Thermodynamic and transport properties of biomass-derived furfural, furfuryl alcohol and their mixtures
(MDPI, 2021)
The limited reserves and well-known disadvantages of using fossil energy sources have increased the need for appropriate renewable substitutes in the production of various chemicals and materials. Biomass has been shown ...
Antibacterial activity of thymol/carvacrol and clinoptilolite composites prepared by supercritical solvent impregnation
(Journal of Porous Materials, 2021)
Novel composites based on natural zeolite-clinoptilolite and monoterpene phenols-thymol and carvacrol were prepared by supercritical solvent impregnation (SSI) in supercritical carbon dioxide (scCO(2)) at 30 MPa and 35 ...
Surface Patterning Increases Fluid Sorption Efficiency in Porous Reactive Coatings: A Model for Optimised Surface-Flow Filtration
(Transport in Porous Media, 2021)
A novel surface-flow filter has been designed to take advantage of a combination of both diffusion and lateral flow permeation, since active coatings, even if porous, tend to be far less permeable than through-flow constructs. ...
Hydroxyapatite/poly(vinyl alcohol)/chitosan coating with gentamicin for orthopedic implants
(Elsevier Ltd., 2023)
Electrophoretic deposition (EPD) was employed to fabricate composite coatings aimed for orthopedic implants. Hydroxyapatite (HAP), poly(vinyl alcohol) (PVA) and chitosan (CS) coatings, with or without antibiotic gentamicin ...
Characterization of the Ag43Cu37Zn20 alloy surface after potentiostatic polarization using LDI-TOF mass spectrometry
(Walter de Gruyter Gmbh, 2017)
This work is the first to demonstrate the possibilities of direct analysis of the corrosion film formed on Ag43Cu37Zn20 alloy using laser desorption/ionization (LDI) on a commercial matrix-assisted LDI time of flight mass ...
Enhanced photocatalytic degradation of RO16 dye using Ag modified ZnO nanopowders prepared by the solvothermal method
(Univerzitet u Novom Sadu - Tehnološki fakultet, Novi Sad, 2017)
In this work, Zn(CH3 COO)(2) 2 H-2 O with AgNO3 content from 0 to 6 mol% was solvothermally treated at 120 C for 18 h in the presence of poly(vinyl pyrrolidone), ethylene glycol and sodium hydroxide. The structural , ...
A new approach to compatibilization study of EVA/PMMA polymer blend used as an optical fibers adhesive: Mechanical, morphological and thermal properties
(Elsevier Sci Ltd, Oxford, 2018)
Mechanical, morphological and thermal properties of optical fiber adhesives, based on poly(ethylene-co-vinyl acetate) (EVA) with 18 and 40% of vinyl acetate, polymer blend of EVA/poly(methyl methacrylate) (PMMA), and graft ...
Influence of Different Pretreatments on the Antibacterial Properties of Chitosan Functionalized Viscose Fabric: TEMPO Oxidation and Coating with TEMPO Oxidized Cellulose Nanofibrils
(MDPI, Basel, 2019)
The main objective of this study was to obtain chitosan functionalized viscose fabric with improved antibacterial properties and washing durability. In this regard carboxyl and aldehyde groups, as binding points for ...
Galacto-oligosaccharide synthesis using chemically modified beta-galactosidase from Aspergillus oryzae immobilised onto macroporous amino resin
(Elsevier Sci Ltd, Oxford, 2016)
The goal of this study was to establish an efficient immobilisation protocol for beta-galactosidase from Aspergillus oryzae onto the polystyrenic macroporous resin Purolite (R) A-109 for better utilisation of its ...
Heat generation during plunge stage in friction stir welding
(Vinca Institute of Nuclear Sciences, 2013)
This paper deals with the heat generation in the Al alloy Al2024-T3 plate under different rotating speeds and plunge speeds during the plunge stage of friction stir welding. A 3-D finite element model is developed in the ...
