Nanowire-Threaded NiZn Layered Double Hydroxide Nanocage Heterostructures for High-Performance Supercapacitors

Abstract Layered double hydroxides (LDHs), featuring tunable compositions and unique layered structures, have been widely investigated as electrode materials for supercapacitors. However, their electrochemical performance is often limited by intrinsically low electrical conductiv...

Remote Moire Modulation of Decoupled Dirac Subsystems in Twisted Trilayer Graphene

Abstract Moiré superlattices are generally assumed to act only at the interface where lattice mismatch or twist occurs. Here, we study charge transport in large-angle helical twisted trilayer graphene, where interlayer tunneling is strongly reduced. When only the top monolayer g...

Atropos: Improving Cost-Benefit Trade-Off of LLM-Based Agents under Self-Consistency with Early Termination and Model Hotswap

Open-weight Small Language Models(SLMs) can provide faster local inference at lower financial cost, but may not achieve the same performance level as commercial Large Language Models (LLMs) that are orders of magnitudes larger. Consequently, many of the latest applications of LLM...

Rust’s Type Checker Implementation Is Unsound: An Empirical Study on Soundness Bugs in rustc

Rust is claimed to be a type-sound language capable of preventing various undesirable behaviors, including memory bugs. However, rustc, the official Rust compiler, is not immune to defects; it contains soundness bugs, where the compiler accepts programs that should be rejected du...

X-ray liquidography decodes complex motions in azobenzene isomerization

Abstract Capturing ultrafast structural rearrangements of organic molecules in solution remains a central challenge, with isomerization being a key example. Yet, despite decades of studies, a detailed atomic-level structural understanding of how isomerization occurs remains elusi...

Renewable power-to-heat solution integrated with glycerol-based thermal energy storage system for industrial process heat

The industrial sector is a major contributor to global greenhouse gas emissions, highlighting the need for efficient power-to-heat solutions. This study proposes a novel power-to-heat system integrated with a glycerol-based thermal energy storage and presents the first system-lev...

Time-asymptotic stability of viscous shocks for the outflow problem of one-dimensional compressible fluids of Korteweg type

We study the time-asymptotic stability of viscous-dispersive shock waves for the outflow problem of the barotropic Navier–Stokes–Korteweg equations, which describe viscous fluids with internal capillarity. Assuming that the far-field state is subsonic or transonic and that the ve...

Major Customer Network and Modern Slavery Incidents

ABSTRACT This study explores the impact of major customer network structure on the risk of modern slavery incidents. By focusing on the downstream segment of the supply chain, the study aims to clarify how relational dynamics with major customers shape a supplier's exposure to la...

Linker‐Locking Strategy for the Rigidification of Flexible Metal–Organic Framework: Structural Stabilization and Controlled ESIPT for H 2 O/D 2 O Sensing

ABSTRACT Controlling the photodynamics of excited‐state intramolecular proton transfer (ESIPT) fluorophores is crucial for sensing, due to their large Stokes shifts and dual emission. However, structural flexibility and solvent‐induced degradation often hinder isolating a single...

Dual functionality of an organic co-solvent for enhancing stability and efficiency in static zinc bromine batteries

The flammability of conventional lithium-ion batteries poses significant safety concerns, driving interest in safer alternatives. Static zinc bromine batteries (ZBBs) offer a promising solution due to their non-flammable aqueous electrolyte and low cost. However, their widespread...

Entrainment of prefrontal theta synchrony increases interbrain coupling and enhances social interaction in mouse models of autism

Social interaction requires the integration of information about self, other, and shared context. One of the proposed mechanisms supporting this coordination is interbrain synchrony – correlated neural activity between interacting individuals – yet its role in shaping social beha...

Linking Visual Properties and Aesthetic Attractiveness Through Perceived Abstraction in Abstract Art

Abstract art tends to receive lower and more variable aesthetic ratings than representational art among non-expert viewers, yet the role of abstraction in aesthetic judgment remains underexplored. We investigated whether perceived abstraction accounted for part of the relations b...

Drop‐on‐Demand Printed Negative Dielectric Anisotropy Liquid Crystal Droplets for Adaptive Complex Beam Manipulation and Assessment

ABSTRACT Adaptive manipulation of vectorial optical fields is important for optical metrology, imaging, and structured light‐related applications, yet existing approaches often rely on bulky or sequentially operated systems. Here we demonstrate an inkjet‐printed negative dielectr...

Generative AI as a Mediator in Creator Collaboration: Challenges, Design Opportunities, and Concerns

As Generative AI (GenAI) expands beyond individual workflows and becomes increasingly integrated into collaborative creative work, its potential to address the fundamental challenge of building common ground among creators with diverse expertise remains underexplored. Specificall...

Wearable photovoltaic textiles: From device technologies to long‐term reliability

Abstract Photovoltaic (PV) textiles are emerging as a promising class of energy‐harvesting systems that combine solar conversion capability with the softness, porosity, and wearability of fabrics. Unlike conventional rigid modules, PV textiles are designed to conform to the human...

Nanolayer-Confined Strain Waves in Femtosecond-Optical-Vortex-Excited Multiferroic BiFeO3
