Improvement in cavitation resistance of poly (vinyl butyral) composite films with silica nanoparticles: A technical note
(Polymers & Polymer Composites, 2021)
In this study poly (vinyl butyral)/silica (PVB/SiO2) composite films were subjected to the cavitation process. The experiments were carried out with a 10 wt.% PVB solution in ethanol. Silica nanoparticles were added into ...
Spray drying of Gentiana asclepiadea L. root extract: Successful encapsulation into powders with preserved stability of bioactive compounds
(Industrial Crops and Products, 2021)
Willow gentian as a source of bitter compounds is traditionally used for digestive disorders. Gentiana root extract was spray dried using five different carriers (maltodextrin, whey protein, pectin, starch, gelatine) at ...
A closed cycle of sustainable development: Effective removal and desorption of lead and dyes using an oxidized cellulose membrane
(Elsevier B.V., 2023)
Oxidized cotton linters, TOCell, were used as an adsorbent or derived membrane there from by linters
cross-linking with citric acid. The adsorption/desorption study of Pb2+, methylene blue (MB), and crystal
violet (CV) ...
Mn-Fe Layered Double Hydroxide Modified Cellulose-Based Membrane for Sustainable Anionic Pollutant Removal
(Springer, 2024)
This study aimed to investigate the adsorption of As(V), phosphate, and textile dye Acid Green 25 (AG-25) on layered double hydroxides Mn-Fe_LDH and corresponding membranes (wCell/Mn-Fe_LDH). The wCell membrane, derived ...
Influence of lyophilized Thymus serpyllum L. extracts on the gastrointestinal system: Spasmolytic, antimicrobial and antioxidant properties
(South African Journal of Botany, 2021)
In the presented study, polyphenol profile, spasmolytic, antimicrobial and antioxidant properties of lyophilized Thymus serpyllum extracts were examined. The main phenolic acid in the extracts was rosmarinic acid, followed ...
Formulation and characterization of liposomal encapsulated systems of bioactive ingredients from traditional plant mountain germander (Teucrium montanum L.) for the incorporation into coffee drinks
(Elsevier Ltd., 2022)
Conventional and innovative (microwave-assisted and subcritical water extraction) techniques were applied to investigate the bioactive content of traditional plant - Teucrium montanum. Verbascoside and echinacoside, ...
The influence of different extraction conditions on polyphenol content, antioxidant and antimicrobial activities of wild thyme
(Journal of Applied Research on Medicinal and Aromatic Plants, 2021)
The aims of the presented study were the investigation of the effect of different ultrasound-assisted extraction conditions (particle size, solid-to-solvent ratio, ethanol concentration and time) on polyphenol and flavonoid ...
Dental material based on poly(methyl methacrylate) with magnesium-aluminum layered double hydroxide (MgAl-LDH) on bio-silica particles
(Elsevier B.V., 2024)
The MgAl-LDH@SiO2 particles are prepared by the coprecipitation of LDH on silica originating from plants.Particles are of submicron size and are well dispersed in the matrix. Composites consisting of PMMA reinforcedwith ...
Synthesis, characterization and SAR studies of bis(imino)pyridines as antioxidants, acetylcholinesterase inhibitors and antimicrobial agents
(Academic Press Inc Elsevier Science, San Diego, 2020)
In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase ...
From mycelium to spores: A whole circle of biological potency of mosaic puffball
(Elsevier Science Bv, Amsterdam, 2019)
Methanol extracts of mosaic puffball (Handkea utriformis, Bovistella utriformis, Lycoperdon utriforme, Calvatia utriformis - current name is a subject of debate), from three different stages - mycelium (HUMIC), immature ...
