An unprecedented polynuclear metal cluster-pillared triangular prism was built by a macrocycle-directing strategy. Discrete architectures of three silver cluster-involved metallosupramolecules were characterized by single crystal X-ray crystallography and spectroscopy studies.

A new synthetic method for polynuclear lanthanoid complexes that are embedded in molecular polyoxotungstates has afforded the highest nuclearity polyoxometalate-encapsulated Gd complex and the first decanuclear Yb complex of any sort to be structurally characterized.

A novel decanuclear Co(II) cluster, [Co(10)(Q)(12)(μ(6)-CO(3))(4)]·2.5DMF (1) (Q = 8-hydroxyquinoline), has been synthesized under solvothermal conditions and characterized by powder XRD, TGA and IR spectroscopy. Single-crystal X-ray diffraction analysis shows that 1 represents a new type of decanuclear cobalt cluster with an approximate supertruncated tetrahedral shape coordinated with coexist...

Bacterioferritin isolated from Escherichia coli is of two kinds: a protein containing a polynuclear iron compound, the bacterioferritin proper and a protein free of the polynuclear iron compound, the apo-bacterioferritin. Bacterioferritin of both kinds is characterized by absorption maxima at 417,530 and 560 nm, contributed by protohaem IX. Single crystals of bacterioferritin of the space group...

We study the multitime distribution in a discrete polynuclear growth model or, equivalently, directed last-passage percolation with geometric weights. A formula for joint function is derived setting. It takes form of multiple contour integral block Fredholm determinant. The asymptotic then computed by taking appropriate KPZ-scaling limit this formula. This expected to be universal models Kardar...
