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.

There is provided the reagent layer composition that can substantially reduce the measurement bias arising from hematocrits. The addition of fatty acid (4-20 carbons) and quaternary ammonium salt to a commonly used reagent layer composition composed of an enzyme, an electron transfer mediator, and several water soluble polymers not only reduce the hematocrit level-dependent bias but also provide very stable performance for an extended period of time. Disclosed are also various types of sub microliter sample volume electrochemical biosensors that are suitable to use with the reagent layer composition of present invention.

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.

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.

A topical insecticide is provided which can be safe to use and avoids many common deleterious side effects of conventional topical insecticides. The insecticide contains an insecticide and an insect growth regulator effective for killing fleas, flea larvae and flea eggs. The insecticide is formulated by dissolving an insecticidal (tetrahydro-3-furanyl) methylamine derivative or a chloronicotinyl insecticide and an insect growth regulator (IGR) in a solvent containing a quaternary ammonium salt to increase the solvency of the IGR component, thereby providing an insecticide having high insecticidal activity.

An environmentally beneficial method of producing methanol from varied sources of carbon dioxide including flue gases of fossil fuel burning power plants, industrial exhaust gases or the atmosphere itself. Converting carbon dioxide by an electrochemical reduction of carbon dioxide in a divided electrochemical cell that includes an anode in one cell compartment and a metal cathode electrode in another cell compartment that also contains an aqueous solution comprising methanol and an electrolyte of one or more alkyl ammonium halides, alkali carbonates or combinations thereof to produce therein a reaction mixture containing carbon monoxide and hydrogen which can be subsequently used to produce methanol while also producing oxygen in the cell at the anode.

The present invention provides a comprehensive solution to skin problems of infants and incontinent adults related to diaper rash, also known as diaper dermatitis. This is based on certain novel divalent metal and quaternary ammonium complexes (ion-pairs) of zeolites (that are made by an in-situ process), which in synergistic combination with certain other compositions, provide a comprehensive treatment for diaper rash that encompasses the following aspects: (1) deactivation of lipase and protease enzymes on skin surface, (2) the controlled-release delivery of skin protectant compositions, such as divalent metal zinc cation, (3) trapping of acidic and alkaline chemicals deposited on skin from body exudates and enzyme activity, (4) controlled-release delivery of anti-inflammatory agents, and COX and LOX enzyme inhibitors, (5) controlled-release delivery of antibacterial and antifungal compositions, and (6) absorption of excess moisture in the diaper zone.
