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 ...
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, ...
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 ...
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 ...
Bactericidal Efficiency of Silver Nanoparticles Deposited onto Radio Frequency Plasma Pretreated Polyester Fabrics
(Amer Chemical Soc, Washington, 2010)
The potential application of low-temperature radio frequency (RF) plasma for fiber surface activation in order to enhance the binding efficiency of colloidal silver nanoparticles onto the polyester fabrics and improve the ...
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 ...
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 ...
Comparative Study of Batch and Fluidized Bed Bioreactors for Lipase-Catalyzed Ethyl Cinnamate Synthesis
(Amer Chemical Soc, Washington, 2013)
Ethyl cinnamate, an ester known as flavor and fragrance compound, has been synthesized using two immobilized bioreactor systems, batch and fluidized bed bioreactors. The enzyme used for this synthesis is a commercial lipase ...
Multiscale and Multiphase Model of Fixed Bed Reactors for Fischer-Tropsch Synthesis: Intensification Possibilities Study
(Amer Chemical Soc, Washington, 2017)
A multiphase fixed-bed reactor (FBR) model for Fischer Tropsch Synthesis has been developed. A high level of details is considered for description of the phenomena on the reactor and particle scale. Detailed kinetics is ...
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), ...
