Electrical and morphological characterization of multiwalled carbon nanotubes functionalized via the Bingel reaction
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
Covalent sidewall functionalization of multiwalled carbon nanotubes (MWCNTs) has been performed using two approaches, direct and indirect cycloaddition through diethyl malonate, based on the Bingel reaction. The results ...
Periodic Operation with Modulation of Inlet Concentration and Flow Rate Part II: Adiabatic Continuous Stirred-Tank Reactor
(Wiley-VCH Verlag Gmbh, Weinheim, 2016)
The nonlinear frequency response (NFR) method, which is an analytical, fast, and easy method for evaluating the performance of forced periodically operated chemical reactors, was used to investigate possible improvements ...
Synthesis, structural and biological characterization of 5-phenylhydantoin derivatives as potential anticonvulsant agents
(Springer Wien, Wien, 2012)
Considering the importance of hydantoin derivatives in treatment of status epilepticus, four 5-phenylhydantoins, whose lipophilicities were estimated to be similar to that of phenytoin, were synthesized. Evaluation of their ...
Experimental measurements and modelling of volumetric properties, refractive index and viscosity of selected binary systems with butyl lactate at 288.15-323.15 K and atmospheric pressure. New UNIFAC-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2013)
Densities, refractive indices and dynamic viscosities of three binary systems: butyl lactate + 1-propanol, butyl lactate + 1,2-propanediol and butyl lactate + 1,3-propanediol, have been measured in temperature range ...
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 ...
