A fiber-reinforced building material in one embodiment incorporates cellulose fibers that are chemically treated with a dispersant to impart improved dispersibility to the fibers. The fibers are treated with a dispersant which deactivates the hydroxyl sites of the fiber surfaces and in some cases, making the fiber surface more hydrophobic. The dispersant inhibits the hydroxyl groups on the cellulose fiber surface from bonding with hydroxyl groups of other fibers and from bonding with hydroxyl groups of the same fiber, thereby significantly reducing inter-fiber and intra-fiber hydrogen bonding. The treated fibers can be readily dispersed and uniformly distributed throughout a mixture without re-clustering or reclumping once the mechanical mixing action stops. The chemically treated fibers with improved dispersibility improve the fiber distribution and reinforcing efficiency, which in turn improves key physical and mechanical properties of the material such as the modulus of rupture, z-direction tensile strength, and toughness, and surface finishes. With improved fiber reinforcing efficiency, less dosage of fiber is needed to achieve the required physical and mechanical properties.

The transmission media may be a multi-core fiber (MCF), a multi-mode fiber (MMF), a few-mode fiber (FMF), or a ribbon cable comprising nominally uncoupled single-mode fiber (SMF).

A light guide and various vehicular lamp assemblies using the same are presented herein. In one embodiment, the lamp assembly includes a light source, such as an LED module. A light coupler is operable to receive light from the light source, and distribute the light in a first direction. The light guide includes an elongated, curvilinear body with first and second longitudinal end faces, and opposing light-emitting and light-guiding surfaces extending between the two end faces on a respective side of the body. The first end face communicates with the light coupler to receive light therefrom. The light guide body transmits light generated by the light source along the longitudinal expanse thereof. The light-guiding surface includes an array of longitudinally-spaced optical grooves configured to refract light generated by the light source in a second direction.

A lighting system includes multiple lighting elements, a light guide, and a first selective wavelength reflective element for mixing light outside of the light guide. The lighting elements include a first lighting element having a first wavelength. The light guide receives light from the lighting elements. The first selective wavelength reflective element is positioned between the first lighting element and the light guide to partially transmit light of the first wavelength to the light guide, and to partially reflect light of the first wavelength. Partially reflecting light away from the light guide allows a fraction of the light to be mixed with another color of light prior to entering the light guide. By mixing multiple colors of light outside of the light guide in this manner, discoloration of the LCD panel may be limited or eliminated. Additionally, oversizing the diffusion panel may be limited or eliminated.

An object according to the present invention is to provide a catalyst layer for a fuel cell, which prevents the lowering of the performance due to the lack of oxygen in a high current density region and can provide a desired power, even when containing a small amount of catalyst particles. The catalyst layer for a fuel cell has a structure including: an electroconductive carrier made of a secondary particle which is formed by agglomerating a plurality of primary particles; catalyst particles which are dispersed on and carried by the electroconductive carrier; and an ionomer which covers the electroconductive carrier and the catalyst particles, wherein the catalyst particles have the particle quantity in a range of 0.05 mg / cm2 to 0.15 mg / cm2, the electroconductive carriers have the average secondary particle size in a range of 100 nm to 180 nm, and the ionomer has the film thickness in a range of 6 nm to 16 nm. Thereby, the catalyst layer for a fuel cell can reduce the amount of oxygen per one piece of the secondary particles to inhibit oxygen from concentrating on the surface of the ionomer, and shortens the diffusion distance of oxygen in the ionomer to alleviate a rate-controlled condition by the concentration diffusion process of oxygen in the catalyst layer.
