The mechanical properties of compacts of unlubricated microcrystalline cellulose and silicified microcrystalline cellulose were evaluated using the diametric tensile test. The results suggested that, under comparable testing conditions, compacts of silicified microcrystalline cellulose exhibited greater strength than those of microcrystalline cellulose.

The Young's modulus of a microcrystalline cellulose [PDF]
Cellulose, 2001 This research is concerned with an investigation into the determination of the micromechanical properties of a particulate form of cellulose, namely microcrystalline cellulose. Using the technique of Raman spectroscopy the shift in the 1095 cm-1 Raman band, characteristic of cellulose, with strain is monitored and compared to the deformation of natural

Abstract Silicified microcrystalline cellulose (SMCC) has been compared with a standard grade of microcrystalline cellulose (MCC) using several physicochemical techniques in order to elucidate any chemical or polymorphic changes in the material that could be attributed to the silicification process.

During the development of a tablet dosage form of an investigational compound, R411, several aspects were identified as critical quality attributes that required optimization. The use of nonsolvent processing prevented the moisture-induced physical changes in the drug product but presented manufacturing challenges related to sticking during compression

The adsorption of a model amine drug (tacrine hydrochloride) from aqueous solution onto 21 microcrystalline cellulose (MCC) based samples has been investigated. The MCC source (manufacturer) affected adsorption. The adsorption appeared to be fully reversible.

Fourier transform infrared spectroscopy analysis for hydrothermal transformation of microcrystalline cellulose on montmorillonite [PDF]
Applied Clay Science, 2014 Specifying the interactions between montmorillonite and cellulose is helpful for understanding the evolution of biomass in soil and the geological formation of fossil fuels in nature.

Microcrystalline cellulose in tableting
Journal of Pharmaceutical Sciences, 1966The development of microcrystalline cellulose has made available to the pharmaceutical industry an extremely valuable tableting agent. It was found that tablets of plain microcrystalline cellulose will tend to soften and swell when exposed to humid conditions, but the effect is reversed upon the removal of increased humidities.

Coagulation of microcrystalline cellulose dispersions
Journal of Colloid and Interface Science, 1969Abstract The coagulation effects on microcrystalline cellulose sols of simple ions, hydrolyzed metal ions, chelate complexes, and a series of alkylammonium chlorides differing in length of the hydrocarbon chain have been investigated. It was found that these sols are much more sensitive towards electrolytes than typical lyophilic colloids.

MICROCRYSTALLINE CELLULOSE STABILIZEDEMULSIONS
Journal of Dispersion Science and Technology, 1986ABSTRACT Miorocrystalline cellulose stabilized emulsions (o/w) were evaluated by means of brightfield and polarized light microscopy, freeze-etch electron microscopy, droplet size analyses and rheologic measurements. These studies indicated that miorocrystalline cellulose (Avicel RC591 ) forms a network around emulsified oil droplets.

True Density of Microcrystalline Cellulose
Journal of Pharmaceutical Sciences, 2005Microcrystalline cellulose (MCC) exhibits unusual tableting properties, sometimes, inconsistent with its high plasticity. It is found that some of the unusual tableting properties of MCC can be explained in part by the use of inaccurate true density during tableting data analysis.
