Structural and Luminescent Properties of Micro- and Nanosized Particles of Lanthanide Terephthalate Coordination Polymers

Reaction in water between rare earth ions (Ln ) Y, La-Tm, except Pm) and the sodium salt of terephthalic acid leads to a family of lanthanide-based coordination polymers of general formula [Ln2(C8H4O4)3(H2O)4]n with Ln ) La-Tm or Y. The isostructurality of ...

All the Disorder Mechanisms in the 13:58 Phases Come Together. Out of the Modulated Confusion Rises the Remarkable Phase Ce12.60Cd58.68(2)

The compound

Ce_{12.60}Cd_{58.68(2)}

is a metrically commensurate representative of the incommensurately modulated phase

Ce_{13}Cd_{57+\delta}

. It is most likely a lock-in phase. The structure, which was solved using seeding of the modulation from thos ...

The versatile chemistry and non-centrosymmetric crystal structures of salt-inclusion vanadate hybrids

Wendy Lee Queen

Three unique structure types of the vanadate-based mixed-metal oxide systems (salt)·MnII-Vv-O and (salt)·CuII-Vv-O are presented, with a focus on the role of the asym. vanadate units. Lattice parameters were obtained for (CsCl)2Mn(VO3)2, (CsBr)2Mn(VO3)2, ( ...

Compositional variations at ultra-structure length scales in coral skeleton

Anders Meibom, Karin Lederballe Meibom

Distributions of Mg and Sr in the skeletons of a deep-sea coral (Caryophyllia ambrosia) and a shallow-water, reef-building coral (Pavona clavus) have been obtained with a spatial resolution of 150 nm, using the NanoSIMS ion microprobe at the Museum Nationa ...

Coupled Biogeochemical processes governing the stability of bacteriogenic UO2+x

Elena Suvorova Buffat, Harish Veeramani, Jonathan Sharp

The chemical stability of bacteriogenic “UO2” is one of the seminal issues governing its success as an in-situ waste form in remediated subsurface locations. Little detail is known about the structure and reactivity of this material, but based on compariso ...

Electronic excitations induced by the impact of coinage metal ions and clusters on a rare gas matrix: neutralization and luminescence

Wolfgang Harbich, Christoph Sieber

Low energy collisions of atomic ions and cluster ions with rare gas covered metal substrates can lead to strong light emission which is element and size specific. Instead of a direct energy transfer into the electronic system of the cluster the observed em ...
