A colorless, odorless, flammable gas that is the simplest of the hydrocarbons, having the formula CH4. It is the major constituent of natural gas and is released during the decomposition of plant or other organic compounds, as in marshes and coal mines. ...

The carbonated “solidus ledge” is a relatively narrow boundary in the lithospheric mantle capable of an abrupt immobilisation of fluxing or transported carbonated melts. The investigated rocks are estimated to store approximately 0.02 kg C/m3 (or 6 ppm C) occurring as carbonates in the MSI....
Another key challenge is the development of an effective, low-cost system for the mass production of MXenes on large-scale [10,11,34,35]. This will not only expand the applications of MXenes in various fields but will also be a major step towards their commercial applications and solving ...
100 m below the ground surface. Assessment of groundwater behavior at such depths is important in geoscience since depth of well screens for water abstraction is typically < 100 m below ground level (BGL) in the major European and American industrial cities (De Simone2008; Tellam and Barker...
‘manufacture’ of hydrogen as a transport fuel. Another source of hydrogen is, however, available and could provide a supply pending the development of more efficient and cheaper renewable energy technologies. By splitting natural gas (methane) into its constituent parts, hydrogen and carbon dioxide...
“BSOA-driven feedback” has been suggested to form a negative climate feedback particularly in the wide boreal forest regions where BSOA is an important constituent of ambient aerosol and influence of anthropogenic pollution is low14,15. There, the emissions of the main BSOA precursors, ...
(Fig.S11). This internal texture is consistent with formation via cooling of melts. In this case, the melts are dominated by Pb, which was a major constituent of the featherbeds used at Taranaki18.CeresIshows no evidence of weathering, butCeresIIIdisplays a thin (5–10 µm thick) rim ...
Thomas Graham (1805-1869) is known as the founder of colloidal chemistry and for his fundamental research on the nature of phosphoric acid and phosphates, diffusion of gases, liquids, and solutions, adsorption of gases by metals, dialysis, osmosis, mass transfer through membranes, and the constit...
and induced by the circulation of high-temperature hydrothermal fluids51. Clinopyroxene (diopside in particular) is normally a major constituent in skarns55,91and can be formed by contact metamorphism at global continental arcs that are long-term storage sites for sedimentary carbonates50. The diopsi...
