Experimental study on methane hydrate formation in the presence of sodium dodecyl sulphate under the influence of different physical properties of silica and composite systems

Abstract Natural gas hydrates naturally occur in pores of porous media. This study presents the first systematic investigation of methane hydrate formation in sub‐millimetre silica particles (0.4 and 0.7 mm) and larger sizes (1, 2, and 3 mm) as benchmarks. The combined matrix (0....

Comparison of the Photodegradation of Pharmaceuticals and Personal Care Products (PPCPs) in Water and Ice

Abstract Photochemical reactions are prevalent in natural aquatic environments and play a crucial role in aquatic ecosystems. Sunlight-induced photodegradation is particularly effective in degrading various pharmaceuticals and personal care products (PPCPs). However, the photoche...

Population-Balance Modeling of Oligomer Evolution and Reactor-Configuration Effects in Poly(ethylene terephthalate) Glycolysis

Abstract In zinc acetate-catalyzed poly(ethylene terephthalate) (PET) glycolysis in ethylene glycol, PET conversion and bis(2-hydroxyethyl) terephthalate (BHET) yield cannot resolve the oligomer distributions governing separation and reactor staging. We develop a repeat-unit-cons...

Deep learning-based crack detection with visual interpretability for rock mass engineering in complex environments

Accurate detection of rock cracks underpins structural health monitoring for rock mass engineering structures. However, existing detection methods suffer from the strong nonlinearity and multi-scale variability of underground crack morphologies, as well as severe interference fro...

Overview of the research and application of carbon-based nano-fluorescent tracer in low-permeability reservoir

As the emerging fluorescent material, carbon-based nano-fluorescent tracers exhibit excellent fluorescent properties and surface modifiability. They hold significant application potential in fields such as oilfield tracing, biomedical imaging, and water treatment. However, the de...

Nonlinear Stress Amplification Mechanism of Shell-to-Bottom Fillet Welds in Large Oil Storage Tanks Induced by Local Bottom Plate Detachment Under Harmonic Settlement

Although previous studies have investigated global deformation responses of large storage tanks subjected to uneven foundation settlement, the stress redistribution mechanism of shell-to-bottom fillet welds caused by local bottom plate detachment remains unclear. In this study, a...

Kinetics of methane hydrate formation in rhamnolipid solution

Abstract Solidified natural gas (SNG) offers a promising route for natural gas storage and transportation, but its practical application is hindered by slow hydrate formation kinetics and the environmental concerns of chemical surfactants. This study investigates the environmenta...

Coregulation of Properties of Poly(butylene succinate)-Based Quaternary Copolyesters via Branched and Linear Diol Modification

Abstract Poly(butylene succinate) (PBS), a representative bio-based and biodegradable polymer, exhibits great potential in food packaging and agricultural mulch films. However, its applications are limited by high crystallinity, low toughness, low degradation rate, and poor oxyge...

Research Progress on the Application of Ceramic Membranes in Wastewater Treatment of the Petroleum and Petrochemical Industry

Abstract Ceramic membranes have become a key separation technology for treating complex pollutants in the petrochemical industry due to their excellent resistance to extreme conditions, high separation efficiency, and extended service life. This review systematically summarizes t...

Design of a bionic flapping wing mechanism based on RSSR mechanism and analysis of aerodynamic characteristics

Abstract Flapping-wing aircraft have broad application prospects in scientific research and engineering. Based on the spatial offset RSSR mechanism, this paper designs a bionic flapping-wing structure. By deriving the kinematic equations of the mechanism and taking the preset fla...

Computed tomography-derived body composition parameters as potential predictors of severity and adverse outcomes in viral pneumonia: a retrospective study

Background Following the COVID-19 pandemic, co-infections with multiple respiratory viruses have become increasingly common, complicating the accurate prediction of disease progression and prognosis. This study assessed the use of computed tomography (CT)-derived body composition...
