Porosity and Pore Size Distribution
نویسنده
چکیده
A soil’s porosity and pore size distribution characterize its pore space, that portion of the soil’s volume that is not occupied by or isolated by solid material. The basic character of the pore space affects and is affected by critical aspects of almost everything that occurs in the soil: the movement of water, air, and other fluids; the transport and the reaction of chemicals; and the residence of roots and other biota. By convention the definition of pore space excludes fluid pockets that are totally enclosed within solid material—vesicles or vugs, for example, that have no exchange with the pore space that has continuity to the boundaries of

The Preparation of Bamboo-Structured Carbon Nanotubes with the Controlled Porosity by CVD of Acetylene on Co-Mo/MCM-41
Bamboo-structured carbon nanotubes are grown on Co-Mo/MCM-41 catalyst in the temperature range of 873-973 K by thermal chemical vapor deposition of acetylene. This study shows that the purified carbon nanotubes have open tips and the metals of the catalyst are not encapsulated. Thus, the bamboo-structure seems to grow from the base. Pore size distribution of the product is quite narrow and ...
متن کاملPore size distribution in tablets measured with a morphological sieve.
Porosity and pore structure are important characteristics of tablets, since they influence mechanical strength and many other properties. This paper proposes an alternative method for the characterization of pore structure based on image analysis of SEM micrographs. SEM images were made of sodium chloride tablets made with three different particle sizes. The pore size distribution in these imag...
متن کاملThe effect of sulfuric acid on pore initiation in anodic alumina formed in oxalic acid
In this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. Effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. Electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (SEM) techniques, respectively. Effe...
متن کاملPorosity, pore size distribution and in situ strength of concrete
In this study, in situ strength of concrete was determined through compression test of cores drilled out from laboratory cast beams. The apparent porosity and pore size distribution of the same concrete were determined through mercury intrusion porosimetry, performed on small-drilled cores. The normal-strength concrete mixes used in the experimental investigation were designed to exhibit a wide...
متن کاملModelling mass transport through a porous partition: Effect of pore size distribution
Direct contact membrane distillation process has been studied using microporous polytetrafluoroethylene and polyvinylidene fluoride membranes. The membranes were characterized in terms of their non-wettability, pore size distribution and porosity. The mean pore sizes and pore size distributions were obtained by means of wet/ dry flow method. The mean pore size and the e¤ective porosity of the m...
