La(OH)3 Multi-Walled Carbon Nanotube/Carbon Paste-Based Sensing Approach for the Detection of Uric Acid—A Product of Environmentally Stressed Cells
(MDPI AG, 2022)
This paper aims to develop an amperometric, non-enzymatic sensor for detecting and quantifying UA as an alert signal induced by allergens with protease activity in human cell lines (HEK293 and HeLa). Uric acid (UA) has ...
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, ...
Biodegradable Hydrogel Scaffolds Based on 2-Hydroxyethyl Methacrylate, Gelatin, Poly(β-amino esters), and Hydroxyapatite
(MDPI, 2022)
New composite 3D scaffolds were developed as a combination of synthetic polymer, poly(2-
hydroxyethyl methacrylate) (PHEMA), and a natural polymer, gelatin, with a ceramic component,
nanohydroxyapatite (ID nHAp) dopped ...
A Metabonomic View on Wilms Tumor by High-Resolution Magic-Angle Spinning Nuclear Magnetic Resonance Spectroscopy
(MDPI, 2022)
Pediatric cancer NMR-metabonomics might be a powerful tool to discover modified
biochemical pathways in tumor development, improve cancer diagnosis, and, consequently, treatment.
Wilms tumor (WT) is the most common kidney ...
Methacrylate-Based Polymeric Sorbents for Recovery of Metals from Aqueous Solutions
(MDPI, 2022)
The industrialization and urbanization expansion have increased the demand for precious and rare earth elements (REEs). In addition, environmental concerns regarding the toxic effects of heavy metals on living organisms ...
Immobilization of Horseradish Peroxidase on Magnetite-Alginate Beads to Enable Effective Strong Binding and Enzyme Recycling during Anthraquinone Dyes’ Degradation
(MDPI, 2022)
The aim of this study was to investigate covalent immobilization of horseradish peroxidase (HRP) on magnetic nanoparticles (Mag) encapsulated in calcium alginate beads (MABs) for color degradation, combining easy and fast ...
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 ...
Biodegradability Assessment of Polyester Copolymers Based on Poly(ethylene adipate) and Poly(ε-caprolactone)
(MDPI AG, 2022)
Biodegradable polymers contain chains that are hydrolytically or enzymatically cleaved, resulting in soluble degradation products. Biodegradability is particularly desired in biomedical applications, in which degradation ...
Freshwater systems and ecosystem services: challenges and chances for crossfertilization of disciplines
(Springer, 2022)
Freshwater ecosystems are among the most
threatened in the world, while providing numerous
essential ecosystem services (ES) to humans. Despite
their importance, research on freshwater ecosystem
services is limited. ...
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, ...
