26270 results about "Ammonium" patented technology

The ammonium cation is a positively charged polyatomic ion with the chemical formula NH⁺₄. It is formed by the protonation of ammonia (NH₃). Ammonium is also a general name for positively charged or protonated substituted amines and quaternary ammonium cations (NR⁺₄), where one or more hydrogen atoms are replaced by organic groups (indicated by R).

Metal nitride deposition by ALD with reduction pulse

The present methods provide tools for growing conformal metal thin films, including metal nitride, metal carbide and metal nitride carbide thin films. In particular, methods are provided for growing such films from aggressive chemicals. The amount of corrosive chemical compounds, such as hydrogen halides, is reduced during the deposition of transition metal, transition metal carbide, transition metal nitride and transition metal nitride carbide thin films on various surfaces, such as metals and oxides. Getter compounds protect surfaces sensitive to hydrogen halides and ammonium halides, such as aluminum, copper, silicon oxide and the layers being deposited, against corrosion. Nanolaminate structures incorporating metallic thin films, and methods for forming the same, are also disclosed.

Perfumed liquid laundry detergent compositions with functionalized silicone fabric care agents

The invention is directed to aqueous liquid laundry detergent compositions for cleaning and imparting fabric care benefits to fabrics laundered therewith and to methods for preparing such compositions. Such compositions comprise (A) at least one textile-cleaning surfactant; (B) droplets of miscible silicones comprising both a polarly-functionalized, preferably nitrogen-containing amino or ammonium functionalized, polysiloxane component and a nitrogen-free non-functionalized or non-polarly-functionalized polysiloxane component; and (C) a perfume component comprising fragrant aldehydes and / or ketones or a pro-perfume capable of providing such aldheyde and / or ketone perfume materials in situ. Incorporation of a polarly-functionalized polysiloxane fabric care agent into liquid laundry detergent compositions by miscibly combining it with a non-functionalized or non-polarly functionalized polysiloxane minimizes the undesirable interaction such polarly-functionalized silicone material might otherwise have with aldehyde and / or ketone perfume compounds.

Inherently antimicrobial quaternary amine hydrogel wound dressings

A composition and method for treating a wound with an inherently antimicrobial dressing. The dressing is a hydrogel containing from about 15 to 95 percent, and preferably from about 61 to 90 percent, by weight of a cationic quaternary amine acrylate polymer prepared by the polymerization of acryloyloxyethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts or acrylamidoethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts. The antimicrobial hydrogels are non-irritating to the wound, absorb wound exudate, and, due to the inherently antimicrobial properties, enhance the sterile environment around the wound. The hydrogels have sufficient adhesive properties that loose contact with the wound is assured but can also be removed without leaving any gel residue on the wound. The wound dressings are preferably formed on a substrate, such as a web or patch, for ease in application to and removal from the wound. If desired, additional antimicrobial or other pharmaceutically active agents can also be incorporated into the hydrogel structure.

Preparation of elastomer with exfoliated clay and article with composition thereof

This invention relates to a rubber composition which contains intercalated and at least partially exfoliated organophillic clay reinforcement formed in situ within the elastomer host from a hydrophilic clay. The invention particularly relates to an in situ modification of a hydrophilic clay to compatibilize the clay with a diene-based elastomer. The clay is converted from being hydrophilic in nature to being more hydrophobic in nature and therefore more compatible with the elastomer by bulk blending the elastomer host with a smectite clay, preferably a montmorillonite or hectorite clay, and a hydrocarbyl onium salt, such as for example a quaternary ammonium salt, and particularly in the absence of water addition to the elastomer host. Therefore, such in situ procedure of intercalation and at least partially exfoliation relies upon a bulk blending thereof with an elastomer host at an elevated temperature and under high shear conditions in contrast to pre-intercalating the clay in an aqueous based medium and in contrast to simple low viscosity melt processing of a thermoplastic polymer. The invention also relates to articles of manufacture, including tires, having at least one component comprised of such rubber composition. Such tire component may be, for example, a tire tread.
