KN 05 THE IMPORTANCE OF AEROSOL TRANSPORT IN LASER ABLATIONINDUCTIVELY COUPLED PLASMA –MASS SPECTROMETRY D. Günther, J. Koch, I. Kroslakova, J. Pisonero and M. Wälle ETH Zürich, Laboratory of Inorganic Chemistry, HCI Hönggerberg, G113, CH-8093 Zürich, Switzerland [email protected] The capabilities of laser ablation inductively coupled plasma mass spectrometry (LA-ICPMS) have been sign...
Sponges secrete a variety of mineral skeletons consisting of calcite, aragonite, and (or) amorphous silica that confer strength and protect them from physical perturbations. Calcification takes place in a solution of bicarbonate and calcium ions, which is supersaturated with respect to both calcite and aragonite. In contrast, siliceous spicules are formed from an environment that is undersatura...
Brittle materials fail by microcracking and fragmentation when subjected to multiaxial loading. In some cases full comminution occurs and the material behavior becomes governed by the flow of particles. In this work a granular model developed by Anand and co-workers, based on a two-mechanism elastoplastic formulation, is extended to include rate effects and incompressibility at zero void ratio....
