Structural characterization of electrospun micro/nanofibrous scaffolds by liquid extrusion porosimetry: a comparison with other techniques
(Elsevier Science, 2014-05-05)
Poly(e-caprolactone) micro/nanofibrous scaffolds obtained by electrospinning technique from polymer solutions were characterized in terms of fiber diameter (as measured by scanning electron microscopy - SEM), pore size and ...
Pore structure characterization of kaolin, metakaolin, and their acid-treated products using small-angle X-ray scattering
Pore structure of dealuminated kaolin and metakaolin was studied by small-angle X-ray scattering (SAXS). Both parent kaolin and metakaolin have about 10% of the total pore volume provided by globular pores with 105 Å mean ...
About the thermal stability and pore elimination in the ordered hexagonal mesoporous silica SBA-15
(Elsevier B.V., 2014-05-15)
Ordered hexagonal mesoporous silica was prepared using Pluronic P123 template and removal of the polymer by washing in ethanol. The thermal stability and the pore elimination was studied under heat treatment by a fixed ...
Pore structure description of mortars containing ground granulated blast-furnace slag by mercury intrusion porosimetry and dynamic vapour sorption
The description of the pore structure is a key aspect when studying the durability of cement-based materials. Many techniques have been developed over the years in order to describe the actual complex microstructure of ...
Why the pore geometry model could affect the uniqueness of the PSD in AC characterization
In this paper we discuss why the pore geometry can affect the unicity of the pore size distribution (PSD) of a given activated carbon (AC) sample, when different probe gases are used in adsorption measures. In order to ...
Formation of SnO2 supported porous membranes

Evaluation of Effective Saturation of Air-NLAPL on the Basis of Air-Water Tests in Soils with Multimodal Pore-Size Distribution
This paper was designed to verify if effective saturation distribution for air-LNAPL systems obtained indirectly as suggested by the American Petroleum Institute (2007) are adequate for soils of lateritic nature found in ...
