Monitoring spatially heterogeneous dynamics in a drying colloidal thin film [PDF]

, 2010
We report on a new type of experiment that enables us to monitor spatially and temporally heterogeneous dynamic properties in complex fluids. Our approach is based on the analysis of near-field speckles produced by light diffusely reflected from the ...

High silicon self-diffusion coefficient in dry forsterite

Earth and Planetary Science Letters, 2012
Silicon self-diffusion coefficients (DSi) in dry synthetic forsterite single crystals were measured at temperatures of 1600 and 1800 K, from ambient pressure up to 13 GPa using an ambient pressure furnace and Kawai-type multi-anvil apparatus. The water contents in the samples were carefully controlled at
