＊＊＊START＊＊＊[0001] Carbon nanotubes (also referred to as carbon fibrils) are seamless tubes
of graphite sheets with full fullerene caps which were first discovered as
multi-layer concentric tubes or multi-walled carbon nanotubes and subsequently
as single-walled carbon nanotubes in the presence of transition metal catalysts.
Carbon nanotubes have shown promising applications including nanoscale electronicdevices, high strength materials, electron field emission, tips for scanningprobe microscopy, and gas storage.

[0002] Generally, single-walled carbon nanotubes are preferred to multi-walledcarbon nanotubes for use in these applications because they have fewer defects
and are therefore stronger and more conductive than multi-walled carbon
nanotubes of similar diameter. Defects are less likely to occur in single-walledcarbon nanotubes than in multi-walled carbon nanotubes because multi-walledcarbon nanotubes can survive occasional defects by forming bridges between
unsaturated carbon valences, while single-walled carbon nanotubes have noneighboring walls to compensate for defects.

課題図表として表示されるformula Iを参考にしてください。
RCMはRing Closing Metathesisの略です。

＊＊＊START＊＊＊[0011] The RCM methodology disclosed to date suffers from modest yields and low
catalyst selectivity. This translates into low efficiency and higher costs. The
object of the present invention therefore is to find superior metathesis
catalysts and an improved process that is applicable on technical scale and isable to overcome the disadvantages exhibited by catalysts known in the art. The
compounds of formula I can advantageously be used in metathesis reactions,particularly in ring closing metathesis or cross metathesis reactions.

[0012] Ru-complexes of formula I wherein R1, R2, R3', R3'', X1, X2, Y1, L, a, b,c and d, are as defined herein above and the dotted line is an optional bond,have been found to be very useful catalysts in metathesis reactions such as inring closing metathesis and in cross metathesis reactions. If the optional bondis absent (i.e. the amide carbonyl group does not coordinate to the ruthenium)
the complex is a pentacoordinated ruthenium complex and if the optional bond ispresent, (i.e. the amide carbonyl group coordinates to the ruthenium) the complex
is a hexacoordinated ruthenium complex.

＊＊＊START＊＊＊[0031] Fabrication and Photovoltaic Performance of Cells with a TiO2 FilmCografted with K19 Dye and 1-decylphosphonic Acid Coadsorbate
A screen-printed double layer of TiO2 particles was used as photoanode. A 10
micrometer thick film of 20 nm sized TiO2 particles was first printed on thefluorine-doped SnO2 conducting glass electrode and further coated by 4 micrometer
thick second layer of 400 nm sized light scattering anatase particles.
Fabrication procedure for the nanocrystalline TiO2 photoanodes and the assembly
as well as photoelectrochemical characterization of complete, hot-melt sealed
cells has been described above. The electrolyte used for device E contained
0.6 M 1,2-dimethyl-3-propylimidazolium iodide (DMPII), 0.1 mM M I2, and 0.5 M N-methylbenzimidazole in 3-methoxypropionitrile. The TiO2 electrodes wereimmersed at room temperature for 12 h into a solution containing 300 micromolar
K19 dye and 75 micromolar 1-decylphosphonic acid coadsorbate in the mixture ofacetonitrile and tert-butanol (volume ratio: 1:1).
