TL;DR: A six-stage amphoteric redox hydrocarbon radical with three phenalenyl units was presented in this paper, which exhibits six reversible redox waves with a small numerical sum (E1sum).
Abstract: A six-stage amphoteric redox hydrocarbon radical 3• containing three phenalenyl units was prepared. Cyclic voltammogram of 3• exhibits six reversible redox waves with a small numerical sum (E1sum) ...

TL;DR: Tetra-tert-butyl-as-indaceno [1,2,3-cd:6,7,8-c′d′]diphenalene (TTB-asIDPL) was prepared and found to behave as a four-stage amphoteric redox compound as mentioned in this paper.

TL;DR: In this article, a triangulene derivative (3), the first non-Kekule polynuclear aromatic hydrocarbon, was generated by oxidizing a corresponding precursor in a toluene solution by p-chloranil.

TL;DR: In this article, a novel experimental approach has been employed for the measurement of delayed protons from the fragmentation of a ${}^{28}\mathrm{Si}$ beam with an energy of 100 MeV/nucleon.
Abstract: A novel experimental approach has been employed for the measurement of $\ensuremath{\beta}$-delayed protons from ${}^{24}\mathrm{Si}$ produced via the fragmentation of a ${}^{28}\mathrm{Si}$ beam with an energy of 100 MeV/nucleon. The secondary beam of ${}^{24}\mathrm{Si}$ was separated by the projectile fragment separator RIPS at RIKEN and was implanted in a 2.6 $\ensuremath{\mu}\mathrm{m}$ aluminum foil placed parallel to a gas-$\ensuremath{\Delta}E$ and silicon-$E$ detector telescope for the measurement of delayed protons. The above arrangement has led to a very clean, $\ensuremath{\beta}$-ray background free delayed proton energy spectra and a few new proton peaks could be identified from the decay of ${}^{24}\mathrm{Si}.$
