A novel coordination complex formed by dinuclear metal complexation is provided. The complex is a dinuclear metal complex of a compound, wherein the compound comprises a conjugation ring system substituted with: a) an electron donating group selected from —OH, —SH and —NH₂; b) an indicating group selected from a chromogenic group, a fluorescent group and an electrochemical group; and c) two binding auxiliary groups, in combination with the electron donating group each of which being coordinated with the metal to provide an anion bonding site, wherein as the complex binds to a anion, the coordination of the electron donating group with the metal is weakened and electron donation of the electron donating group to the conjugation ring system is reinforced such that the reinforced electron donation by the electron donating group is transferred through the conjugation ring system to the indicating group to produce an indicating signal concomitant with the change of its electronic density. The coordination complex shows high sensitivity and high selectivity for pyrophosphate over other anions in an aqueous solvent over a wide pH range. Therefore, the complex is useful for pyrophosphate assay as a pyrophosphate sensor.

Fused ring bridge, ring locked dyes that form thermally stable photorfractive compositions. The fused ring bridge structures are pi -conjugated bonds in benzene-, naphthalene- or anthracene-derived fused ring systems that connect donor and acceptor groups. The donor and acceptor groups contribute to a high molecular dipole moment and linear polarizability anisotropy. The polarization characteristics of the dye molecules are stabilized since the bonds in the fused ring bridge are not susceptible to rotation, reducing the opportunity for photoisomerization. The dyes are compatible with polymeric compositions, including thermoplastics. The dyes are electrically neutral but have charge transport, electronic and orientational properties such that upon illumination of a composition containing the dye, the dye facilitates refractive index modulation and a photorefractive effect that can be utilized advantageously in numerous applications such as in optical quality devices and biological imaging.

A cellular electron cooled storage ring system and method for achieving particle-fusion based energy, including a vacuum chamber to allow electron beam and ion beam merging and separation, cathodes to generate the electron beams, collectors to collect the electron beams, and magnetic field generation devices to guide the electrons and ions on their desired trajectories as well as contain neutralizing particles. By overlapping the electron and ion beams, thermal energy is transferred from the ion beams to the electron beams, which allows the invention to overcome particle losses due to resonances, scattering and heating of the ion beams. Advantageously, ions are accelerated to an energy that is near optimum for fusion reactions to occur, and uses electron energies that maintain this advantageous situation. Advantageously, the recirculation of ions that do not fuse or scatter at too large of an angle is allowed, giving such ions additional chances to participate in a desired fusion reaction. Advantageously, the invention allows for a continual addition of new ions to be added to the circulating ions already in the system. This combination of advantages results in a significant improvement in the predicted output power to input power ratio over previous particle fusion technologies. The invention will also enable improved yields of fast neutrons for materials testing.
