Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
Preliminary data on the crystal-chemical characteristics of beryl from Cer Mt. (Serbia)
(Scientific Annals, School of Geology, Aristotle University of Thessaloniki, 2010)
A beryl crystal from Cer Mt. (Serbia) studied in this paper was characterized by means of
XRPD and wet-chemical analyses. It has following unit cell dimensions: a = 9.2166(8) Å, c = 9.192(1) Å, V = 676.2(1) Å3 and ratio ...
Flat band and photocatalytic activities of alumina/zirconia composite ceramics
(Srpsko keramičko društvo, 2022)
In the scope of this study mesoporous coupled alumina/zirconia composites were synthesized
via the sol-gel method, followed by heat treatment at 500°C, for 5h. The XRD pattern of
composites has shown that the addition ...

Synthesis, characterization and DFT calculations of Schiff base Co(III) complexes
(Materials Research Society of Serbia, 2022)
Two Co(III) complexes were synthesized and characterized by SCXRD, elemental analysis, IR, NMR and UV/Vis spectroscopy. DFT calculations were performed to elucidate the structures of Co(III)
complexes in solution.
Differences in infectivity and pathogenicity between Delta and Omicron strains of SARS-CoV-2 can be explained by Gibbs energies of binding and growth
(Vilnius, Lithuania : UAB "Kalanis", 2022)
During the COVID-19 pandemic, biothermodynamics has given its contribution to characterization
of viruses and research on energetics of processes performed by viruses [1-4]. Thermodynamic
properties represent the driving ...
The optimization of hydrothermally obtained hydroxyapatite deposition process on titanium by novel in-situ process
(Serbian Society of Corrosion and Materials Protection UISKOZAM, 2022)
Titanium and its alloys are widely used in medical devices, orthopedic implants, dental implants, and device components of aerospace industries. It is attractive for having superior room and elevated temperature mechanical ...
Spin states of Mn(II) and Fe(III) complexes with thiosemicarbazone
(Viena, Austria : Institute of Applied Synthetic Chemistry, TU WienChemIT e.U., 2023)
Mn(II) and Fe(III) complexes with condensation product of thiosemicarbazide and 2-acetylthiazole have been synthesized and characterized by single-crystal X-ray diffraction. Two complexes have the same ligand system – bis ...
Cold enzyme hydrolysis of starch
(Faculty of Chemistry, Serbian Biochemical Society, 2012)
With efforts to reduce global reliance on fossil fuels and lower the greenhouse gas emission, an increasing search for renewably sourced materials, which can be used as feedstock for biofuel production, is ongoing in the ...
Correlation between crystal orientation and morphology of silver powder particles obtained by different methods of synthesis and conditions of electrolysis / Uzajamna veza između orijentacije kristala i morfologije čestica praha srebra dobijenih različitim metoda sinteze i uslova elektrolize
(Belgrade, Serbia : Serbian Society of Corrosion and Materials Protection (UISKOZAM) / Beograd, Srbija : Udruženje inženjera Srbije za koroziju i zaštitu materijala (UISKOZAM), 2017)
Morphologies of silver powder particles obtained by chemical and electrochemical processes of
synthesis were correlated with their crystal structure. Reduction with hydrazine was used for the
synthesis of Ag powder by ...
