing whether it corresponds to external facts. This study investigates this distinction by operationally separating Semantic Truth (ST), defined as the correspondence of textua...

Exploring the complexity of students’ inconsistent relational understanding of the equal sign

Abstract Students’ understanding of the equal sign is a well-researched topic. Recently, some new insights come to emerge. One is the phenomenon of students holding simultaneous operational and relational understanding (SOR). Researcher called for more investigation to this pheno...

Teacher Caring Behaviour and Junior High School Students' Learning Engagement in Physical Education: The Mediating Roles of Psychological Capital and Learning Motivation

ABSTRACT Background Physical activity has been shown to benefit students' academic achievement and engagement, yet the mechanisms remain unknown. In the present study, we aimed to examine the relationship between teacher caring behaviour and learning engagement among junior high...
