Distribution of radionuclides and associated radiological risk assessment of soils from Niška Banja, Serbia
(Akademiai Kiado ZRt.Springer, 2024)
The activity concentrations of 226Ra, 232Th and 40K were determined in 43 soil samples collected from 0 to 10 cm and 10 to 50 cm depths of Niška Banja region, Serbia, using a low background gamma spectroscopy with 3″ × 3″ ...
INSIGHT INTO SORPTION AND ANTIOXIDANT PROPERTIES OF ANTIBACTERIAL WOUND DRESSINGS COMPOSED OF VISCOSE FABRICS FUNCTIONALIZED WITH CHITOSAN AND CHITOSAN-BASED NANOPARTICLES
(Publishing House of the Romanian Academy, 2022)
Wound dressings designed with simultaneously adequate antibacterial, sorption, and antioxidant properties enable proper wound healing. Since the antibacterial properties have already been proven in our previous studies, ...
Predicting percutaneous permeation for new succinimide derivatives by in vitro and in silico models
(Journal of Molecular Structure, 2023)
Percutaneous permeation of twenty-four newly synthesized succinimide derivatives was evaluated using parallel artificial membrane permeability assay (PAMPA) with 70% silicone oil and 30% isopropyl myristate. Different ...
The development of a process simulator transport model for RO systems
(Elsevier Ltd, 2022)
This paper introduces solute-solvent interactions onto a universal transport modeling approach that has been recently introduced for predicting RO membrane performance. The mathematical modeling framework utilizes chemical ...
Kinetic Model for Galacto-Oligosaccharide Synthesis
(American Chemical Society, 2022)
A new micro-kinetic model is proposed for galacto-oligosaccharide (GOS) synthesis with β-galactosidase from Aspergillus oryzae. Several kinetic models with similar reaction mechanisms, i.e., steps and kinetic constants, ...
Study on thermal stability of water-based polyurethanes derived from hydroxypropyl terminated poly(dimethylsiloxane)
(Springer Science and Business Media B.V., 2024)
In this paper, thermal and thermo-oxidative stability of three water-based polyurethanes (PUs) derived from hydroxypropyl terminated poly(dimethylsiloxane) (HPT-PDMS) were studied. The structural properties of the synthesized ...
Blocking the 2,3-butanediol synthesis pathway of Klebsiella pneumoniae resulted in l-valine production
(Springer Science and Business Media B.V., 2022)
Klebsiella pneumoniae is a 2,3-butanediol producing bacterium. Nevertheless, a design and construction of l-valine production strain was studied in this paper. The first step of 2,3-butanediol synthesis and branched-chain ...
Statistical methods for designing a Geiger–Muller counter suitable for an early warning system
(Elsevier B.V., 2022)
The paper discusses statistical methods that can be applied when constructing the Geiger–Muller counters to obtain the same response to radiation, regardless of their dimensions. This issue is relevant for the improvement ...
Volumetric and Transport Properties of Isoamyl Acetate Based Binary Systems-Experimental Determination and Modeling
(American Chemical Society, 2022)
Three binary mixtures consisting of isoamyl acetate and 1-butanol or isobutanol or isopentanol were experimentally investigated in terms of their density, viscosity refractive index, and ultrasonic speed of sound, in the ...
Multiblock copolymers containing poly(butylene succinate) and poly(ε-caprolactone) blocks: Effect of block ratio and length on physical properties and biodegradability
(Springer Science and Business Media B.V., 2022)
In order to obtain polymers with preserved thermal properties and tunable biodegradability multiblock copolymers comprising blocks of biodegradable polyesters poly(ε-caprolactone) (PCL) and poly(butylene succinate) (PBS) ...
