  • Patent number: 7595061
    Abstract: A method for controlling the growth of destructive insects and microorganisms in ground soil, includes the step of adding chitin to ground soil for inducing bacteria in the ground soil to synthesize chitinase for controlling the spread of destructive insects and microorganisms therein. The chitin may be added to the ground soil by distributing it on the upper surface of the soil or, preferably, by incorporating into the soil. In a preferred embodiment, the step of deacetylating the carbohydrate chains of the chitin for is carried out before adding to the ground soil for increasing the aqueous solubility of the chitin by producing smaller polymeric units or by increasing the availability of polar hydroxyl groups on glucosyl moieties thereof. Various bacterial cultures may also be added to the chitin prior to its distribution on, or incorporation in, the ground soil.

  • Publication number: 20090176911
    Abstract: Clays and organoclays which are treated with resorcinol diphosphate and/or bisphenol diphosphate as general nanoparticle particle dispersants and replacements for quaternary amines. The two compounds are used as self-activating and self-dispersing nanoparticles by localizing themselves on the particle surface in a polymer matrix and acting as a nanoparticle dispersants in general, as well as resulting in exfoliation of clays. The exfoliate clays may be used in polymers in lieu of other organic treatments. When these clays exfoliate poorly in a given thermoplastic, they can be added in high loading rates to polymethylmethacrylate and the PMMA-clay masterbatch added to the plastic where the organoclay performed poorly. The resulting material is a desirable nanocomposite material, with good exfoliation of the organoclay obtained in the final receiving thermoplastic.

  • Patent number: 7553898
    Abstract: A fire retardant composition that includes: a polyolefin and an additive package that includes a brominated polystyrene or decabromodiphenyl ether; a nanoclay; and metal oxide fillers in the nanometer particle range. The compositions can have high weight percentages of the additive package because of the compatibilizing effect of the nanoclay. The nanoclay is preferably a quantenary amine treated nanoclay, wherein the quantenary amine causes exfoliation of the nanoclay. The polyolefin is a polyethylene or a polypropylene and the preferred metal oxide is antimony oxide.

  • Publication number: 20080207808
    Abstract: A method of compatibilizing immiscible polymers using the mechanical deformation of quaternary amine treated organoclay particles is described. The mechanism decreases the interstitial energy resulting from immiscible polymer domain interfaces into stored mechanical energy. The polymer domains in the immiscible blend get smaller and the resulting compatibilized microcomposite/nanocomposite blend has superior mechanical properties over non compatibilized blends controls of the same materials.

  • Publication number: 20080147805
    Abstract: A centrally tracked artificial currency is provided within the context of an enterprise. This currency serves as a unit of account, medium of exchange, and store of value in a corporate “attention economy.” Users (typically coworkers) in the enterprise are allotted a base number of currency units, which they can earn, exchange, and spend in a variety of ways to signal importance and “purchase” attention of others, or priority for other organization resources. In one aspect, senders of messages can specify an amount of currency to be associated with the message, so that recipients can see the specified amount before deciding whether to read the message. Once such a system is in use, it facilitates exchange of value based on user-created transactions regarding behavior, communication, resources, incentives, and priorities.
