Abstract: Disclosed is an agrochemical delivery unit comprising an impermeable cell which is a cell made of material that is impermeable to water; an agrochemical within the impermeable cell; and a wick comprising a hydrogel, said wick having a portion located within the impermeable cell and a portion located outside of the impermeable cell. Also disclosed is an agrochemical delivery unit comprising (a) a cell comprising two or more cell wall segments wherein at least one segment is impermeable to water and at least one segment is permeable to water; and (ii) an agrochemical within the cell.

Abstract: There is disclosed a catalytic substrate surface where in the substrate surface comprises particles in the size range 2-500 nm, said particles comprising TiO2, wherein at least 50 wt % of the Ti in the particles is leachable in 37% HCl. A method for its manufacture is also provided. One advantage is that the higher fractions of Ti leachable in 37% HCl give a better coating with better adhesion, in particular on objects comprising protonatable acidic oxides, such as SiO2. The higher fraction of Ti leachable in 37% HCl gives better transparency and dispersion stability. The resulting surface exhibits both improved activity and improved adhesion of the particles. There is no color change and/or speckles on the substrate, allowing anti-pollution surfaces to be produced also on decorative surfaces. The TiO2-comprising layer is thin and easily applied in the production line.

Abstract: Disclosed are a new composite material and a process for synthesizing highly charged, highly monodisperse, core-shell particles with high refractive index cores, as well as stable, long lasting crystalline colloidal arrays (CCAs) formed thereof. A preferred embodiment of the core particle can be highly monodisperse zinc sulfide (ZnS) particles and a preferred embodiment of the shell can be highly charged polyelectrolytes. The CCAs formed thereof are charge stabilized photonic crystals that shows distinctive first and second order Bragg diffraction peaks whose locations vary over a wide spectral region from UV through visible to IR, with unusually strong intensity and broad band width due to the high index of refraction. These high refractive index particles are useful in applications such as optical filters, optical coatings, cosmetics and photonic crystals sensors and devices.

Abstract: One aspect of the present disclosure is directed towards a new film forming paint that Bragg diffracts light in the visible and NIR spectral regions. The paint may be comprised of highly charged polymer spheres that self assemble and maintain their diffraction in the presence of the different ingredients of the paint formulation, so that the self assembled arrays diffract light in both wet and dry states. Another aspect of the present invention is directed to a process for making highly charged polymeric spheres. Another aspect of the present invention is directed to the highly charged polymeric spheres themselves. The high surface charge density of the spheres enables the stability and self assembly of the spheres in the presence of the other paint ingredients. These spheres can find useful practical applications in paints, inks, coatings, cosmetics and light filtering applications. Because of the rules governing abstracts, this abstract should not be used to construe the claims.
