Generalized molecular solvation in non-aqueous solutions by a single parameter implicit solvation scheme
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 single fit parameter and thereby largely reducing statistical noise.

Absorption and emission modulation in a MoS2–GaN (0001) heterostructure by interface phonon–exciton coupling
Article reporting the change in the transient absorption characteristics of monolayer MoS2 and the modified PL emission characteristics in a monolayer MoS2–GaN (0001) heterostructure due to the coupling of carriers with the phonon modes and the energy exchange at the interface. The results demonstrate the relevance of interface coupling between the semiconductors for the development of optical and electronic applications.

Single-Step Photochemical Formation of Near-Infrared-Absorbing Gold Nanomosaic within PNIPAm Microgels: Candidates for Photothermal Drug Delivery
Article demonstrating the dynamic potential for tailoring the surface plasmon resonance (SPR), size, and shapes of gold nanoparticles (AuNPs) starting from an Au(I) precursor, chloro(dimethyl sulfide)gold (I) (Au(Me2S)Cl), in lieu of the conventional Au(III) precursor hydrogen tetrachloroaurate (III) hydrate (HAuCl4). This approach presents a one-step method that permits regulation of an Au(I) precursor to form either visible-absorbing gold nanospheres or near-infrared-window (NIRW)-absorbing anisotropic AuNPs.

A Statistical Analysis of Trans-Resveratrol in Grape Cane From Ten Varieties of Cultivated Wine Grapes (Vitis Spp.)
This article isolated resveratrol by a non-optimized protocol from ten varieties of grape cane grown in central Texas, USA. A statistical grouping of the ten varieties suggests that Norton, Blanca du bois, Cabernet Sauvignon, and Lenoir are the best candidates to use for further resveratrol isolation.
