  • Patent number: 10721815
    Abstract: A conductive interconnect structure comprises a polymeric substrate (e.g., a thermoplastic) and a plurality of compliant conductive microstructures (e.g., conductive carbon nanofibers) embedded in the polymeric substrate. The microstructures can be arranged linearly or in a grid pattern. In response to heating, the polymeric substrate transitions from an unshrunk state to a shrunken state to move the microstructures closer together, thereby increasing an interconnect density of the compliant conductive microstructures. Thus, the gap or pitch between adjacent microstructures is reduced in response to heat-induced shrinkage of the polymeric substrate to generate finely-pitched microstructures that are densely pitched, thereby increasing the current-carrying capacity of the microstructures.

  • Patent number: 10611687
    Abstract: A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).

  • Patent number: 10118868
    Abstract: A method of producing artificial bio-soil aggregates based on foamed concrete for plant growth that can ensure sufficient moisture and plant nutrients for the habitat of plants in non-soil conditions; obtain a lightweight, durable, and deep soil layer, and continuously provide a favorable environment for plant growth. A paste is prepared by mixing cement with an admixture, such as ochre and burnt-furnace slag; foamed concrete is formed by adding foam bubbles with an appropriate foaming rate to said paste, thereby producing soil concrete. When the foamed concrete is used, a designated compressive strength can be ensured and a number of pore spaces are formed, which allow the air to be sucked and expelled therethrough and store moisture therein. Also, hydrogel that is incorporated into the foamed concrete may supply nutrients required for plant growth, improve pest resistance, and store and supply a large amount of water.

  • Patent number: 8674004
    Abstract: A rubber composition with disperse phase particles containing poly(phenylene ether) can be formed by a method that includes melt blending an uncured rubber with a poly(phenylene ether) composition containing a poly(phenylene ether) and an oil to form an uncured rubber composition, then curing the uncured rubber composition. Before being blended with the rubber, the poly(phenylene ether) composition exhibits a glass transition temperature of about 40 to about 140° C., and during blending with the rubber, the oil component of poly(phenylene ether) composition migrates from the poly(phenylene ether) composition to the rubber, leaving a poly(phenylene ether)-containing disperse phase that gives rise to a second hysteresis peak temperature of about 160 to about 220° C. as measured by dynamic mechanical analysis of the cured rubber composition.

  • Publication number: 20140060388
    Abstract: Ultra-high-performance cementitious materials are made using suitably functionalized and relatively low-cost carbon nanofibers and graphite platelets. Polyelectrolytes and surfactants are physisorbed upon these graphite nanomaterials in water, and dispersion of nanomaterials in water is achieved by stirring. Stable and well-dispersed suspensions of nanomaterials in water are realized without using energy-intensive and costly methods, and also without the use of materials which could hinder the hydration and strength development of ultra-high-performance cementitious materials. The water incorporating dispersed nanomaterials is then mixed with the cementitious matrix and, optionally, microfibers, and cured following standard concrete mixing and curing practices. The resulting cementitious materials incorporating graphite nanomaterials and optionally microfibers offer a desired balance of strength, toughness, abrasion resistance, moisture barrier attributes, durability and fire resistance.

  • Publication number: 20130316163
    Abstract: A gypsum board comprises a cover sheet and a gypsum layer disposed on the cover sheet. The gypsum layer comprises the reaction product of an isocyanate, water, and stucco. The isocyanate increases the moisture resistance of the gypsum board. A method of manufacturing the gypsum board comprises the steps of combining the isocyanate, the water, and the stucco to form a slurry, and applying the slurry to a cover sheet to form the gypsum layer on the cover sheet.

  • Patent number: 8541518
    Abstract: A process for the preparation of a copolymer in a semicontinuous mode of operation in a polymerization apparatus containing a polymerization reactor connected to a metering device, in each case acid monomer being initially introduced into the metering device and polyether macromonomer and water into the polymerization reactor, acid monomer being metered from the metering device into the polymerization reactor, the metering of the acid monomer into the polymerization reactor being effected in such a way that first a polymerization pH is established in the aqueous medium and then, until the conversion of 70 mol % of the polyether macromonomer initially introduced into the polymerization reactor, acid monomer is passed into the polymerization reactor in an amount per unit time such that the pH in the aqueous medium deviates by not more than ±0.3 from the initially established polymerization pH.
