Grain Size Control Of Mesoporous Silica And Formation Of

Nov 03, 2004 The architecture of mesoporous silica was successfully controlled by adjusting the concentrations of a cationic surfactant and ammonia. An excess amount of the surfactant suppressed the grain growth and then induced the formation of small grains with a diameter below 20 nm. Consequently, assembly of the small-sized grains produced a bimodal pore structure consisting of framework

Compaction Creep Of Sands Due To Timedependent Grain

Sep 24, 2014 However, a clear effect of grain size on the number of AE events n AE counted per unit e v can be seen Figure 9. This behavior may be explained with a simple model in which failure of a sand grain is considered to contribute to an incremental volume change equal to d 3, where is a dimensionless constant 0 6.
