Disparate evolution mechanisms and optical absorption for transboundary soot particles passing through inland and sea pathways [PDF]

Atmospheric Chemistry and Physics
Soot particles, as a type of warming aerosols, play a critical role in climate warming. During transport, these particles undergo atmospheric condition-dependent aging processes that influence their microphysical and optical properties.

Soot particles filtration - humidity influence

, 2019
One of the most frequently use methods to purify air contaminated by particles in many industrial processes is filter media. Although the performance of filter media is relatively well documented under standard conditions (humidity and ambient temperature), few studies are interested in the interaction between moisture and the deposition of particles ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

In Situ Investigation of Microstructure Evolution and Stress Generation During Low‐Pressure Carburizing and Quenching by Means of Synchrotron X‐Ray Diffraction

steel research international, EarlyView.
This study uses in situ synchrotron X‐ray diffraction at the German Electron Synchrotron to analyze low‐pressure carburizing (LPC) in steels. The findings reveal surface carbon saturation and carbide formation kinetics, and phase‐specific stress development during quenching. The results show carbide kinetics depend on steel grade and size, while stress

The Impact of Environmental Pollution and Climate Change on Allergic Rhinitis and Lung Diseases

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Environmental pollution and climate change seriously affect human health, leading to the onset and exacerbation of chronic respiratory diseases, such as allergic rhinitis and lung diseases. Over the past several decades, increasing air pollution and environmental exposure owing to global urbanization, industrialization, and rapid economic ...

Exploring Soot Particle Concentration and Emissivity by Transient Thermocouples Measurements in Laminar Partially Premixed Coflow Flames

Energies, 2017
Soot formation in combustion represents a complex phenomenon that strongly depends on several factors such as pressure, temperature, fuel chemical composition, and the extent of premixing. The effect of partial premixing on soot formation is of relevance

Sustainable dyeing of silk with curled dock (Rumex crispus) extract for trace element removal, ultraviolet protection, antimicrobial and anti‐oxidant activity

Coloration Technology, EarlyView.
Abstract This study investigated the dyeability and functionality of silk dyed with curled dock leaf extract. The effects of sugar content and turbidity in the extracted dye solution on dyeing were analysed, along with K/S values and colour fastness, under varying temperatures and times.

Textile and colour defect detection using deep learning methods

Coloration Technology, EarlyView.
Abstract Recent advances in deep learning (DL) have significantly enhanced the detection of textile and colour defects. This review focuses specifically on the application of DL‐based methods for defect detection in textile and coloration processes, with an emphasis on object detection and related computer vision (CV) tasks.
