TEMPO-oxidized cotton as a substrate for trypsin immobilization: impact of functional groups on proteolytic activity and stability
(Springer, Dordrecht, 2017)
Cotton fibers containing different amounts of aldehyde and carboxyl groups were prepared by varying TEMPO oxidation conditions and then employed as carriers for trypsin immobilization. Depending on the functional group ...
Enzymatic conversion of sunflower oil to biodiesel in a solvent-free system: Process optimization and the immobilized system stability
(Elsevier Sci Ltd, Oxford, 2009)
The feasibility of using the commercial immobilized lipase from Candida antarctica (Novozyme 435) to synthesize biodiesel from sunflower oil in a solvent-free system has been proved. Using methanol as an acyl acceptor and ...
A novel method of preparing the silver chloride cathode for the magnesium seawater activated primary cell
(Journal of Power Sources, 2021)
The novel method based on the inexpensive and fast modified successive ion layer adsorption and reaction (SILAR) method of preparing silver chloride cathode on the carbon felt is developed. The electrochemical behavior of ...
The diffusion of water in poly(ditetrahydrofurfuryl itaconate)
(Elsevier Sci Ltd, Oxford, 2005)
The diffusion of water into solid poly(ditetrahydrofurfuryl itaconate) (PDTFI) films and in analogous polymer solutions was measured. Diffusion into solid PDTFI films on a glass support was measured in three solutions of ...
Electrochemical testing of noble metal dental alloys: The influence of their chemical composition on the corrosion resistance
(Corrosion Science, 2021)
Platinum and nine commercial dental alloys with the contents of noble metals ranging from 27 wt.% to 97.6 wt. % were investigated by the procedure described in the Standard ISO 10271:2009, Electrochemical testing was ...
Biodegradation of cotton and cotton/polyester with Ag/TiO2 nanoparticles in soil
(Elsevier Sci Ltd, Oxford, 2017)
This study discusses the biodegradation behavior of cotton and cotton/PET fabrics impregnated with Ag/TiO2 nanoparticles in soil. Biodegradation behavior was evaluated by standard test method ASTM 5988-03 based on determination ...
Influence of microenvironmental conditions on hybridoma cell growth inside the alginate-poly-L-lysine microcapsule
(Elsevier Sci Ltd, Oxford, 2007)
A mathematical model was formulated to describe hybridoma cell growth within the alginate-poly-L-lysine (alginate-PLL) microcapsules during air-lift bioreactor cultivation. Model development was based on experimentally ...
Battery type hybrid supercapacitor based on polypyrrole and lead-lead sulfate
(Elsevier Science Bv, Amsterdam, 2016)
The electrochemically synthesized polypyrrole and lead-lead sulfate is examined as a potential electrodes for battery-type hybrid supercapacitors in acidic solution. The device exhibits battery-type behavior at low discharge ...
Biosorption of heavy metal ions from aqueous solutions by short hemp fibers: Effect of chemical composition
(Elsevier Science Bv, Amsterdam, 2009)
Sorption potential of waste short hemp fibers for Pb2+, Cd2+ and Zn2+ ions from aqueous media was explored. In order to assess the influence of hemp fiber chemical composition on their heavy metals sorption potential, ...
Nonlinear Frequency Response of Electrochemical Methanol Oxidation Kinetics: A Theoretical Analysis
(Electrochemical Soc Inc, Pennington, 2010)
In this theoretical contribution, nonlinear frequency response analysis was applied for the investigation of electrochemical methanol oxidation. This technique expresses the input-output behavior of any weakly nonlinear ...
