Pore size distribution of unsupported SnO2 membranes prepared by sol-gel process - Code: EP21
Unsupported SnO2 membranes were prepared by sol-gel process and characterized by N2 adsorption-desorption isotherms and X-ray diffraction. Results show that the texture of dried samples does not change appreciably with the ...
Effect of the pore geometry in the characterization of the pore size distribution of activated carbons
in this work, the characterization of Activated Carbons (AC) by using the independent pore models is discussed, with special emphasis on the issue of how the assumed pore geometry can affect the resulting Pore Size ...
On the influence of heterogeneity of graphene sheets in the determination of the pore size distribution of activated carbons
We model carbon-based microporous materials,such as activated carbons, taking into account surface defects in the form of geometrical rugosity in the inner surface of each graphitic slit pore. The used model is a simplified ...
Anisotropy of pore size classes’ connectivity related to soil structure under no tillage
(Lippincott Williams, 2013-11)
No-tillage (NT) systems have been increasing during the last several decades. Development of a near-surface layer of laminar structure under NT has also been reported. The objectives of this work were to determine whether ...
New insights on estimating pore size distribution of latex particles: Statistical mechanics approach and modeling
(Elsevier Science, 2016-04)
New statistical mechanics approach for pore size distribution applied in wide the relative pressure range is proposed. The new proposed model was applied to nitrogen adsorption-desorption isotherms at 77 K onto five ...
Formation of SnO2 supported porous membranes
(Kluwer Academic Publ, 1997-01-01)
In this work, the effect of the substrate microstructure on the formation of SnO2 membranes and of the sintering conditions on their porosity have been analysed. Samples have been prepared by colloidal suspensions cast on ...
Pore size evolution during sintering of ceramic oxides
This paper reviews the influence of particle size distribution, agglomerates, rearrangement, sintering atmospheres and impurities on the pore evolution of some commonly studied oxides. These factors largely affect sintering ...
Pore Size Distribution of Ordered Nanostructured Carbon CMK-3 by means of Experimental Techniques and Monte Carlo Simulations
The design and study of new materials with specific properties is interesting in several scientific and technological fields. In the last years, nanostructured carbons (NC) have rapidly attracted the attention of some ...
Mass transfer and transport during purification of fructooligosaccharides by nanofiltration
