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 ...
"Do-It-Yourself" reliable pH-stat device by using open-source software, inexpensive hardware and available laboratory equipment
(Public Library Science, San Francisco, 2018)
In this paper, we present the construction of a reliable and inexpensive pH stat device, by using open-source "OpenPhControl" software, inexpensive hardware (a peristaltic and a syringe pump, Arduino, a step motor...), ...
Impact of Alumina Particles on the Morphology and Mechanics of Hybrid Wood Plastic Composite Materials
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2019)
Hybrid composite panels of Wood-Plastic Composites (WPC) consisting of wood and poly (methyl methacrylate) (PMMA) were reinforced with alumina particles and made by "hot pressing" method. Alumina-based particles were made ...
Synthesis, Structure and Properties of Nickel-Iron-Tungsten Alloy Electrodeposits PART II: Effect of Microstructure on Hardness, Electrical and Magnetic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2016)
Nanostructured nickel-iron-tungsten alloys were produced by electrodeposition from an ammoniacal citrate bath. The tungsten content of the alloy ranged from 0.8 wt.% to 11 wt.%, and the crystal grain size of the FCC phase ...
Hydrometallurgical recovery of tin and lead from waste printed circuit boards (wpcbs): limitations and opportunities
(Croatian Metallurgical Soc, Zagreb, 2016)
In this paper, possibility for selective Pb and Sn recovery, using three different solutions of NaOH, HCl and HNO3, from WPCBs containing low concentrations of Pb and Sn is presented. According to obtained results, over ...
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 ...
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 ...
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 , ...
Mechanical Properties of Biomass-derived Silica Nanoparticles Reinforced PMMA Composite Material
(Science of Sintering, 2022)
Rice husk was used to produce silica particles, which were then used to reinforce the polymer matrix. The synthesized SiO2 particles were characterized using X-ray diffraction, Fourier transforms infrared spectroscopy ...
Comparison of Mechanical Behavior of SiC Sintered Specimen to Analysis of Surface Defects
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Silicon carbide is the material that in sintered form is suiTab. for protection from impact as part of the multilayered structure. Its role is to accumulate energy from the projectile, to plastically deform the projectile ...
