Nonlinear frequency response analysis of nonisothermal adsorption controlled by macropore diffusion
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this work, a nonlinear frequency response (NFR) approach is used for a theoretical study of nonisothermal adsorption controlled by macropore diffusion (NMD). Based on the nonlinear mathematical model on the particle ...
Novel support for enzyme immobilization prepared by chemical activation with cysteine and glutaraldehyde
(Elsevier, Amsterdam, 2014)
Immobilization of enzymes on glutaraldehyde-activated supports has been largely used on supports previously activated with amine groups. Therefore, the supports are positively charged hence usually the immobilization is ...
Novel alginate based nanocomposite hydrogels with incorporated silver nanoparticles
(Springer, Dordrecht, 2012)
Alginate colloid solution containing electrochemically synthesized silver nanoparticles (AgNPs) was investigated regarding the nanoparticle stabilization and possibilities for production of alginate based nanocomposite ...
Oxidized and Ethylenediamine-Functionalized Multi-Walled Carbon Nanotubes for the Separation of Low Concentration Arsenate from Water
(Taylor & Francis Inc, Philadelphia, 2013)
In this work multiwalled carbon nanotubes (MWCNTs) modified by oxidation (o-MWCNTs) and by aminofunctionalization (e-MWCNTs) were examined as potential adsorbents for arsenate removal from water. Adsorption characteristics ...
Integrated production of lactic acid and biomass on distillery stillage
(Springer, New York, 2013)
The possibilities of parallel lactic acid and biomass production in batch and fed-batch fermentation on distillery stillage from bioethanol production were studied. The highest lactic acid yield and productivity of 92.3 % ...
Electrochemical instability of Pt nanoparticles probed by formic acid oxidation
(Elsevier Science Sa, Lausanne, 2012)
A detrimental effect of CO on the stability of Pt nanoparticles, which is important for fuel cells technology, is demonstrated by the change in HCOOH kinetics on Pt nanoparticles caused by the presence of CO in the ...
Spectroscopic characterization of YAG and Nd:YAG single crystals
(IOP Publishing Ltd, Bristol, 2014)
In this paper, we used the Czochralski method to obtain good quality yttrium aluminium garnet (YAG, Y3Al5O12) and yttrium aluminium garnet doped with neodymium (Nd: YAG) crystals. The investigations were based on the growth ...
Prediction of municipal solid waste generation using artificial neural network approach enhanced by structural break analysis
(Springer Heidelberg, Heidelberg, 2017)
This paper presents the development of a general regression neural network (GRNN) model for the prediction of annual municipal solid waste (MSW) generation at the national level for 44 countries of different size, population ...
Sugar Beet Pulp as Leuconostoc mesenteroides T3 Support for Enhanced Dextransucrase Production on Molasses
(Humana Press Inc, Totowa, 2016)
Sugar beet pulp (SBP) and molasses, as an agro industrial waste material, are produced in large amounts annually. Thus, a major challenge nowadays is to develop procedures that could increase the value of the generated ...
Removal of Anthraquinone Dye by Cross-Linked Enzyme Aggregates From Fresh Horseradish Extract
(Wiley, Hoboken, 2016)
Horseradish roots (Armoracia rusticana) fresh extract was the source of unpurified horseradish peroxidase (HRP) which was used for the immobilization in a form of cross-linked enzyme aggregates (CLEAs). Among three ...
