Ultrasonic assisted arsenate adsorption on solvothermally synthesized calcite modified by goethite, alpha-MnO2 and goethite/alpha-MnO2
(Elsevier, Amsterdam, 2014)
A highly porous calcium carbonate (calcite; sorbent 1) was used as a support for modification with alpha-FeOOH (calcite/goethite; sorbent 2), alpha-MnO2 (calcite/alpha-MnO2; sorbent 3) and alpha-FeOOH/alpha-MnO2 ...
Impermeable layers in landfill design / Prilog projektovanju vodonepropusnih slojeva deponija
(Association of Chemical Engineers of Serbia, 2013)
Landfills are complex systems that could potentially contaminate the environment. This needs to be prevented by providing impermeability during the landfill design. In this aim, the related regulations should be followed ...
Voltammetric and Quantum Investigation of Selected Succinimides
(Electrochemical Science Group, Beograd, 2018)
A series of succinimide derivatives were studied using the cyclic and square wave voltammetry. Density function theory was used in order to determinate which of the structural parameters influence the electrochemical ...
Sol-gel Synthesis of Anatase Nanopowders for Efficient Photocatalytic Degradation of Herbicide Clomazone in Aqueous Media
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M ...
Organic Rankine Cycle system performance targeting and design for multiple heat sources with simultaneous working fluid selection
(Elsevier Sci Ltd, Oxford, 2017)
This work presents a systematic approach toward the design of Organic Rankine Cycles (ORC) for the generation of power from multiple heat sources available at different temperature levels. The design problem is approached ...
Effect of surface modified TiO2 nanoparticles on thermal, barrier and mechanical properties of long oil alkyd resin-based coatings
(Budapest Univ Technol & Econ, Budapest, 2015)
Novel soy alkyd-based nanocomposites (NCs) were prepared using TiO2 nanoparticles (NPs) surface modified with different gallates, and for the first time with imine obtained from 3,4-dihydroxybenzaldehyde and oleylamine ...
