High-resolution x-ray diffraction and scattering is a key tool for structure analysis not only in bulk materials but also at surfaces and buried interfaces from the sub-nanometer range to …
The existing macroscale models of the calcium (alumino) silicate hydrate (C-(A-) SH), the main binder of concrete, assume that the nanocrystallites maintain random orientation under …

High-pressure X-ray diffraction was carried out on a single crystal of gypsum compressed in a diamond anvil cell. The sample maintained its crystal structure up to 4.0±0.1 GPa. The fit of …
Abstract Seismic shear wave anisotropy,,,,, is observed in Earth's uppermost lower mantle around several subducted slabs. The anisotropy caused by the deformation-induced …
The anisotropy of physical properties is a well-known characteristic of many clay-bearing rocks. This anisotropy has important implications for elastic properties of rocks and must be …
Shales display significant seismic anisotropy that is attributed in part to preferred orientation of constituent minerals. This orientation pattern has been difficult to quantify because of the …
Dislocations in minerals have a long history: The first images of dislocations ever seen were obtained by Seidentopf in 1905 on rocksalt (halite) with an optical microscope. Since then …
We carried out sound velocity and density measurements on solid hcp-Fe and an hcp-Fe–Si alloy with 9 wt.% Si at 300 K up to∼ 170 and∼ 140 GPa, respectively. The results allow us …
High-pressure materials research has been revolutionized in the past few years due to technological breakthroughs in the diamond anvil cell (DAC), shock wave compression and …
