Preclinical functional characterization methods of nanocomposite hydrogels containing silver nanoparticles for biomedical applications
(Springer, New York, 2020)
Nanocomposite hydrogels that contain silver nanoparticles (AgNPs) are especially attractive for various biomedical applications (e.g., antimicrobial wound dressings, coatings and soft tissue implants) due to strong ...
Resistance to Pit Formation and Pit Growth for Different Tempers of AA2024 Aluminium Alloy in Presence of Benzotriazole
(Korean Inst Metals Materials, Seoul, 2020)
The paper analyses the corrosion behaviour of both naturally and artificially aged AA2024 aluminium alloy in NaCl solution in the presence of the corrosion inhibitor benzotriazole (BTA). The differences between these two ...
Structural, microstructural and mechanical properties of sintered iron-doped mullite
(Elsevier, Amsterdam, 2020)
The study of an effect of iron doping on the structural, microstructural and mechanical properties of sintered iron-doped mullite is presented. The results of phase composition, performed in detail by Mossbauer spectroscopy ...
On the photophysical properties of a liquid crystal dimer based on 4-nitrostilbene: A combined experimental and theoretical study
(Journal of Molecular Liquids, 2021)
A new liquid crystal dimer, 1,12-bis(4-(2-(4-nitrophenyl)ethenyl)phenoxy)dodecane, was synthesized and structurally characterized. The compound exhibited enantiotropic nematic phase. The spectroscopic properties were ...
Can Fiber-post Placement Reinforce Structurally Compromised Roots?
(Quintessence Publishing Co Inc, Hanover Park, 2020)
Purpose: Immature teeth are characterized by short roots, thin root canal walls, and open apices, which makes them prone to fracture. The aim was to investigate whether fiber-post placement had an influence on the fracture ...
Natural Macromolecules as Carriers for Essential Oils: From Extraction to Biomedical Application
(Frontiers Media Sa, Lausanne, 2020)
Essential oils (EOs) and their main constituents, the terpenes, are widely studied, mostly relating to their antioxidant ability and bioactivity, such as antimicrobial, anticancer, anti-inflammatory, and range of other ...
Nutrition and Health Claims Spectra of Pre-Packaged Foods on Serbian Supermarket Shelves: A Repeated Cross-Sectional Study
(Nutrients, 2021)
Nutrition and health claims (NHCs) are a powerful tool that influence consumers' final decision on the choice of food products. The purposes of this repeated cross-sectional study were to (i) assess the prevalence of ...
Removal of Nickel Ions from Aqueous Solutions by 2-Hydroxyethyl Acrylate/Itaconic Acid Hydrogels Optimized with Response Surface Methodology
(Gels, 2021)
The adsorption of Ni2+ ions from water solutions by using hydrogels based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA) was studied. Hydrogel synthesis was optimized with response surface methodology (RSM). The ...
