Effect of process conditions for the preparation of a manganese-based coating on the surface of AZ31 magnesium alloy
(Sciendo, 2023-05-01)Manganese-based coatings on AZ31 magnesium alloy with Mg(OH)2 interlayer were prepared by hydrothermal reaction under different process conditions (temperature, time, and concentration). The harsh reaction conditions ... -
Hydrothermal synthesis and characterization of calcium phosphate-based coatings on AZ31 magnesium alloy
(Sciendo, 2023-05-01)This study aims to analyze the influence of process parameters used for hydrothermal synthesis of CaP coatings on their properties and to improve their corrosion resistance and biocompatibility compared to the substrat ... -
Improving of 100Cr6 Steel Corrosion and Wear Properties in Simulated Sea Water Environment by Tungsten-Doped DLC Coating
(MDPI, 2023-06-12)A progressive type of tungsten-doped DLC coating was applied to a quenched and tempered 100Cr6 steel with the aim to improve the wear and corrosion properties in simulated seawater conditions and to compare the performance ... -
Effect of Laser Remelting of Fe-Based Thermally Sprayed Coating on AZ91 Magnesium Alloy on Its Structural and Tribological Properties
(MDPI, 2023-06-02)An Fe-based coating was thermally sprayed onto the surface of AZ91 magnesium alloy via the High-Velocity-Oxygen-Fuel (HVOF) method. The thermally sprayed coating with a thickness of 530 ± 25 µm and a porosity of 0.7 ± 0.1% ... -
Translational Studies on the Potential of a VEGF Nanoparticle-Loaded Hyaluronic Acid Hydrogel
(MDPI, 2021-05-22)Heart failure has a five-year mortality rate approaching 50%. Inducing angiogenesis following a myocardial infarction is hypothesized to reduce cardiomyocyte death and tissue damage, thereby preventing heart failure. Herein, ... -
Effect of alkali salts on the hydration process of belite clinker
(MDPI, 2022-05-10)Belite-rich cement represents one of the low carbon footprint binders. Nevertheless, its use is ac-companied by a low initial rate of hydration. This can be partially eliminated by the grinding to high specific surfaces ... -
Degradation of P(3HB-co-4HB) Films in Simulated Body Fluids
(MDPI, 2022-05-13)A novel model of biodegradable PHA copolymer films preparation was applied to evaluate the biodegradability of various PHA copolymers and to discuss its biomedical applicability. In this study, we illustrate the potential ... -
Microstructural Characterization of Laser Weld of Hot-Stamped Al-Si Coated 22MnB5 and Modification of Weld Properties by Hybrid Welding
(MDPI, 2021-07-14)The presence of Al-Si coating on 22MnB5 leads to the formation of large ferritic bands in the dominantly martensitic microstructure of butt laser welds. Rapid cooling of laser weld metal is responsible for insufficient ... -
Stress Effect of Food Matrices on Viability of Probiotic Cells during Model Digestion
(MDPI, 2021-07-05)The aim of this study was to evaluate the influence of model (alcohol, sugar, salt, protein and acid) and real foods and beverages on the viability of probiotics during incubation and artificial digestion. Viability of ... -
Biotechnological Conversion of Grape Pomace to Poly(3-hydroxybutyrate) by Moderately Thermophilic Bacterium Tepidimonas taiwanensis
(MDPI, 2021-09-01)Polyhydroxyalkanoates (PHA) are microbial polyesters that have recently come to the forefront of interest due to their biodegradability and production from renewable sources. A potential increase in competitiveness of PHA ... -
G-quadruplexes in H1N1 influenza genomes
(Springer Nature, 2021-01-24)Background: Influenza viruses are dangerous pathogens. Seventy-Seven genomes of recently emerged genotype 4 reassortant Eurasian avian-like H1N1 virus (G4-EA-H1N1) are currently available. We investigated the presence and ... -
Facile Preparation of Porous Microfiber from Poly-3-(R)-Hydroxybutyrate and Its Application
(MDPI, 2020-01-20)In this study, we described the development of a simplified wet spinning method of the production of a novel type of porous continuous fiber based on poly-3-(R)-hydroxybutyrate (PHB). The principle of this method is ... -
The influence of quadruplex structure in proximity to p53 target sequences on the transactivation potential of p53alpha isoforms
(MDPI, 2020-01-14)p53 is one of the most studied tumor suppressor proteins that plays an important role in basic biological processes including cell cycle, DNA damage response, apoptosis and senescence. The human TP52 gene contains alternative ... -
Photoelectric Properties of Solar Cells Based on Perovskites
(Czech Technical University in Prague, 2018-03-13)Here we discuss materials and construction of particular solar cells that could be possible replacement for the current silicon-based photovoltaic cells, and methods of studying their performance. Solar cells based on the ...
