Separation of phytochemicals from Helichrysum italicum: An analysis of different isolation techniques and biological activity of prepared extracts
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Helichrysum italicum presents a valuable source of natural bioactive compounds. In this work, a literature review of terpenes, phenolic compounds, and other less common phytochemicals from H. italicum with regard to ...
Improved HER activity of Ni and stainless steel electrodes activated by NiCoMo ionic activator - A combined DFT and experimental study
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
In this paper we discussed various factors contributing to the improvement of hydrogen evolution reaction (HER) activity of Ni and stainless steel electrodes activated by in situ addition of NiCoMo activators, using a ...
Effects of Catalyst Activity, Particle Size and Shape, and Process Conditions on Catalyst Effectiveness and Methane Selectivity for Fischer-Tropsch Reaction: A Modeling Study
(Amer Chemical Soc, Washington, 2017)
We investigate effects of catalyst activity, catalyst particle shape (sphere, slab, and hollow cylinder), size (i.e., diffusion length), catalyst distribution (uniform vs eggshell type distribution for a spherical particle), ...
Effect of sepiolite organomodification on the performance of PCL/sepiolite nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
Poly(epsilon-caprolactone) (PCL) based nanocomposites with unmodified and organomodified sepiolites were prepared by solution casting method. The sepiolites were modified with short (3-mercaptopropyl)trimethoxysilane ...
Towards understanding intermolecular interactions in hydantoin derivatives: the case of cycloalkane-5-spirohydantoins tethered with a halogenated benzyl moiety
(Royal Society of Chemistry, 2017)
A series of cycloalkane-5-spirohydantoins bearing a halogeno substituted benzyl group (X = Cl and Br) in position 3 has been synthesized and their structures (1-6) have been determined by a single crystal X-ray diffraction ...
Voltammetric behavior and determination of the macrolide antibiotics azithromycin, clarithromycin and roxithromycin at a renewable silver - amalgam film electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2017)
The renewable silver-amalgam film electrode (Hg(Ag)FE) was applied for voltammetric characterization and determination of semi-synthetic macrolide antibiotics azithromycin (AZI), clarithromycin (CLA) and roxithromycin (ROX) ...
Immobilization of Candida antarctica lipase B on kaolin and its application in synthesis of lipophilic antioxidants
(Elsevier Science Bv, Amsterdam, 2017)
Lipase B from Candida antarctica was immobilized by adsorption onto laboratory prepared metakaolin. This support has great potential for enzyme immobilization since it has good mechanical characteristics and thermal stability ...
Volumetric and viscometric properties of binary liquid mixtures as potential solvents for flue gas desulfurization processes
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Desulphurization processes (FGD) of flue gases from the thermal power and industrial plants, based on organic liquid solvents with mechanism of physical absorption (tetraethylene glycol dimethyl ether) or combination of ...
Supercapacitive Performances of Activated Highly Microporous Natural Carbon Macrofibers
(Electrochemical Soc Inc, Pennington, 2017)
Activated carbons with high specific surface area (even above 2000 m(2) g(-1)) and pronounced microporosity are prepared in two-stage process involving conventional carbonization of waste hemp fibers and subsequent activation ...
High pressure densities and derived thermodynamic properties for the (n-heptane plus n-octane plus ethanol) ternary system
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
The density of the ternary system (n-heptane + n-octane + ethanol) at temperatures from (293.15 to 373.15) K and at pressures from (0.1 to 40) MPa was experimentally determined at twelve compositions and the results are ...
