    Luminescent lanthanide coordination polymers for future photonic applications are introduced. Luminescent lanthanide polymers are composed of lanthanide ions and characteristic organic ligand units. Combination of luminescent lanthanide ions and organic ligands provides remarkable lanthanide coordination polymers with 1) triboluminescent properties from shattering of the crystals, 2) high emission quantum yields and thermo-stability for future optical devices, and 3) thermo-sensing properties for aerospace developments. Luminescent lanthanide coordination polymers are expected to open up a new field of photo-science and technology.

    Recently, we have carried out research on amphiphilic dendrimers containing several alkyl chains and a dendrimer skeleton with the aim of achieving high performance and versatile functionality. This review describes the design and synthesis, properties such as critical micelle concentration and surface tension, and properties of micelles formed in aqueous solution by star-type cationic amphiphilic dendrimers comprised of several quaternary ammonium salt-type cationic surfactant molecules connected to poly(amidoamine)dendrimer, tadpole-type cationic amphiphilic dendrimers comprised of a cationic surfactant and dendrimer, and tadpole-type amphiphilic dendrimer with an alkyl chain and dendrimer.

    After the development of molding technology and many kinds of reinforced materials that make up plastic -based composite materials (FRP), many plastic materials have been put to practical use as light-weight structural materials. So it is no exaggeration to say that the expansion of applications of FRP structures with excellent corrosion resistance and light-weight properties has largely been brought about by advances in adhesives and bonding technology of plastic-based materials.
    Due to big changes in light-weight structures with the development of FRP, various bonding methods and systems for complicated shapes have been developed for many types of adhesives. Mechanical joining, such as point riveting by rivets or bolts, is universal for the joining of steel materials. However, adhesive joints which bond FRP surfaces can provide excellent stress relaxation and an even distribution of the joint stress of bonded parts.
    The present article reviews the current status and trends in adhesive bonding techniques which have changed with the development of FRP and the differences between steel and plastic-based structural bonding systems.
