A building element selected from a roofing tile or siding element may be formed from a first cementitious mixture and a second cementitious mixture containing a photocatalytic cementitious mixture. The first cementitious mixture and the photocatalytic cementitious mixture may be co-formed into a shaped uncured two layer monolith having a base layer of the first cementitious mixture and a top layer of the photocatalytic cementitious mixture. The shaped uncured two layer monolith is then cured. The resulting building element may be algae-resistant.

A pipe system includes first and second pipes having first and second ends welded together forming a girth-weld and a corrosion coating covering the girth-weld. In addition, a flexible sheet is provided to cover the girth-weld. The flexible sheet comprises a first structured layer that mechanically couples to the corrosion coating, where the corrosion coating permeates a substantial portion of the first structured layer. The flexible sheet also includes a second layer comprising a polymer layer adhered to the first layer, the second layer protecting the corrosion coating from mechanical or environmental damage. Alternatively, the protective cover comprises a polymer material and includes a port formed therethrough adapted to receive a delivery mechanism that delivers a corrosion coating to the girth-weld.

The ink receptor media of the invention comprise an ink receptor comprising surfactant templated mesoporous particles dispersed within an organic binder on the substrate. The ink receptor media may also have an ink fixing material within or on the ink receptor. The invention also describes surfactant templated silica particles having a narrow particle size distribution and having intraparticle pore sizes of about 1.5 to about 10 nm and methods of preparing said particles. The invention also describes a colloidal dispersion of STM particles methods of making said dispersions.

A method for tracking procedures performed on an article of PPE includes the steps of providing an article of PPE configured with a first smart tag to a first individual prior to performance of a first task; processing the article of PPE in a first cycle after the first individual performs the first task; and retrieving first information from the first smart tag during at least one of: before, during and after processing the article of PPE in the first cycle. The method further includes the steps of providing the article of PPE configured with a second smart tag to a second individual prior to performance of a second task; processing the article of PPE in a second cycle after the second individual performs the second task; and retrieving second information from the second smart tag during at least one of: before, during and after processing the article of PPE in the second cycle.
