Modeling and monitoring injectivity evolution during cold CO2 injection with field evidence from aquistore carbon capture and storage operations

open access: yesDeep Underground Science and Engineering, EarlyView.
This work integrates 5 years of field data from the Aquistore CCS project with a non‐isothermal THM modeling framework to explain how cold CO2 injection alters injectivity over time. The study shows that sustained cooling near the wellbore reduces effective stresses, promotes tensile micro‑cracking, and leads to semi‑reversible permeability enhancement

Reusing depleted oil and gas wells for geothermal energy: Feasibility, challenges, and a decision‐making framework for sustainable conversion

open access: yesDeep Underground Science and Engineering, EarlyView.
The graphical abstract presents a structured decision‐support framework for assessing the feasibility of converting depleted oil and gas wells into geothermal energy systems. The left panel illustrates a comprehensive, multi‐stage decision‐making framework progressing from prefeasibility screening and technical–economic analysis to policy alignment ...

Morphology Engineering Derived CoOOH With Tunable Oxygen Vacancies for Potential‐Dependent Selective Electrooxidation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Through a morphology engineering strategy applied to CoFe PBA precursors, we successfully fabricated the CoOOH active phase enriched with oxygen vacancies and abundant edge sites. The introduced oxygen vacancies not only enhance the strong adsorption capacity for oxygen‐containing substrates but also suppress the overoxidation of HMFCA, thus enabling ...

Nucleophilic Reactions of Cyclobutenones and the Related 4,4‐Dichlorocyclobutenone Derivatives

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cyclobutenone derivates and their 4,4‐dichloro counterparts have an uninterrupted attention as useful synthons in the synthesis of complex organic molecules. Their nucleophilic reactions remain underexplored. This review brings attention to these reactions, whose outcome is not straightforward.

Emergent Atropisomerism Through Diels–Alder Reactions of Vinylallenes

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Cycloaddition‐induced geometric reorganization transforms achiral vinylallenes into atropisomeric styrenes. Conformational flexibility governs atropisomerization barriers, thermodynamic preferences, and configurational stability. Atropisomeric styrenes remain comparatively underdeveloped because configurational stability about the C(sp2)C(sp2) bond is
