Formation of single-domain magnetite by a thermophilic bacterium
Formation single-domain magnetite bacterium
2012/4/1
Magnetite is a common product of bacterial iron reduction and may serve as a potential physical indicator of biological activity in geological settings. Here we report the formation of single-domain m...
Memory effects of domain structures during displacive phase transitions: A high-temperature TEM study of quartz and anorthite
Memory effects domain structures displacive phase transitions high-temperature TEM study of quartz anorthite
2012/4/1
Memory effects ass~iated with the Dauphine twins in a quartz and the c-antiphase
domains (c-APDs) in PI anorthite have been investigated by in situ hot-stage transmission
electron microscopy (TEM). ...
TEM investigation of the domain structure and superstructure in hillebrandite, Ca2SiO3(OH)2
TEM investigation domain structure superstructure hillebrandite Ca2SiO3(OH)2
2012/4/9
Selected-area electron diffraction, dark-field images, and high-resolution transmission electron microscope images show that there are pervasive domains in hillebrandite from Mexico. The domains are i...

Particle Shape versus Coherent Scattering Domain of Illite/Smectite: Evidence from HRTEM of Dolna Ves Clays
Coherent scattering domain Fundamental particle HRTEM Illite/Smectite Mixed-layer crystal
2011/12/27
Fundamental particle thickness measurements of Dolná Ves hydrothermal illite/smectite (I/S) samples confirmed earlier findings regarding the content of fixed cations in illite interlayers (ca. 0.9/O10...
Domain Segregation in Ni-Fe-Mg-Smectites
Chemical composition Laterite Mossbauer spectroscopy Nickel Nontronite Pimelite Smectite Transmission electron microscopy
2011/11/25
Abstract: The first stage of lateritic weathering of pyroxenes in the Niquelandia area, Brazil, leads either to Fe-rich products or to a phyllosilicate clay. In relatively unfractured parent rock the ...
