Mesopore structure of microcrystalline cellulose tablets characterized by nitrogen adsorption and SEM: The influence on water-induced ionic conduction

Article Abstract:

Nitrogen adsorption isotherms and SEM micrographs of microcrystalline grades of cellulose (MCC) tablets formed at different compaction pressures are analyzed to obtain information about tablet pore structure, surface area and fractal dimension of internal pore surfaces. The results are compared to the ionic charge transport properties of the cellulose tablets and the fractal analysis of nitrogen isotherms have showed that the dominant interface forces during adsorption is attributed to the surface tension between the gas and the adsorbed liquid phase.

Conductivity percolation in loosely compacted microcrystalline cellulose: An in situ study by dielectric spectroscopy during densification

Article Abstract:

A study of the water-induced ionic charge transport in cellulose is presented. The behavior of this transport in loosely compacted microcrystalline cellulose (MCC) powder is investigated as a function of density utilizing a new type of measurement setup, allowing for dielectric spectroscopy measurement in situ during compaction.
