Electrochemical synthesis and characterization of poly(o-toluidine) as high energy storage material
(Elsevier Ltd, 2019)
Poly(o-toluidine) (POT) is electrochemically synthesized on graphite electrode at constant current density of 1.5 mA cm−2 from aqueous electrolyte of 1.0 mol dm−3 H2SO4 and 0.25 mol dm−3 o-toluidine. Electrochemical ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier Ltd, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
Thermal analysis of polylactic acid under high CO2 pressure applied in supercritical impregnation and foaming process design
(Elsevier B.V., 2019)
Thermal properties of extrusion and injection grade polylactic acid (PLA) were analysed using high pressure differential scanning calorimetry (HP-DSC) under CO2 pressures of up to 50 MPa. The greatest depression of melting ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Doping of TiO2 nanotubes with nitrogen by annealing in ammonia for visible light activation: Influence of pre- and post-annealing in air
(Elsevier Ltd, 2019)
The ∼60 nm wide and ∼2 μm long TiO2 nanotubes were obtained by anodization of Ti films sputtered on F-doped tin oxide glass. For N-doping the samples were annealed in ammonia atmosphere. The effect of pre- and post-annealing ...
A new kinetic model for the common juniper essenstial oil extraction by microwave hydrodistillation
(Chemical Industry Press, 2019)
The main objective of the present study was to model the kinetics of essential oil extraction from swelled ground juniper berries by classic hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD). A new ...
Soft 3D hybrid network for delivery and controlled release of poorly soluble dihydropyrimidinone compound: An insight into the novel system for potential application in leukemia treatment
(John Wiley and Sons Inc., 2022)
Researchers are faced with everyday demands for safer and more efficient therapy for many diseases, especially serious one such as various types of cancer. Numerous anticancer drugs are poorly-water soluble and therefore ...
Ru layers electrodeposited onto highly stable Ti2AlC substrates as cathodes for hydrogen evolution in sulfuric acid solutions
(Elsevier, 2016)
In this work, the hydrogen evolution reaction (HER) was studied on Ru coated Ti2AlC electrodes in 1.0 mol dm(-3) H2SO4 at 25 degrees C. Ti2AlC was found to be a highly stable substrate in sulfuric acid solutions due to the ...
Physico-chemical, structural, and adsorption properties of amino-modified starch derivatives for the removal of (in)organic pollutants from aqueous solutions
(International Journal of Biological Macromolecules, 2023)
In this study, an environmentally sustainable process of crystal violet, congo red, methylene
blue, brilliant green, Pb2+, Cd2+, and Zn2+ ions adsorption from aqueous solutions onto aminomodified starch derivatives was ...
Hydroxyapatite-based dental inserts: microstructure, mechanical properties, bonding efficiency and fracture resistance of molars with occlusal restorations
(John Wiley and Sons Inc., 2024)
This study aimed to (1) comparatively analyze properties of Sr- and Mg-substituted hydroxyapatite (HAP)-based dental inserts; (2) evaluate insert bonding to restorative materials, and (3) evaluate the effect of doped HAP ...
