(1) Upper sorted suevite (794.63 – 807.75 m) and (2) Lower sorted suevite (807.75 – 823.25 m): The dominating component in both units of the sorted suevite are melt particles of shock stage IV. Two different textural types of melt particles were observed: (1) brownish to pale green silicate melt particles with flow texture, vesicles and schlieren; and (2) dark aphanitic particles with inclusion...

– We propose that several mechanisms contribute to friction in a polymer melt adsorbed at a structured surface. The first one is the well known disentanglement of bulk polymer chains from the surface layer. However, if the surface is ideal at the atomic scale, the adsorbed parts of polymer chains can move along the equipotential lines of the surface potential. This gives rise to a strong slippa...

Recent geochemical studies of MORB genesis suggest that at least some degree of chemical disequilibrium occurs during the transport of magma to the surface. If disequilibrium transport does occur in the mantle, it would seem to preclude melt being distributed in a porous network on grain boundaries that could rapidly re-equilibrate with the solid. The questions remain however, as to how big a m...

A multi-scale phase-field approach, which couples the mesoscopic crystallization with the microscopic orientation of chain segments and macroscopic viscoelastic melt flow, is proposed to study how the crystal growth of semi-crystalline polymers is affected by flows. To make the simulation feasible, we divide the problem into three parts. In the first part, a finitely extensible nonlinear elasti...

Changes to the dynamics of the Greenland ice sheet can be forced by various mechanisms including surface-melt-induced ice acceleration and oceanic forcing of marine-terminating glaciers. We use observations of ice motion to examine the surface melt-induced dynamic response of a land-terminating outlet glacier in southwest Greenland to the exceptional melting observed in 2012. During summer, mel...

Numerical simulation is a comprehensive tool in modern process development which is extensively used for promotion of crystal growth processes. Multi-crystalline silicon is an important material with advantages of low-production cost and high conversion efficiency of PV solar cells. The control of grains as well as the grain boundaries is particularly important to the crystal quality and thus t...

[1] Subduction zone magmas are characterized by high concentrations of H2O, presumably derived from the subducted plate and ultimately responsible for melting at this tectonic setting. Previous studies of the role of water during mantle melting beneath back-arc basins found positive correlations between the H2O concentration of the mantle (H2Oo) and the extent of melting (F), in contrast to the...

The process of fluidized bed spray granulation unites the steps of solid formation and product formulation in one apparatus and is used to produce granules out of a liquid. Thereby, a melt is atomized into small droplets and sprayed into the fluidized bed, which consists of seed particles of the same material. Droplets deposit on the particles near the spray zone and form a film which solidifie...
