The self-assembly of metal halide perovskite nanocrystals into micrometer-sized supercrystals with a high structural order as influenced by the surface chemistry and particle morphology of the starting building blocks is of interest for a broad spectrum of applications. In this work, we investigated the effects of Mn2+-doping CsPbBr3 perovskite nanocrys ...

The self-assembly of CsPbCl3 perovskite nanocrystals and their Mn2+-enriched analogs into supercrystals is reported. Increasing Mn2+ content in the nanocrystals leads to formation of larger, increasingly uniform cubic supercrystals that eventually become rod-like with higher photoluminescence quantum yields.

A library of 2,5-furan-based phenylene/thiophene oligomers were synthesized starting from 5-bromofurfural, a derivative of biomass-derived furfural. Varied electronic groups are coupled onto the furan motif, followed by the installation of a phenylene or thiophene central linker through a one-pot Pd-catalyzed decarboxylative cross-coupling reaction. Res ...

Superlattice formation afforded by metal halide perovskite nanocrystals has been a phenomenon of interest due to the high structural order induced in these self-assemblies, an order that is influenced by the surface chemistry and particle morphology of the starting building block material. In this work, we report on the formation of superlattices from a ...

Virtual reality (VR) may improve our understanding of sexual dysfunctions' manifestations, although research in this area remains limited. This study assessed the potential use of a VR Behavior Avoidance Test (VR-BAT) as a tool for examining the clinical features of Sexual Aversion Disorder (SAD): the experience of fear, disgust, and avoidance when ...

We report two photonic crystal-perovskite nanocrystal microbead hybrids with photoluminescence matching that of the parent nanocrystals but with increased photoluminescence quantum yields. Time-resolved photoluminescence spectroscopy quantifies the radiative enhancement afforded by the photonic environment of the microbeads. The reported hybrids also de ...
