Elektrohemijsko ponašanje 4-nitrofenola na modifikovanoj elektrodi od staklastog ugljenika / Electrochemical behavior of 4-nitrophenol on modified glassy carbon electrode
(Универзитет у Београду, Хемијски факултет, 2014)
U sklopu ove doktorske disertacije proučavana je elektrohemijska oksidacija 4-nitrofenola na modifikovanoj elektrodi od staklastog ugljenika (Glassy CarbonElectrode – GCE). Za modifikaciju GCE korišćene su natrijumski ...
AC Impedance tracking of glassy carbon activation
(Serbian Chemical Society, Belgrade, 2010)
Carbon materials, due to their physical and chemical properties, have found wide application in different electrochemical systems. They are often used as substrates for supercapacitors and different types of electrocatalysts. ...
Platinum electrocatalyst supported on glassy carbon: a dynamic response analysis of Pt activity promoted by substrate anodization
(The Royal Society of Chemistry, 2014)
In previous investigations the physicochemical state of electrochemically activated glassy carbon (GC) has been found to affect the electrochemical activity of GC-supported Pt particles. It has been assumed that carbon ...
Formation Of Hydroquinone And Catechol During Electrooxidation Of Phenol On Clay-Modified Electrodes
(Society of Physical Chemists of Serbia, 2016)
Clay was modified by pillaring, which was performed by combinations of pillaring cations: Al3+ and Fe3+ or Al3+, Fe3+ and Ni2+. The synthesized materials were used to obtain glassy carbon electrode (GCE) coatings. ...
Visualisation of the interaction between Acidithiobacillus ferrooxidans and oil shale by atomic force microscopy
(Technical Faculty, Bor-Serbia, Bor, 2012)
This study visually documents the mechanical contact and interaction between the bacterial cells of two biogeocenotically different strains of Acidithiobacillus ferrooxidans (At. ferrooxidans) and oil shale containing ...
Band-stop filter with suppression of requested number of spurious stopbands
(Cambridge Univ Press, Cambridge, 2017)
Design method for band-stop filters (BSFs) that suppress a requested number of spurious bandstops and reduce ripples in the passbands below similar to 1 dB is proposed. BSF is designed in a form of a cascade of cells, each ...
Alumina production from purified Bayer liquor / Proizvodnja glinice iz pročišćene Bayerove otopine
(Hrvatska: Hrvatsko društvo kemijskih inženjera i tehnologa
(HDKI), 2019)
Removal of some impurities from Bayer liquor, such as zinc compounds, allows obtaining alumina with low content of impurities incorporated in the crystalline structure. Impurities in alumina influence the quality of products ...
CO2 conversion enhancement in a periodically operated Sabatier reactor: Nonlinear frequency response analysis and simulation- based Study
(The 25th International Symposium of Chemical Reaction Engineering (ISCRE 25), Florance, Italy, 2018)
Nonlinear frequency response (NFR) analysis was applied on a Sabatier reactor. A substantial improvement in CO2 conversion was predicted under certain conditions. The NFR analysis prediction was validated using a kinetic ...
Predikcija brzine vetra na teritoriji Libije primenom veštačkih neuronskih mreža
(Univerzitet u Beogradu - Mašinski fakultet, 2018)
Libija je zemlja bogata naftom i prirodnim gasom čije učešće u proizvodnji električne energije je preko 90%.
Međutim, sve više su u upotrebi i obnovljivi izvori energije, kao što je energija vetra. U Libiji postoji ...
