    • The invention provides an aqueous bleaching solution for substrate treatment. The aqueous bleaching solution features a source of oxidant and a plurality of optically functional nanoparticles. The optically functional nanoparticles are nanoparticles in the range of about 0.1 nanometers to about 400 nanometers in size. The aqueous bleaching solution may optionally include one or more an oxidant-stable surfactants and optionally, one or more oxidant-stable polymers, and adjuncts. The optically functional nanoparticles are extremely stable in the aqueous bleaching solution and remain substantially suspended in the aqueous bleaching solution due to their extremely small size despite having an average density greater than that of the bleaching solution. The optically functional nanoparticles provide at least one optical functional benefit to the bleaching solution owing to their uniform and stable suspension throughout the solution, including such benefits as uniform light absorption, light and radiation scattering, fluorescent emission, phosphorescent emission, coloration, and visual aesthetic benefits and the like. Further, optically functional benefits include those benefits provided to a substrate or surface treated with the aqueous bleaching solutions whereby the optically functional property is transferred either temporarily or permanently to the substrate or surface following contact with bleaching solutions containing the optically functional nanoparticles.
    • 本发明提供了用于底物处理的水性漂白溶液。 含水漂白溶液具有氧化剂源和多个光学功能纳米颗粒。 光学功能纳米颗粒是尺寸在约0.1纳米至约400纳米范围内的纳米颗粒。 含水漂白溶液可以任选地包括一种或多种氧化剂稳定的表面活性剂和任选的一种或多种氧化剂稳定的聚合物和助剂。 光学功能性纳米粒子在水性漂白溶液中非常稳定,并且由于其极小的尺寸而保持基本上悬浮在含水漂白溶液中,尽管其平均密度大于漂白溶液的平均密度。 光学功能纳米颗粒由于其在整个溶液中均匀稳定的悬浮液而对漂白溶液提供至少一种光学功能有益效果,包括均匀的光吸收,光和辐射散射,荧光发射,磷光发射,着色和视觉美学等优点 利益等。 此外,光学功能优点包括提供给用水性漂白溶液处理的底物或表面的那些益处,由此在与含有光学功能纳米颗粒的漂白溶液接触之后光学功能性质暂时或永久地转移到基底或表面。

    • Methods, systems, and computer-readable media are provided for location-based information delivery. One system described herein includes a matching server operative to identify a geographic area in which an informational message should be transmitted to subscriber devices located within the area. The geographic area may be a statically defined fixed geographic area, such as a neighborhood, that the matching server identifies utilizing one or more fixed geographic indicators. The geographic area identified by the matching server may alternatively be an ad-hoc variably sized geographic area. The matching server may utilize one or more variable geographic indicators to identify the geographic area. Once a geographic area has been identified, the matching server is operative to transmit an informational message to subscriber devices located within the geographic area. The informational message may contain content relevant to the geographic area.
    • 提供方法,系统和计算机可读介质用于基于位置的信息传递。 本文描述的一个系统包括匹配服务器,其操作以识别其中信息消息应被发送到位于该区域内的用户设备的地理区域。 地理区域可以是静态定义的固定地理区域,例如邻域,匹配服务器使用一个或多个固定地理指标来识别。 由匹配服务器识别的地理区域可以替代地是特定可变大小的地理区域。 匹配服务器可以利用一个或多个可变地理指示符来识别地理区域。 一旦确定了地理区域,则匹配服务器可操作地向位于地理区域内的用户设备发送信息消息。 信息性消息可以包含与地理区域相关的内容。
