Geologic map of MTM quadrangles -15257 and -20257 of western Hesperia Planum, Mars
The volcanic edifice of Tyrrhena Patera (approximately -22°N, 252°W), Mars, stands 1800 m above the surrounding plains of Hesperia Planum, approximately 2000 km northeast of the center of the Hellas impact basin. Shallow ...
Identifying colloid-stabilizing forces in aqueous and non-aqueous media using atomic force microscopy and extended DLVO theory
The interfacial forces that dictate colloid stability in aqueous and non-aqueous systems are a function of the polar and apolar properties of the medium. This study quantifies these colloidal forces and energies between a ...
New models for geophysical mass flows
Granular flow is a common concept in studying geophysical mass flows. Volcanic avalanches, mud flows, landslides or debris flows can be considered to be granular flows or granular-fluid mixture flows. The range of scales ...
