Behavior of LNAPL in soils with multimodal pore-size distribution
(Ios Press, 2015-01-01)
New models are presented to characterize the behavior of light nonaqueous phase liquids (LNAPL) and determine their specific volume in soils with a multimodal distribution of pores making an adaptation of the information ...
Pore size distribution of unsupported SnO2 membranes prepared by sol-gel process - Code: EP21
(1994-01-01)
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
(Springer, 2013-04)
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 ...
Vapor intrusion in soils with multimodal pore-size distribution
(2016-09-12)
The Johnson and Ettinger [1] model and its extensions are at this time the most widely used algorithms for estimating subsurface vapor intrusion into buildings (API [2]). The functions which describe capillary pressure ...
Modelo Estocástico para bloqueio de poros e redução de permeabilidade
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2014-01-29)
Modeling transport of particulate suspensions in porous media is essential for understanding
various processes of industrial and scientific interest. During these processes, particles are
retained due to mechanisms like ...
On the influence of heterogeneity of graphene sheets in the determination of the pore size distribution of activated carbons
(Springer, 2011-02)
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 ...
