Study of polypropylene surface modification by air dielectric barrier discharge operated at two different frequencies
(2012-10-18)
In this work, air dielectric barrier discharge (DBD) operating at the line frequency (60 Hz) or at frequency of 17 kHz was used to improve the wetting properties of polypropylene (PP). The changes in the surface hydrophilicity ...

Computational Design Solutions in architectural education: The use of script language to design complex surfaces
(Universidad La Salle, 2014-07-16)
In this paper, the author explains why architects who know how to use scripts have an advantage over the ones who just know how to manipulate a specific software. The reason behind this affirmation is that knowing how to ...
Biocatalysts based on nanozeolite-enzyme complexes: Effects of alkoxysilane surface functionalization and biofuel production using microalgae lipids feedstock
(2018-05-01)
Nanozeolites with different crystallographic structures (Nano/TS1, Nano/GIS, Nano/LTA, Nano/BEA, Nano/X, and Nano-X/Ni), functionalized with (3-aminopropyl)trimethoxysilane (APTMS) and crosslinked with glutaraldehyde (GA), ...
Electrochemical and Monte Carlo studies of self-assembled trans-[Fe(cyclam)(NCS)2]+ complex ion on gold surface as electrochemical sensor for nitric oxide
(ElsevierAmsterdam, 2013-02)
Modification of gold electrode by self-assembled trans-[Fe(cyclam)(NCS)2]+ complex ion to produce an electrochemical sensor for nitric oxide detection was investigated. Dopamine, serotonin and nitrite were examined as ...
Numerical study of the square-root conformation tensor formulation for confined and free-surface viscoelastic fluid flows
(2016-12-01)
We present a numerical study of a stabilization method for computing confined and free-surface flows of highly elastic viscoelastic fluids. In this approach, the constitutive equation based on the conformation tensor, which ...
Charge regulation in redox active monolayers embedded in proton exchanger surfaces
(Royal Society of Chemistry, 2012-07)
Experimental evidence of the variation in redox potential of osmium pyridine complexes tethered to a Au surface by thiol or diazonium chemistry at different ionic concentration and electrolyte pH is described. The interplay ...
Complexation at the edges of hydrotalcite: the cases of arsenate and chromate
(Elsevier Inc, 2012-11)
Sorption of CrO2 4 and HAsO2 4 by hydrotalcite, in its chloride form, was studied as a function of anion concentration. In both cases, the shape of the isotherms is langmuirian. The maximum uptake of CrO2 4 equals the ...
