Summary: In this work, two novel compounds [Et3S][AuI4][I-5] (2) were synthesized by ionic liquid (IL) and applied as active layers in monolithic solar cells. These compounds are composed of tetraiodoaurate anions and polyiodide entities, with infinite polyiodide chains in 1 and pentaiodides in 2, resulting in relatively small electronic bandgaps. The deposition of gold iodide/polyiodide compounds onto porous monolithic substrates with subsequent solar cell characterization is demonstrated for the first time in this study. The devices show promising photovoltaic performance and offer new possibilities for materials design, moving away from lead-based photovoltaic materials. The use of simple polyiodide entities in this study enhances the structural and electronic dimensionality of gold perovskite-type anions.

Summary: Fullerene derivatives with hydrophilic substituents have been shown to exhibit various biological activities, including antiviral effects. Recent studies suggest that the anti-HIV activity of fullerene derivatives may not be solely attributed to their binding to HIV-1 protease, but could involve a novel mechanism related to viral genomic RNA packaging and HIV-1 cDNA synthesis, potentially affecting HIV-1 infectivity. Additionally, the oxidative activity and fluorescence quenching of fullerene derivatives might contribute to the diversity of reported anti-HIV-1 mechanisms.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
