63“…Moreover, we also observed that the surface oxygen vacancies upregulated the mineralization of human mesenchymal stromal cells (hMSCs) on rutile TiO(2) nanorod substrates. …”

64por Yang, Zhenzhong, Wang, Le, Dhas, Jeffrey A., Engelhard, Mark H., Bowden, Mark E., Liu, Wen, Zhu, Zihua, Wang, Chongmin, Chambers, Scott A., Sushko, Peter V., Du, Yingge“…In this work, using in-situ transmission electron microscopy, we directly show that oxygen ion migration in vacancy ordered, semiconducting SrFeO(2.5) epitaxial thin films can be guided to proceed through two distinctly different diffusion pathways, each resulting in different polymorphs of SrFeO(2.75) with different ground electronic properties before reaching a fully oxidized, metallic SrFeO(3) phase. …”

66“…The atomic geometries and transition levels of point defects and substitutional dopants in few-layer and bulk black phosphorus are calculated. The vacancy is found to reconstruct in monolayer P to leave a single dangling bond, giving a negative U defect with a +/− transition level at 0.24 eV above the valence band edge. …”

67“…The nucleation of nanoclusters starts from the O-enriched solute clustering with vacancy mediation. The nanoclusters grow with an extremely low growth rate through attraction of vacancies and O:vacancy pairs, leading to the unusual stability of the nanoclusters.…”
