Surface Characterization of Iron-Modified Sepiolite by Inverse Gas Chromatography
(Amer Chemical Soc, Washington, 2011)
Inverse gas chromatography at infinite and finite surface coverages was applied to evaluate the surface properties of an iron-modified sepiolite sorbent, Fe-sepiolite. The adsorptions of different nonpolar and polar probes ...
Toward Optimum Working Fluid Mixtures for Organic Rankine Cycles using Molecular Design and Sensitivity Analysis
(Amer Chemical Soc, Washington, 2013)
This work presents a Computer-Aided Molecular Design (CAMD) method for the synthesis and selection of binary working fluid mixtures used in Organic Rankine Cycles (ORC). The method consists of two stages, initially seeking ...
A Study of Applicability of Nonlinear Frequency Response Method for Investigation of Gas Adsorption Based on Numerical Experiments
(Amer Chemical Soc, Washington, 2013)
A study of the applicability of the Nonlinear Frequency Response (NFR) approach for investigation of equilibrium and kinetics of gas adsorption, based on numerical simulations, is presented. Pressure responses of a batch ...
Removal of Sulfur Compounds from Mineral Insulating Oils by Extractive Refining with N-Methyl-2-pyrrolidone
(Amer Chemical Soc, Washington, 2012)
Copper sulfide deposits in the insulation systems of power transformers decrease the dielectric properties of the insulation and therefore constitute a significant risk for the operation of power transformers. Disulfides, ...
Degradation of the Insulating System of Power Transformers by Copper Sulfide Deposition: Influence of Oil Oxidation and Presence of Metal Passivator
(Amer Chemical Soc, Washington, 2010)
Deposition of conductive copper sulfide on paper insulation of power transformers was recognized as a serious risk that can result in equipment failure. The aim of this study was to investigate the influence of mineral ...
Lipase-Catalyzed Esterification of Phloridzin: Acyl Donor Effect on Enzymatic Affinity and Antioxidant Properties of Esters
(Amer Chemical Soc, Washington, 2014)
Lipase-catalyzed acylation of phloridzin with a wide range of fatty acids and antioxidant activities of synthesized esters were investigated in this study. Polar solvents were suitable reaction media for esterification, ...
Influence of TEMPO-Mediated Oxidation on Properties of Hemp Fibers
(Amer Chemical Soc, Washington, 2012)
Hemp fibers are a very interesting natural material for textile and technical applications, but some of these applications require improved and/or specific fiber properties. In order to modify hemp fibers for obtaining ...
