In addition to high concentrations of CH4 and H2, abundant dissolved N2 is found in subsurface fracture fluids in Precambrian cratons around the world. These fracture fluids have hydrogeological isolation times on order of thousands to millions and even ...

Sulfur metabolisms in epsilon- and gamma-Proteobacteria in deep-sea hydrothermal fields
In deep-sea hydrothermal systems, super hot and reduced vent fluids from the subseafloor blend with cold and oxidized seawater. Very unique and dense ecosystems are formed within these environments.

The main geodynamic border and seismic visualization of plumes under the East European Platform
According to the Taylor approximation method of the three-dimensional P-velocity mantle model under Eurasia, a seismic imaging of the manifold plumes and super-deep fluid processes of the East European Platform was carried out.

Instabilities in relativistic two-component (super)fluids
We study two-fluid systems with nonzero fluid velocities and compute their sound modes, which indicate various instabilities. For the case of two zero-temperature superfluids we employ a microscopic field-theoretical model of two coupled bosonic fields ...

Implications of ideas on super-hydrophobicity for water repellent soil [PDF]
Water repellence is an important factor in soil erosion due to its role in inhibiting the re-establishinent of vegetation after fire and due to its enhancement of run-off.

Experimental Study of Matrix Permeability of Gas Shale: An Application to CO2-Based Shale Fracturing
Because the limitations of water-based fracturing fluids restrict their fracturing efficiency and scope of application, liquid CO2 is regarded as a promising substitute, owing to its unique characteristics, including its greater environmental ...
