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

Color 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 ...

Probing the Hybrid σ/π‐Holes in sp2‐Hybridized Chalcogen Bond Donors and their Complexes with Ammonia

ChemPhysChem, EarlyView.
A double‐bonded chalcogen bond donor exhibits both a σ‐hole and a π‐hole on the same atom. These unique σ/π‐holes can be tuned based on molecular composition to be directional or semidirectional depending on the donor–acceptor bonding configuration, which differs from the behavior of other electropositive holes.

Solvent Effects on the Selectivity of Ambimodal Dipolar/Diels–Alder Cycloadditions: A Study Using Explicit Solvation Models

ChemPhysChem, EarlyView.
Post‐transition state bifurcation in the reaction of 2‐aminoacrolein with 1,3‐butadiene is investigated using explicit solvation (up to 45 water molecules). GFN2‐xTB dynamics reveal strong solvent‐size effects on branching to (4 + 2) and (4 + 3) cycloadducts via an ambimodal transition state.

Low‐Viscosity Concentrated Lithium Chloride Solution with Unsymmetrical Ditopic Receptors in Organic Solvents

ChemPhysChem, EarlyView.
A low viscosity and highly concentrated solution of LiCl can be prepared using ditopic receptors bearing different terminal substituents on urea moieties linked by ether groups in organic solvents. The solution shows improved ionic conductivity due to the low viscosity, as well as suppression of solidification compared to solutions with symmetrical ...
