  • Patent number: 9228263
    Abstract: A chromate-free, self-healing conversion coating solution for magnesium alloy substrates, composed of 10-20 wt. % Mg(NO3)2.6H2O, 1-5 wt. % Al(NO3)3.9H2O, and less than 1 wt. % of [V10O28]6? or VO3? dissolved in water. The corrosion resistance offered by the resulting coating is in several hundreds of hours in salt-spray testing. This prolonged corrosion protection is attributed to the creation of a unique structure and morphology of the conversion coating that serves as a barrier coating with self-healing properties. Hydroxoaluminates form the backbone of the barrier protection offered while the magnesium hydroxide domains facilitate the “slow release” of vanadium compounds as self-healing moieties to defect sites, thus providing active corrosion protection.

  • Patent number: 8987352
    Abstract: Phase separated self-healing polymer coatings having a “biphasic” thermoset/thermoplastic morphology to achieve self-healing. The biphasic structure has: (i) a major “load-bearing” thermoset phase that has superior strength and performs major mechanical and structural functions, and (ii) a “self-healing” phase of a thermoplastic healing agent to repair the material and restore its mechanical and structural integrity after being damaged. The phase-separated morphology is achieved through phase separation via a reaction process.

  • Patent number: 8481455
    Abstract: Surface functionalized sorbent particles for vapor-phase mercury removal, especially in the presence of SO3 in, for example, flue gas. The sorbent surface is modified to increase the SO3 resistance of vapor-phase mercury sorbents. The mercury removal efficiency is immune to the presence of SO3, which is not the case with conventional activated carbon as well as brominated activated carbons. The sorbent is based on carbon particles with a metal oxide coating on the surface. The thin metal oxide layer acts as an amenable surface to introduce functional groups. The metal oxide coated carbon was further modified with amine molecules, to increase its resistance towards SO3 poisoning.

  • Patent number: 8303823
    Abstract: Nanoscale additives and methodology for their use during polymer-aided sludge dewatering to increase the dewatering efficiency compared to traditionally used polymer-only dewatering processes. The nanoscale additive increases the percent solids in the dewatered cake compared to polymer-only treatment. When the nanoscale additives are added, the centrifugal force (shear) required to obtain high percent solids can be significantly reduced and the optimum polymer dose required for effective dewatering is also significantly reduced.

  • Patent number: 8263524
    Abstract: A new class of carbon-based sorbents for vapor-phase mercury removal is disclosed in this invention. The optimum structure of the sorbent particles, and a method to produce the sorbent, are described. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The thin metal-oxide layer acts as a barrier for the adsorption of Air Entrainment Admixture (AEA), the component used to stabilize bubbles in cement), thereby enhancing its concrete friendliness. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.

  • Patent number: 8263525
    Abstract: A new class of sorbents for the removal of mercury from contaminated water. The optimum structure of the sorbent particles and a method to produce the same is described. The newly developed carbon-based particles are differentiated from other sorbent particles by their high accessible surface area and high affinity towards mercury ions that leads to faster and higher mercury adsorption. The sorbent is based on carbon particles with a metal-oxide coating on the surface. The metal-oxide is coated on the surface of carbon, using a solution-based method. The metal-oxide coated carbon was further modified with sulfur molecules, to increase its mercury removal capacity.

  • Patent number: 6723387
    Abstract: A thermal spray method for the fabrication of ceramic/metal and ceramic/ceramic hardcoating for wear applications. The method makes use of feedstock powder, composed of micron-scale aggregates of hard phase material particles that are either mixed or coated with a readily fusible nano-scale binder phase material. Thus, during thermal spraying, the nanostructured material undergoes rapid melting while the aggregated material is heated but not necessarily melted. A dense coating is formed when the molten nano-material fills the available pore spaces between the heated and softened aggregates, providing a strong and tough matrix for the consolidated material. Optimal wear properties are achieved when the volume fraction of aggregated particles is high, typically in the range of 0.5-0.9. Aggregated material may be composed of one, two or more particles of difference sizes and/or compositions, with particle size distribution that gives high packing density for the hard phase.
