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...

A Dispersant‐Driven Carbon‐Binder Domains Homogeneity in High‐Energy‐Density Electrodes for Lithium‐Ion Batteries

Achieving high energy density in lithium-ion batteries (LIBs) requires electrodes with a high fraction of active materials. An extreme reduction of inactive components such as conductive additives and binders can limit electron transport and undermine electrode integrity, thereby...

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...

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...

Liter-Scale PrecisionSynthesis and Measurement ofNano-to-Micrometer Scale PSNPs with Graphene Liquid Cells

Abstract Monodisperse polystyrene nanoparticles (PSNPs) have great potential as standard materials in various fields, including environmental analysis, biological research, and instrumental calibration. However, reproducible liter-scale synthesis of PSNPs with controlled sizes ac...

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...

Graphitic Grain‐Network Nanoarchitecture for Ultrahigh‐Rate and Exceptionally Durable Potassium Ternary Intercalation

ABSTRACT Potassium–ternary graphite intercalation compounds (K + ‐T‐GICs) are promising high‐power potassium‐ion storage materials, but their low reversible capacity and poorly understood electrolyte‐dependent behavior have limited their practical viability. Herein, this sensitiv...

Single-vesicle heterogeneity and uptake of extracellular vesicles affected by oncogenic KRAS and BRAF revealed by proteomics and nano-flow cytometry

Extracellular vesicles (EVs) facilitate intercellular communication through the transfer of bioactive molecules that modulate tumor behavior. In this study, we demonstrate that oncogenic KRAS- and BRAF-mutations alter EV composition, modify surface properties, and impact intracel...

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...

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...
