Critical Shear Stress for Erosion of Sand-Mud Mixtures and Pure Mud
The erosion threshold of sand-mud mixtures is investigated by analyzing the momentum balance of a sand particle or a mud parcel in the mixture bed surface, and a formula for the critical shear stress ...

Direct Observation of Palladium Leaching from Pd/C by a Simple Method: X-ray Absorption Spectroscopy of Heterogeneous Mixtures
The intensity of the background absorption increased in the order xylene < DMAc < THF < water, consistent with the concentration of oxygen atoms which have a relatively high X-ray interaction. Since ...
