  text: We compare the low bias conductance of a series of alkanes terminated on their
    ends with dimethyl phosphines, methyl sulfides, and amines and find that junctions
    formed with dimethyl phosphine terminated alkanes have the highest conductance.
    We see unambiguous conductance signatures with these link groups, indicating that
    the binding is well-defined and electronically selective. This allows a detailed
    analysis of the single-molecule junction elongation properties which correlate
    well with calculations based on density functional theory.

  text: Cyclic voltammetry determines first and second oxidation potentials of conducting
    diamines. The results show that unsubstituted and methyl-substituted molecules
    conduct electricity in partially positively charged states, reflecting electron
    delocalization at the wire−gold junctions, but with electron-withdrawing substituents,
    the molecular wires are closer to uncharged as conductors, consistent with HOMO
    arguments.

  text: Conductivities have been measured for diaminoacenes with benzene, naphthalene,
    and anthracene rings. The conductivities were strong functions of the placement
    of the amino group contact points for the gold electrodes. There was good correlation
    with quantum-mechanical theory, and with the stabilities of the related mono-
    and dications of the molecules. It is proposed that some electron abstraction
    by the drain precedes electron donation by the source with these electron-rich
    systems.

  text: Mixtures of oppositely charged nanoparticles of various sizes and charge ratios
    precipitate only at the point of electroneutrality. This phenomenonspecific to
    the nanoscale and reminiscent of threshold precipitation of ionsis a consequence
    of the formation of core-and-shell nanoparticle aggregates, in which the shells
    are composed of like-charged particles and are stabilized by efficient electrostatic
    screening.
