C-doped TiO2 nanotubes with pulsed laser deposited Bi2O3 films for photovoltaic application
(Ceramics International, 2022)
Anodization was used to obtain a nanotubular TiO2 photoanode on F-SnO2 glass. Subsequent annealing in the CH4 atmosphere promoted the C-doping and improved the crystallinity of the TiO2 nanotubes. The pulsed laser deposition ...
Optimization of Ciprofloxacin Adsorption on Clinoptilolite-Based Adsorbents Using Response Surface Methodology
(MDPI, 2023)
The adsorption of the antibiotic ciprofloxacin (CIP) from water solution by natural zeolite–clinoptilolite (CLI), magnetic clinoptilolite (MAG-CLI), and graphene oxide coated magnetic clinoptilolite (GO-MAG-CLI) was ...
Heterofunctional epoxy support development for immobilization of fructosyltransferase from Pectinex® Ultra SP-L: batch and continuous production of fructo-oligosaccharides
(Royal Society of Chemistry, 2022)
In this study, a heterofunctional carrier was obtained by modification of a macroporous polystyrene ion exchange resin with primary amino groups (Purolite® A109) with epichlorohydrin, in view of achieving covalent ...
The Effect of Glycol Derivatives on the Properties of Bio-Based Unsaturated Polyesters
(MDPI, 2022)
The scope of the present study was to prepare fully bio-based unsaturated polyester resins (UPRs) with comparable properties to the commercial formulations. The focus was set on the determination of the optimal prepolymer ...
Antibacterial Bio-Nanocomposite Textile Material Produced from Natural Resources
(MDPI, 2022)
Growing demand for sustainable and green technologies has turned industries and research toward the more efficient utilization of natural and renewable resources. In an effort to tackle this issue, we developed an antibacterial ...
Phytochemical Analysis, Biological Activities, and Molecular Docking Studies of Root Extracts from Paeonia Species in Serbia
(MDPI, 2024)
Without being aware of their chemical composition, many cultures have used herbaceous peony roots for medicinal purposes. Modern phytopreparations intended for use in human therapy require specific knowledge about the ...
Coupling electrokinetic with a cork-based permeable reactive barrier to prevent groundwater pollution: A case study on hexavalent chromium-contaminated soil
(Elsevier Ltd., 2022)
This work proposes an eco-efficient treatment technology for the remediation of a kaolinite-based clay soil artificially contaminated with hexavalent chromium (50 mg Cr(VI) kg–1 soil), combining electrokinetics (EK) with ...
Impact- and Thermal-Resistant Epoxy Resin Toughened with Acacia Honey
(MDPI, 2023)
High performance polymers with bio-based modifiers are promising materials in terms of applications and environmental impact. In this work, raw acacia honey was used as a bio-modifier for epoxy resin, as a rich source of ...
The Role of Cellulosic and Noncellulosic Functional Groups in the Biosorption of Lead Ions by Waste Flax Fibers
(JOURNAL OF NATURAL FIBERS, 2023)
In this study, waste flax fibers with different levels of cellulosic and noncellulosic components were obtained by oxidative and alkali treatments and used to assess the influence of the fiber’s structural and chemical ...
Recovery of bioactive molecules from Hypericum perforatum L. dust using microwave-assisted extraction
(Springer Science and Business Media Deutschland GmbH, 2024)
Microwave-assisted extraction (MAE) conditions were optimized to improve extract quality of medicinal herb — Hypericum perforatum L. (St. John’s wort) dust. Response surface methodology was applied initially to obtain the ...
