Phase aggregate

These experiments have recently been extended to the case of iron. The synthesis of small Fe particles has long been difficult due to the lack of suitable precursor. However, using the complex Fe[N(SiMe3)2]2 as precursor, we have obtained nanoparticles of low size dispersity and displaying a magnetization 5 T higher than in bulk iron and comparable to that of gas phase aggregates [57].

In this case, the polymers containing less amounts of sulfonate groups showed a cholesteric mesophase, while if the content of ionic groups was increased, also a smectic phase appeared besides the cholesteric one [103]. This is because at higher ionic component, the ionic hard phases aggregate in domains due to their electrostatic... 

It is postulated that this process is consistent with the dilute phase aggregate model (1) forming Type A/Type B aggregates initially when mixed at 40°C, which rearrange to form a coacervate phase when the temperature is reduced below 35°C. 

The gelatin/gelatin coacervate systems studied appear to fit the Veis-Aranyi dilute phase aggregate model (1), forming aggregates by electrostatic interaction which may then associate to form a separate coacervate phase by the aid of gelation forces on temperature reduction.
