High pressure and temperature spinning capillary cell for in-situ synchrotron X-ray powder diffraction
(2019)
In situ research of materials under moderate pressures (hundreds of bar) is essential in many scientific fields. These range from gas sorption to chemical and biological processes. One industrially important discipline is ...
Ptychographic X-ray computed tomography analysis of cement pastes
(2019-10-04)
Ptychographic X-ray computed tomography provides 3D electron mass density and attenuationcoefficient distributions of unaltered cement pastes with an isotropic resolution below 100 nm. Thisimaging technique allows ...
Alite hydration mechanism in presence of ye’elimite related to BAY cements
(2019-10-08)
One alternative to decrease CO2 emissions from ordinary Portland Cement (OPC) production consists
on the development of a new kind of eco-cements composed by less calcite demanding phases. That is
the case of ...
Synchrotron X-ray pair distribution function analysis of tricalcium silicate pastes
(2019-09-24)
The analysis of nanocrystalline and amorphous components within cement pastes that contain high amounts of crystalline phases is very challenging. Synchrotron powder diffraction jointly with the pair distribution function ...
