Modelling and optimization of supercritical CO2 extraction of St. John's Wort (Hypericum perforatum L.) using genetic algorithm
(Elsevier Science Bv, Amsterdam, 2012)
Modelling and optimization of the extraction of St. John's Wort using supercritical fluid is the subject of this study. Applying conservation of mass, two partial differential equations were written for solute concentration ...
Investigation of copper-alginate microbeads as antimicrobial materials for potential biomedical applications
(Wiley-Blackwell, Hoboken, 2012)
Properties and drug release profile of poly(N-isopropylacrylamide) microgels functionalized with maleic anhydride and alginate
(Springer, New York, 2013)
This study highlights the advantages of functionalized poly(N-isopropylacrylamide) (PNIPAAm) microgels over pure PNIPAAm microgels in terms of polymer network properties and drug release profiles. PNIPAAm network was ...
Influence of surface modified TiO2 nanoparticles by gallates on the properties of PMMA/TiO2 nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Nanocomposites based on poly(methyl methacrylate) (PMMA) and TiO2 nanoparticles were synthesized by in situ radical polymerization of MMA in solution. The surface of TiO2 nanoparticles was modified with four gallic acid ...
Evaluation of periodic processes with two modulated inputs based on nonlinear frequency response analysis. Case study: CSTR with modulation of the inlet concentration and flow-rate
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In our previous work, a new, fast and easy, nonlinear frequency response method for analysing potential improvements of reactor performance by forced periodic operation was presented. This method, which is based on Volterra ...
Mechanical and thermal properties of UV cured mixtures of linear and hyperbranched urethane acrylates
(Elsevier Science Sa, Lausanne, 2012)
The properties of urethane acrylate resin mixtures based on the linear and hyperbranched aliphatic polyesters were examined. Linear polyester was synthesized from neopentil glycol and adipic acid. Hyperbranched polyester ...
Synthesis of fluorine substituted hydroxyapatite nanopowders and application of the central composite design for determination of its antimicrobial effects
(Elsevier Science Bv, Amsterdam, 2014)
Synthetic biomaterials based on fluorine substituted hydroxyapatite are potentially attractive for orthopedic and dental implant applications. The new synthesis of fluorine substituted hydroxyapatite samples were done by ...
The microbial eukaryote Blastocystis is a prevalent and diverse member of the healthy human gut microbiota
(Oxford Univ Press, Oxford, 2014)
To date, the majority of research into the human gut microbiota has focused on the bacterial fraction of the community. Inevitably, this has resulted in a poor understanding of the diversity and functionality of other ...
Synergistic Effect of Enzyme Hydrolysis and Microwave Reactor Pretreatment as an Efficient Procedure for Gluten Content Reduction
(Foods, 2021)
In this study, we assessed the effects of microwave irradiation of wheat gluten proteins as a pretreatment performed in a microwave reactor that could accurately control process parameters as a function of power and ...
Dispersion efficiency of montmorillonites in epoxy nanocomposites using solution intercalation and direct mixing methods
(Elsevier Science Bv, Amsterdam, 2018)
The major aims of this paper are the investigation of the effects of the mixing procedure and the montmorillonite (Mt) surface modification on the structure (optical microscopy, XRD, TEM, SEM), rheological, mechanical ...
