Modified eggshell catalyst for transesterification of sunflower oil: The effects of catalyst loading on FAMEs content
(Belgrade : Serbian Chemical Society, 2019)
Modified highly active CaO catalyst (ESCHC-600) derived from waste chicken eggshells were prepared and used in the transesterification of sunflower oil. Eggshells were subjected to calcination-hydration-calcination (CHC) ...
Bacterial diversity in typical abandoned multi-contaminated nonferrous metal(loid) tailings during natural attenuation
(Elsevier, 2019)
Abandoned nonferrous metal(loid) tailings sites are anthropogenic, and represent unique and extreme ecological niches for microbial communities. Tailings contain elevated and toxic content of metal(loid)s that had negative ...
Observations of the genus muelleria (bacillariophyceae) from the Republic of north Macedonia
(Belgique : Societe Royale de Botanique de Belgique, 2019)
Background and aims – An increased interest in the diatom flora from subaerial habitats in the Republic of North Macedonia has revealed the presence of a large number of interesting and often unknown, species. During a ...
Degradation of α-nitroso-β-naphthol by UVA-B activated peroxide, persulfate and monopersulfate oxidants in water
(Elsevier, 2019)
Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B ...
Non-toxic poly(vinyl alcohol)/clay composites as electrode material for detection of 4-chlorophenol and 4-nitrophenol
(Elsevier, 2019)
Development of new electrode materials is necessary for the fabrication of sensors with low detection limits, high sensitivity and broad concentration range. Beside analytical parameters, the ability to replace rare and ...

(10th European Symposium on Biopolymers, Straubing, Germany, September 25-27, 2019, Program Abstracts, 2019)
The aim of the present study is to optimize the synthesis of OSA-levan derivative.
The role of molecular properties of mononitrofluoranthenes to their mutagenic activity: Insight from ab initio and DFT calculations / Uloga molekulskih osobina mononitrofluorantena u njihovoj mutagenoj aktivnosti :AB initio i DFT pristup
(Serbia : Serbian Chemical Society, 2019)
The molecular properties of the environmental mutagens nitrofluoranthenes (NFs; 1-, 2-, 3-, 7- and 8-NF), such as (hyper)polarizability, dipole moment, molecular electrostatic potential (MEP), spectroscopic characteristics, ...
Nickel doped titanate catalysts for photocatalytic hydrogen generation
(Belgrade : Institute of Technical Sciences of SASA, 2019)
This study will focus on investigation of photocatalytic hydrogen production activity over low cost Ni modified titanates, as alternatives for highly cost and low-abundance noble metal based catalysts. The catalysts with ...
Microbially-induced deterioration of concrete from hydroelectric power plants – an initial study
(Balkan Environmental Association, 2019)
Microorganisms can grow on the surface of concrete and inside its pores and microcracks, producing different metabolites. Microbial metabolites, particularly acids, degrade concrete components and enhance its deterioration ...
