Nanocomposite co-catalysts, based on smectite and biowaste-derived carbon, as peroxymonosulfate activators in degradation of tartrazine
(Elsevier, 2022)
Chitosan (Ch)-derived from biowaste along with smectite, an abundant clay mineral, were used in a low-cost and eco-friendly synthesis of a new type of catalyst. Nanocomposite catalysts constituted of Co supported on smectite ...
Degradation of three typical hydroxamic acids collectors via UVA-B activated H2O2 and persulfate: Kinetics, transformation pathway, DFT calculation and toxicity evaluation
(Elsevier, 2023)
This work systematically studied the kinetics and mechanism of degradation of salicylhydroxamic acid (SHA), benzhydroxamic acid (BHA) and N-hydroxyphthalimide (NOP) by UVA-B/H2O2 and UVA-B/peroxodisulfate (PDS). UVA-B ...
Resource utilization of steel converter slag: Efficient degradation of typical organic flotation reagent α-nitroso-β-naphthol via the synergy of radical and non-radical pathways
(Elsevier, 2023)
The organic pollution generated during production and processing in the mining area seriously endangers the ecological security of the surrounding environment. In this study, degradation of α-nitroso-β-naphthol (αNβN), a ...
Еmpirical and process-based models predict enhanced beech growth in European mountains under climate change scenarios: a multimodel approach
(Elsevier, 2023)
Process-based models and empirical modelling techniques are frequently used to (i) explore the sensitivity of tree growth to environmental variables, and (ii) predict the future growth of trees and forest stands under ...
Absorption and fluorescence spectral properties of azo dyes based on 3-amido-6-hydroxy-4-methyl-2-pyridone: Solvent and substituent effects
(Elsevier, 2020)
A series of nine 5-(4-substituted phenylazo)-3-amido-6-hydroxy-4-methyl-2-pyridones were synthesized and characterized by FT–IR, 1H and 13C NMR, UV–Vis, and PL spectroscopy. Photophysical properties of the dyes were examined ...
Novel polyurethane network/organoclay nanocomposites: Microstructure and physicochemical properties
(Elsevier, 2022)
A series of novel polyurethane network/organoclay nanocomposites (PUN-NCs) with different soft segment contents (30–60 wt%) was prepared by in situ polymerization in solution and characterized. PU network (PUN) was made ...
Multistep Approach Points to Compounds Responsible for the Biological Activity and Safety of Hydrolates from Nine Lamiaceae Medicinal Plants on Human Skin Fibroblasts
(MDPI, 2023)
As byproducts of essential oil distillation, hydrolates are used in natural cosmetics/biomedicine due to their beneficial skin effects. However, data on their safety with relevant biological targets, such as human skin ...
Bacterial nanocellulose as green support of platinum nanoparticles for effective methanol oxidation
(Elsevier BV, 2022)
Bacterial nanocellulose, BNC, has emerged as a new class of nanomaterials recognized as renewable, biodegradable, biocompatible and material for versatile applications. BNC also proved as a perfect support matrix for ...
Cysteine and cerium as green corrosion inhibitors for AA7049: Mixture vs. complexation
(Elsevier, 2022)
In this work new green corrosion inhibitors based on the synthesized cerium-cysteine complex on AA7049 aluminum alloy were analyzed and compared to the mixture of CeCl3 and cysteine in 0.1 M NaCl. The complex structures ...
Efficient photocatalytic hydrogen production over titanate/titania nanostructures modified with nickel
(Elsevier, 2019)
Nickel-modified titanate/TiO2 catalysts were prepared by deposition of nickel ions onto hydrothermally prepared titanate supports, followed by hydrogen temperature-programmed reduction. Two different nickel precursors ...
