Effect of microgravity on the crystallization of a self-assembling layered material

Article Abstract:

Researchers have investigated the impact of a microgravity environment on the crystallization of layered microporous tin(IV) sulphides, a class of materials with a crystal structure determined by weak interlayer interactions and by strong intralayer covalent bonds. These sulphides had already been found to be interesting for the sensitivity of their crystal growth to the uniformity of the solution environment. It was established that microgravity effect is probably responsible for the differences in interlayer registry and population of defects seen in space- and Earth-grown crystals.

Synthesis of inorganic materials with complex form

Article Abstract:

Inorganic materials with complex form can be synthesized chemically by replicating the patterns of preorganized or self-organized organic assemblies such as micelles, vesicles, and foams. Biomineralization related synthetic approaches provide an effective way to accomplish this goal. Transcriptive and synergistic synthesis, metamorphic reconstruction, and microphase separation aid the development of inorganic morphosynthesis.

Coupled synthesis and self-assembly of nanoparticles to give structures with controlled organization

Article Abstract:

The interfacial activity of reverse micelles and microemulsions can be used to couple nanoparticle synthesis and self-assembly over a range of length scales, producing materials with complex organization. Three different barium chromate nanostructures were produced, linear chains, rectangular superlattices and long filaments.
