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

Thermal Degradation and Thermal Decomposition of Plasticized PVC Including POSS Additives for PVC Compounds: Mechanisms, Impact, and Performance of Standards

Journal of Vinyl and Additive Technology, EarlyView.
Additives' structures. ABSTRACT Poly(vinyl chloride) has been a key polymeric material since its commercial production in 1931, demonstrating versatility across numerous industries due to its compatibility with various additives. PVC's inherent properties, flame retardance, durability, and recyclability make it ideal for building and construction ...

Soot aerosols from commercial aviation engines are poor ice-nucleating particles at cirrus cloud temperatures [PDF]

Atmospheric Chemistry and Physics
Ice-nucleating particles catalyze ice formation in clouds, affecting climate through radiative forcing from aerosol–cloud interactions. Aviation directly emits particles into the upper troposphere where ice formation conditions are favorable.

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.
