Advanced Science, Volume 12, Issue 32, August 28, 2025.Novel mixed‐matrix carbon molecular sieve (MMCMS) membranes are fabricated via employing palladium‐doped carboxyl‐functionalized UiO‐66 (Pd/UiO66‐COOH)/polyimide MMM as precursor. The synergistic effect of decarboxylation‐induced thermally cross‐linking and catalytic graphitization of Pd promoted the formation of more ordered Langmuir domains, thereby ...

Energy Science &Engineering, Volume 13, Issue 8, Page 4114-4130, August 2025.ABSTRACT The deep coal seams in the Pingdingshan mining area are characterized by high stress and low adsorption capacity. Existing water injection additives have proven ineffective in preventing dynamic disasters. Research has found that IDS (iminodisuccinic acid tetrasodium salt) can dissolve minerals in coal, significantly improving the connectivity

Documented international enquiry on solid sedimentary fossil fuels; Coal: definitions, classifications, reserves-resources and energy potential [PDF]
, 2002 This paper deals with all solid sedimentary fossil fuels, i.e. coal, the main one for geological reserves and resources, peat, and oil shales. Definitions of coal ( < 50% ash) and coal seam (thickness and depth limits) are examined in view of an ...

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.Abstract Subsurface wastewater injection has increased the seismicity rate within the Raton Basin over more than two decades, with the basin‐wide injection rate peaked between 2009 and 2015. To understand the evolution of injection‐induced earthquakes, we systematically analyzed 2016–2024 broadband recordings with a machine‐learning‐based phase picker ...
