Pore Structure and Fractal Characteristics of Activated Carbon Fibers Characterized by Using HRTEM

Texture analysis of TEM micrographs of alginate gels for cell microencapsulation

“…As an example, cytoplasmic texture was analyzed using Fourier and autocorrelation image processing techniques within the study of a valuable model for human lens aging (Freel et al, 2002). Fast Fourier transform has also been used for characterizing the pore microstructure of activated carbon fibers (Huang et al, 2002). An interesting approach is based on fractal theory that has been applied in various works from material science to bioengineering.…”

“…TEM images has been quantitatively analyzed in several ways and in different contexts (Freel et al, 2002;Huang et al, 2002). As an example, cytoplasmic texture was analyzed using Fourier and autocorrelation image processing techniques within the study of a valuable model for human lens aging (Freel et al, 2002).…”

Physicochemical Properties of Carbon Materials: A Brief Overview

“…As a final comment, it should be mentioned that the fractal approach [211,212] to the elucidation of carbon surface physics (including pore size distribution, surface roughness, and transport characteristics), although initially very promising [213][214][215][216][217][218][219][220][221][222][223][224][225][226][227], does not yet seem to have fulfilled the optimistic expectations. For example, Huang et al [224] combined TEM with image processing to investigate the micropore structure of two rayon-derived ACFs and concluded, rather prosaically, that the "fractal dimensions obtained were consistent with those obtained by nitrogen adsorption." More recent studies along the same lines seem to be devoted to the characterization of carbon nanotubes [228,229].…”

A high CO2 permselective mesoporous silica/carbon composite membrane for CO2 separation

“…The pore structure of carbon membrane is mainly composed of the disordered inter-connective nano-channels formed by the intergranular holes (supermicropores) packed by the turbostratic carbon microcrystals and the space (ultramicropores) existed between the carbon sheets [3,4].…”
