Characteristics of the citrate-based zinc-polyaniline secondary cell with supercapattery behaviour
(Srpsko hemijsko društvo, Beograd, 2019)
The electrochemical characteristics of zinc-polyaniline (PANI) secondary cell in the electrolyte containing 0.8 M Na citrate, 0.3 M NH4Cl and 0.3 M ZnCl2 is investigated. Based on the measurements of potentials and voltage ...
N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study
(Elsevier, Amsterdam, 2019)
The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was ...
Sjenica, a newly identified radon priority area in Serbia, and radon data correlated with geological parameters using the multiple linear regression model
(North Univ Baia Mare, Baia Mare, 2019)
The paper deals with the analysis of the annual indoor radon concentrations variations due to different geological parameters of Sjenica community, Western Serbia. The measured Rn-222 concentrations were ranging from 10 ...
On the synthesis of 3-cyano-6-hydroxy-4-methyl-2-pyridone at room temperature / O sintezi 3-cijano-6-hidroksi-4-metil-2-piridona na sobnoj temperaturi
(Engineering Society for Corrosion, Belgrade, Serbia, 2019)
Milling of cyanoacetamide and acetoacetic ester as reactants, in the presence of KOH as the catalyst and ethanol as a viscous control agent (VCA) was performed in a planetary ball mill with the goal of investigating the ...
The effect of bacterial isolates from rhizosphere soils on wheat and barley seed germination / Uticaj bakterijskih izolata iz zemljišta rizosfere na indukciju klijavosti semena pšenice i ječma
(Serbian Soil Science Society, Belgrade, 2019)
Soil microorganisms, which are usually found in plant rhizosphere, have a wide spectrum of beneficial effects on the promotion of plant growth. The most comprehensively studied bacteria with these effects belong to the ...
Enhanced sorption of Cu2+ from sulfate solutions onto modified electric arc furnace slag
(Elsevier Science Bv, Amsterdam, 2019)
Pristine electric arc furnace slag (EAFS) as well as EAFS modified by alkali activation i.e. alkali activated slag (AAS) have found a novel application as adsorbents used in Cu2+ removal from sulfate solutions. The adsorption ...
Effects of different mechanical treatments on structural changes of lignocellulosic waste biomass and subsequent Cu(II) removal kinetics
(Elsevier, Amsterdam, 2019)
In this paper, the character of structural changes induced by different mechanical treatments to Prunus persica stones (PSs), and its subsequent effect on biosorption kinetics of Cu(II) were investigated. PSs were processed ...
Integrity assessment of reverse engineered ti-6al-4v eli total hip replacement implant
(Society for Structural Integrity and Life, Institute for Material Testing, 2019)
Total hip replacement implants are used as an artificial replacement for disfunctional hips in order to sustain joint movement. Chosen material and design of total hip replacement are the most influential factors for ...
Hardness and assessment of adhesion of monolayer and multilayer nickel thin films electrochemically deposited on silicon substrates with and without the ultrasonic agitation / Tvrdoća i procena adhezije jednoslojnih i višeslojnih tankih filmova nikla elektrohemijski deponovanih na silicijumskim podlogama sa i bez ultrazvučnog mešanja
(Academy of Criminalistic and Police Studies, Belgrade, 2019)
Composite systems of monolayer and multilayer nickel films electrochemically deposited on single crystal (100)-oriented silicon wafers were fabricated with and without the ultrasonic agitation. The hardness and adhesion ...
Washing and Desinfection of the Wells Type Reni / Hiperdezinfekcija bunara za vodosnabdevanje tipa Reni
(Čačak : Univerzitet u Kragujevcu, Agronomski fakultet, 2019)
We show in this work the treatment procedure utilized for cleaning and desnfection of water in water wells of large capacity as in the case of wells of Belgrade Waterworks. The typical examples of such well of large capacity ...
