Green-Synthesized Copper Oxide-Modified Serpentine Nanocomposite for Efficient Adsorptive Removal of Malachite Green Dye: Mechanism, Thermodynamics, and Waste-to-Energy Valorization via Urea Electro-Oxidation

Malachite green (MG), a triarylmethane dye extensively used in the textile and aquaculture industries, is a persistent aquatic contaminant with documented carcinogenic, mutagenic, and teratogenic effects even at trace concentrations. In the present work, a natural, low-cost Serpentine clay was surface-modified with cop...

Experimental and Monte Carlo Insights into the Biofilm Control of Klebsiella pneumoniae Using Green-Synthesized Ag/Ni(OH)2/Clove Nanocomposites

One of the most significant challenges with disease control in humans and animals is biofilm formation by Klebsiella pneumoniae (K. pneumoniae). The current study investigated the prevalence of K. pneumoniae in fecal and milk samples from cattle and humans, along with their antimicrobial susceptibility patterns and bio...

Waste Adsorbent Valorization of Biopolymer‐Modified Zn–Fe Layered Double Hydroxides for Crystal Violet Removal and Enhanced Nonenzymatic Urea Detection

Finding suitable and inexpensive bifunctional materials that can act as adsorbents for crystal violet (CV) removal and as electrocatalysts for the electrochemical detection of urea remains one of the contemporary challenges. Waste valorization of spent wastewater nanoadsorbents is a promising route toward achieving c...

Additive-Mechanism Nanocomposite of Green-Synthesized Silver Nanoparticles and Domiphen Bromide: a Dual-Action, Sustained-Release Platform against Biofilm-Associated Infections

Comprehensive evaluation of a slag–activated carbon composite for metformin removal from wastewater and its agricultural reuse potential

Metformin, a widely prescribed antidiabetic drug, persists in aquatic ecosystems and poses toxic risks to nontarget organisms. This study synthesized a novel composite adsorbent from steel slag and activated carbon (2 : 1 ratio) for efficient metformin removal from water, then evaluated the spent adsorbent as a soil am...
