Abstract: A fiber is prepared by melt extruding a composition including specific amounts of a polyamide and a polyphenylene ether along with a compatabilizer. Particular combinations produce fibers having a desirable combination of good tenacity and low denier per fiber. Compared to a fiber prepared from polyamide alone, the present fiber exhibits improved heat resistance and flame resistance.

Abstract: A cooling sheet for photovoltaic modules, a method of manufacturing the same, a backsheet for photovoltaic modules, a method of manufacturing the same, and a photovoltaic module are provided. The cooling sheet for photovoltaic modules which includes a resin layer can be prepared by coating or impregnating one surface of a porous substrate with a super-absorbent polymer (SAP) containing a fluid. Here, the resin layer includes the fluid-containing SAP which is formed on one surface of the porous substrate or impregnated with the porous substrate. When the cooling sheet for photovoltaic modules is attached to the outside of the weather-resistant substrate to prepare the backsheet for photovoltaic modules, it is possible to suppress an increase in power generation temperature of a photoelectric cell by evaporation of the fluid, for example water, included in the SAP, thereby improving the power generation efficiency of the photovoltaic module.

In another embodiment, the nanostructure includes a nanoparticle comprising a crystalline phase and an amorphous phase. The amorphous phase is in a selected amount. In another embodiment, the nanostructure includes crystalline titanium dioxide and amorphous titanium dioxide in contact with the crystalline titanium dioxide. Each of the crystalline and amorphous titanium dioxide has at least one dimension on a nanometer scale.

Abstract: A structure for ballistic protections is described. The structure includes at least two distinct textile elements which co-operate to stop an incident bullet along a direction, taking advantage of the dissipation of the energy associated to the bullet impact. The first textile element includes fibers capable of dissipating a part of the energy connected to the incident bullet impact owing to a crystalline phase change. The second textile element includes fibers capable of dissipating a part of energy associated to the incident bullet impact by fibrillation.

Abstract: Fabrics containing camouflage patterns are produced from dyes wherein at least certain of the colors contained in the pattern contain a low reflectance dye. The low reflectance dye is added to one or more colors in the pattern in order to preserve the camouflage pattern when viewed through night vision goggles as relatively long wavelengths, such at wavelengths greater than 900 nm. In one embodiment, the low reflectance dye comprises a thiazine. The low reflectance dye is blended with other dyes to produce colors in the pattern. By altering the concentration of the low reflectance dye in each of the colors, the colors contained in the camouflage pattern remain separate and distinct even at relatively long wavelengths.

Abstract: Methods for bonding polymeric substrates to hydroxylated surfaces such as glass are disclosed. The polymeric substrates may be elastomeric substrates such as a natural or synthetic rubber. The method may comprise applying a compound comprising at least one alkoxy silane moiety and at least one moiety selected from a nitrosoaromatic or a nitrosoaromatic precursor to one of the substrates. The nitrosoaromatic moiety may be a nitrosobenzene. The nitrosoaromatic precursor may be a nitrosobenzene precursor, such as at least one of a quinone dioxime or a quinone oxime. Novel primers and compounds suitable for use in the bonding process are also disclosed.
