Lithium Niobate Electro‐Optic Photonic Processor for Variational Quantum Eigensolver

Encoding quantum information in high-dimensional photonic states as a qudit provides a powerful route to resource-efficient quantum simulation. Among various integrated photonic platforms, lithium niobate on insulator is particularly attractive because it combines low optical los...

Therapeutic Equivalence, Immunogenicity, and Safety of Euvichol Oral Cholera Vaccine Formulations Compared with WHO-prequalified Shanchol vaccine in Healthy Children and Adults: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Preprint Description Background: Global demand for oral cholera vaccines (OCVs) has increased substantially, while the discontinuation of Shanchol has increased reliance on Euvichol-based formulations. This systematic review and meta-analysis evaluated the immunogenicity and safe...

Integrated Valorization of Macroalgae in a Recyclable Ionic Liquid: Hydrothermal Production of Formic and Levulinic Acids with Product Recovery and Biohydrogen Generation

Abstract Marine macroalgae are drawing growing interest as underutilized feedstocks for chemicals and fuels and as high-productivity, carbon-assimilating biomass that could contribute to carbon capture and sequestration strategies. Here, we investigate an ionic-liquid-assisted hy...

An open-source FPGA control architecture for solid-state spin-photon interfaces

Scalable quantum networks require quantum interfaces that coherently connect stationary matter qubits with flying photonic qubits. In solid-state defect platforms, such interfaces require coordinated optical excitation, microwave spin control, photon detection, and feedback with...

Carrier Dynamicsin Nonfullerene Acceptor OrganicPhotovoltaics through Ultrafast Spectroscopy

Abstract Nonfullerene acceptors (NFAs) have transformed organic photovoltaics (OPVs) by enabling high efficiencies at small energetic offsets, but rational progress demands a mechanistic view of photoinduced processes across femtosecond–microsecond windows. This review synthesize...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

ABSTRACT Photodetectors sensitive to the near‐infrared (NIR) range are of great importance for applications in machine vision, autonomous driving, and three‐dimensional (3D) imaging under low‐light or adverse weather conditions. Recently, two‐dimensional (2D) semiconductors have...

Chemical composition of granitic rocks and constituent minerals in the Eumseong Basin and adjacent areas, South Korea: Implications for weathering and groundwater chemistry

Abstract The chemical composition of bedrock and rock-forming minerals can influence both rock weathering characteristics and groundwater chemistry through water–rock interaction. Although plagioclase and biotite have both been widely studied in relation to these processes, detai...

Desorption-ControlledSelective Lithium Enrichmentfrom Spodumene Leachate Using H2TiO3 Adsorbent

Abstract The increasing demand for lithium has intensified the need for efficient lithium recovery processes. In this study, a selective adsorption–desorption strategy for selective lithium enrichment from spodumene leachate was developed using an H2TiO3 adsorbent. The adsorption...

MXene as conductive mortar: Assembly of Ti3C2Tx and carbon nanotube fibers into multifunctional films for EMI shielding and infrared stealth

Advanced electronic and defense systems require multifunctional films that combine electromagnetic interference (EMI) shielding and infrared (IR) stealth with mechanical robustness, high electrical conductivity, and low IR emissivity. Here, we report a mechanically strong and hig...

Reconfiguration of Localized Ruthenium Surface via Incorporating Single Platinum Atoms for Favorable Hydrogen Oxidation Catalysis

ABSTRACT Despite the fact that only 2% of active sites can satisfy hydrogen oxidation reaction (HOR) activity thanks to fast kinetics, the fuel cell anode is still dependent on catalysts with large amounts of platinum (Pt). Herein, a minimal‐cost ruthenium catalyst bearing ultral...

KiGEP: a quantitative algorithm for calculating human kidney similarity and nephrotoxicity in human kidney organoids

Kidney organoids (KOs) are being actively developed and used as models for evaluating nephrotoxicity, which is an important process during drug development. To evaluate human pluripotent stem cell-derived KOs, various lineage markers have been used to confirm KO differentiation v...

Nondestructive cyclic strain evaluation of seismic isolation bearings using Si-69-modified MWCNT/silicone rubber self-sensing composites

Conductive elastomer composites are promising for large-deformation sensing and structural health monitoring, but their QNDE application is limited by unstable electromechanical responses, resistance hysteresis, and disordered conductive-pathway rearrangement during cyclic loadin...

Mosapride promotes internalization of a TREK1–HTR4 complex and exerts rapid antidepressant-like effects

Major depressive disorder (MDD) remains a critical global health burden, and a substantial proportion of patients exhibit insufficient responses to conventional monoaminergic antidepressants. Selective inhibition of the two-pore domain potassium channel TREK1 has emerged as a pro...
