The current trend in innovative bioactive materials for dental and orthopedic applications
(Savez hemijskih inženjera Srbije, 2024)
Bioactive materials for the repairand regeneration of human bone tissue, as well as for the restoration of teeth, are the focus of numerous studies in the field of biomaterials.Orthopaedic surgeons ...
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 ...
Spatial Variability of Rare Earth Elements in Groundwater in the Vicinity of a Coal-Fired Power Plant and Associated Health Risk
(MDPI, 2024)
This study investigated the occurrence and distribution of rare earth elements (REEs), including 14 lanthanoids, scandium (Sc), and yttrium (Y), in groundwater around a large coal-fired thermal power plant (TPP). The ICP-MS ...
Real-time application and modelling of the NOx-sorption reaction on a particulate calcium carbonate surface-flow filter exposed to combustion exhaust
(Springer, 2024)
Of major interest, especially in city environments, and increasingly inside vehicles or industrial plants, is the drive to reduce human exposure to nitrogen oxides (NOx). This trend has drawn increasing attention to ...
Two-phase electro-magneto-fluid dynamics model and its computational fluid dynamics implementation
(AIP Publishing, 2024)
In this work, we present a two-phase electro-magneto-fluid dynamics (EMFD) model that merges electromagnetics and fluid dynamics. The model is suitable for use in computational fluid dynamics (CFD) software and was ...
Mechanical properties and thermal shock resistance of anorthite ceramics obtained by slip casting
(Elsevier Ltd., 2024)
Anorthite ceramics (CaAl2Si2O8) was obtained by slip casting of water suspension of kaolin (Al2O3·2SiO2·2H2O) and CaCO3 as a source of CaO. A relative density of 87 % of the theoretical density was achieved after a 3-h-long ...
Return of the forgotten nightmare: Bordetella pertussis uses a more negative Gibbs energy of metabolism to outcompete its host organism
(Elsevier B.V., 2024)
Pertussis (whooping cough) has been nearly eradicated during the 20th century, first of all due to an organized and comprehensive vaccination campaign that lasted for decades. Generations of doctors educated in Serbia (and ...
Plasma surface modification of textiles for application of natural dyes
(Woodhead Publishing, 2024)
Generally, clothes are constructed from woven or knitted fabrics, which can be made from natural or synthetic fibers or their mixtures. Natural fibers are characterized by their hydrophilicity, antistatic properties, and ...
The Application of Protein Concentrate Obtained from Green Leaf Biomass in Structuring Nanofibers for Delivery of Vitamin B12
(MDPI, 2024)
Nanofibers made of natural proteins have caught the increasing attention of food scientists because of their edibility, renewability, and possibility for various applications. The objective of this study was to prepare ...
Determination of the ductile-to-brittle transition temperature of NIOMOL 490 K steel welded joints
(Elsevier B.V., 06-2024)
This paper is dedicated to the ductile–brittle transition behaviour of the microalloyed structural steel NIOMOL 490 K. This steel grade is used for welded pressure vessels subjected to dynamic loads and operating at sub-zero ...
