as a Model with Less Number of Reducing Ends
The reducing end-groups in cellulose were found to be converted to the non-reducing glycosides through heat treatment with various alcohols such as glycerol, glucitol and even methanol vapor at 180-240 C. This reaction proceeded without addition of any catalysts. Formation of the glycosidic bonds between cellulose reducing ends and alcohols was confirmed with the successive extraction with water, an alcohol with UV-absorption and measurement of reducing end-groups. A cellulose-mannitol mixture...

Experimental
The electrolyte solution was comprised of TMHATFSA and SiCl4. Silicon tetrachloride Wako Pure Chemical Industries, Ltd., purity gt 99 was dissolved into TMHATFSA as received from Stella Chemifa Corporation. The water content of the electrolyte solution supplied to the electrolysis was verified to be below 10 ppm by Karl-Fischer titration Hiranuma Sangyo Co., Ltd., Aquacounter AQ-200 . The electrolyte solutions containing different concentrations of SiCl4 were supplied to a Fourier transform...

Ferric Oxide Carbon Composite Synthesized by Aqueous Solution Method as a
Abstract Iron oxide is one of the most promising materials as an electrode of lithium-ion batteries due to its low toxicity and low cost. In this study, composites of nano-sized g-ferric oxide y-Fe2O3 and carbon material is synthesized by aqueous solution method, which is generally conducted at low cost. Acetylene black AB or ketjen black KB is adopted for the carbon component in the composite. These composites y-Fe2O3 AB and y-Fe2O3 KB are examined as cathodes of lithium-ion batteries and they...
In situ Raman Spectroscopy
Next, in situ Raman spectroscopy was performed to investigate the transition of bonding states around Si atoms. Figure 2 shows Raman spectra in situ recorded at the interface between the electrolyte solution and a Ni substrate during the electrolysis at -2.0 V vs. Pt QRE in TMHATFSA containing 0.1 mol L-1 SiCl4. In order to facilitate the comparison of each spectrum, the background spectrum, which was measured before the electrolysis, has been subtracted from all the spectra measured during the...
Renaissance of Nuclear Energy in the USA Opportunities Challenges and Future
Abstract The future of nuclear energy is an important issue for many countries intending to reduce their dependence on fossil fuels and achieve the reduction targets for green house gas GHG emissions. As of June, 2008, there were 439 operating nuclear reactors with a total generating capacity of 372 GWe and 42 power reactors under construction in 15 countries. In the USA, a total of 104 nuclear reactors currently produce 20 of the electricity and account for at least 70 of all GHG-free...

Reconstitution of Photosynthetic Membrane Proteins into Liposomes
Figure 1 shows the absorption spectra of LH2 A and LH1-RC B in a Tris buffer solution 20 mM pH 8.0, 0.1w LDAO dashed line and in a reconstituted lipo-somal membrane dotted line . The characteristic absorption bands attributed to Qy of bacteriochlorophyll a in these proteins are essentially identical in both conditions. The LH2 complexes reconstituted into the lipid bilayer can be successfully visualized with high resolution AFM. When the liposomal solution containing reconstituted LH2 was...
Introduction Hrm
Propagation of solar power generation is indispensable to establish the CO2 zero-emission energy system throughout the world. Silicon is the most favorable material for photovoltaic cells due to its abundance in the earth's crust. It is anticipated that the demands for silicon and its thin films will continuously increase in the future. In order to meet such great demands, we have to seek for low-cost processing Y. Nishimura , T. Nohira, and R. Hagiwara Department of Fundamental Energy Science,...
Photocurrent Measurement
Photocurrents were measured at -0.2 V vs. Ag AgCl in a home-made cell 100 cm3 that contained three electrodes an ITO electrode incorporating the PE-Cn-ZnPChlide a in lipid bilayers as the working electrode an Ag AgCl saturated KCl as the reference electrode and a platinum flake as the counter electrode. The working electrode was illuminated using a xenon lamp unit SM-25, Bunkokeiki, Japan where the light was pared through a monochromator. An aqueous solution consisting of 0.1 M phosphate buffer...

Results and Discussion
RNP receptors for dopamine were isolated from an RNP library by in vitro selection method as previously reported 3, 5 . In each round of selection, an RNP pool was incubated with a dopamine-immobilized agarose resin. After removal of unbound RNP fraction, a bound RNP fraction were recovered by specific elution with free dopamine. An ethanolamine-agarose resin was utilized in the negative selection step of dopamine, respectively. The bound RNA fractions were collected, reverse transcribed and...
Raman Spectroscopy of SiClTMHATFSA Electrolytes
First of all, the dissolved state of silicon chloride species in TMHATFSA was investigated by Raman spectroscopy. Figure 1 summarizes the results of peak separation for the vx symmetric stretch mode of SiCl4. It exhibits almost no influence of TMHATFSA on the peak position and width for the vx mode of SiCl4 in the electrolyte solutions. It means that silicon chloride species exists mainly as SiCl4 molecules in TMHATFSA without making bonds with other molecules to form complexes, polymers, or...

Thermal neutron flux distribution was estimated through the horizontal measurement of n5In n,y U6mIn reaction rates by the activation analysis of an indium wire of 1.0 mm diameter. The wire was set in an aluminum guide tube, from the tungsten target to the center of the fuel region 13, 14-A, P in Fig. 1 , at the height of the center of the fuel assembly. In these static experiments, the subcritical system was made by the full insertion of C1, C2 and C3 rods as the same as the kinetic...

thermally averaged terms as lt lt cos29 gt gt , once the rotational wave packet is formed at At 0 with the pump pulse. The evaluation of Trot in the experiment can accurately be made by comparing the frequency spectrum of the observed time-dependent harmonic signal with the theoretical, because the spectrum is very sensitive to the distribution of rotational states at the unique fitting parameter Trot, as shown below. Figure 1 shows a typical examples of the time-dependent harmonic signal...
