Acoustically optimal state points for constraining CCS mixture models in the metering-critical region of CO₂ + N₂, O₂, and Ar

This paper identifies a critical lack of acoustic data in the metering-critical region for CO₂-rich CCS streams and proposes a statistically optimized measurement campaign of 48 points per binary system to significantly improve the constraints on mixture model parameters, revealing that composition realization rather than acoustic measurement is the primary limiting factor for achieving high-precision model validation.

Homologative Electrochemical Installation of Unprotected Functionalities Across Alkenes

This paper reports an operationally simple electrochemical "masking–unveiling" strategy that enables the homologative installation of multiple unprotected heteroatom functionalities across diverse alkenes to synthesize 1,3-hetero-functionalized amines and 1,4-amino alcohols via a selective 4e⁻/4H⁺ process involving redox-active intermediates.

COF-5-based TiO₂ and AuNP composites for UV/H₂O₂-assisted photocatalytic degradation of 4-nitrophenol

This study demonstrates that COF-5-based composites, particularly TiO₂@COF-5, significantly enhance the UV/H₂O₂-assisted photocatalytic degradation of 4-nitrophenol by improving substrate accessibility and charge-transfer efficiency compared to individual components.

Effective diffusion in sharp-front reactive transport experiments

This study presents a closed-form analytical solution for sharp-front reactive transport in porous media, demonstrating that the experimentally inferred effective diffusion coefficient fundamentally differs from the intrinsic molecular diffusion coefficient due to coupled advection-diffusion-thermodynamic effects, a framework validated through Portland cement carbonation experiments under various flow conditions.
