A Subsolidus Olivine Water Solubility Equation for the Earth's Upper Mantle

, 2017
The pressure and temperature sensitivity of the two most important point hydrous defects in mantle olivine involving Si vacancies (associated to trace amounts of titanium [TiChu‐PD] or exclusively to Si vacancies [Si]) was investigated at subsolidus ...

Size effects resolve discrepancies in 40 years of work on low-temperature plasticity in olivine

Science Advances, 2017
When deforming by low-temperature plasticity, the strength of the mantle mineral olivine is controlled by its grain size. The strength of olivine at low temperatures and high stresses in Earth’s lithospheric mantle exerts a critical control on many ...

Hydration-reduced lattice thermal conductivity of olivine in Earth’s upper mantle

Proceedings of the National Academy of Sciences of the United States of America, 2017
Significance Thermal conductivity of mantle minerals is critical for controlling the temperature profile and dynamics of the mantle and subducting slabs. However, the effect of hydration on lattice thermal conductivity remains poorly understood.

Sustainable Reuse of FePO4 for Charged‐State Lithium Metal Battery with High Energy Density and Stable Cycle Performance

Advanced Energy and Sustainability Research, EarlyView.
In this study, heterosite FePO4 is obtained by chemical delithiation of LiFePO4 using O2. The extracted lithium source is recovered as lithium acetate, and the obtained FePO4 is used as an electrode for the charged‐state lithium metal battery (lean Li/FePO4 configuration), which shows stable cycling performance compared to the conventional lithium ...
