Seventeen‐Coordinate Actinide Helium Complexes [PDF]

open access: yesAngewandte Chemie, 2017
AbstractThe geometries and electronic structures of molecular ions featuring He atoms complexed to actinide cations are explored computationally using density functional and coupled cluster theories. A new record coordination number is established, as AcHe173+, ThHe174+, and PaHe174+are all found to be true geometric minima, with the He atoms clearly ...

MicroRNAs coordinately regulate protein complexes [PDF]

open access: yesBMC Systems Biology, 2011
Abstract Background In animals, microRNAs (miRNAs) regulate the protein synthesis of their target messenger RNAs (mRNAs) by either translational repression or deadenylation. miRNAs are frequently found to be co-expressed in different tissues and cell types, while some form polycistronic clusters on genomes ...
