摘要： A method of forming a titania-coated inorganic particle comprising the steps of: (a) agitating a mixture of inorganic particle and organic solvent; (b) adding titania precursor dropwise into the mixture of step (a) under agitation; and (c) adding catalyst to the mixture of step (b) thereby converting said titania precursor to titania which then forms a coating on said inorganic particle; wherein steps (a) to (c) are performed at neutral pH and ambient temperature.

摘要： The disclosed retroreflective element includes a polymeric core that is loaded with a plurality of first beads and second beads distributed at the perimeter of the core. The first beads are different than the second beads. Because of the beads in the core, the retroreflective element remains useful for returning light even after portions of the core begins to wear away. Further, when the retroreflective elements get wet, water will settle to the bottom of the perimeter of the core. Therefore, using the second beads with a refractive index suited for wet conditions, while the first beads have a refractive index suited for dry conditions allows the retroreflective element to be useful in both wet and dry conditions even while the retroreflective element wears during use.

摘要： The present disclosure generally relates to retroreflective elements including a core and a plurality of glass or glass-ceramic beads adjacent to the core. The retroreflective elements further include a plurality of particles having a diameter that is less than the diameter of the glass or glass ceramic beads in the retroreflective elements. The present disclosure also generally relates to articles (including, for example, retroreflective roadway liquid pavement markings) including these retroreflective elements and methods of making and using these retroreflective elements.

摘要： A glass shard-paved structure includes a substrate having an outer surface, and a plurality of glass shards bonded to the outer surface of the substrate so as to form a glass pattern on the substrate. The glass shards are formed by mixing raw glass shards with carbon powders so as to permit adhesion of the carbon powders to the surface of each of the raw glass shards, heating the raw glass shards so as to melt the surface of each of the raw glass shards, cooling the heated glass shards, and removing the carbon powders from the glass shards.
