Mesocrystals: Inorganic Superstructures Made by Highly Parallel Crystallization and Controlled Alignment

Mesocrystals: inorganic superstructures made by highly parallel crystallization and controlled alignment.

Controlled self-organization of nanoparticles can lead to new materials. The colloidal crystallization of non-spherical nanocrystals is a reaction channel in many crystallization reactions. With additives, self-organization can be stopped at an intermediary step-a mesocrystal-in which the primary units can still be identified. Mesocrystals were observed for various systems as kinetically metast...

Mesocrystals--ordered nanoparticle superstructures.

Mesocrystals are 3D ordered nanoparticle superstructures, often with internal porosity, which receive much recent research interest. While more and more mesocrystal systems are found in biomineralization or synthesized, their potential as material still needs to be explored. It needs to be revealed, which new chemical and physical properties arise from the mesocrystal structure, or how they cha...

Mesocrystals and Nonclassical Crystallization

Mesocrystals and Nonclassical Crystallization

This chapter presents a history of observations that crystallization can go well beyond the simple ‘expected’ behaviour found in the salt cellar or when you buy a chemical. Biomorphs, crystal gardens, ‘crystal souls’, but also the remarkable pattern and structures of biominerals made researchers think that there is something beyond the concept of the bare three-dimensional regularity of molecul...

Tubular MFI Zeolite Membranes Made by In-Situ Crystallization

Polycrystalline MFI zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared by four subsequent hydrothermal ...
