Electrochemical behavior of different types of alumina
(Elsevier, 2021)
This work presents the investigation of electrochemical properties of three alumina samples with different structure and crystal water content. The samples were characterized by XRD and FTIR-ATR analysis, confirming the ...
The influence of silver content on antimicrobial activity and color of cotton fabrics functionalized with Ag nanoparticles
(Elsevier, 2009)
The aim of this study was to examine the antimicrobial efficiency and color changes of cotton fabrics
loaded with colloidal silver nanoparticles which were synthesized without using any stabilizer. The influence
of ...
There are two twin shadows, but Einstein is one!
(Society of Thermal Engineers of Serbia, 2012)
2011 is the international year of chemistry, and it is exactly 100 years past after the P. Langevin promotion of “twin paradox” problem. The hundred year old problem still demands its solution. Twin paradox, established ...
Superior photocatalytic properties of carbonized PANI/TiO2 nanocomposites
(Elsevier, 2017)
A simple bottom-up method for the preparation of novel and very efficient photocatalytic nanocomposite system based on carbonized form of polyaniline (PANI) and colloidal TiO2 nanocrystals has been developed. The carbonized ...
Strong and tough, pH sensible, interpenetrating network hydrogels based on gelatin and poly(methacrylic acid)
(Wiley, 2022)
Hydrogels are promising materials for biomedical applications due to highly hydrated, porous, permeable structure with possibility to accommodate living cells, drugs, or bioactive factors. In this paper, we reported ...
Partial purification and characterization of midgut leucyl aminopeptidase of Morimus funereus (Coleoptera : Cerambycidae) larvae
(Oxford : Pergamon-Elsevier Science Ltd, 2003)
Exopeptidases of Morimus funereus larvae were partially purified and characterized. Specific leucyl aminopeptidase (LAP) activity was increased eight-fold by gel filtration of the crude midgut extract. The partially purified ...
Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Beograd : Savez inženjera i tehničara Srbije, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
Chemical modification of chloroperoxidase for enhanced stability and activity
(Elsevier Sci Ltd, Oxford, 2014)
Chloroperoxidase from Caldariomyces fumago (CPO, EC 1.11.1.10) is one of the most interesting enzymes from the group of heme peroxidases and has been extensively applied in synthetic processes. Nevertheless, the practical ...
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 ...
