Nano Letters

We employ glass microtube structures fabricated by rolled-up nanotechnology to infer the influence of scaffold dimensionality and cell confinement on neural stem cell (NSC) migration. Thereby, we observe a pronounced morphology change that marks a re

Cerium oxide nanoclusters: commensurate with concepts of polyoxometalate chemistry?

Autor: Arkady Ellern, Svetlana G. Baca, Paul Kögerler, Iurii L. Malaestean

Publikováno v: Chemical communications 48, 1499-1501 (2012). doi:10.1039/c1cc14725k

The mixed-valent cerium(III/IV) oxide clusters {Ce(10)} and {Ce(22)}, derived from condensation reactions of cerium carboxylate coordination polymers, exhibit molecular growth tendencies similar to those of 'classical' group V and VI polyoxometalates
