Synthesis and characterization of new cerium doped phosphate tungsten bronze
(Society of Physical Chemists of Serbia, 2021)
Cerium doped phosphate tungsten bronze (Ce-PWB) was synthetized by phase transformations of CePW12O40x6H2O (Ce-6-PWA) salt. The solid-solid transformations of Keggin's anion of this salt, including dehydration processes ...
Corroded medieval iron nail from the Studenica Monastery - Material analysis and laser cleaning
(Elsevier, 2024)
In this paper, the state of an archaeological artefact (iron nail) originating from the Studenica Monastery (Serbia) has been presented as well as the possibility of laser cleaning its corrosion layers. To determine the ...
Electrochemical oxidation of 2,4,6-trichlorophenol on iron-doped nanozirconia cerami / Elektrohemijska oksidacija 2,4,6-trihlorfenola na nano-cirkonijum - oksidnoj matrici dopiranoj gvožđem
(Beograd: Srpsko hemijsko društvo, 2021)
Solvothermaly synthesized zirconium oxide nanopowders, pure and
doped with various amounts of iron ions (1–20 %), were used as modifiers of
glassy carbon electrodes. The modified electrodes were tested in the reaction ...

The focus of this research is a techno-philosophical and praxeologycal analysis of issues into field of design in relationship to connection of ideas, discourses and values of classical and contemporary approaches to ...
Visuality, method, and Laban’s ortography: one parallel
(Belgrade : The Academy of Applied Technical Studies "Belgrade", 2023)
Sources of inspiration for the formation of authentic orthographic and methodological systems are a challenge for researching the emergence and logic of constituting visual opinion. In this paper, one of the possible ...
Immobilization of α-amylase from bacillus paralicheniformis on bentonites
(The Society of Physical Chemists of Serbia, 2022)
α-Amylase from Bacillus paralicheniformis (BliAmy) is a highly efficient raw starch digesting enzyme. Starch is an inexpensive source of many food industrial products. Naturally occurring clay are non-toxic, environmentally ...
