Symmetry breaking charge transfer leading to charge separation in a far-red absorbing bisstyryl-BODIPY dimer

Description: Article describes how symmetry breaking charge transfer is one of the important photo-events occurring in photosynthetic reaction centers that is responsible for initiating electron transfer leading to a long-lived charge-separated state and has been successfully employed in light-to-electricity converting optoelectronic devices. In this study, the authors report a newly synthesized, far-red absorbing and emitting BODIPY-dimer to undergo symmetry-breaking charge transfer leading to charge-separ… more

The chemical coupling between moist CO oxidation and gas-phase potassium sulfation

Description: Article discusses how the chemical coupling between moist CO oxidation and transformation of gaseous potassium salts (KCl or KOH) in the presence and absence of SO2 was investigated experimentally and through chemical kinetic modeling. Analysis of the calculations indicates that sulfation pathways in the model involving KOSO3 contribute to the overprediction, but both the thermodynamic properties and rate constants in the model involve significant uncertainties and more work is required to reso… more

The Crucial Role of Solvation Forces in the Steric Stabilization of Nanoplatelets

Description: Article says that the steric stability of inorganic colloidal particles in an apolar solvent is usually described in terms of the balance between three contributions: the van der Waals attraction, the free energy of mixing, and the ligand compression. The authors demonstrate that for sufficiently large nanoplatelets, solvation forces are proportional to the interacting facet area, and their strength is intrinsically tied to the softness of the ligand shell.

Generalized molecular solvation in non-aqueous solutions by a single parameter implicit solvation scheme

Description: Article presenting a systematic parametrization protocol for the Self-Consistent Continuum Solvation (SCCS) model resulting in optimized parameters for 67 non-aqueous solvents. The parametrization is based on a collection of ≈6000 experimentally measured partition coefficients, which were collected in the Solv@TUM database presented here. The accuracy of the optimized SCCS model is comparable to the well-known universal continuum solvation model (SMx) family of methods, while relying on only a … more
