Leveraging Electroosmosis in OmpF for Robust Peptide Sensing

Abstract Peptide sensing and sequencing are essential for elucidating sequence-function relationships and evaluating the peptide drug quality. Nanopore electrochemistry enables label-free characterization of peptide composition, structure, and interactions at the single-molecule...

Decomposition of phengite from residual subducted slabs enhancing lithospheric tin mineralization: Insights from K–Li–Nd isotopes

The sources and roles of volatiles in tin (Sn)-related magmatic systems remain controversial. We present integrated K–Li–Nd isotopic, trace element, and volatile data from Late Cretaceous Xishan Sn-mineralized granites in the southern margin of the South China Block to constrain...

Spatially selective development finance: The uneven geography of county-level local government bonds in China

Local government bonds (LGBs) constitute a form of spatially selective development finance, combining top-down selectivity in quota allocation and bottom-up selectivity in borrowing capacity and mechanisms under uneven institutional and market conditions. Drawing on a dataset cov...

Attribution, zonation, and simulation of spatiotemporal distribution of negative oxygen ions in mountainous megacity: A case study of Chongqing, China

Negative oxygen ions (NOI) are key indicators of urban ecological quality. However, NOI dynamics in mountainous megacities remain poorly understood. A key challenge lies in translating complex environmental observations into interpretable knowledge for environmental planning rath...

Internal Variability Dominates the Spatial Heterogeneity of Recent Trends in Eurasian Winter Cold Extremes

Abstract Eurasia, with its large and climate‐vulnerable population, has experienced increased cold extremes despite global warming, yet their pronounced spatial heterogeneity remains poorly understood. We examine low‐frequency trends in Eurasian cold extremes over recent decades....

Skeletal Distortion Manipulation in 2D–3D-Fused Boron Clusters Enables Solid-State Luminescence and Photothermal Conversion

Abstract Luminescent π-conjugated materials are central to modern optoelectronics, yet they are typically constructed from planar, rigid molecular frameworks. Herein, we introduce a conceptually distinct luminescent molecular platform based on three-dimensional (3D) boron cluster...

Giant Ferroelectric Domain Wall Conductance in MoS2/PbTiO3 Heterostructure for High-Density Memory

Abstract Domain wall (DW) electronics hold promise for high-density computing, but their implementation is limited by low read currents and high operating voltages in bulk ferroelectric oxides. Here, we present a monolayer molybdenum disulfide (MoS2)/PbTiO3 (PTO) van der Waals (v...

High-frequency Earth rotation parameters estimated from VLBI observations during CONT campaigns

The Desai–Sibois high-frequency Earth rotation parameter (HF-ERP) model provides one of the most detailed descriptions of diurnal and sub-diurnal variability up to date. However, it still underrepresents short-period signals, underscoring the need for reliable, observation-based...

Chemically Initiated Single-Module Afterglow Imaging via Lesion-Microenvironment-Activated Cyanine–Fe Coordination

Abstract Afterglow luminescence imaging offers high sensitivity, deep-tissue readability, and persistent emission for image-guided surgery, but most current probes still require external energy activation, limiting autonomous lesion reporting and increasing the risk of off-target...

A 128−Channel 0.2–8.2 V Calibrated DAC IC Achieving 0.26−LSB DNL and 0.71−LSB DVO for Photonic Computing

Photonic computing systems require large numbers of accurate programmable voltages for photonic weight programming and device bias control. This paper presents a 128−channel digital−to−analog converter (DAC) implemented in a 250 nm BCD high−voltage CMOS process. A code−dependent...

Historical Trade Liberalization and Modern Innovation: Evidence From China's Treaty Ports
