Interfacial Cofactor Recycling Electroenzymatic Platform for Endergonic CO2 Reduction

Abstract To overcome the thermodynamic barrier of “NADH-dependent CO2 reduction”, we developed a bioelectrosynthesis platform via the co-immobilization of CO2 reductase (CR) and diaphorase (DP) on a graphite electrode. A strategic protein engineering approach, utilizing carbon-sp...

High‐Mobility Chalcogenophene‐Engineered Diketopyrrolopyrrole Mixed Ionic‐Electronic Conductors With Doping Tolerance for Low‐Power Organic Electrochemical Transistors

ABSTRACT Optimizing the steady‐state performance of organic electrochemical transistors (OECTs) requires simultaneous control over both molecular‐level design and structural ordering in organic mixed ionic–electronic conductors (OMIECs). Here, we report a series of diketopyrrolop...

Phosphor‐Sensitized Ternary Organic Solar Cells Achieving 18.6% PCE via Ir(III)‐Mediated Triplet Energy Transfer and Non‐Radiative Recombination Suppression

ABSTRACT Phosphor‐sensitized organic solar cells (PS‐OSCs) enhance exciton utilization and suppress non‐radiative recombination by incorporating triplet‐enabled sensitizers into bulk‐heterojunction blends. Here, we report a green‐emitting Ir‐3 complex as a multifunctional phospho...

Season-dependent phenological responses and implications for co-occurring plants and butterflies under climate anomalies and extreme weather events

Abstract Despite extensive work on climate-driven phenological shifts, research has focused primarily on early-season events, single metrics and gradual shifts in mean climate, limiting insights into phenological responses across the full annual cycle. Using a 17-year dataset (20...

ICER-Controlled inhibitory plasticity of amygdala engram neurons regulates fear memory precision

Abstract Fear discrimination—the ability to distinguish threatening stimuli from non-threatening ones—is an essential adaptive behavior, yet the neural mechanisms underlying individual differences in discrimination precision remain unclear. Here, we show that parvalbumin-positive...

Drivers governing the seasonality of new particle formation in the Arctic

New particle formation (NPF) is the phenomenon wherein gaseous precursors form critical clusters of barely a few nanometres in diameter, after which, under favourable conditions, these particles can grow to climate-relevant sizes. Here we present measurements from 2022 to 2024 of...

SOC-Aware Control of Microgrid Energy Storage for Off-Grid Electrification Using Kalman Filter Forecasting

This paper presents a state-of-charge (SOC)-aware control strategy for standalone photovoltaic (PV)–energy storage system (ESS) microgrids to improve power reliability and operational efficiency in off-grid regions. The method integrates a Kalman Filter-based forecasting algorith...

Battery Electrode Design Process Using Deep Neural Network

Abstract The transition to electric vehicles (EVs) demands lithium-ion batteries (LIBs) customized for diverse energy and power density requirements, yet the intricate trade-offs among electrode design parameters make conventional trial-and-error optimization costly and time-cons...

Wafer-scale conformal metasurface optics

Curved and conformal optics provide additional geometric degrees of freedom that enable enhanced optical performance while satisfying non-optical constraints such as ergonomics, aerodynamics, and wearability. However, existing fabrication approaches for curved metasurfaces are li...

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...

Linking visceral fat accumulation to gut microbiota: key bacterial taxa and their roles in the glycogen synthesis pathway

Abstract Obesity, marked by visceral fat accumulation, has a complex relationship with the gut microbiome that impacts body weight and fat accumulation. However, previous studies did not account for fat distribution, reflecting only overall fat mass, leaving specifics of this rel...

Damage‐Free Passivation of Ambipolar OECTs with Fluoropolymer Film for Enhanced Performance and Stability Toward Reliable Biosignal Processing

Organic electrochemical transistor (OECT) is a promising building block for bioelectronic and neuromorphic applications due to its high transconductance and low-voltage operation. However, microstructural instability and irreversible electrochemical degradation of the organic mix...

Crystallization‐Driven Helical Conjugated Polymer Nanowires for Circularly Polarized Light‐Addressable Ferroelectric Physical Unclonable Functions

Supramolecular helices of conjugated polymers (CPs) offer versatile chiroptical selectivity, yet their responses are often limited to passive optical readouts and lack stability as nonvolatile electrical states. Here, we report crystallization-driven helical CP nanowires (NWs) th...

End-to-End Vehicle Lateral Control with Transformer-Based Perception and Intention-Aware View Weighting

Abstract This study presents ViewSelective-CIL, an end-to-end intention aware multi view lateral control framework integrating multi-view semantic perception, Transformer-based attention, and high-level command–conditioned control. RGB images are fused with YOLOPv2-based semantic...

One-DimensionalMolecular Coordinate Orders AminoAcids across Water-Mediated Processes

Abstract Amino acid behavior in water-mediated processes is not well captured by hydrophobicity or side-chain class alone, because residues with similar hydropathy can differ in charge localization, geometry, surface exposure, and hydration response. The objective of this study i...

A bstract We study information recovery in black hole evaporation using traversable wormhole protocols in AdS 2 Jackiw-Teitelboim gravity with matter fields coupled to an external bath. By introducing a simple non-local interaction between left and right radiation regions, we gen...

Affinity-tuned anti-idiotypic masking enables protease-activatable HER2-targeting antibodies with an optimized masked–unmasked dynamic range

Activatable antibodies aim to minimize on-target off-tumor toxicity by suppressing antigen binding through a masking domain that is released only upon encountering a tumor-associated stimulus. Anti-idiotypic single-domain antibodies (dAbs) raised against the complementarity-deter...

TMEM135 deficiency prevents intestinal lipid accumulation by coordinating lipid uptake and oxidation through ELOVL6-mediated PPARα activation

Abstract Excessive lipid accumulation impairs digestion and gastrointestinal function. Transmembrane protein 135 (TMEM135) is involved in lipid metabolism of various tissues. Here, TMEM135 deficiency increased intestinal lipid absorption through ELOVL6-dependent oleoylethanolamid...
