Abstract: A reflective material comprising a multilayered array of particles encapsulated by a matrix material, the reflective material defining a primary surface, the reflective material exhibiting: (i) visible retroreflection of incident radiation, wherein a wavelength of visible retroreflected radiation decreases from a first visible wavelength at a first angle to the primary surface to a second, shorter wavelength of visible retroreflected radiation as the viewing angle to the primary surface increases; and (ii) Bragg diffraction of the incident radiation, wherein the wavelength of radiation Bragg diffracted normal to the primary surface is longer than the wavelength of visible radiation, such that no visible radiation is retroreflected or Bragg diffracted in a direction normal to the primary surface.

Abstract: Hard coating compositions are disclosed containing graphenic carbon particles. The coating compositions include polymeric resins such as polyurethane or polyester with relatively small amounts of graphenic carbon particles that provide increased hardness.

Abstract: A method for stabilizing metal ions in recirculating water systems is disclosed. This method utilizes an admixture comprising a) an ethylenically unsaturated water-soluble polymer and/or a water soluble phosphonate, b) methylene bis(thiocyanate), and c) 2-(thiocyanomethylthio)benzothiazole to solubilize metal ions thereby reducing deposition and corrosion.

Abstract: Multifunctional scale inhibitor compositions, alone or together with polymeric structures, are described which are characterized by having, in addition to a phosphonomethylamino group, a sulfonic acid and/or carboxylic acid group. By incorporating several types of functional groups into a single molecule, control of scale formation and deposition under more severe conditions than normally encountered can be attained.
