Advantages

Concentration tunes stability

Slight differences in structure and particle size of ABCC prepared at different initial concentrations drastically influence their thermal stability under heating in air.

Crystallization pathway controllable

Transformation from ABCC to BCC in aqueous solution proceeds via attachment of nanoparticles, where interfacial structural rearrangement during aggregation dominated crystallization kinetics.
