Magnetite from magnetotactic bacteria: Size distributions and twinning
Magnetite magnetotactic bacteria Size distributions twinning
2012/4/1
We studied intracellular magnetite particles produced by several morphological types of magnetotactic bacteria including the spirillar (helical) freshwater species,Magnetospirillum magnetotacticum,and...
Oriented attachment and growth, twinning, polytypism, and formation of metastable phases: Insights from nanocrystalline TiO2
Oriented attachment growth twinning polytypism formation of metastable phases Insights nanocrystalline TiO2
2012/4/1
Atomic-resolution transmission electron micrographs show that nanocrystalline TiO2 coarsens by oriented attachment and growth under hydrothermal conditions. In addition to forming homogeneous single c...

Twinning in synthetic anorthite: A transmission electron microscopy investigation
Twinning synthetic anorthite transmission electron microscopy investigation
2012/4/1
Transmission electron microscopy (TEM) has revealed dense, complex twins in synthetic
anorthite crystals formed by annealing CaAl2Si20g glass. The crystals are dominated by
Carlsbad and Carlsbad-alb...
Bottinoite, Ni(H2O)6[Sb(OH)6]2: Crystal structure, twinning, and hydrogen-bond model
Bottinoite Ni(H2O)6[Sb(OH)6]2 Crystal structure twinning hydrogen-bond model
2012/4/9
The crystal structure ofbottinoite, Ni(H20MSb(OH)6L, wasdetermined from a twinned crystal. This study revealed that the strong 31m pseudosymmetry shown by allthe natural and synthetic crystals examine...
