2D Covalent Organic Frameworks as Robust n‐Type Organic Mixed Ionic‐Electronic Conductors for Electrochemical Transistors

ABSTRACT Organic mixed ionic‐electronic conductors (OMIECs) with exclusive electrochemical modulation and coupling between ions and electrons have exhibited intriguing efficiencies in bioelectronics, logic circuits, and wearable devices. However, OMIECs are typically linear polym...

Faulted Rock Slope Stability Under Blasting Excavation Using Copula‐Based Rotated Anisotropic Random Fields

ABSTRACT Blasting excavation can induce permanent displacement in faulted rock slopes and adversely affect slope stability. Most existing stability assessments use deterministic approaches and therefore do not adequately account for the spatial variability and cross‐correlation o...

Mo-doped NiFe-LDH drives efficient electrooxidation of biomass-derived furfurals to maleic acid

Abstract The renewable electricity-driven conversion of biomass-derived compounds into dicarboxylic acids represents an alternative to fossil-based processes, but achieving high selectivity and activity under mild conditions remains a significant challenge. Herein, we report Mo-d...

Supplementation with Agrobacterium sp. FN01-Derived Crude Product Dominated by L-β-Galactoglucan Enhances Growth Performance and Nutrient Utilization and Modulates Intestinal Microbiota in Pigs

Polysaccharides are well known for their immunomodulatory properties and gut microbiota-regulating functions; however, their digestive stability and structure-dependent biological mechanisms remain poorly understood. This study investigated the in vitro enzymatic resistance and i...

Bycatch risk of threatened and protected marine species in China’s seas and adjacent waters

Large marine animals face severe threats from industrial fisheries globally, with bycatch recognized as a primary driver of population declines. This challenge is particularly pronounced in China’s seas and adjacent waters—a region of extraordinary biodiversity yet intense fishin...

Simultaneous adjustment of accelerator alignment reference networks based on the classical stochastic model

Simultaneous adjustment is a critical technique for constructing high-precision accelerator alignment reference networks, which integrates measurements from multiple laser trackers. To address the specialized stochastic model used by the Unified Spatial Metrology Network (USMN) i...

Optimal standardized ileal digestible lysine levels in low-protein diets: Effects on performance of lactating sows and their offspring.

Accelerating Materials Discovery: A Review of Machine Learning in X‐Ray Absorption Spectroscopy

X‐ray absorption spectroscopy (XAS) is a critical technique for probing the local structural and electronic properties of materials. Advanced synchrotron radiation facilities generate complex, high‐dimensional spectra, which pose significant challenges for traditional analysis me...

Irrigation Regimes Shape Vertical Salt Distribution in Coastal Saline–Alkali Farmlands: A PLS-SEM Analysis of Direct Ion Input and Physicochemical Pathways

Soil salinization constrains agricultural sustainability in coastal low plain regions, yet the mechanisms regulating salt spatial heterogeneity under different water management regimes remain unclear. This study investigated soil soluble ion distribution and influencing factors a...

Atomic‐Scale Mechanisms of Anisotropic Thermal Decomposition in GeSn Alloys With Stepwise Pinning

ABSTRACT Thermal decomposition of GeSn layers detrimentally affects device performance, while the governing mechanisms remain shrouded by the presence of SiO 2 passivation. In this work, we elucidate the atomic‐scale decomposition of GeSn during thermal degradation using in situ...

Topographic decoupling of tree-mortality disturbances drives contrasting soil carbon fates via divergent microbial strategies

Climate change is exacerbating tree mortality worldwide, threatening the stability of forest soil organic carbon (SOC) stocks. However, how SOC responds to tree mortality amid co-occurring disturbances remains mechanistically unresolved. Here, we demonstrate that topography spati...

Six-fold reduction in ocean heat content estimate uncertainty since 1960

Abstract Ocean heat content (OHC) dominates Earth’s energy imbalance, but its uncertainty has not been fully understood. Here, we construct a Large-Ensemble to comprehensively quantify the OHC uncertainty from global to regional scales since 1955, and consider eight groups of err...
