The influence of thermodynamic parameters on alkaline activators of geopolymers and the structure of geopolymers
(Macedonian Journal of Chemistry and Chemical Engineering, 2021)
Thermodynamic parameters (densities, viscosities, speed of sound, and refractive index) of four series of alkaline activators were determined over the temperature range from 15 to 60 degrees C for the process of ...
High-temperature and high-pressure (p, rho, T) measurements and derived thermodynamic properties of 1-octyl-3-methylimidazolium hexafluorophosphate
(Srpsko hemijsko društvo, Beograd, 2020)
Densities of ionic liquid (IL) 1-octyl-3-methylimidazolium hexafluorophosphate [OMIM][PF6] at high temperatures and high pressures were measured. The measurements were made along 10 isotherms over a temperature range T = ...
Influence of gamma radiation on measurement fast pulse voltages by Kerr electro-optic effect
(Radiation Effects and Defects in Solids, 2021)
In this paper, the possibility of measuring the electronic pulse from an electronic generator for plasma heating by electro-optical method is considered. The experiments are performed by applying the Kerr effect on an ...
Viscoelasticity of multicellular systems caused by collective cell migration: dynamics at the biointerface
(Springer, New York, 2020)
Viscoelasticity of multicellular systems caused by collective cell migration depends on (1) viscoelasticity of migrating clusters, (2) viscoelasticity of surrounding resting cells and (3) the size, slip effects and thickness ...
Micromechanical analysis of fatigue and crack growth in carbon-fiber epoxy composites based on mechanical testing
(Savez hemijskih inženjera, Beograd, 2020)
The paper presents static and dynamic tests of carbon/epoxy composite materials with fiber orientation at 0 degrees/90 degrees and +/- 45 degrees. The main tensile properties were determined as a basis for subsequent dynamic ...
An analysis of impact testing of high strength low-alloy steels used in ship construction
(Brodogradnja, 2021)
Brittle damages have been examined widely since welding became common practice when it comes to carrying out robust structures. Welded structure of the ship hull has to be continuous. Brittle damages that occur on hull ...
Arsenic Removal from Water Using Industrial By-Products
(Hindawi Limited, 2013)
In this study, removal of arsenic ions using two industrial by-products as adsorbents is represented. Removal of As(III) and As(V) from water was carried out with industrial by-products: residual from the groundwater ...
A novel platinum-based nanocatalyst at a niobia-doped titania support for the hydrogen oxidation reaction
(Journal of the Serbian Chemical Society, 2011)
The kinetics of the hydrogen oxidation reaction (HOR) was studied at Pt nanoparticles supported on niobia-doped titania (Pt/N-T). The catalyst support, with the composition of 0.05NbO(2.5-delta)-0.995TiO(2) (0 LT delta LT ...
Improvement of production performance of functional fermented whey-based beverage / Unapređenje performansi proizvodnje funkcionalnog fermentisanog napitka na bazi surutke
(Association of the Chemical Engineers of Serbia, 2014)
The aim of this study was improvement of the performances for the production of whey-based beverages with highly productive strains of Lactobacillus. Individual or mixed cultures containing Lactobacillus helveticus ATCC ...
CFD analysis of exothermic reactions in al-au nano multi-layered foils
(Institute of Metals and Technology, 2011)
This work presents the possibility of numerical modelling using Computational Fluid Dynamics (CFD) in the field of nano-foils. The governing equations were solved using a Finite Volume Methodology (FVM). The computational ...
