Gallic acid effect on the Briggs-Rauscher reaction dynamics
(Society of Physical Chemists of Serbia, 2018)
The effect of different concentration of gallic acid (GA) on the oscillatory behavior of the Briggs-Rauscher (BR) reaction is reported. In this work, the sample was injected before the start of oscillations. The main effect ...
Parožine (Charales, Characeae) Hrvatske / Stoneworts (Charales, Characeae) of Croatia
(Hrvatsko biološko društvo / Croatian Biological Society, 2018)
Parožine ili alge iz porodice Characeae složene su alge makroskopskog talusa koji izgledom
podsjeća na preslice. Uvrštene su na popis Natura 2000 staništa pod nazivom Tvrde oligo -
mezotrofne vode s dnom obraslim parožinama. ...
Binary oxide ceramics for enhanced phenols degradation under simulated Solar light
(Wiley, Hoboken, 2018)
Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM ...
Reuse of waste sulfur as a binding agent in concrete
(Association for Promotion of Holistic Approach to Environment, 2018)
Mainly due to the strict global environmental regulations regarding the oil and gas
refining processes, which limit the maximum quantity of sulfur in combustibles, the
availability of waste sulfur has been considerably ...
Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 catalyst
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
Kinetic modeling and optimization of sunflower oil methanolysis catalyzed by spherically-shaped CaO/gamma-Al2O3 particles were conducted in batch stirred and packed-bed tubular reactors at 60 degrees C. The proposed ...
Preparation and Properties of Short Oil Alkyd Resin/TiO2 Nanocomposites Based on Surface Modified TiO2 Nanoparticles
(Hoboken : Wiley, 2018)
Alkyd resin/TiO2 nanocomposites (NC) were prepared from short oil alkyd resin and TiO2 nanoparticles (NPs) surface modified with in situ formed imine ligand, based on 3,4-dihydroxybenzaldehyde and oleylamine, or with three ...
Possible use of ground sulfur as petroleum industry byproduct in self-compacting concrete production
(Association for Promotion of Holistic Approach to Environment, 2018)
The quantities of component materials used for production of concrete are high on the
global scale, therefore alternative materials are experimented on, in order to replace the
natural ones. The possibility of using ...
Adsorption kinetics of polyethersulfone membrane-supported hydrogels
(Hopkinton : Desalination Publications, 2018)
This study presents the route for preparation of the membrane-supporting materials with good mechanical behavior and adsorption properties that provide functionality and are easy to use in various environments. Polyethersulfone ...
Synthesis and properties of nano-hydroxyapatite/poly (methacrylic acid) composite hydrogels / Uticaj neutralizacije na svojstva poroznih hidrogelova na bazi hidroksiapatita i poli(metakrilne kiseline) sintetisanih slobodno-radikalskom polimerizacijom
(Beograd : Savez inženjera i tehničara Srbije, 2018)
Goals. The goal of this study was a development of biocompatible composite hydrogels, structurally similar to native bone tissue, by incorporation of ~60 wt % of calcium hydroxyapatite (HA) into a matrix of hydrogels. Also, ...
Technetium removal from the aqueous solution using zeolites A and Y containing transition metal ions Co2+ and Zn2+
(Dordrecht : Springer, 2018)
The adsorption properties of two zeolite types, faujasite (NaY, ZnY, CoY) and LTA-4A zeolite (NaA, ZnA, CoA), towards technetium were studied in batch static experiments. The Si/Al ratio, acidity, dealumination, chargebalance ...
