Color stability of bulk-fill and universal composite restorations with dissimilar dentin replacement materials
(Wiley, Hoboken, 2019)
Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, ...
Influence of monomer and crosslinker molar ratio on the swelling behaviour of thermosensitive hydrogels / Uticaj molarnog odnosa monomera i umreživača na karakteristike bubrenja termoosetljivih hidrogelova
(Association of the Chemical Engineers of Serbia, 2012)
The synthesis of the poly(N-isopropylacrylamide-co-2-hydroxypropyl-methacrylate) hydrogel along with the analysis of the residual monomers content and influence of monomer and crosslinker molar ratios on the swelling ...
A study of the removal of copper ions from aqueous solution using clinoptilolite from Serbia
(Springer, New York, 2011)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not ...
An apparatus proposed for density measurements in compressed liquid regions at pressures of 0.1-60 MPa and temperatures of 288.15-413.15 K
(Srpsko hemijsko društvo, Beograd, 2015)
In this work, an apparatus for density measurements in the compressed liquid regions is presented. This installation is based on the use of a DMA HP density measuring cell and a DMA 5000 densimeter (both instruments are ...
Recovery of the damages of a welded steel structure of a coal-reloading bridge: Methodological approach
(Univerzitet u Novom Sadu - Fakultet tehničkih nauka, Novi Sad, 2012)
In present paper, the methodological approach to the analysis of the causes of failures and to recovery of the damages has been presented using, as an example, the fracture and damage of a welded steel structure of a ...
Life Expectancy Determination of Form-wound Coil Isolation of High-voltage Motor
(2016 IEEE International Power Modulator and High Voltage Conference (IPMHVC), 2016)
Isolation capability of organic and inorganic isolation materials is considerably different in respect to time. There is a relatively poor dependence on time in case of inorganic isolation materials. It is very significant ...
Nanoscale zerovalent iron (nZVI) supported by natural and acid-activated sepiolites: the effect of the nZVI/support ratio on the composite properties and Cd2+ adsorption
(Springer Heidelberg, Heidelberg, 2017)
Natural (SEP) and partially acid-activated (AAS) sepiolites were used to prepare composites with nanoscale zerovalent iron (nZVI) at different (SEP or AAS)/nZVI ratios in order to achieve the best nZVI dispersibility and ...
Densities and Derived Volumetric Properties of Ionic Liquids with [Nf(2)] and [NTf2] Anions at High Pressures
(Amer Chemical Soc, Washington, 2018)
The densities of four ionic liquids: 1-ethyl-3-methylimidazolium bis(fluorosulfonyl)imide ([E(3)Mim][Nf(2)]), n-propyl-n-methylpyrrolidinium bis(fluorosulfonyl)imide ([PMpyr][Nf(2)]), 1-butyl-l-methylpyrrolidinium ...
Utilization of supercritical carbon dioxide in fabrication of cellulose acetate films with anti-biofilm effects against Pseudomonas aeruginosa and Staphylococcus aureus
(Elsevier Science Bv, Amsterdam, 2018)
This study discusses utilization of supercritical carbon dioxide for impregnation of cellulose acetate films with thymol in order to produce material with anti-biofilm activity against Pseudomonas aeruginosa and Staphylococcus ...
The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
