Structural insights and comparative electrocatalytic performance of citric acid-functionalized Luffa aegyptiaca and Pt-Pd/MWCNT-Luffa composites for the degradation of acetaminophen in aqueous media

Emerging contaminants, such as acetaminophen, pose a critical threat to aquatic ecosystems and human health due to their persistence in water and the difficulty of their removal using conventional methods. In this work, Luffa aegyptiaca biomass was valorized via citric acid funct...

Catalytic valorization of wastewater sludge into aviation fuel-range hydrocarbons over Ni, Cu, Co and ZrO2/SAPO-11 catalysts

This work presents an innovative valorization strategy for wastewater sludge to produce aviation fuel range hydrocarbons via the catalytic processing of esters, using Ni, Cu, Co, and ZrO 2 -based catalysts supported on SAPO-11 zeolite. Biofuel was produced under two reaction atmo...

Biocatalytic Transformation of Industrial Polyurethane Waste Using Laccases: Toward Environmentally Sustainable Management Strategies for Plastic Pollution

Polyurethane foams (PUFs) account for approximately 5.3% of global plastic production and are highly persistent in the environment due to their resistance to degradation. Their progressive fragmentation into micro- and nanoplastics, together with the presence of hazardous additiv...

Integrated Fertilization Improves Tomato Productivity, Fruit Quality, and Soil Properties

Intensive horticultural production relies heavily on mineral fertilizers, which may negatively affect soil quality and long-term sustainability. Integrated fertilization represents an alternative for reducing these risks; however, its effects on the soil–plant–fruit system remain...

Tailoring structural and optical properties of CdSe thin films deposited with nominal Tb³⁺ precursor concentrations (0–10 mol%) via chemical bath deposition

Cadmium selenide (CdSe) thin films were deposited on glass substrates by chemical bath deposition using nominal Tb³ ⁺ precursor concentrations of 0 –10 mol% at 80 °C. The influence of increasing Tb precursor concentration on the structural, morphological, and optical properties o...

Sex Differences in Oxidative Stress and Depression-Like Behavior Following Chronic Lead Exposure from Pregnancy to Adulthood

Abstract Lead (Pb) is a neurotoxic heavy metal that crosses the placental barrier and may affect fetal development. However, the effects of chronic developmental Pb exposure on oxidative stress, stress-related endocrine responses, and depression-like behavior, particularly regard...

Behavioural impact of microplastics on zebrafish development

Microplastic (MP) pollution in aquatic environments is ubiquitous and characterized by particles of highly irregular shapes. Yet, most laboratory studies examining MPs impacts on aquatic species rely on pristine polymer spheres, which poorly reflect the diversity and complexity o...
