Viability of newly developed process for catalytic conversion of bio-glicerin into various 'green chemical' and development opportunities for Serbia
(Institut za istraživanja i projektovanja u privredi, Beograd, 2016)
Crude bio-glycerin is a by-product in the production of biodiesel. An economically efficient valorization of crude bio-glycerin usually significantly defines the profitability of the biodiesel plant. A strong technological ...
Oscillators: Phenomenological mappings and analogies: Second part: Structural analogy and chains / Oscillateurs: Correspondance phénoménologiques et analogies: Deuxieme partie: Analogie structurale et les chaînes
(Belgrade, Serbia : Military Technical Institute, 2015)
New analytical and numerical results of dynamics for both linear and nonlinear system with two degrees of freedom are presented. For the mechanical chain system with two degrees of freedom, oscillations are investigated ...
Structural properties of Co, Ni and Mo powders obtained by electrochemical deposition
(Metalurgija, 2011)
Magnetic thin films based on iron group elements (Fe, Co, Ni) are currently used in computer's hard disk drives and in MEMS, whereas electrodeposition is a suitable method to obtain these materials. The powders of metals ...
Influence of welding current intensity on susceptibility to intergranular corrosion in welded joints of stainless steel / Uticaj jačine struje zavarivanja na sklonost prema interkristalnoj koroziji zavarenog spoja nerdajućeg čelika
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2017)
Susceptibility to intergranular corrosion in welded joints of austenitic stainless steel X5Cr-Ni18-10 was tested. The welding was performed with different intensity of welding current (110 A, 130 A and 150 A). The tests ...
Hardness and assessment of adhesion of monolayer and multilayer nickel thin films electrochemically deposited on silicon substrates with and without the ultrasonic agitation / Tvrdoća i procena adhezije jednoslojnih i višeslojnih tankih filmova nikla elektrohemijski deponovanih na silicijumskim podlogama sa i bez ultrazvučnog mešanja
(Belgrade : Academy of Criminalistic and Police Studies, 2019)
Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion ...
Application of polyaniline in corrosion protection of metals / Primena polianilina u zaštiti metala od korozije
(Belgrade, Serbia : Engineering Society for Corrosion, 2012)
Polyaniline is probably the most investigated electroconducting polymer. This popularity is a result of its important features: existence of various oxidation states, electrical and optical activity, low cost monomer, ...
Examination of phosphate ores bioleaching from Lisina deposit / Ispitivanje mogućnosti bioluženja fosfora iz fosfatne rude sa ležišta Lisina
(Belgrade, Serbia : Engineering Society for Corrosion, 2012)
Phosphorus solubilization from insoluble phosphate ores by acidophilic autotrophs and heterotrophs is a research of significant interest, because of potential use of these ores as fertilizers, which are economically and ...
Following the ecological and economic effects of mining and metallurgical landfills / Prateći ekološko-ekonomski efekti metalurških i rudarskih deponija
(Savez inženjera i tehničara Srbije, 2012)
In the process of refining raw materials and metal production in the metallurgical industry and mining are allocated a number of different secondary materials to be deposited. In the enrichment of the ore by flotation, in ...
Analysis of small series production with the development of new technologies / Analiza proizvodnje male serije sa razvojem novih tehnologija
(Savez inženjera i tehničara Srbije, 2012)
This paper presents the realized temperature transmitters. Transmitters were analyzed by technological generations. IHTM-CMTM in order to survive must develop new features and content of the product. Changes in technology ...
