Application of image analysis for cavitation erosion resistance monitoring of some engineering materials
(Bor : University of Belgrade, Technical Faculty, 2023)
Engineering materials are often used in various operating conditions including high temperatures,
pressure, aggressive solutions, or cavitation erosion. The phenomenon of cavitation erosion is expected
when fluid flow ...
Eco-friendly technology for gel-coat and fireproofing material production using bio-renewable and waste materials
(OOO «Centr «AЮMЭLЬ», 2020)
Innovative technology has been developed for the production of gelcoat and materials of reduced flammability based on unsaturated polyester resins. These materials were synthesized from raw materials obtained from waste ...
Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity ...
Multi-level Design and Selection of Optimum Working Fluids and ORC Systems for Power and Heat Cogeneration from Low Enthalpy Renewable Sources
(Elsevier Science Bv, Amsterdam, 2012)
This work presents a multi-level method for the design and selection of heat exchange working fluids tailored for Organic Rankine Cycle (ORC) systems used in power and/or heat cogeneration from renewable, low enthalpy ...
Asymmetric hydrogel membranes for heavy metal adsorption
(Belgrade : Institute of Technical Sciences of SASA, 2013)
Hydrogels containing strong acid groups have been used in the past for the removal of heavy metals. Unfortunately such hydrogels exhibit poor mechanical properties and are generally difficult to handle. In this work we ...
Geopolymer materials based on the electric arc furnace slag
(Belgrade : Materials Research Society of Serbia, 2013)
The remelting of iron and steel scrap in the electric arc furnaces generates the non-hazardous waste – electric arc furnace slag (EAFS), which can be disposed of to appropriate landfills. Currently, this slag found its ...
Homogeneous-heterogeneous catalytic effect of CaO · ZnO/K2CO3 during biodiesel synthesis
(Czech Society of Chemical Engineering, 2014)
The influence of thin benzoate-doped polyaniline coatings on corrosion protection of mild steel in different environments
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2013)
The corrosion process of mild steel in the presence of benzoate-doped polyaniline coatings exposed to 3% NaCl has been investigated. This system was also tested for cathodic protection and it has proven more efficient ...
Electrochemical determination of ascorbic acid using electrochemically deposited polyaniline
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2014)
Electroconducting polymers are promising materials to be used in various fields including: batteries, capacitors, electronic devices, corrosion, biosensors and sensors[1,6]. Polyaniline is probably the most investigated ...
Comparative Microhardness Analysis of Various Thin Metallic Multilayer Composite Films
(IEEE, New York, 2012)
Different composite systems of electrodeposited monolayered and multilayered thin metal films of Ni and Cu on cold-rolled copper substrates were made. Thin metal layers were deposited at narrow spacing of 300 nm and 150 ...
