The impact of Himalayan-Tibetan erosion on silicate weathering and organic carbon burial
Chemical GeologyCenozoic mountain building in Asia has been proposed as an important control over global climate by atmospheric CO 2 drawdown through silicate weathering and burial of organic carbon (OC) offshore. Because Asian submarine fans represent the most complete

Old carbon contributes to aquatic emissions of carbon dioxide in the Amazon [PDF]
, 2014 Knowing the rate at which carbon is cycled is crucial to understanding the dynamics of carbon transfer pathways. Recent technical developments now support measurement of the <sup>14</sup>C age of evaded CO<sub>2</sub> from fluvial

Predicting Water Cycle Characteristics from Percolation Theory and Observational Data. [PDF]
, 2020 The fate of water and water-soluble toxic wastes in the subsurface is of high importance for many scientific and practical applications. Although solute transport is proportional to water flow rates, theoretical and experimental studies show that heavy ...

Rates of sustainable forest harvest depend on rotation length and weathering of soil minerals [PDF]
, 2014 Removals of forest biomass in the northeastern US may intensify over the coming decades due to increased demand for renewable energy. For forests to regenerate successfully following intensified harvests, the nutrients removed from the ecosystem in the ...

Advanced Science, EarlyView.Metal‐ion‐coupled self‐assembled layered gels were prepared using a simple sol–gel method, successfully integrating electromagnetic shielding and thermochromic functions into the material. SCa‐1, which exhibits the best overall performance, achieves an electromagnetic shielding efficiency of up to 72.49 dB, while maintaining a visible light ...

Surface hydration‐induced damage in tight oil‐bearing sandy conglomerate reservoirs
Deep Underground Science and Engineering, EarlyView.A series of techniques such as X‐ray diffraction, scanning electron microscopy, energy‐dispersive spectroscopy, conductivity tests, and infrared thermal imaging were used. The key findings are the identification of a two‐stage surface hydration process and the elucidation of the effects of various minerals and elements on the hydration process ...

Direct evidence for atmospheric carbon dioxide removal via enhanced weathering in cropland soil
Environmental Research Communications, 2023 Enhanced weathering of soil-applied crushed silicate rocks may remove substantial atmospheric carbon dioxide; however, field testing of this negative emission technology is lacking.

The contribution of weathering of the main Alpine rivers on the global carbon cycle [PDF]
, 2013 On geological time-scales the carbon fluxes from the solid Earth to the atmosphere mainly result from volcanism and metamorphic-decarbonation processes, whereas the carbon fluxes from atmosphere to solid Earth mainly depend on weathering of silicates and
