Evaluating the host potential of 9,9’-bifluorenyl-9,9’-diol for anisole and the three methylanisole isomers, and its behaviour in mixed guest solutions

Although 9,9'-bifluorenyl-9,9'-diol (H) demonstrates the ability to enclathrate anisole and its three methylanisole isomers, its inability to selectively separate anisole from mixtures and the prevalence of crystallographic disorder in most complexes limit its utility as a separation agent, with thermal and structural data suggesting a specific preference for 4-methylanisole driven by stable host-guest interactions.

A Universal Size-dependent Law for Photocatalysis in Organic Nanocrystals

This study introduces an Ostwald-ripening-induced strategy to fabricate ultrasmall Y6 organic nanocrystals (4–220 nm), revealing a universal size-dependent law where reducing crystal diameter exponentially enhances exciton dissociation and photocatalytic hydrogen evolution rates, achieving record performance in single-component organic photocatalysts.

Overall Performance of Hemicellulose/PLA Blends after Sanitizing and Soil Exposures

This study demonstrates that solvent-molded films composed of polylactic acid (PLA) and hemicellulose, compatibilized with 10 wt% citric acid, achieve an optimal balance of mechanical strength and flexibility while significantly accelerating environmental degradation through increased crystallinity after exposure to water and soil.

Enhancing Spectral Absorption of Organic Dye Sensitizers through ZnSO₄‑Mediated Coordination and Protonation for DSSCs Applications

This study demonstrates that incorporating a ZnSO₄ dual-functional additive enhances the performance of anthocyanin-based dye-sensitized solar cells by utilizing Zn²⁺ coordination and SO₄²⁻-mediated protonation to stabilize the flavylium cation, thereby improving spectral absorption and increasing power conversion efficiency from 0.11% to 0.38%.
