Abstract:
This invention relates to regenerable antimicrobial coatings with long-lasting efficacy for use in medical applications including implants, medical instruments or devices, and hospital equipment. The same coatings would also have broad utility in the consumer, industrial, and institutional markets. The coating technology would be based on sequestration of hydrogen peroxide (HP) by zinc oxide binders incorporated into the coatings.
Abstract:
A novel metal polyoxide is a compound in which a plurality of oxygen elements are coupled to a transition metal element, and shows surface electrical resistance in addition to antibacterial and deodorizing activities. More specifically, the metal polyoxide contains manganese (III) molybdate and cobalt (III) molybdate having a novel structure. A preparation method thereof and a preparation method of a functional fiber or textile prepared using the same are provided.
Abstract:
Embodiments herein provide a nanoparticle, such as a metal nanoparticle, coupled to a linker molecule to form a nanoparticle-linker construct. In an embodiment, a nanoparticle-linker construct may be further bound to a substrate to take advantage of one or more properties of the nanoparticle. In an embodiment, a functionalized nanoparticle (a nanoparticle having a reactive functionality) may be bound to a linker to form a functionalized nanoparticle-linker construct which may in-turn be bound to a substrate.
Abstract:
The invention relates to “closed loop” processes, systems and compositions for providing flame retardant properties to substrates containing at least about 5 weight percent of non-thermoplastic material, such as non-thermoplastic fibers, fibrous compositions or fabrics, and to treated substrates. The processes and systems are environmentally friendly, and advantageously conserve chemical compounds and water by recycling flame retardant composition.The processes of the invention generally comprise: (a) applying a flame retardant composition containing one or more flame retardant substances, an aqueous liquid and one or more adhesion agents to substrates; (b) removing excess flame retardant composition from the substrates; (c) permitting the substrates to dry to a low moisture content; and (d) recycling excess flame retardant composition; wherein the flame retardant composition does not contain an amount of a dye or other agent that could contaminate the flame retardant composition.A preferred “closed loop” system of the invention is shown in FIG. 1.

Abstract:
Electrical separators for batteries, especially lithium batteries, having a shutdown mechanism. A process for their production. An electrical separator is used in batteries and other systems in which electrodes have to be separated from each other while maintaining ion conductivity. Safety is very important in lithium batteries, since in contrast to other types of battery (Pb, NiCd, NiMeH) the solvent for the electrolyte is not water but a combustible solvent. A separator for lithium cells must possess a shutdown mechanism while not being able to melt down. This is achieved by an electrical separator having a shutdown layer which comprises particles which melt at a desired temperature, close the pores of the separator, and so stop ion flow. Since the separator also comprises a porous inorganic (ceramic) layer on a carrier, the cells cannot melt down as a result of a completely melted separator.
Abstract:
The invention concerns moisture-regulating composites comprising a sheetlike carrier material, a water-soluble hygroscopic substance and a water-absorbing polymer polymerized onto the carrier material in the presence of the hygroscopic substance, methods of making them and their use for moisture regulation.
Abstract:
A closed-loop system and process is used for applying fire retardant chemicals to substrates including fibers, yarns, fabrics or mixtures thereof. Substrates are preferably positioned in a vessel such as a dye machine which circulates the fire retardant chemicals. After absorption of the fire retardant composition, non-absorbed fire retardant chemicals are recovered and re-used on subsequent batches of fibers. The re-use of fire retardant chemicals can take place in the same vessel which is used to treat successive batches of substrates. Alternatively, recovery can be achieved by directing the non-absorbed fire retardant composition into a second dye machine containing additional fibers, or by extracting the fire retardant composition by centrifugation or other means, or by a combination of the two processes. The process is environmentally friendly, and allows for higher throughput on impregnating fibers with fire retardant chemicals.

Abstract:
The invention relates to a method for removing a contaminant from a gas phase or a liquid phase by contacting an article composed of (1) a fabric or cellulosic fiber and (2) a polyoxometalate, wherein the polyoxometalate is incorporated in the fabric or cellulosic fiber, with the gas phase or liquid phase containing the contaminant. The invention further relates to a polyoxometalate-modified fabric composed of a fabric and a polyoxometalate of the present invention incorporated in the fabric. The invention further relates to an article containing the polyoxometalate-modified fabric. The invention further relates to a method for making the polyoxometalate-modified fabric, by contacting the fabric with a polyoxometalate to produce a polyoxometalate-modified fabric.
