Electrochemical synthesis and characterization of poly(o-toluidine) as high energy storage material
(Elsevier Ltd, 2019)
Poly(o-toluidine) (POT) is electrochemically synthesized on graphite electrode at constant current density of 1.5 mA cm−2 from aqueous electrolyte of 1.0 mol dm−3 H2SO4 and 0.25 mol dm−3 o-toluidine. Electrochemical ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Elsevier Ltd, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
Thermal analysis of polylactic acid under high CO2 pressure applied in supercritical impregnation and foaming process design
(Elsevier B.V., 2019)
Thermal properties of extrusion and injection grade polylactic acid (PLA) were analysed using high pressure differential scanning calorimetry (HP-DSC) under CO2 pressures of up to 50 MPa. The greatest depression of melting ...
Characterisation of peppermint (Mentha piperita L.) essential oil encapsulates
(Taylor and Francis Ltd, 2019)
The aim was to choose the optimal encapsulation system and to incorporate encapsulates loaded with essential oil into the ice cream as a model food product. Methods: Ca-alginate beads were produced by electrostatic extrusion ...
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 ...
A new kinetic model for the common juniper essenstial oil extraction by microwave hydrodistillation
(Chemical Industry Press, 2019)
The main objective of the present study was to model the kinetics of essential oil extraction from swelled ground juniper berries by classic hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD). A new ...
Fabrication and applications of multifunctional nanostructured TiO2
(Belgrade : Faculty of Agriculture, Department for Agricultural Engineering, 2017)
Nanomaterials development is a rapidly emerging field of research with enormous potential for societal and economic benefits. In agro and food industries dimension-dependent properties or phenomena of nanomaterials may be ...
Thermodynamic characterization of binary mixtures of poly(propylene glycol) 425 with toluene and o-, m- and p-xylenes
(Academic Press Ltd- Elsevier Science Ltd, London, 2019)
Density rho, viscosity eta and refractive index n(D) have been experimentally measured for four binary mixtures of poly(propylene glycol) of average molecular weight 425 + toluene/o-xylene/m-xylene/p-xylene over the ...
“Ship in a bottle” complexes as precursors for preparing nano-oxide materials
(16th International Zeolite Conference joint with the 7th International Mesostructured Materials Symposium (Abstracts), 2010)
Amine nickel(II) complexes can exhibit not only unique structural-directing role in the crystallization of open-framework aluminophosphate lattice but also act as precursors for obtaining very fine nano-oxide particles. ...
Heat transfer by liquid convection in particulate fluidized beds / ПРЕНОС ТОПЛОТЕ КОНВЕКТИВНИМ МЕХАНИЗМОМ У ПАРТИКУЛАТИВНО ФЛУИДИЗОВАНОМ СЛОЈУ
(Serbian Chemical Society, 2022)
In this work the theoretical model for heat transfer from a wall to a
liquid-solid fluidized bed by liquid convective mechanism has been proposed.
The model is based on thickness of boundary layer and film theory. The ...
