The Determination of the Activities in Mn-C and Mn-Si Melts

The activities of manganese in Mn-C and Mn-Si melts at 1673K have been determined. The transportation method was applied to the vapor pressure measurement. The activities of manganese in the Mn-C melts as referred to pure liquid manganese showed the positive deviation from ideality at less than 0.17 atomic fraction of carbon and deviated negatively above this value. The activities of manganese ...

Nanoparticle Dynamics in Polymer Melts

Reaction Kinetics in Polymer Melts

We study the reaction kinetics of end-functionalized polymer chains dispersed in an unreactive polymer melt. Starting from an infinite hierarchy of coupled equations for many-chain correlation functions, a closed equation is derived for the 2nd order rate constant k after postulating simple physical bounds. Our results generalize previous 2-chain treatments (valid in dilute reactants limit) by ...

H2O diffusion in dacitic melts

We report the first experimental study of the diffusion of H2O in dacitic melts. Dehydration experiments were conducted at 551–637 8C and 1–1450 bars for samples with ~0.8 to ~2.5 wt.% total dissolved H2O. The H2O diffusivity is proportional to total H2O contents at V0.8 wt.%, but increases exponentially with total H2O at higher H2O contents. The diffusivity of the total dissolved H2O (in Am /s...

MelTS Melody Translation System

MelTS is an automatic harmonization system that creates multi-part arrangements in the style of the data on which it was trained. The system approaches the problem of harmonization from a machine tranlsation perspective, modeling the melody of a song as the source language and each harmony as a target language. The approach stands in contrast to previous approaches to the harmonization problem,...
