The present study examined a sustainable chemical challenge involving the removal of acidic aqueous transition metals (M = Fe, Co, Ni, Zn, In, Sn, Al) using fishbone waste. The study was grounded in research findings indicating that hydroxyapatite, a...

Shrimp processing generates large amounts of byproducts such as shell, rich in valuable bioactive compounds, including proteins, lipids, minerals, and carotenoids. Their valorization into functional powders represents a sustainable approach for waste...

This work presents a method for producing high-purity, low-micron-size silicon particles by combining solvent refining and metal dealloying. Metallurgical-grade silicon, a feedstock material for photovoltaic and electronic applications, was mixed wit...

Emerging contaminants are increasingly recognized as persistent soil pollutants with often-unknown environmental effects, yet Mediterranean monitoring data remain scarce. This study compared three established sample preparation approaches and subsequ...

Multifunctional hybrid spheres were developed via ionic gelation, using sodium alginate as an encapsulating matrix to integrate TiO₂, Fe₃O₄, activated carbon, hypochlorite-impregnated clinoptilolite zeolite, and metallic copper, followed by chitosan...

This study reports the development, optimization and mechanistic evaluation of bio-based cellulose/lignin–tannin membrane adsorbents for the removal of representative inorganic and organic water pollutants: Cr(VI), Pb²⁺, difenoconazole (DFC) an...

Currently, approximately 80% of the energy used worldwide comes from fossil fuels. The production of bioethanol from agro-industrial waste requires pretreatment due to the latter’s rigid structure and resistance to degradation. In this work orange pe...

Expanded polystyrene (EPS) is costly to reprocess, occupies substantial landfill space, and presents significant challenges for reuse. The development of innovative methods for EPS recycling is therefore a promising area of research. This study explo...

This study presents an integrated two-step synthetic protocol for the conversion of coconut and palm oils into high-value bio-based hydrocarbons, alcohols, and aldehydes. The process employs alkaline hydrolysis followed by Kolbe electrolysis. Under r...

Allophane, halloysite, and imogolite are aluminosilicate clays, whose structures mainly contain silicon and aluminum. However, their morphologies differ markedly: allophane occurs as hollow/porous nanospheres, imogolite as single-walled aluminosilica...

Safe drinking water remains an issue all around the world, especially in arid countries that require seawater desalination to obtain safe water. This research seeks to analyze water quality at the major stages of an SWRO plant, i.e., raw seawater int...

Hydrogel-based functional materials have garnered widespread attention across various fields due to their unique three-dimensional network microstructure and versatile, tunable properties. However, owing to the absence of a systematic analysis of the...

Bisphenol A (BPA) epoxy resins are widely used because of their excellent thermal and mechanical properties but are difficult to recycle owing to their highly crosslinked network. This study investigated the effect of curing-agent chemistry on epoxy...

Electrochemical CO₂ reduction to ethanol can couple captured carbon with low-carbon electricity, but plant economics depend simultaneously on Faradaic efficiency (FE), current density, full-cell voltage, carbon and product retention, stack durability...
