Step-Scan DSC Study on the Melting Behavior of Polypropylene/Attapulgite Nanocomposites
Attapulgite Melt Nano Composite Polypropylene (PP) Recrystallization
2011/11/22
Attapulgite(AT) was modified by grafting with butyl acrylate(BA) via polymerizations initiated by Gamma radiation. The polypropylene(PP)/AT nanocomposites were synthesized via melting extrude in a twi...
Hydrous, Low-carbon Melting of Garnet Peridotite
Hydrous Low-carbon Melting Garnet Peridotite
2014/4/8
The presence of volatile species in the Earth’s upper mantle drives
the formation of low-degree melts at pressures and temperatures
at which volatile-free mantle rocks would be subsolidus. The two

A hydrous melting and fractionation model for mid-ocean ridge basalts: Application to the Mid-Atlantic Ridge near the Azores
A hydrous melting mid-ocean ridge basalts
2014/4/8
The major element, trace element, and isotopic composition of mid-ocean ridge basalt glasses affected
by the Azores hotspot are strongly correlated with H2O content of the glass. Distinguishing the r...
Loss of iron to gold capsules in rock-melting experiments
Loss iron gold capsules rock-melting experiments
2012/4/1
Gold is used widely for capsules in high-temperature rock-melting studies because it is generally
thought to absorb negligible Fe from silicate samples. However, we observed significant losses of Fe
