Bioethanol production from triticale by simultaneous saccharification and fermentation with magnesium or calcium ions addition
(Elsevier Sci Ltd, Oxford, 2015)
The aim of this study was to determine the effect of magnesium or calcium ions content in triticale mashes on glucose and maltose content after liquefaction as well as on bioethanol yield after fermentation. Triticale ...
Novel and conventional working fluid mixtures for solar Rankine cycles: Performance assessment and multi-criteria selection
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
This work investigates the performance of working fluid mixtures for use in solar ORC (Organic Rankine Cycle systems) with heat storage employing FPC (Flat Plate Collectors). Several mixtures are considered including ...
Kinetics, thermodynamics, and structural investigations on the removal of Pb2+, Cd2+, and Zn2+ from multicomponent solutions onto natural and Fe(III)-modified zeolites
(Springer, New York, 2015)
The adsorption of Pb2+, Cd2+, and Zn2+ from equimolar multicomponent solutions onto natural and Fe(III)-modified zeolites was studied by batch experiments in order to determine the influence of the competitive effect on ...
Bond strength of restorative materials to hydroxyapatite inserts and dimensional changes of insert-containing restorations during polymerization
(Elsevier Sci Ltd, Oxford, 2015)
Objective. To determine the shear bond strength (SBS) between synthetic controlled porous hydroxyapatite (HAP) inserts and restorative materials and dimensional changes of insert-containing restorations during curing. ...
Graphene-based antibacterial composite coatings electrodeposited on titanium for biomedical applications
(Elsevier Science Sa, Lausanne, 2015)
The graphene based silver/hydroxyapatite/graphene (Ag/HAP/Gr) composite coatings were produced by electrophoretic deposition (EPD) on titanium to assemble porous bioactive homogenous coatings, with improved corrosion ...
A new electrolyte based on Tm3+-doped delta-Bi2O3-type phase with enhanced conductivity
(Elsevier Science Bv, Amsterdam, 2015)
The possibility to stabilize the delta-Bi2O3-type polymorph with high ionic conductivity by doping with Tm2O3 was investigated in this study. Five microaystalline samples were synthesized at 750 degrees C from alpha-Bi2O3 ...
Preparation of boron-doped hydrothermal carbon from glucose for carbon paste electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Boron doped hydrothermal carbon microspheres were synthesized by introducing boric acid into glucose precursor solution to obtain boron concentration from 0.1 to 1 wt. %. Following hydrothermal treatment, samples were ...
Optimisation of microwave-assisted extraction parameters for antioxidants from waste Achillea millefolium dust
(Elsevier Science Bv, Amsterdam, 2015)
Microwave-assisted extraction of polyphenols and flavonoids from waste Achillea millefolium (yarrow) dust was optimised using the response surface methodology. The influence of the extraction time (13-47 s), ethanol ...
