Thermal and rheological properties of unsaturated polyester resins-based composites
(Unsaturated Polyester Resins: Fundamentals, Design, Fabrication, and Applications, 2019)
Unsaturated polyester resins (UPR) are among the most commercially important thermosetting matrix materials for composites. This chapter summarizes the importance of the thermal and rheological properties of UPR. The ...
Optical properties CaWO4:Nd3+/PMMA composite layered structures
(Elsevier, Amsterdam, 2019)
In this article, we report characterization of the layered composite fabricated from Nd3+ doped calcium twigstate single crystal (CaWO4 :Nd3+) and poly(methyl methacrylate) - PMMA with various organic-inorganic interfaces: ...
Framework of new landfill GHG policy in developing countries: Case study of Serbia
(Wiley Periodicals, Inc, San Francisco, 2019)
This paper deals with greenhouse gas (GHG) emissions originating from changes in the waste sector in developing and transitional economies. Using a Serbian case study, the effects of different waste disposal techniques on ...
Assessment of sampling and chemical analysis of waste printed circuit boards from weee: gold content determination
(Savez inženjera metalurgije Srbije, Beograd, 2019)
Waste printed circuit boards (WPCBs) from discarded mobile phones and smartphones are considerably heterogeneous materials with a high gold content (approx. 490 grams per ton). The aim of our chemical analysis of samples ...
Optimization and kinetic modeling of waste lard methanolysis in a continuous reciprocating plate reactor
(Chemical Industry Press Co Ltd, Beijing, 2019)
Continuous biodiesel production from a waste pig-roasting lard, methanol and KOH was carried out in a reciprocating plate reactor (RPR) using a factorial design containing three process factors, namely methanol/lard molar ...
Fluorescence analysis of liposomal membranes permeability / Fluorimetrijska analiza permeabilnosti lipozomalnih membrana
(Savez inženjera i tehničara Srbije, Beograd, 2019)
The present study provides insight into changes in the liposomal membrane fluidity as a result of variation of structural components (two types of standard phospholipids - 1,2-dipalmitoyl-sn-glycerero3-phosphocholine, i.e. ...
PVA Cryogel as model hydrogel for iontophoretic transdermal drug delivery investigations. Comparison with PAA/PVA and PAA/PVP interpenetrating networks
(Elsevier, Amsterdam, 2019)
The use of polyvinyl alcohol (PVA) cryogel as a model hydrogel for iontophoretic transdermal investigations is proposed. Due to the excellent combination of its properties, it could be used for evaluating iontophoretic ...
IR/Raman characterization of Au-mercaptotriazole crystals
(Bulgarian Academy of Sciences, 2019)
The aim of this study was a characterization of the crystals of gold complexes based on mercaptotrazole, obtained from solutions with different pH values (2, 4, 7, and 9), using the methods of infrared (IR) and Raman ...
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 ...
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 ...
