Asymmetric Dual Sites Enable Spatially Resolved Biradical‐Mediated C–N Coupling for N,N‐Dimethylformamide Photoelectrosynthesis

ABSTRACT N,N‐dimethylformamide (DMF) is a quintessential industrial solvent and precursor, and its energy‐intensive, high‐temperature conventional synthesis necessitates the development of mild, sustainable biomass‐derived alternatives. Photoelectrocatalysis (PEC) offers a promis...

Equatorial Indian Ocean productivity over the last 200,000 years and links to deep circulation variations

Ocean circulation plays a key role in regulating atmospheric carbon dioxide levels during Pleistocene glacial-interglacial cycles. However, spatial responses of the oceans remain poorly constrained because reliable records from important carbon exchange regions, such as the equat...

Efficient Discovery of Motif Transition Process for Large-Scale Temporal Graphs

Understanding the dynamic transition of motifs in temporal graphs is essential for revealing how graph structures evolve over time, identifying critical patterns, and predicting future behaviors, yet existing methods often focus on predefined motifs, limiting their ability to com...

Preliminary Kinetic Assessment of Quality Deterioration and Shelf-Life Estimation in Yellowfin Tuna Under Different Constant Storage Temperatures

The quality of yellowfin tuna is highly vulnerable to microbial proliferation, which accelerates quality deterioration and spoilage throughout storage. In this study, the dynamic changes in biogenic amines (BAs), total volatile basic nitrogen (TVB-N), and total plate count (TPC)...

A quorum sensing antagonist with dual bacterium- and host-directed anti-pathogenic activity against Pseudomonas aeruginosa

Pseudomonas aeruginosa is a major opportunistic pathogen whose clinical management is increasingly compromised by antibiotic resistance and biofilm-associated persistence. Anti-pathogenic strategies that attenuate virulence without inhibiting bacterial growth offer a promising al...

Changes in the tropical rainfall seasonal cycle dominated by mesoscale convective systems

Global warming is reorganizing atmospheric circulation and hydroclimate, and tropical rainfall is a key manifestation of this response. Yet how these large-scale changes are translated into the tropical rainfall seasonal cycle remains uncertain because organized convection, which...

Numerical Study on the Stability of a Riprap for Submarine Cables and the Protective Solution Under Waterflow Incidence

This study presents a numerical investigation into riprap stability for submarine cable protection under high-speed incident waterflow conditions. A coupled CFD-DEM numerical model, implemented within the ANSYS 2024 R1 platform, was developed and validated against controlled labo...

Programmable multifunctional microrobots for synergistic cuproptosis-immunotherapy

Abstract Oral microrobots as drug carriers have shown great promise in enhancing the therapeutic efficacy of colorectal cancer (CRC). However, existing platforms frequently lack the programmable temporal precision required to execute complex, multi-stage dosing regimens. Here, we...

Trends in the PromisingFunctional Pigment, Phycocyanobilin:Preparation, Health Benefits, and Utilization

Abstract Phycocyanobilin (PCB) is a linear tetrapyrrole chromophore covalently bound to phycocyanin that is widely distributed in cyanobacteria and certain microalgae. PCB has attracted increasing attention, because of its well-defined structure, excellent biocompatibility, and d...

Accumulation, toxicity, and underlying mechanisms of short-chain chlorinated paraffins in early life stages of Chlamys farreri

Short-chain chlorinated paraffins (SCCPs) have attracted extensive attention due to their wide distribution and associated human exposure risks. Although marine bivalves exhibit a high accumulation capacity for SCCPs, their toxicological effects and underlying mechanisms remain p...

Paleomagnetic Reconstruction of the Early Triassic Paleogeographic Position of the South Yellow Sea and Its Geological Significance

Most studies on the Early Triassic paleomagnetism of the Yangtze Block (YB) have concentrated on the Western to Middle parts, but the South Yellow Sea (SYS) in the Eastern YB (EYB) is relatively lacking. To ascertain the paleogeographic position of the SYS, we isolated the charac...

Ag-iPyramidSERS Enables Single-Particle Detectionof Sub-200 nm Nanoplastics in Real Samples

Abstract The detection of nanoplastics smaller than 200 nm is critical because of their potential to cross biological barriers, yet it remains a significant analytical challenge in complex environmental matrices due to weak signals and matrix interference. Here, we developed an o...

Aerobic Denitrification Reactor with Pseudomonas chloritidismutans K14 Improves Water Quality and Growth of Hybrid Grouper (Epinephelus fuscoguttatus ♀ × Epinephelus lanceolatus ♂) in RAS

The intensification of mariculture has increased nitrogen and phosphorus pollution in aquaculture wastewater. Conventional treatments often prove inefficient under saline conditions. To address this challenge, we developed an innovative aerobic denitrification reactor using Pseud...

Advancing Energy Efficiency in Smart Windows via Dual‐Responsive Electro‐Thermochromism

ABSTRACT Implementing dynamic smart windows is imperative toward the construction of net‐zero buildings. However, the prevailing ion (de‐)embedding‐based electrochromic (EC) or thermosensitive hydrogel‐based thermochromic (TC) windows fail to achieve large optical modulation acro...

Antarctic Circumpolar Current creates a boundary limiting the meridional dispersal of bacteria in the Southern Ocean

Impact statement As the world's largest ocean current in terms of volume transport, the Antarctic Circumpolar Current (ACC) significantly affects the movement of heat and water in the Southern Ocean. However, the impact of the ACC on the biogeographic distribution of marine bacte...
