Designing of Synergistic Waste Mixtures for Multiphase Reactive Smelting
(MDPI, Basel, 2016)
Electric arc furnace (EAF) dust, together with a mill scale and coke were smelted in a laboratory electric arc furnace. These metallurgical wastes consist of a many different phases and elements, making the reaction process ...
Prediction of bed expansion of polydisperse quartz sand mixtures fluidized with water
(Elsevier Science Bv, Amsterdam, 2016)
In this paper, the minimum fluidization velocity and bed expansion of polydisperse sand mixtures fluidized with water were investigated. The fluidization experiments were carried out using 19 different fractions of quartz ...
Supercritical carbon dioxide extraction of Trigonella foenum-graecum L. seeds: Process optimization using response surface methodology
(Elsevier Science Bv, Amsterdam, 2016)
Pretreatment of fenugreek (Trigonella foenum-graecum L, Fabaceae) seeds was achieved using the step of defatting and acid hydrolysis. The obtained hydro-isolate (HI) was used as initial feed for diosgenin isolation by ...
Biofuel cell based on horseradish peroxidase immobilized on copper sulfide as anode for decolorization of anthraquinone AV109 dye
(Elsevier Science Bv, Amsterdam, 2016)
The potential application of electrochemically formed copper sulfide as horseradish peroxidase mediator in the enzymatic biofuel cell and anthraquinone AV109 dye as a fuel is investigated. The open circuit voltage of 0.52 ...
Volumetric and viscometric study with FT-IR analysis of binary systems with diethyl succinate and alcohols
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
Density, viscosity and refractive index of binary mixtures consisting of diethyl succinate + 1-propanol, or + 1-butanol, or + 1-hexanol have been measured at atmospheric pressure and over the temperature range from 288.15 ...
Supercritical and high pressure subcritical fluid extraction from Lemon balm (Melissa officinalis L., Lamiaceae)
(Elsevier, Amsterdam, 2016)
Analysis of yield and composition profile of Melissa officinalis (Lemon balm) extract obtained by two-step CO2 extraction at high pressure was analyzed. The first or essential oil fraction, collected at 10 MPa and 40 degrees ...
Optimization of supercritical CO2 extraction of fenugreek seed (Trigonella foenum-graecum L.) and calculating of extracts solubility
(Elsevier Science Bv, Amsterdam, 2016)
Supercritical CO2 (SC-CO2) extraction of fenugreek seeds (Trigonella foenum-graecum L, Fabaceae) was analyzed using different pressure and temperature (16.6-33.4 MPa and, 30-50 degrees C), which corresponded to SC-CO2 ...
Ordered mesoporous silica to enhance the bioavailability of poorly water-soluble drugs: Proof of concept in man
(Elsevier Science Bv, Amsterdam, 2016)
Formulating poorly water soluble drugs using ordered mesoporous silica materials is an emerging approach to tackle solubility-related bioavailability problems. The current study was conducted to assess the bioavailabilit ...
Wastes from bioethanol and beer productions as substrates for L(+) lactic acid production - A comparative
(Pergamon-Elsevier Science Ltd, Oxford, 2016)
Waste substrates from bioethanol and beer productions are cheap, abundant and renewable substrates for biorefinery production of lactic acid (LA) and variability in their chemical composition presents a challenge in their ...
The effect of graphene loading on mechanical, thermal and biological properties of poly(vinyl alcohol)/graphene nanocomposites
(Elsevier Science Inc, New York, 2016)
Poly(vinyl alcohol)/graphene (PVA/Gr) nanocomposite was synthesized with the aim of developing a novel improved material. The PVA/Gr nanocomposite was characterized by UV-visible spectroscopy, cyclic voltammetry, Raman ...
