Third-Harmonic Generation in Crumpled Silicon Nanomembranes

Abstract Silicon nanomembranes provide mechanically compliant devices for strain engineering. Here, we investigate third-harmonic generation in flat and crumpled silicon nanomembranes of 15 and 35 nm using polarization-resolved third-harmonic generation microscopy with ab initio...

Dry Mask Transfer Lithography for High-Resolution Patterning of Nanomaterials and Molecular Interfaces on Arbitrary Substrates

This study introduces dry mask transfer lithography as a versatile microfabrication strategy that integrates the patterning resolution of photolithography with the substrate adaptability of soft lithography. In this method, a photoresist mask is first patterned on an elastomeric...

Functionalized Silica-Coated Metallic Replicas of Intracellular Protein Assemblies

Abstract To replicate hierarchical biological architectures, biotemplating leverages diverse biological structures as templates for inorganic materials. Among the various inorganic materials explored in biotemplating, silica is an attractive material because of its stability and...

Exploring the potential of AI-driven brain–computer interfaces for Alzheimer’s disease: an integrated framework for diagnosis and therapeutic intervention

Early diagnosis and timely intervention are critical in Alzheimer's disease (AD), yet conventional assessments fail to capture longitudinal neural dynamics. Although traditional biomarker frameworks offer essential pathological insights, they remain constrained by high costs and...

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...

Alzheimer’s disease through the lens of mesenchymal drift: the collapse of cellular identity

Cellular identity is maintained by precise epigenetic regulation, but chronic stress and aging can disrupt this control, leading to mesenchymal drift (MD). Unlike the coordinated process of epithelial-mesenchymal transition (EMT), MD is a stochastic, lineage-independent phenomeno...

Stable Oil-in-Water Nanoemulsions Stabilized by Polygonatum sewerzowii Extract: A Plant-Derived Alternative to Synthetic Surfactants

Growing demand for clean-label ingredients has intensified the search for sustainable plant-derived emulsifiers capable of replacing synthetic surfactants in nanoformulations. In this study, the emulsifying potential of crude Polygonatum sewerzowii extract (PSE), obtained by opti...

Electrolyte Lubricants for Solid-State Batteries

Abstract Solid-state batteries (SSBs) promise higher energy density and improved safety, but interparticle voids and unstable solid–solid interfaces still limit their performance. Here, we translate the concept of lubrication into an electrolyte-lubrication strategy for SSBs. We...

Oligoethylene Glycol Side‐Chain Engineering of Y6‐Derived Nonfullerene Acceptors for Thermally Induced Spontaneous Pseudo‐Planar Heterojunction Organic Photodetectors

ABSTRACT Dark current density ( J D ) fundamentally limits the noise characteristics and detectivity of organic photodetectors (OPDs), arising primarily from reverse‐bias carrier injection and trap‐mediated leakage pathways in donor‐acceptor (D‐A) bulk‐heterojunction (BHJ) active...

Genistein as a potential hormetic regulator of proteostasis in neurodegeneration and aging

As global populations increase in age, the incidence of neurodegenerative diseases and dementia is rising; however, symptomatic and disease-modifying therapies deliver only modest benefits. This gap has fueled interest in aging-targeted interventions spanning lifestyle, nutrition...

Bio-inspired Terrain Perception for Snake Robots: Spectral Analysis of Vertical Undulation and Sidewinding

While snake robots offer exceptional potential for exploration in confined and unstructured environments, their capacity for active adaptation is currently hindered by a lack of robust terrain classification. Inspired by the mechanosensory perception of biological snakes, this st...

Robotic Palpation for Spatiotemporal Arterial Pulse Quantification and Mapping Using Multilevel Microdome‐Based Soft Pressure Sensors

ABSTRACT Humanoid robots have advanced capabilities through physical and physiological examinations, but their reliance on visual information limits biological‐object assessment, underscoring the need for tactile perception. Current tactile systems primarily detect basic contact...

AI models as consciousness attributors: how LLMs ascribe consciousness to other agents

Research on AI consciousness has largely focused on whether AI systems are conscious and how humans attribute consciousness to them. Yet large language models (LLMs) increasingly function as consciousness attributors, generating judgments about whether and to what degree other en...

Profiling of pyrimidine and arginine metabolism in NSCLC identified Malate-Aspartate Shuttle as the backbone network

Abstract Metabolic shifts are crucial for cellular proliferation, however, the roles of various metabolic pathways and their interconnections in NSCLC remain unclear. This lack of understanding in metabolic shifts precludes better cancer management as well as effective therapeuti...

Sticker Valence Governs Chain Collapse and Liquid‐Liquid Phase Separation in Peptide‐Inspired Associative Polymers

Biomolecular condensates, including membraneless organelles, form through liquid-liquid phase separation (LLPS) driven by sequence-specific associations within intrinsically disordered protein regions. Understanding how sticker valence governs LLPS is essential for predicting pat...

Structure‐Engineered Nanoporous Vanadium Oxide Memristors for Reconfigurable Synapse–Neuron Integration and Synergistic Robotic Motion

ABSTRACT Neuromorphic sensory‐to‐motor interfaces require compact devices that can combine nonvolatile synaptic weight storage with volatile neuronal firing, yet these functions typically rely on distinct material and circuit mechanisms. Here, we report a structure‐engineered VO...

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

ABSTRACT Dynamic molecular martensites exhibit large, reversible deformations and high force densities. However, device integration has been limited by the brittleness and poor formability of single crystals. Here, we report a thin‐film route that translates molecular cooperativi...

A Novel Methodology for Temporal Analysis of Consumer Wearable Sleep Data: Feasibility and Application to Early Cognitive Impairment

While sleep disturbances are recognized as early markers of Alzheimer's disease (AD), the practical application of gold-standard polysomnography (PSG) for long-term monitoring is limited. This study aims to establish a novel methodological framework for the time-series analysis o...
