Abstract: An environmentally friendly composition and related methods of use and production of an asphalt prime coat, suitable for application to a base road structure, are described herein. The composition includes an asphaltine, and an emulsion of a natural hydrocarbon resin mixed with a penetrating component, which can include a very limited quantity an organic solvent, or can omit organic solvents. If organic solvents are omitted, a hydrophobic wax can be added for moisture retention and water impermeability. Dispersion agents can be used to facilitate penetration into the base road. Rheology modifying agents and/or alcohols can be used to add flexibility, decrease curing time, and improve thickness and viscosity. The prime coat contains a lower quantity of volatile organic compounds than conventional prime coats, reducing environmental impact. The drying time of the composition is less than alternative compositions.

Abstract: A method of making a rheology modified aqueous composition, particularly useful for drilling, milling and mining applications, is disclosed. The method includes admixing, with a clay and water, a material or materials whose constituents substantially conform to the proportions of the empirical formula M?mM?n(OH)(2m+3n+qa+br)(Aq)a(Br)b.xH2O, where M? is a divalent metal cation, M? is a trivalent metal cation, A and B are anions, and a, b, m, n, q, r, and x are defined herein. Calcined hydrotalcite and hydrotalcite-like materials are particularly preferred as starting materials. Optionally, an aluminum oxide, a nitrogen-containing compound, or both may be added. The resulting composition is preferably an elastic solid exhibiting stress-dependent fluidity, desirable temperature resistance, lubricity, inhibition of reactivity, relatively low cost, and pressure resistance. A dry composition and method of making are also disclosed.

Abstract: A rheology modified aqueous fluid composition comprising clay, water, magnesium oxide, aluminum oxide hydroxide, sodium carbonate or potassium carbonate, and calcium oxide or calcium hydroxide. The magnesium oxide and aluminum oxide hydroxide are prepared by a specific thermal treatment protocol involving heating of appropriate precursors within a specified temperature range. The pH of the composition is at least about 10. The composition is prepared by admixing the components and, optionally, sodium oxide or sodium hydroxide for pH adjustment as necessary. A substantially dry rheology modification agent comprising the enumerated components, not including the water, is also included. The resulting composition preferably exhibits shear-thinning capability including very rapid thinning upon application of shear forces and also rapid viscosification upon removal of such forces.

Abstract: In TFT (10), the channel region (15) towering over the gate electrode (14) through the gate insulation film (12), the source region (16) connecting to the channel (15) and the drain region (17) connecting to the channel region (15) on the opposite side of the source region (16) are formed on the polycrystal semiconductor film (100) on which island-like patterning is performed. An indented section (155) is formed on the surface of the channel region (15), and the section corresponding to the indented section (155) becomes the recombination center (150) which captures the small-number carrier (holes) because the degree of the crystallization is low in the section corresponding to the indented section (155) due to shift from the optimum conditions at the time of laser annealing of the semiconductor (100). Thus the invention provides a TFT and its production method which enable the stabilizing of saturation current and improving reliability by improving the film quality of the channel region.
