Pore size distribution and accessible pore size distribution in bituminous coals
International Journal of Coal Geology, 2012The porosity and pore size distribution of coals determine many of their properties, from gas release to their behavior on carbonization, and yet most methods of determining pore size distribution can only examine a restricted size range. Even then, only accessible pores can be investigated with these methods.

Crystalline bicyclic diol 1 forms H-bonded hexamers of 1, whereas the molecules of diol 2 are packed in a crystal because of CH···O contacts without the formation of cavities.

Pore Size Distribution Studies
Journal of the Soil Mechanics and Foundations Division, 1971Pore-size distribution data for pores of diameters down to 0.016 μm were obtained by mercury porosimetry for a number of laboratory-prepared specimens. Statically-compacted specimens of a kaolinite, an illite, and Boston Blue Clay were evaluated, and changes in the pore-size distribution of the kaolinite were followed as a function of increasing amount

Two techniques, liquid extrusion with water and optical microscopy on embedded carpet samples, are used to assess pore size distribution and location within the pile of a cut pile carpet manufactured from a polypropylene backing, crosslinked styrene butadiene rubber adhesive, and nylon pile.

AbstractA new, fast, and simple method based on size exclusion chromatography permits determination of the volumes of open and closed pores of rigid solids such as silica or porous glasses, together with the specific surface and the pore‐size distribution for pore diameters ranging from 10 to 4000Å. The results are in good agreement with those obtained

From pore size distribution to an equivalent pore size of cement mortar
Materials and Structures, 1990An experimental and theoretical study has been performed with the aim of quantifying pore size distribution curves and correlating them with water and oxygen permeability. Twenty mortars have been investigated which contained Portland cement, blast-furnace slag cement and silica fume as a binder. Admixtures have been used as well.

Mean pore sizes from flow measurements
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1973A method is described in this note for determining the mean pore size of a porous plug from direct current measurements and hydraulic flows. This study deals with fitted glass disks having properties similar to a spectrum of soils ranging from a fine sand to a silty clay whose mean pore size can be determined by combining current characteristics with ...

Journal of Catalysis, 1984
Abstract The problem of catalyst deactivation by active site poisoning and pore blockage is analyzed. The effect of catalyst size, average pore size, and pore size distribution on the phenomenon of deactivation is investigated for two simple pore structure models, i.e., the “single pore” and “parallel bundle of pores” models.

Pore Size, Particle Size, Aggregate Size, and Water Retention
Soil Science Society of America Journal, 1990Abstract Measurements of water retention and pore‐size distribution for a soil are time consuming and affected by changes in aggregate‐size distribution. A method of compared distribution curves was used to relate distributions of pore size (PO), particle size (PA), aggregate size (AG), and pore size from water ...
