Montoya-Moreno N, Seijas L, Flores-Gaspar A, Torres F, Ali-Torres J
RSC Adv . 2024 Dec; 14(51):38153-38161. PMID: 39624430
Free radicals such as superoxide are reactive species that, upon accumulation, lead to oxidative stress. The superoxide dismutase (SOD) enzyme mitigates this stress by converting superoxide into hydrogen peroxide and...

Seijas L, Almeida R, Rincon L, Zambrano C, Rodriguez V, Merino G, et al.
Phys Chem Chem Phys . 2023 Nov; 25(48):32922-32930. PMID: 38018412
This work delves into the bonding nature of the pentagonal-pyramidal benzene and hexamethylbenzene dications, CR (R = H and CH), which contain a hexacoordinate carbon. The study employs a range...
