SUSTAINABLE DYEING OF TEXTILE FIBER WITH ACTIVE BACTERIAL PIGMENT (2026)

Biocolorants are pigments extracted from microorganisms that may replace synthetic dyes used in textile industry for different purposes. Pseudomonas aeruginosa is the only natural source of pyocyanin (PYO), a bioactive molecule that may add functionality to textile materials. In this study, 84.7 mg of PYO was extracted from the strain P. aeruginosa TGC04 and samples of 100% cotton jersey were dyed by the exhaustion method (500 and 1000 µg.mL-1 of PYO), using NaHCO3 as a mordant. There was approx

The Economic Benefit of Recycling: An Application of Travel Cost Method to Estimate the Consumer Surplus (2025)

Abstract This article presents the first analysis in the literature that measures the economic benefit of drop-off recycling in terms of consumer surplus (CS). CS, a measure of the economic benefit that consumers receive from participating in economic activities, is estimated using a single-site travel cost method application based on survey data. Our findings indicate that the total CS residents of Monongalia County receive from drop-off recycling is $1,317,960 annually.

Composite mechanical performance of prefabricated concrete based on hysteresis curve equation (2022)

Abstract The angle steel-concrete column used in the new frame structure means that the rigid angle steel is placed in the column instead of the longitudinal reinforcement. The steel plate hoop welded to the longitudinal angle steel is used instead of the stirrup to form a spatial steel frame and concrete component. To ensure the normal use of existing houses in the building and adding floors, avoid transferring the load during the construction phase to the roof of the original

A study of Cu sputtering on the polyphenylene sulfide fiber with plasma surface treatment (2025)

Abstract Sputtering is an effective technique for coating various substrates. However, the high energy involved can cause damage to polymers. In this study, polyphenylene sulfide, an engineering plastic known for its excellent thermal properties, was coated with Cu to impart electrical conductivity. To minimize polymer degradation during sputtering, oxygen plasma treatment was employed prior to deposition to investigate its effect on the process. The plasma treatment facilitated the atta

Enhanced Methane Production from Anaerobic Co-Digestion of Wheat Straw Rice Straw and Sugarcane Bagasse: A Kinetic Analysis (2021)

Future energy and environmental issues are the major driving force towards increased global utilization of biomass, especially in developing countries like Pakistan. Lignocellulosic residues are abundant in Pakistan. The present study investigated the best-mixed proportion of mechanically pretreated lignocellulosic residues i.e., wheat straw and rice straw (WSRS), bagasse and wheat straw (BAWS), bagasse, and rice straw (BARS), bagasse, wheat straw, and rice straw (BAWSRS) through anaerobic co-di

Effect of Nano-Magnetite and Ethanol on Methane Production in the Anaerobic Digestion of Wheat Straw (2022)

HighlightsStudied mesophilic and thermophilic anaerobic fermentation of wheat straw with nano-magnetite (Fe3O4) and ethanol.The maximum biogas yield of 421.5 mL/g in mesophilic AD was 60.8% higher than control.Revealed the mechanism of nano-Fe3O4 and ethanol addition to promote biogas production.Abstract. This study investigated the mesophilic and thermophilic anaerobic fermentation of wheat straw with nano-magnetite (Fe3O4) and ethanol addition. The effects of ethanol addition on the biogas yie

Redox reactions in chronic pain: mechanisms and relevance in fibromyalgia (2025)

Fibromyalgia (FM) is increasingly recognized as a disorder driven by oxidative stress, mitochondrial dysfunction, and neuroinflammation, contributing to pain sensitization and fatigue. This review explores the role of redox imbalance in FM and evaluates potential therapeutic interventions. A scoping literature search was conducted using PubMed, Scopus, and Google Scholar. Findings indicate elevated oxidative stress markers (MDA, 4-HNE), impaired antioxidant defenses [CoQ10 (Coenzyme Q10), SOD, c
