A three-electrode-type solar-rechargeable battery, energy-storable dye-sensitized solar cell (ES-DSSC), has been constructed by the hybridization of a typical Gratzel and conducting polymer charge-storage electrode; efficient photo-charging can be accomplished visible-light irradiation.
A novel methane-producing archaeon, designated strain HASUT, was isolated from a lotus field. Cells were Gram-negative, non-motile, irregular cocci, 2–3 μm in diameter, and occurred singly. Growth observed at 15–40 °C (optimum, 37 °C) pH 6.5–7.5 7.0). The G+C content of the genomic DNA 60.9 mol%. Strain HASUT utilized ethanol, 1-propanol, 1-butanol, hydrogen formate for growth methane production. It converted ethanol to acetate. Based on comparative 16S rRNA gene sequence analysis, shown be...
The Ag-nanoparticles (Ag-NP)/TiO2 composite thin films with various amounts of Ag (10 mol% ≤ n 80 mol%) were examined as a potential photocatalyst by decoloration reaction methylene blue (MB) in an aqueous solution. These ca. 100 nm thickness fabricated the MPM at 600 °C air. rates monitored absorption intensity MB solution indicated that amount less than 40 are not effective under vis-irradiation, though they can work UV-irradiation. Further, UV-sensitivity gradually decreased to almost...
The dissipation of MnSi layered precipitates during solidification is critical for further enhancement the thermoelectric properties higher manganese silicides. We have investigated effects partial substitution V in Mn sites and Ge Si on crystal structures these silicides detail. As previously reported, a small amount V-substitution quite effective completely dissipating striations; contrast, proportion striations always remains present Ge-substitution case, even vicinity solubility limits....
Electrochromism synchronous to the charge/discharge of a novel Li ion battery having 3 Fe 2 (PO 4 ) and Ti 5 O 12 thin-film electrodes fabricated by chemical process, molecular precursor method, was discovered.

R — O , N and firing operations produce copper red glazes resulting from the formations of Cu 2 O, metallic copper, both respectively. The symbols denote oxidizing, neutral, reducing atmospheres, respectively, in set symbols, former corresponds to heating atmosphere latter successive cooling atmosphere. All other such as fail glazes. formation mechanisms are postulated a microscopic viewpoint.
In the fields of energy exploitation, and for safety security society, portable multiple-gas sensors are essential. Although gas chromatograph (GC) is applicable to analysis, it not portable. As a result, we have proposed ball surface acoustic wave (SAW) GC using SAW sensor, which realizes high sensitivity by ultramultiple roundtrip propagation separation column fabricated micro-electro-mechanical-system technology. However, takes too long such as analyze mixed gases low molecular weights at...
Abstract Polycrystalline Cr(Si 1− x Ge ) 2 samples were prepared using arc melting and spark plasma sintering methods. Single-phase obtained for the compositional range of 0 ≤ 0.015 lattice parameters monotonically increased with .

We report herein the results of investigations into thermoelectric properties Cr(Si1−xCux)2. In Cu-content range x ≤ 0.04, single-phase Cr(Si1−xCux)2 solid solution is obtained by arc melting and spark plasma sintering. With increasing Cu content, electrical conductivity increases Seebeck coefficient decreases. Hall measurements confirm that carrier concentration mobility decreases upon substituting Si sites. substitution causes a significant decrease in lattice thermal CrSi2 enhances...
