Explants were taken out 4 and 8 weeks after in vivo implantation and fixed in 4% PFA for subsequent nano-CT and histological analysis. Moreover, the Valence Shell Electron Pair Repulsion (VSEPR) theory, says the molecular geometry of a molecule is trigonal planar if the bond angle is 120° or . HNCO and HOCN, on the other hand, are rather formed through ion molecule schema as products in the dissociative recombination of H 2 NCO + and HNCOH +, although the reaction for the latter has not yet been studied in the laboratory. CI SCH lutc lth (c) HOCN H-O-CENA.
