Experimental measurements of thermophysical properties and theoretical quantum chemical calculations of alcohol and hydrocarbon binary systems
(IFP Energies nouvelles, 2021)
Insight in different types of mixtures’ behavior (such as volumetric and transport
properties, and related excess properties) has high importance [1]. These properties depend on the intermolecular interactions between ...
State-of-the-Art of Eggshell Waste in Materials Science: Recent Advances in Catalysis, Pharmaceutical Applications, and Mechanochemistry
(Frontiers Media S.A., 2021)
Eggshell waste is among the most abundant waste materials coming from food processing technologies. Despite the unique properties that both its components (eggshell, ES, and eggshell membrane, ESM) possess, it is very often ...
Aerogel Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 catalysts for hydrodesulphurisation of dibenzothiophene and 4,6-dimethyldibenzothiophene
(Elsevier, 2021)
Re/Pd-TiO2/SiO2 and Co/Mo-Al2O3/SiO2 aerogel catalysts were synthesized using sol-gel method and supercritical drying in excess solvent, and investigated in the hydrodesulphurisation (HDS) of dibenzothiophene (DBT) and ...
Controlling Pd-Catalyzed N-Arylation and Dimroth Rearrangement in the Synthesis of N,1-Diaryl-1H-tetrazol-5-amines
(American Chemical Society (ACS), 2021)
The Pd-catalyzed N-arylation method for the synthesis of eighteen N,1-diaryl-1H-tetrazol-5-amine derivatives is reported. By running the reactions at 35 °C, compounds were isolated as single isomers since the undesired ...

Ovo tehničko rešenje se odnosi na rešavanje problema prečišćavanja industrijskih i podzemnih voda kontaminiranih naftnim zagađivačima. Ono daje prikaz kombinovane tehnike prečišćavanja voda kontaminiranih naftnim ugljovodonicima ...
Phytochemicals from bryophytes: Structures and biological activity / Фитохемикалије из бриофита: структура и биолошке активности
(Serbian Chemical Society, 2021)
Little attention has been paid to the bryophytes as sources for human diet despite the presence of 23,000 species in the world. Some mosses contain Vitamin B1, tocopherols, prostaglandin-like highly unsaturated fatty acids ...
Geochemistry of water and sediment
(MDPI, 2021)
Access to drinking water is one of the largest problems of modern times, and water
pollution is a growing problem worldwide. Increased concentrations of different toxic
substances, especially heavy metals, affect ...
Stochastic method for prediction of subsidence due to the underground coal mining integrated with GIS, a case study in Serbia
(Springer Nature Switzerland AG, 2021)
The problem of subsidence and damages on buildings above mining works is an inevitable consequence of underground coal
mining in large mining basins. Significant development of various methods for prediction of the ...
High pressure densities of ethylene glycol and caffeine mixtures
(IFP Energies nouvelles, 2021)
Ethylene glycol is a well-known fluid that is recognized for its application in heat transfer processes [1]. In order to improve its characteristics and performances, adding other particles in the mixture of ethylene glycol ...
Assessment of hot-melt coating methods for multiparticulate substrates: Mortar-coating vs. pan-coating / Procena metoda za oblaganje višečestičnih supstrata topljenjem: oblaganje u pateni vs. oblaganje u bubnju
(Serbia : Pharmaceutical Association of Serbia, 2021)
Hot-melt coating (HMC) is an alternative, solvent-free coating method generally used to modify substrate release rate and/or mask its unpleasant taste. The aim of this study was to assess two HMC methods (pan-coating and ...
