Effect of the Modified Silica Nanofiller on the Mechanical Properties of Unsaturated Polyester Resins Based on Recycled Polyethylene Terephthalate
(Wiley, Hoboken, 2017)
Unsaturated polyester resin (UPe)-based nanocomposites and fumed silica Aerosil R812S, R805 and R816, and R200 modified with phenyl terminal group, R200NPh, were prepared. UPe resins were synthesized from maleic anhydride ...
Phase equilibrium data for the hydrogen sulphide + methane system at temperatures from 186 to 313 K and pressures up to about 14 MPa
(Elsevier, 2014)
Isothermal vapour–liquid equilibrium data have been measured for the methane–hydrogen sulphide (CH4 + H2S) binary system at five temperatures from 186.25 to 313.08 K, and pressures between 0.043 and 13.182 MPa. The ...
Molecular interpretation of low-temperature heat capacity of aliphatic oligo-urethane
(Elsevier, 2017)
The low-temperature heat capacity of semi-crystalline aliphatic oligo-urethane obtained from the reaction between butane-1,4-diol and hexamethylene 1,6-diisocyanate was measured using a Quantum Design PPMS (Physical Property ...
Laws of evolution parallel the laws of thermodynamics
(Elsevier, 2018)
We hypothesize that concepts from thermodynamics and statistical mechanics can be used to define summary statistics, similar to thermodynamic entropy, to summarize the convergence of processes driven by random inputs subject ...
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 ...
Sonophotocatalytic degradation of dye CI Acid Orange 7 by TiO2 and Ag nanoparticles immobilized on corona pretreated polypropylene non-woven fabric
(Elsevier, 2015)
This study discusses the possibility of using corona pre-treated polypropylene (PP) non-woven fabric as a support for immobilization of colloidal TiO2 and Ag nanoparticles in order to remove dye C.I. Acid Orange 7 from ...
First occurrence of rodingite in Central Serbia
(Carpathian-Balkan Geological Association, 2010)
During the field geological mapping and accompanied laboratory studies of the samples for the Basic Geological Map in the wider area of the town of Valjevo (Central Serbia) were distinguished serpentinites, gabbros, ...
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 ...
Exploitation of neglected horseradish peroxidase izoenzymes for dye decolorization
(Elsevier Sci Ltd, Oxford, 2015)
Horseradish peroxidase (HRP) is enzyme first described more than 200 years ago and yet there are still some aspects of this potent enzyme to be tackled. Researchers were focused on most abundant isoenzyme HRP CIA while ...
Zirconium dioxide nanopowders with incorporated Si4+ ions as efficient photocatalyst for degradation of trichlorophenol using simulated solar light.
(Amsterdam : Elsevier Science BV, 2016)
We present a hydrothermal method for synthesis of zirconia nanopowders: pure and with incorporated Si4+ ions. Zirconyl chloride and tetraethyl orthosilicate were used as precursors. As prepared powders were annealed at 600 ...
