ABSTRACT 5‐Hydroxymethylfurfural (HMF) can be electrocatalytically oxidized to 2,5‐furandicarboxylic acid (FDCA) with concurrent hydrogen evolution, providing a sustainable route for biomass valorization and clean energy generation. In this study, we synthesized a three‐dimension...

Sustainable syngas production by photothermal dry reforming of bio-ethanol over a Ni/Mn0.1Ce0.9O2 catalyst

Syngas production via the dry reforming of ethanol (EDR) offers a sustainable pathway for carbon capture and bio-energy valorization, yet traditional thermal catalysis is plagued by severe coking and metal sintering. In this study, a Ni/Mn 0.1 Ce 0.9 O 2 catalyst was designed to...

Projected Primal–Dual Gradient Preference Optimization Under Category-Wise Split-Conformal Safety Constraints for Large Language Model Post-Training

Preference optimisation improves helpfulness, but a single aggregate safety penalty lets frequent harm categories dominate the objective while rare ones bear the residual risk. This paper models post-training as a vector-constrained programme: the pairwise preference loss is mini...

Multispecies interfacial regulation via keratin-engineered separators for dendrite-free aqueous zinc metal anodes

Aqueous zinc-ion batteries hold great promise for stationary energy storage and personal electronics, yet their practical application is hindered by uncontrolled Zn dendrite growth and parasitic reactions. Herein, a sustainable keratin-functionalized glass-fiber separator (GF@WK)...

Shrimp Processing By‐Products as Food Ingredients: Sensory‐Functional Co‐Optimization, Ingredient Readiness, and Design Strategies

Shrimp processing side streams are increasingly considered circular resources, yet their food use remains limited by a gap between compound recovery and ingredient-level validation in target food systems. This review examines how head and cephalothorax fractions, shells, trimming...

The unique role of bromine in NaF crystallization of photo-thermo-refractive glass

Photo-thermo-refractive (PTR) glass generates a refractive-index modulation through photothermally induced NaF nanocrystallization, making it essential for volume Bragg gratings. The halide co-dopant determines how silver nanoparticle templates (Ag NPs@AgX, X = Cl, Br, I) steer N...

Cu-Modified Zirconium Metal Organic Framework DUT-67 Schottky Heterojunction for Full-spectrum Antibiotic Degradation: Mechanistic Insights, Degradation Pathways, and Toxicity Assessment

Photocatalysis is an efficient approach for antibiotic remediation, but rapid carrier recombination remains a key challenge. Here, we construct an oxygen-vacancy rich Cu/DUT-67 Schottky junction photocatalyst for antibiotics degradation. Surface oxygen vacancies provide abundant...

Stage-Specific Effects of Spatial Organization on Visual Search Under Clutter: Behavioral and Eye-Movement Evidence

Whether a well-organized scene facilitates visual search may depend on when in the search process the benefit is expressed. We tested this possibility in a virtual-office task in which 48 adults searched for targets varying in salience. Salience was manipulated between participan...

Sliding mode control for trajectory tracking of autonomous underwater vehicles via predefined time disturbance observer

This paper investigates the trajectory tracking control problem with prescribed performance for autonomous underwater vehicles (AUVs) subject to lumped disturbances composed of model uncertainties and unknown time-varying external disturbances. A practical predefined-time Lyapuno...

Digestive Fate of a Seaweed-Yak Meat Protein–Polysaccharide Matrix under Simulated Elderly Gastrointestinal Dysfunction: Nutrient Release, Antioxidant Response, and Peptidomic Remodeling

Abstract Age-related gastrointestinal dysfunction may alter the digestive fate of composite foods. Using a static in vitro model, we compared a seaweed-yak meat matrix under four simulated older-adult gastrointestinal conditions: normal gastric and intestinal function, isolated i...

Design of a 2D Rulkov neuronal hyperchaotic map: Dynamical analysis and application in medical target encryption

A lightweight encryption framework for medical image data is presented in this paper. A two-dimensional Hénon–Rulkov neuronal hyperchaotic map(2D-HRNHM), compressed sensing, and object detection technology are integrated to realize lightweight image encryption. The 2D-HRNHM chaot...

Fucus vesiculosus-Derived Fucoidan Mitigates Recognition Memory Deficits in Association with Modulation of the Microbiota–Gut–Brain Axis in Adenine-Induced Chronic Kidney Disease Mice

Chronic kidney disease (CKD) induces systemic oxidative stress and inflammation, leading to secondary cognitive impairment. The mechanisms by which marine-derived fucoidan exerts neuroprotection remain incompletely understood. Here we show that oral administration of Fucus vesicu...
