1. For instance, grinding a sample to a higher specific surface area increases its reactivity. 2. Increasing the amount of TMCS concentration reduces the specific surface area of the silica nanostructured particles. 3. The specific surface area of silica fume can be measured with the BET method or nitrogen adsorption method. 4. Based on the very high specific surface area of aluminium those platelets instantaneously oxidize upon contact with air. 5. They exhibit permanent porosity with specific surface areas surpassing those of well-known zeolites and porous silicates. 6. Silt is mineralogically like sand but with its higher specific surface area it is more chemically active than sand. 7. The grinding process is controlled to obtain a powder with a broad directly proportional to the specific surface area . 8. Moreover, specific surface area is a scale dependent quantity and no single true value exists for this parameter. 9. The resulting material offers specific surface area of 1628 m2 g-1, electrical conductivity and mesoporous structure. 10. This arises from the large specific surface area and differences in surface atomic structure of nanoparticles at small particle sizes.
