sigma-Hole Interactions of Covalently-Bonded Nitrogen, Phosphorus and Arsenic: A Survey of Crystal Structures
(MDPI, 2014)
Covalently-bonded atoms of Groups IV-VII tend to have anisotropic charge distributions, the electronic densities being less on the extensions of the bonds (sigma-holes) than in the intervening regions. These sigma-holes ...
Economizer water-wall damages initiated by feedwater impurities
(Association of Chemical Engineers of Serbia, 2014)
The main causes of efficiency loss in thermal power plants are boiler tube failures that diminish unit reliability and availability, and raise the cost of the electric energy. For that reason, the regular examination of ...
Investigation of key interactions between the second extracellular loop of the dopamine D2 receptor and several hydroxy-N-{[2-(4-phenylpiperazin-1-yl)ethyl]phenyl}nicotinamides
(Serbian Chemical Soc, Belgrade, 2014)
The dopaminergic receptor system has been the focus for the development of new pharmacotherapeutic agents targeting a number of central nervous system related disorders, such as drug addiction, schizophrenia, depression, ...
Polysaccharides of higher fungi: biological role, structure and antioxidative activity
(Association of Chemical Engineers of Serbia, 2014)
The fungal polysaccharides attract a lot of attention due to their multiple challenging biological properties, such as: anti-tumor, anti-viral, anticomplementary, anticoagulant, hypolipidemic, immunomodulatory and ...
Technological investigations of sulphide oxidation from flotation tailings in order to increase the degree of copper leaching
(Institut za rudarstvo i metalurgiju Bor, 2014)
The off-balance resources present the environmental problem and potential resource for copper extraction. This paper presents the results obtained using different reagents for the process of sulphide form oxidation of ...
Effect of supporting electrolyte on electrolytic degradation of cyanide wastewater / Uticaj hloridnih jona na elektrohemijsku oksidaciju cijanida u otpadnim vodama
(Belgrade, Serbia : Engineering Society for Corrosion, 2014)
The paper describes the influence of chloride ions on the electrochemical oxidation of cyanide from wastewater. Chloride ions are added in the form of NaCl (c=0.017 mol/L), and electrochemical oxidation is carried out in ...
Corrosion properties of an aluminium alloy 7000 series after a new two step precipitation hardening / Otpornost prema koroziji aluminijumske legure serije 7000 posle novog dvostepenog termičkog taloženja
(Belgrade, Serbia : Engineering Society for Corrosion, 2014)
Corrosion properties of an aluminium alloy 7000 series were investigated by different electrochemical methods. The alloy was subjected to the one-step and to a new two-step precipitation hardening. Polarization measurements ...
Electrochemical Removal of Microorganisms in Drinking Water
(Electrochemical Science Group, 2014)
It is known that silver, even in small concentrations (hundred parts of milligrams per liter), has the ability to destroy microorganisms, i.e. it has strong bactericidal abilities. Cleansing vast amount of water using ...
Diastereoselective addition of alkenylchromium(III) reagents to Garner's aldehyde. The Nozaki-Hiyama-Kishi coupling approach to sphingosines and ceramides
(Serbian Chemical Soc, Belgrade, 2014)
Intermolecular Nozaki-Hiyama-Kishi coupling between alkenylchromium(III) reagents, derived from either (E)-(2-bromoethenyl)benzene or (E)-1-iodo-1-pentadecene, and the conformationally rigid Garner's aldehyde resulted in ...
The assessment and distribution of heavy metals in surface sediments from the reservoir 'Barje': Serbia / Procena sadržaja i raspodele teških metala u površinskom sedimentu akumulacije 'Barje' - Srbija
(Savremene tehnologije, 2014)
In this study, the nature of the association of heavy metals (Fe, Co, Ni, Cu, Cd, Pb, Mn, and Zn) in sediments of the recent reservoir 'Barje' (Leskovac, Serbia) was investigated. The aim was to make the identification of ...
