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), ...
Shaped Co2+ doped TiO2 nanocrystals synthesized from nanotubular precursor: Structure and ferromagnetic behavior
(Springeropen, London, 2017)
Co2+ doped TiO2 nanocrystals were synthetized by a hydrothermal treatment procedure applied to precursor dispersion of titania nanotubes and Co2+ ions. Mixture of polygonal and prolate spheroid-like nanocrystals was obtained. ...
Experimental and theoretical insight into the electronic properties of 4-aryl-5-arylazo-3-cyano-6-hydroxy-2-pyridone dyes
(Wiley, Hoboken, 2017)
In this paper, spectroscopic and quantum mechanical investigation of nine 4-aryl-5-arylazo-3-cyano-6-hydroxy-2-pyridone dyes was performed, and obtained density functional theory (DFT) results were compared with experimental ...
Volumetric and viscometric study and modelling of binary systems of diethyl tartrate and alcohols
(Elsevier Science Bv, Amsterdam, 2017)
Density, viscosity, refractive index and speed of sound have been measured for the pure ester diethyl tartrate at atmospheric pressure and over the temperature range from 288.15 K to 323.15 K. Detailed investigation regarding ...
Dextran coated silver nanoparticles Chemical sensor for selective cysteine detection
(Elsevier Science Bv, Amsterdam, 2017)
A simple, fast and non-costly method for selective cysteine (Cys) detection, based on optical changes of silver colloids, is developed. For that purpose, stable colloids consisting of silver nanoparticles (Ag NPs) coated ...
Recent developments in microfiltration and ultrafiltration of fruit juices
(Elsevier, Amsterdam, 2017)
This article provides an overview of recent developments and the published literature in microfiltration (MF) and ultrafiltration (UF) of fruit juices. In this review, we summarize studies by relating basic concepts 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 ...
Natural sorbents modified by divalent Cu2+- and Zn2+- ions and their corresponding antimicrobial activity
(Elsevier Science Bv, Amsterdam, 2017)
The objective of this study was to investigate the modification of materials used in wastewater treatment for possible antimicrobial application(s). Granulated activated carbon (GAC) and natural clinoptilolite (CLI) were ...
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 ...
Isopiestic determination of the osmotic and activity coefficients of the {yMg(NO3)(2) + (1-y)MgSO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2017)
Isopiestic (vapor pressure) measurements were made for aqueous mixtures of Mg(NO3)(2) and MgSO4 at T = (298.15 +/- 0.01) K with Mg(NO3)(2) ionic strength fractions y = (0.19691, 0.42542, 0.60113, 0.79583, and 1), along ...
