Isolation of ribosome microcrystals
Journal of Molecular Biology, 1970Abstract A method of isolating large quantities of crystallized ribosomes from hypothermic chick embryos is described. The isolated ribosome crystals maintain the same average dimensions and the same type of aggregations as those prepared in vivo .

Magnetically Responsive Calcium Carbonate Microcrystals
ACS Applied Materials & Interfaces, 2009Here we report the fabrication of magnetically responsive calcium carbonate microcrystals produced by coprecipitation of calcium carbonate in the presence of citrate-stabilized iron oxide nanoparticles. We demonstrate that the calcite microcrystals obtained possess superparamagnetic properties due to incorporated magnetite nanoparticles and can be ...

Framboids are constituted by microcrystals with approximately log-normal size-frequency distributions, and 95% of framboidal microcrystals are between 0.1 and 3.1 μm. Nanocrystals are not generally observed in framboids. Packing efficiencies vary between close-packings in which the microcrystals occupy up to 74% of the framboid volume and random ...

Framboid microcrystals grow through surface reaction of S2(-II) or H2S with =FeS moieties at defect sites on the pyrite crystal surface. The surface energies of pyrite vary from the most stable cubic through octahedral to pyritohedral and dodecahedral surfaces.

Supramolecular chirality in peptide microcrystals
Chemical Communications, 2015VCD reveals supramolecular chirality in microcrystals of two peptide segments from human islet amyloid (IAPP, amylin). Previously such supramolecular chirality has been observed by VCD only for amyloid fibrils.

Rare forms of diamond growth and dissolution are described using the example of diamond microcrystals from the Samotkan’ Neogene titanium–zirconium placer on the Ukrainian Shield. These include diamond crystals with complex faceting, microblock crystals, skeletal crystals, vertex-shaped crystals, crystals with natural dissolution, and ideal twins.

Microcrystals of a Modified Fibrinogen
Nature, 1972Fibrinogen forms microcrystals after cleavage with an enzyme from Pseudomonas. Electron microscope images reveal a close relation between these structures and fibrin. The results support the view that no major intramolecular rearrangement occurs in the fibrinogen-fibrin conversion.
