Accumulation of heavy metal(loid)s and polycyclic aromatic hydrocarbons in the sediment of the Prahovo Port (Danube) and associated risks
(Springer Science and Business Media Deutschland GmbH, 2023)
The current study investigated the concentrations, possible sources, toxicity, and ecological risk of eight heavy metal(loid)s (As, Cd, Cr, Cu, Hg, Ni, Pb, Zn) and sixteen priority polycyclic aromatic hydrocarbons (PAHs) ...
The Impact of Ca2+ on Intracellular Distribution of Hemoglobin in Human Erythrocytes
(MDPI AG, 2023)
The membrane-bound hemoglobin (Hb) fraction impacts red blood cell (RBC) rheology and metabolism. Therefore, Hb–RBC membrane interactions are precisely controlled. For instance, the signaling function of membrane-bound ...
Reaction microkinetic model of xylose dehydration to furfural over beta zeolite catalyst
(Springer Science and Business Media Deutschland GmbH, 2023)
In recent decades, there has been a growing interest in bio-refineries as a crucial element in transitioning to a low-carbon economy. One specific aspect of this interest is the conversion of carbohydrates into separate ...
Investigation on the Adsorption of the Carbamate Pesticide Methomyl from Aqueous Solution using Modified Co-Beta Zeolite Particles
(International Institute for the Science of Sintering (IISS), 2023)
Adsorption of carbamate pesticide Methomyl by Co-Beta Zeolite particles prepared by wet ion-exchange method from aqueous solutions was studied. The effect of zeolite and pesticide concentrations, pH value, and sintering ...
Biomedical Applications of Thermosensitive Hydrogels for Controlled/Modulated Piroxicam Delivery
(MDPI, 2023)
The objectives of this study are the synthesis of thermosensitive poly(N-isopropylacrylamide-co-2-hydroxypropyl methacrylate), p(NiPAm-HPMet), hydrogels and the analysis of a drug-delivery system based on piroxicam, as a ...
Influence of Raster Angle on Tensile Properties of FDM Additively Manufactured Plates made from Carbon Reinforced PET-G Material
(Belgrade : Association for ETRAN Society, 2023)
Tensile properties of thin plate specimens made from short carbon fiberreinforced PET-G material are experimentally evaluated for various raster angles(printing directions). In additive manufacturing (AM), raster angle is ...
Acrylic modified kraft lignin microspheres as novel support for immobilization of laccase from M.Thermophila expressed in A. oryzae (Novozym® 51003) and application in degradation of anthraquinone textile dyes
(Elsevier Ltd., 2023)
The novel lignin-based microspheres (LMS-DEGDMA) were produced through a two-step modification procedure consisting of kraft lignin (KL) modification with acrylic acid synthesized from fructose; and suspension and ...
Predicting Low-Modulus Biocompatible Titanium Alloys Using Machine Learning
(MDPI, 2023)
Titanium alloys have been present for decades as the main components for the production of various orthopedic and dental elements. However, modern times require titanium alloys with a low Young’s modulus, and without the ...
Influence of N doping on structural and photocatalytic properties of hydrothermally synthesized TiO2/carbon composites
(Journal of the Serbian Chemical Society, 2023)
Abstract: N-doped TiO2/carbon composites (TiO2/CN) with different nitrogen content, were obtained starting from titanium isopropoxide and glucose, and by varying the amount of melamine, added to starting reaction mixture. ...
Assessment of Life Quality in Children with Dysphonia Using Modified Pediatric Voice-Related Quality of Life Questionnaire in Serbia
(MDPI, 2023)
Background: Hoarseness is not uncommon in children, especially at school age, as communication with peers is intensified. It is caused by improper use or overuse of the vocal apparatus. (2) Methods: The study included 85 ...
