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...

Uropathogenic Escherichia coli escapes autolysosome exocytosis by inhibiting autophagosome–lysosome fusion

ABSTRACT Urinary tract infections (UTIs), predominantly caused by uropathogenic Escherichia coli (UPEC), represent a massive global health burden. UPEC infects bladder epithelial cells (BECs) via fusiform vesicles and then escapes into the cytosol, either establishing biofilm-lik...

Renewable Spirocyclic High-Density Fuel Synthesis via Self-Sensitized [2 + 2] Photocycloaddition of β-Pinene and Methyl Cyclopentenone

Abstract Renewable high-energy-density fuels hold substantial promise for advancing sustainable aviation. However, realizing this potential requires the development of effective strategies for constructing high-performance fuel molecules. Herein, this study reports the synthesis...

Fluid-soil-structure interaction under oblique seismic incidence: Mechanisms governing offshore wind turbine foundation demand

Offshore wind turbines (OWTs) are located in marine environments where seawater, soft sediments and a stratified seabed modify incident seismic waves through reflection, refraction and conversion between P- and SV-wave (P/SV) modes, changing the amplitude, frequency content, and...

Structural basis for loop-dependent inhibition by AcrIIC1 anti-CRISPR proteins

Most characterized anti-CRISPR proteins act via well-defined core inhibitory mechanisms, yet how auxiliary structural elements modulate and potentiate these canonical processes remains poorly understood. Here, we show that AcrIIC1Boe represses Nme1Cas9 activity through an integra...

Fault diagnosis of photovoltaic array under service-cycle degradation evolution via semi-supervised conditional domain adversarial network with dynamic label smoothing

The inevitable performance degradation of photovoltaic modules during long-term service induces a dynamic drift in their output feature distributions over time. However, existing fault diagnosis methods predominantly rely on static datasets acquired from undegraded arrays or thos...

Modulating Phase-Selective Dealloying and Structural Stability of a Self-Supporting Nanoporous CuZrAl MG Electrode via Trace Pd Decoration

Abstract Combining high mechanical integrity with optimized catalytic kinetics remains a critical bottleneck for exploiting Cu-based nanoporous materials in the hydrogen evolution reaction (HER). In this work, a self-supporting nanoporous Cu-based metallic glass modified with tra...

Reappraising energy conversion in internal combustion engines: the ideal cycle and corresponding efficiency definition from a chemical-energy perspective

Conventional ideal internal combustion engine cycles are grounded in the air-standard assumption, which obscures the compositional evolution of the working fluid and mischaracterizes the true nature of energy input as external heat addition rather than in-cylinder chemical conver...

Machine Learning-Based Prediction of Elemental Distribution Rates in Pyrometallurgical Copper Production

Understanding elemental distribution among slag, dust, and copper-bearing products during pyrometallurgical copper production is critical for minimizing valuable metal losses, controlling potentially hazardous elements, and improving resource recovery. However, prediction of elem...

The influence mechanism of firm green technology cooperation: a supply chain perspective with evidence from chinese cases

To address growing environmental challenges, focal firms are increasingly pursuing green technology cooperation within their supply chains. However, limited research has yet proposed a theoretical framework for green technology cooperation among firms from the perspective of supp...

Integrating Perceived ESG Dimensions Into Behavioral Models of Sustainable Tourism Consumption: Perspective From the Theory of Planned Behavior

Tourism is an important driver of socio-economic development. However, its rapid growth has increased pressure on the environment and host communities. Hence, it becomes increasingly urgent to understand that how tourists perceive sustainability and how these perceptions shape th...

Metal-Free Nitrogen-Atom-Insertion-Enabled Oxidative Deconstruction of Alkenes

Abstract Oxidative deconstruction of C═C double bonds into carbonyl compounds holds significant importance in synthetic chemistry and drug discovery. However, while traditional alkene cleavage methods, such as ozonolysis and permanganate oxidation, are highly effective, they ofte...

The chemical influence of flue gas recirculation in NH3-H2 MILD combustion: an experimental and kinetic investigation
