Proton reduction by phosphinidene-capped triiron clusters (open access)

Proton reduction by phosphinidene-capped triiron clusters

This article prepares and examines Bis(phosphinidene)-capped triiron carbonyl clusters, including electron rich derivatives formed by substitution with chelating diphosphines as proton reduction catalysts.

Spatial and temporal localization of SPIRRIG and WAVE/SCAR reveal roles for these proteins in actin-mediated root hair development (open access)

Spatial and temporal localization of SPIRRIG and WAVE/SCAR reveal roles for these proteins in actin-mediated root hair development

Article shows that SPIRRIG (SPI), a beige and Chediak Higashi domain-containing protein involved in membrane trafficking, and BRK1 and SCAR2, subunits of the WAVE/SCAR (W/SC) actin nucleating promoting complex, display polarized localizations in Arabidopsis thaliana root hairs during distinct developmental stages. Authors' work uncovers a role for SPI in facilitating actin-dependent root hair development in Arabidopsis through pathways that might intersect with W/SC.

Excited State Charge Separation in an Azobenzene-Bridged Perylenediimide Dimer – Effect of Photochemical Trans-Cis Isomerization (open access)

Excited State Charge Separation in an Azobenzene-Bridged Perylenediimide Dimer – Effect of Photochemical Trans-Cis Isomerization

Article demonstrating photoinduced charge transfer and separation events in a newly synthesized azobenzene-bridged perylenediimide-dimer (PDI-dimer). Results offer key insights on the role of the azobenzene bridge and the dimer geometry in governing the excited state charge transfer and separation in symmetrically linked PDI dimer.
