In a departure from the conventional design of hydrophobic microporous layers (MPLs), the author conceived the idea of hydrophilic double MPLs. The hydrophilic layers are composed of carbon fibers and a hydrophilic polymer. The ratio of hydrophilic polymer to carbon fiber is designed to be low in the first layer (catalyst side) and high in the second layer (gas diffusion media, or GDM, side) in order that the two layers should function differently. The first layer removes liquid water from the cathode catalyst layer and the second layer retains water, thus preventing the membrane from drying-out. The membrane-electrode assembly (MEA), which uses a cathode GDM with hydrophilic double MPLs, exhibits excellent performance under both high and low humidity conditions. It was also shown that even the hydrophobic treatment of the cathode GDM substrate is not so critical when the hydrophilic double MPLs are employed. This work clearly indicates that costly hydrophobic GDM substrates and MPLs are not always necessary in the design of MEAs. © 2010 The Electrochemical Society. Source

Glasses of the Bi 2O 3-TeO 2-B 2O 3 ternary system were developed and their linear and nonlinear optical properties were investigated. The absorption edges of these glasses were found to be 367-384 nm with a good transmittance in visible wavelength, although they exhibit the refractive indices as high as 1.98-2.12 at 633 nm. The absorption edges are quite steep and they are analyzed by the Urbach theory. The obtained Urbach energies of these glasses are 73-79 meV which are comparable to silica glasses. The high refractive index and its glass composition dependency are discussed according to the basics of the electronic polarizability and optical basicity. The high third order nonlinear susceptibility χ (3) = 2.0 × 10 - 12 esu at 800 nm was also obtained in the 36Bi 2O 3-18TeO 2-46B 2O 3 glass. © 2011 Elsevier B.V. All rights reserved. Source


The present invention relates to a method for producing a float glass sheet, containing a step of melting a glass source material, a step of forming the glass melted in the previous step into a glass ribbon while allowing it to float on a molten metal, and a step of annealing the glass ribbon, in which the float glass sheet is a soda lime silicate glass, and in the forming step, a top surface of the glass ribbon that is opposite to a bottom surface thereof to be in contact with the molten metal is subjected to a dealkalization treatment in the float bath for 1 to 30 seconds and a surface temperature of the glass ribbon during the dealkalization treatment is 600 C. or higher.

An antenna device includes an antenna conductor on windshield glass, a feeding point having adjacent first and second feeding parts on the antenna conductor, and an auxiliary conductor including electrically connected horizontal and vertical conductors. The antenna conductor is adjacent to a connecting part between the horizontal and vertical conductors, and has a semi-loop shape with a cutout part in a loop-shape. The feeding point is located along the horizontal conductor, and the cutout part is located opposite from the horizontal conductor with respect to a horizontal line passing through a center point of a region surrounded by a semi-loop element, and opposite from the vertical conductor with respect to a vertical line passing through the center point. A length of a first element forming a part of the antenna conductor is 0.2
