Chitosan–Sargassum fusiforme Polyphenol Edible Films: From Physicochemical and Bioactive Characterization to Shelf-Life Extension of Refrigerated Golden Pompano Fillets

The practical application of active food packaging materials is increasingly constrained by performance degradation and functional oversimplification. Although Sargassum fusiforme polyphenols (SP) possess potent antioxidant activity, their potential in edible films remains unexpl...

Linking molecular composition of organic aerosols to reactive oxygen species formation using an MCR-VK framework

Abstract. Reactive oxygen species (ROS) formation by atmospheric fine particulate matter (PM) is widely implicated in adverse health effects, yet the molecular determinants of particle-level ROS formation remain poorly constrained, largely due to the chemical complexity of organi...

Calibration and crop-induced footprint dynamics of cosmic-ray neutron sensing in maize cropland

Cosmic-ray neutron sensing (CRNS) provides continuous, non-invasive estimates of field-scale soil water content, but retrieval performance depends on site calibration, crop growth, and temporal variation in the sensing footprint. This study combined five field calibration campaig...

A Spatiotemporal Framework for Quantifying and Projecting Soil Organic Carbon in Grasslands of China

Accurate estimation of grassland soil organic carbon (SOC) stocks is essential for understanding carbon dynamics, yet estimates of soil organic carbon density (SOCD) in China remain uncertain due to differences in data sources and methods. To address this issue, we developed a sp...

A performance-based multivariable weighting framework for WRF parameterization-scheme selection

Abstract. The selection of optimal physical parameterization schemes is a major source of uncertainty in WRF model simulations. A comprehensive evaluation of model performance requires simultaneous consideration of multiple output variables. However, existing multivariate approac...

Comparison of One-Dimensional and Quasi-Two-Dimensional Friction Models for Hydraulic Transient Response and Energy Dissipation in Viscoelastic Pipelines at Different Water Temperatures

Abstract In chemical process systems, high-density polyethylene (HDPE) piping is widely used for conveying thermally conditioned liquids because of its corrosion resistance and operational flexibility; however, its pronounced viscoelastic response during hydraulic transients can...

Interactions between microplastics from agricultural films and soil in regulating atrazine adsorption: A mechanistic and environmental relevance study

The widespread application of agricultural films has resulted in the accumulation of microplastics (MPs) in soils, creating a coexistence with pesticides like atrazine. This study investigates the environmentally relevant interactions between field-aged polyethylene agricultural...

A pair of chitosan receptors confer broad-spectrum fungal resistance

Chitosan, a major fungal cell wall component, activates plant immunity, yet the underlying perception mechanism remains unknown. In this study, we identified OsFID1, an apoplast-localized DUF26 domain protein, as a chitosan-binding receptor essential for chitosan-triggered immuni...

Influence of Rotational Effects on Droplet Trajectories and Sprinkler Spray Uniformity

A three-dimensional droplet motion model considering the rotational effect of the sprinkler tray was established in a fixed reference frame for low-pressure rotary sprinklers to reveal the effects of tray rotation of a rotary sprinkler on the flight trajectories of water droplets...

A Carboxymethyl Cellulose Hydrogel Switch Enabling pH-Responsive Fertilizer

Abstract The Green Revolution boosted crop yields with synthetic fertilizers, but their high solubility causes environmental pollution and poor synchronization with crop nutrient demands. To address this problem, we developed green intelligent fertilizers (GIF) using a pH-respons...

Cross-Field Transfer of UAV-Based Winter Wheat Yield Prediction: Model Transferability and Sample Efficiency

Unmanned aerial vehicle (UAV) remote sensing is widely used for plot-scale crop yield prediction, but model performance may decline when models are transferred across fields with different crop, environmental, management, and sensing conditions. This study evaluated the cross-fie...

IbMYB11 Involved in Drought Stress Responses Through Association with Flavonoid Metabolism in Sweet Potato

Sweet potato (Ipomoea batatas (L.) Lam.) is a high-yielding crop that serves as both a food source and a raw material for industrial processing. Drought stress severely impairs sweet potato yield and quality. A MYB-type transcription factor, IbMYB11, was previously identified as...

One‐Step Induction of Oogonia‐Like and Pro‐Spermatogonia‐Like Cells From Porcine Pluripotent Stem Cells

ABSTRACT Pigs share a germ cell regulatory network highly similar to that of humans, yet lack a robust system for inducing and expanding germ cells from pluripotent stem cells, impeding large‐animal gametogenesis research. Here, we established a modular platform capable of effici...

Centrifugal Microfluidic Soil-to-DNA Preparation for the Portable Detection of Phytophthora infestans Using a CRISPR/Cas12a-Based Quantum Dot Fluorescent Lateral Flow Assay

Abstract Portable detection of soil-borne pathogens is constrained by laborious soil sample preparation and nucleic acid extraction. Here, we report a centrifugal Soil-on-a-Disc (SoaD) microfluidic chip for rapid soil-to-DNA preparation with automated on-chip clarification and DN...

Agronomic and Nutritional Perspectives on Vegetable Crops in Africa

ABSTRACT Vegetable production plays a crucial role in food security, nutrition, and livelihoods across Africa. Yet, it faces persistent challenges related to climate variability, water scarcity, soil degradation, and limited access to agricultural inputs. This review synthesizes...

Accurate β-Casein Allergen Quantification in Processed Foods via an Isotope-Labeled Full-Length Protein Internal Standard
