In-situ abiogenic methane synthesis from diamond and graphite under geologically relevant conditions
Using diamond anvil cell and high temperature experiments, this work proves that the interaction between deep hydrogen rich fluids and reduced carbon minerals may be an efficient mechanism for producing abiotic hydrocarbons at the upper mantle’s ...

Calibration of Manganin pressure gauge for diamond-anvil cells [PDF]
Pressure calibration for most diamond-anvil cell (DAC) experiments is mainly based on the ruby scale, which is key to implementing this powerful tool for high-pressure study. However, the ruby scale can often hardly be used for programmably controlled DAC devices, especially the piezoelectric-driving cells, where a continuous pressure calibration is ...

Simultaneous imaging and diffraction in the dynamic diamond anvil cell
The ability to visualize a sample undergoing a pressure-induced phase transition allows for the determination of kinetic parameters, such as the nucleation and growth rates of the high-pressure phase. For samples that are opaque to visible light (such as metallic systems), it is necessary to rely on x-ray imaging methods for sample visualization. Here,

Neutron diffraction in diamond anvil cells [PDF]
Neutron diffraction provides many unique advantages for structural studies of materials under extremes of pressure. In addition to the famous sensitivity to light atom positions, neutrons are sensitive to long-range magnetic order and have an extremely high spatial resolution. However, a major downside of neutron techniques, that is keenly felt in high
