Archimedean Synthesis and Magic Numbers: “Sizing” Giant Molybdenum‐Oxide‐Based Molecular Sphe

Pythagorean harmony can be found in the spherical polyoxometalate clusters described here (see illustration for an example of a structure), since there are interesting relationships between the so‐called magic numbers (12, 32, 42, 72, 132) relevant for spherical viruses and the number of the building blocks in the cl...

Diels−Alder Chemistry of Graphite and Graphene: Graphene as Diene and Dienophile

The zero-band-gap electronic structure of graphene enables it to function as either the diene or the dienophile in the DielsAlder reaction, and this versatile synthetic method offers a powerful strategy for the reversible modification of the electronic properties of graphene under very mild conditions. ...

Observation of Higgs Boson Decay to Bottom Quarks

The observation of the standard model (SM) Higgs boson decay to a pair of bottom quarks is presented. The main contribution to this result is from processes in which Higgs bosons are produced in association with a W or Z boson ( V H ), and are searched for in final states including 0, 1, or 2 charged leptons and two id...

Modeling for the Active Site of Sulfite Oxidase: Synthesis, Characterization, and Reactivity of [MoVI

The enzyme, hepatic sulfite oxidase, is responsible for the physiologically important oxidation of sulfite to sulfate. 1 This enzyme is dimeric with each monomer containing a single Mo cofactor and a cyt 65-type heme. 2 The conversion of sulfite or bisulfite to sulfate, a two-electron process, is presumed to occur at a...

Effect of Covalent Chemistry on the Electronic Structure and Properties of Carbon Nanotubes and Graph

In this Account, we discuss the chemistry of graphitic materials with particular reference to three reactions studied by our research group: (1) aryl radical addition, from diazonium precursors, (2) DielsAlder pericyclic reactions, and (3) organometallic complexation with transition metals. We provide a unified treatme...
