Article Synopsis
  • Genetically encoded voltage indicators (GEVIs), especially those based on archaerhodopsin-3, are useful for visualizing changes in cell membrane potential.
  • To improve these tools, researchers aimed to create new GEVIs with better fluorescence and absorption properties.
  • The study successfully enhanced the fluorescence of archaerhodopsin-3 by stabilizing specific protein conformations through targeted mutations, leading to the design of new variants with a broader absorption range and significantly brighter emissions.

Controlling and understanding charge state and metal coordination in carbon nanomaterials is crucial to harnessing their unique properties. Here we describe the synthesis of the well-defined fulleride complex [{(nacnac)Mg}C], 2, (nacnac)=HC(MeCNMes), Mes=2,4,6-MeCH, from the reaction of the β-diketiminate magnesium(I) complex [{(nacnac)Mg}] with C in aromatic solvents. The molecular structure of complex 2 was determined, providing the first high-quality structural study of a complex with the C ion.

This work reports the one-pot synthesis of sterically demanding aniline derivatives from aryllithium species utilising trimethylsilyl azide to introduce amine functionalities and conversions to new examples of a common '-chelating ligand system. The reaction of TripLi (Trip = 2,4,6-Pr-CH) with trimethylsilyl azide afforded the silyltriazene TripNN(SiMe) in situ, which readily reacts with methanol under dinitrogen elimination to the aniline TripNH in good yield. The reaction pathways and by-products of the system have been studied.

Background: Therapy for type 1 diabetes mellitus (T1DM) is still largely an unsolved clinical problem. Despite the introduction into clinical practice of modern insulin preparations, devices for its administration, as well as continuous monitoring of glucose levels, the goals of therapy are often not achieved. At the same time, the International Diabetes Federation (IDF) notes an increase in the prevalence and incidence of T1DM in children and adolescents in the world.
