Multiterminal Josephson junctions (MTJJs), devices in which a normal metal is in contact with three or more superconducting leads, have been proposed as artificial analogs of topological crystals. The topological nature of MTJJs manifests as a modulation of the quasiparticle density of states (DOS) in the normal metal that may be probed by tunneling measurements. We show that one can reveal this modulation by measuring the resistance of diffusive MTJJs with normal contacts, which shows rich structure as a function of the phase differences {ϕ_{i}}.

- - The study discusses the creation of three indium complexes (1-3) using different chelating ligands (L1-L3), which were analyzed through multinuclear NMR and confirmed by single-crystal X-ray crystallography.
- - Indium complex 1, when combined with phenylsilane and NaI, efficiently reduces nitroarenes into amines, achieving good yields.
- - The reduction process is effective for nitroarenes with various functional groups under standard reaction conditions.
The COCONUT (COlleCtion of Open Natural prodUcTs) database was launched in 2021 as an aggregation of openly available natural product datasets and has been one of the biggest open natural product databases since. Apart from the chemical structures of natural products, COCONUT contains information about names and synonyms, species and organism parts in which the natural product has been found, geographic information about where the respective sample has been collected and literature references, where available. COCONUT is openly accessible at https://coconut.

Triarylboron compounds have been established as promising candidates in optoelectronic applications. However, realizing multi-functional properties in triaryl boron-based materials remains challenging. Herein, we present two regioisomers, 1 and 2, designed judiciously by connecting a dimethylamino donor and a dimesitylboryl acceptor at 1,4 and 2,6-positions of the naphthalene spacer, respectively.

- The study focuses on synthesizing various bis-amidinate indium(III) monochlorides by reacting specific Li-amidinate ligands with InCl.
- Single crystal X-ray analysis shows that these compounds feature an In(III) center coordinated with two amidinate ligands, creating a distorted trigonal bipyramidal geometry.
- The photophysical properties of these compounds were examined, revealing that they are emissive in solution, with the 9-anthryl compound achieving a quantum yield of 45.5% and a lifetime of 11 ns in dichloromethane.
