Composite coating of antibiotic gentamicin (Gent), natural polymer chitosan (CS), and hydroxyapatite (HAP) was successfully assessed by applying the electrophoretic deposition (EPD) technique. EPD performed under optimized conditions (5 V, 12 min) on pure titanium plates, to obtain HAP/CS HAP/CS/Gent composite coatings in a single step from three-component aqueous suspension, with favorable antibacterial properties. were characterized X-ray diffraction (XRD), field emission scanning electron...
Abstract Electrophoretic deposition process (EPD) was successfully used for obtaining graphene (Gr)‐reinforced composite coating based on hydroxyapatite (HAP), chitosan (CS), and antibiotic gentamicin (Gent), from aqueous suspension. The performed as a single step at constant voltage (5 V, time 12 min) pure titanium foils. influence of examined through detailed physicochemical biological characterization. Fourier transform infrared spectroscopy, field emission scanning electron microscopy,...
The electrophoretic deposition process (EPD) was utilized to produce bioactive hydroxyapatite/chitosan (HAP/CS) and hydroxyapatite/chitosan/gentamicin (HAP/CS/Gent) coatings on titanium. bioactivity of newly synthesized composite investigated in the simulated body fluid (SBF) examined by X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron microscopy. obtained results revealed carbonate-substituted hydroxyapatite after immersion SBF, emphasizing...
Smelting used to be less efficient; therefore, wastes obtained from historical processing at smelter plants usually contain certain quantities of valuable metals. Upon the extraction useful metal elements, metallurgical slag can repurposed as an alternative mineral raw material in building sector. A case study was conducted, which included investigation physico-chemical, mineralogical, and microstructural properties Pb–Zn found historic landfill near Topilnica Veles North Macedonia. The...
Background/Objectives: Magnetic resonance imaging (MRI) is widely used in diagnostics, but its effects on orthodontic materials remain a concern. This study aimed to evaluate the impact of MRI exposure at 1.5 T and 3 shear bond strength (SBS) adhesive remnant index (ARI) different bracket types (metal, self-ligating, ceramic). Methods: A total 90 extracted human premolars were divided into three groups (control, T, exposure). The bonded using Transbond XT subjected standardized...
Interest for application of hydrometallurgical processes in a processing complex sulphide ores and concentrates has increased recent years. Their provides better metal recoveries reduced emission gaseous toxic ageneses the environment. The kinetics mechanism sphalerite leaching from concentrate with sulphuric acid sodium nitrate solution at standard conditions was presented this paper. influences temperature time on degree zinc were investigated kinetic analysis process accomplished. With...
The presented work offers a novel process scheme for valorizing historical Pb-Zn slag, which involves crushing, grinding, and then using separation techniques to concentrate valuable components (nonferrous metals). This methodology could have significant impact on the global beneficiation of metallurgical slags since, in theory, it is significantly more simple, environmentally friendly, cost-effective than standard pyrometallurgical or hydrometallurgical procedures. According previous...
X-ray diffraction analysis of single crystals three new arsenates adopting apatite-type structures yielded formula Sr(5)(AsO(4))(3)F for strontium arsenate fluoride, (I), (Sr(1.66)Ba(0.34))(Ba(2.61)Sr(0.39))(AsO(4))(3)Cl barium chloride, (II), and Cd(5)(AsO(4))(3)Cl(0.58)(OH)(0.42) cadmium hydroxide (III). All are built up isolated slightly distorted AsO(4) tetrahedra that bridged by Sr(2+) in Sr(2+)/Ba(2+) (II) Cd(2+) Compounds (I) represent typical fluorapatites chlorapatites,...
Čumavići is a medium– to low–temperature hydrothermal Sb–Zn–Pb–Ag polymetallic vein–type ore deposit in the Srebrenica orefield, part of Podrinje Metallogenic District, Eastern Bosnia and Herzegovina. The occurs form simple complex veins along faults fractures, as well stockworks disseminations hosted within Neogene volcanic rocks (pyroclastics andesite lavas calc–alkaline affinity). comprises sulfides (sphalerite, galena, stibnite, pyrite, marcasite, chalcopyrite, arsenopyrite, gudmundite,...
This paper describes a promising electrophoretic deposition (EPD) approach for developing composite coatings based on chitosan with the additional components of hydroxyapatite, graphene, and gentamicin titanium substrate. Bioactive properties were investigated in vitro by immersing simulated body fluid (SBF) at 37 °C. The newly formed biomimetic layer top deposited chitosan-based Ti was confirmed X-ray diffraction, Fourier transform infrared spectroscopy, field emission scanning electron...
