Decoupling Redox Potentials and Excited State Energies in Substituted Chromium(III) Chromophores

open access: yesChemistry – A European Journal, EarlyView.
Redox and excited state properties of organic and precious metal CT photocatalysts are strongly entangled. In contrast, redox potentials of polypyridine chromium(III) complexes, that feature purely metal‐centered SF states, are selectively tuned by incremental substituent effects of the CF3 group, while excited state energies and lifetimes remain ...

Local sensitivity analysis of a supercritical extraction model

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract This study investigates the process of chamomile oil extraction from chamomile flowers. A parameter‐distributed model, consisting of a set of partial differential equations, was used to describe the governing mass transfer phenomena between solid and fluid phases under supercritical conditions using carbon dioxide as the solvent.

eChem: Accelerated Method Development in Quantum Chemistry with Notebooks

open access: yesChemistry–Methods, EarlyView.
The benefits of using Jupyter Notebooks to simplify and accelerate scientific code development are demonstrated using the practical example of the analytical molecular Hessian. The eChem project has been previously presented as an interactive platform for quantum and computational chemistry education [J. Chem. Educ. 100, 1664–1671].

A New Method for Skin Color Classification Based on Global CIELAB Data and k‐Mean Clustering

open access: yesColor Research &Application, EarlyView.
The six skin color clusters. ABSTRACT Human skin color varies significantly across the globe, presenting a challenge for accurate and objective classification. Existing systems, like the Fitzpatrick Skin Type (FST) and individual typology angle (ITA), are primarily designed to assess photosensitivity and fail to capture the full spectrum of skin color ...
