Pt‐Mediated Co‐Adsorption of Hydroxyl and Nitrogen‐Heterocyclic Species Over Cu/CuO Heterostructure Enhances Coupled Azotriazole Electrosynthesis and Dual‐Electrode Hydrogen Production

ABSTRACT Electrocatalytic N─N oxidative coupling (OC) offers an eco‐friendly approach to produce value‐added azo materials, but suffers from sluggish kinetics and limited Faradaic efficiency (FE). The key fundamental issue is unfavorable competitive adsorption of hydroxyl groups...

Reference‐Dependent Preferences and Sentiment‐Driven Asset Prices

ABSTRACT This paper studies asset pricing under expectations‐based reference‐dependent preferences in a general equilibrium framework. We show that reference‐dependent preferences can generate self‐fulfilling risk panics, producing sentiment‐driven asset price fluctuations throug...

When Papers Stop Scaling: The Knowledge Abundance Paradox and the Institutional Economics of Scientific Coordination

Artificial intelligence can lower the cost of producing plausible research outputs without proportionally lowering the cost of verification and accumulation. This position paper defines the Knowledge Abundance Paradox, develops a quality-adjusted lifecycle framework for comparing...

Research on gambling and gambling harm in Aotearoa New Zealand: a scoping review

Gambling harm is a significant public health issue made more urgent by the rapid growth of online gambling. In Aotearoa New Zealand, gambling access expanded following the introduction of gaming machines in the 1990s and is expected to expand again with the regulation of online c...

Against Political Polarization: A Unified Framework for Tracing Evolving Political Ideologies on Social Media

The rapid growth of social media has greatly influenced political discourse, highlighting the need to understand individual political ideologies and their temporal dynamics. This task faces challenges such as data scarcity, abundant non-political content, costly and bias-prone ma...

Multi-objective and cross-scale inverse design of temperature-control materials via physics-constrained machine learning

Abstract Temperature-control materials, notably composite phase-change materials (CPCMs), show great potential for the thermal management of next-generation power electronics. However, the synergistic optimization of multiple performance metrics still relies heavily on Edisonian...

Distraction Across Languages: The Impact of Background Music Lyrics on First‐ and Second‐Language Reading Comprehension

ABSTRACT Background music with lyrics can be a prevalent distraction in environments where people study or read while music plays. However, such effects on reading comprehension across different language contexts remain insufficiently investigated. Guided by the duplex‐mechanism...

Efficient Acidic CO 2 Reduction via Local Strain Engineering of Nickel Single‐Atom Catalysts

ABSTRACT Acidic CO 2 reduction reaction (CO 2 RR) enhances carbon efficiency and electrolyzer stability. Although nickel single‐atom catalysts (Ni‐SACs) effectively convert CO 2 into CO in neutral/alkaline conditions, their performance in acid is hindered by the competing hydroge...

Surface-Charge-Regulated MoS2 Membrane for Induced Agglomeration and Efficient Removal of Nanopollutants

Abstract Conventional membranes for nanopollutant removal are constrained by the permeability–selectivity trade-off inherent in size-exclusion mechanisms. Here, we report a surface-charge-regulated MoS2 membrane engineered by anchoring copper nanoparticles and quaternary ammonium...

Energy-Time-based Docking-Return Path Planning for Cooperative UAV–UGV Systems in GPS-Denied Environments

Unmanned Aerial Vehicles (UAVs) and Unmanned Ground Vehicles (UGVs) offer complementary capabilities for long-duration autonomous missions, where UAV recovery by a ground platform can significantly reduce aerial energy consumption. In practical GPS-denied environments, however, s...

Harnessing macrophage signaling pathways and scalable engineering for next-generation immunotherapies

Macrophages have emerged as promising candidates for cell-based immunotherapies due to their intrinsic plasticity, tissue-infiltrating capabilities, and central roles in orchestrating immune responses. Their phenotypic and functional diversity within tissues and the tumor microen...

Shape-Induced d-BandCenter Optimization ofPdBiNi Nanocubes for Exclusive Oxidation of Glycerol into C3 Products

Abstract Electrocatalytic oxidation of glycerol toward high-value C3 products on Pd-based catalysts presents a promising strategy for upgrading and converting glycerol. However, C3 intermediates often adsorb too tightly on Pd-based catalyst surfaces during glycerol oxidation, lea...

A multicohort, biomarker-driven phase 2 trial of personalized total neoadjuvant therapy with targeted agents for high-risk rectal cancer (The TRAINER study)

This multicohort, single-center, phase II trial explored the efficacy and safety of a biomarker-driven total neoadjuvant therapy (TNT) regimen in high-risk locally advanced rectal cancer (LARC) patients. The regimen included induction chemotherapy (4 cycles of mFOLFOX6) with targ...

Phased fuel transitions for decarbonizing the Asia–Europe Green Shipping Corridor

Shipping remains almost entirely reliant on fossil fuels, and identifying viable fuel transition pathways under evolving regulations is a key challenge. A study now evaluates 13 alternative marine fuels for the Asia–Europe corridor, revealing phased transitions shaped by policy d...

Valorization of Wastewater Phosphorus into Battery-Grade FePO4 via In-Situ Anodic Precipitation in an Electro-Driven Membrane System

Abstract The exponential growth of the new energy vehicle market has precipitated an urgent demand for sustainable lithium iron phosphate (LiFePO4) precursors. While recovering iron phosphate (FePO4) from phosphorus-rich wastewater presents a viable supply chain solution, convent...

Research engagement profiles among Chinese undergraduate and postgraduate students

Research engagement is increasingly recognized as an important component of student development in higher education, particularly in medical and health sciences disciplines, but it is often measured through isolated activities or publication status alone. This study examined rese...

The new first listener: Daydreaming styles and self‐compassion predict adolescent disclosure to AI , differently in ADHD

AI chatbots are rapidly becoming a common place where adolescents first disclose personal experiences, because the interaction is private, always available, and often feels lower-stakes than telling another person. Recent U.S. evidence suggests that about one in eight adolescents...

EngageCue: Enabling Balanced Engagement in Face-to-Face Group Collaboration via AI Cues Through Smart Glasses

In face-to-face group collaboration, uneven engagement often undermines efficiency and interaction quality. Although AI and wearable devices are increasingly applied to support collaboration, existing approaches largely remain confined to online or screen-based environments, leav...

Accuracy assessment of Chinese large language models in psoriasis management: a multicenter expert evaluation study

Psoriasis patients in China face severe barriers to disease knowledge acquisition and limited access to medical resources, creating an urgent demand for reliable, evidence-based patient education tools. This multicenter expert evaluation study aimed to systematically assess the q...

Developing Structurally Uniform Nitrogenous Model Systems to Interrogate the Metal-Free Oxygen Reduction Reaction

Abstract Oxygen reduction reaction (ORR) is a kinetically sluggish reaction under uncatalyzed conditions. Numerous studies have revealed that mixtures of N-doped moieties in graphene improve ORR activity and selectivity. However, due to the surface heterogeneity of N-doped carbon...
