Rock mechanical properties under reconstructed deep in situ thermo–hydro–mechanical conditions: Implications for CO₂‐related injection scenarios

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates a reconstructed in situ thermo‐hydro‐mechanical (THM) framework in which porosity serves as the central variable linking stress, pore pressure, and temperature to evolving mechanical properties of rocks. Under burial conditions, in situ stress, pore pressure, and temperature jointly govern volumetric strain and ...

Copper Complexes with Arylated Triethylenetetramine Ligands: Reactivity Toward Dioxygen and Peroxides

European Journal of Inorganic Chemistry, EarlyView.
Here, we describe new Cu(I)/Cu(II) complexes based on arylated tren ligands and investigate their reactivity toward O2 and peroxides. Low‐temperature–stopped flow studies revealed the formation of transient copper–oxygen species, including superoxido, hydroperoxido, and alkylperoxido intermediates.

Enabling Ultrastable Microbubbles With Graphene Aerogel Enrichment and Machine Learning for Highly Efficient Carbon Storage

Electron, EarlyView.
This study aims to introduce a novel‐designed structure of the colloidal aphron microbubbles reinforced by incorporating hydrophobic aerographene microparticles onto the hydrophobic outer shell. This results in the formation of a robust composite film and armored microbubble that offers exceptional ultrastability under elevated pressures of up to 400 ...
