Abstract:
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.
Abstract:
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.

Abstract:
This invention comprises a method to form a family of supported films film with pore size in the approximate range 0.8-20 nm exhibiting highly ordered microstructures and porosity derived from an ordered micellar or liquid-crystalline organic-inorganic precursor structure that forms during film deposition. Optically transparent, 100-500-nm thick films exhibiting a unique range of microstructures and uni-modal pore sizes are formed in seconds in a continuous coating operation. Applications of these films include sensors, membranes, low dielectric constant interlayers, anti-reflective coatings, and optical hosts.
