Characterization of Binary Hydrates Containing Methane by X-ray Diffraction and Microscopic Laser Raman Spectroscopy

Yankuang ceshi, 2021
BACKGROUND The crystal structure of natural gas hydrate mainly depends on the species and composition of guest molecules. At present, the structure and spectral characteristics of single-component hydrate are relatively clear, but the studies of multi ...

Escape of methane gas from the seabed along the West Spitsbergen continental margin [PDF]

, 2009
More than 250 plumes of gas bubbles have been discovered emanating from the seabed of the West Spitsbergen continental margin, in a depth range of 150-400 m, at and above the present upper limit of the gas hydrate stability zone (GHSZ).

Diverse gas composition controls the Moby-Dick gas hydrate system in the Gulf of Mexico [PDF]

, 2021
In marine basins, gas hydrate systems are usually identified by a bottom simulating reflection (BSR) that parallels the seafloor and coincides with the base of the gas hydrate stability zone (GHSZ).

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy

Advanced Engineering Materials, EarlyView.
Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).
