Aggregates breaking

Thus, analyses of how aggregates break have resorted to idealizations inspired by traditional fluid mechanical analysis, two limit cases being per-... 

The presence of organics appears to facilitate aggregate break-up. Flux decline is independent of transmembrane pressure and it is therefore assumed that the cake is not compacted. The aggregate... 

The size of the aggregates is of less critical importance when the aggregate strucmre is soft and weak due to the ultimate particles having a low coalescence factor. Particularly in the case of ultimate silica particles larger than about 50 nm, when the coalescence factor is less than 10%, the powder is so soft that it is difficult to determine the aggregate size, since the aggregates break apart when subjected even to mild mechanical forces. As stated above such a soft powder is useful when a 100% dense, transparent, pore-free silica body is to be prepared. 

Additions of (3-cyclodextrin increased the CMC of bisquaternary ammonium surfactants [95]. Addition of (3-cyclodextrin to nonionic gemini surfactant [Q] where X = OH causes a gradual change in the size and form of the aggregates. Rod-shaped aggregates form upon increasing cyclodextrin content. More and more rods form whereas the micellar aggregates break up [96,97]. 

In the solid state, PhaSbOAc has a distorted trigonal bipyramidal structure phenyl groups and lone-pair equatorial with bonded oxygen (Sb-O 213.7) and bridging oxygen (Sb-O 259.2, 251.3) axial. In solution the aggregation breaks down. ...
