Bioactive Interpenetrating Hydrogel Networks Based on 2-Hydroxyethyl Methacrylate and Gelatin Intertwined with Alginate and Dopped with Apatite as Scaffolding Biomaterials
(Switzerland : Multidisciplinary Digital Publishing Institute (MDPI), 2022)
Our goal was to create bioimitated scaffolding materials for biomedical purposes. The guiding idea was that we used an interpenetrating structural hierarchy of natural extracellular matrix as a “pattern” to design hydrogel ...
Characterization of Defined Pt Particles Prepared by Ultrasonic Spray Pyrolysis for One-Step Synthesis of Supported ORR Composite Catalysts
(MDPI, 2022)
Polygonal Pt nanoparticles were synthesized using ultrasonic spray pyrolysis (USP) at different precursor concentrations. Physicochemical analysis of the synthesized Pt particles involved thermogravimetric, microscopic, ...
The new exopolysaccharide produced by the probiotic strain L. reuteri B2: extraction, biological properties, and possible application for Ni2+ ion removal from the contaminated water
(Springer, 2022)
As one of the most promising groups of microbes, lactic acid bacteria (LAB) can synthesize metabolites that can be used in different industries over the world, mainly in the pharmaceutical, food, and dairy industries. In ...
Ibuprofen and diclofenac sodium adsorption onto functionalized minerals: Equilibrium, kinetic and thermodynamic studies
(Elsevier, 2022)
Cationic surfactant - octadecyldimethylbenzyl ammonium chloride (ODMBA) was used for modification of the three natural raw materials - bentonite, kaolin and zeolite. Adsorption of ODMBA by minerals occurred via ion exchange ...
Degradable 2-Hydroxyethyl Methacrylate/Gelatin/Alginate Hydrogels Infused by Nanocolloidal Graphene Oxide as Promising Drug Delivery and Scaffolding Biomaterials
(MDPI, 2022)
The design and evaluation of novel 2-hydroxyethyl methacrylate/gelatin/alginate/
graphene oxide hydrogels as innovative scaffolding biomaterials, which concurrently are the suitable
drug delivery carrier, was proposed. ...
Coupling AFM, DSC and FT-IR towards Elucidation of Film-Forming Systems Transformation to Dermal Films: A Betamethasone Dipropionate Case Study
(MDPI, 2022)
Polymeric film-forming systems have emerged as an esthetically acceptable option for targeted, less frequent and controlled dermal drug delivery. However, their dynamic nature (rapid evaporation of solvents leading to the ...
Challenges in determining the electrochemically active surface area of Ni-oxides in the oxygen evolution reaction
(Elsevier, 2022)
Thin films of Ni-oxy-hydroxides of different composition and thickness were electrochemically grown on Ni foil electrode: hydrated α-phase, anhydrous β-phase, and two mixed α- and β-phase electrodeposited by potential ...
Improvement of theoretical UV–Vis spectra calculations by empirical solvatochromic parameters: Case study of 5-arylazo-3-cyano-1-ethyl-6-hydroxy-4-methyl-2-pyridones
(Elsevier, 2022)
In order to improve the performance of theoretical UV–Vis spectra predictions, a theoretical and experimental study of solvatochromic properties of ten azo pyridone dyes has been performed. For quantitative estimation of ...
Immobilization of ArRMut11 omega-transaminase for increased operational stability and reusability in the synthesis of 3α-amino-5α-androstan-17β-ol
(Elsevier, 2022)
The aim of this research was to improve the operational stability and enable the reusability of ω-transaminase for synthesis of new enantiopure chiral amines of steroids. Dihydrotestosterone was used to optimize the synthetic ...
An Integrated Approach in the Assessment of the Vlasina River System Pollution by Toxic Elements
(Switzerland : Frontiers Media S.A., 2022)
Increasing pollutant levels in surface water are a very important problem in developing countries. In Serbia, the largest rivers are transboundary rivers that cross the border already polluted. Taking this into account, ...
