Filed:

Dec 28, 2004

Appl. No.:

11/024114

Inventors:

Stephen Carson - Coatesville PA, US
Glenn Florczak - East Brunswick NJ, US
David Russo - Audubon PA, US

International Classification:

B32B017/06

US Classification:

428432000, 427162000

Abstract:

Multi-layer solar control films composed of metal oxide, oxynitride, carbide, and/or oxycarbide layers are deposited on a substrate by atmospheric pressure chemical vapor deposition (APCVD). The film layers have alternating high/low refractive index. The coated substrate reflects near infrared (NIR) radiation, while transmitting a high level of visible radiation.

Inventors:

Nicholas J. RODAK - Princeton NJ, US
Gary J. Silverman - Chadds Ford PA, US
Stephen W. Carson - Coatesville PA, US

Assignee:

Arkema Inc. - Philadelphia PA

International Classification:

C07F 9/02

B01J 31/02
B01J 23/04

US Classification:

568 17, 502159, 502173

Abstract:

The invention relates to the use of polycyclic aromatic hydrocarbons (PAHs) such as naphthalene and its alkyl, aryl, or heteroatom substituted analogs, that act as catalysts in the presence of an alkali metal (Li, K, Na) for the reduction of electron-deficient and electron-rich triaryl phosphines to their corresponding alkali metal diaryl phosphide salts. The process is also useful for the catalysis of triaryl phosphine chalcogen adducts such as the sulfides, oxides, and selenides, diaryl(halo)phosphines, triaryl phosphine-borane adducts, and tetra-aryl bis(phosphines) that can also be reduced to their corresponding alkali metal diaryl phosphide salts. The invention also relates to small molecule PAHs and polymer tethered PAHs naphthenics.

US Classification:

257 98, 438 29, 257E33073, 257E51018, 257 40

Abstract:

A light-emitting devices and methods for forming light-emitting devices are provided. The device comprises of a substrate having a first refractive index, a transparent electrode that is coupled to an organic layer, where the transparent electrode has a second refractive index different from the first refractive index. An undercoat layer is selected that has a third refractive index to substantially match the first refractive index to the second refractive index. The undercoat layer is selected such that it has a capacity to reduce root mean square roughness of the transparent electrode film deposited. The undercoat layer is selected to improve electrical properties of the transparent electrode layer. The undercoat layer is provided between the substrate and the transparent electrode.

Assignee:

Arkema Inc. - King of Prussia PA

International Classification:

C11D 3/395

US Classification:

510372

Abstract:

The present invention relates to a liquid cleaning composition comprising a peroxygen bleach, a sulfonated anionic surfactant and an amphoteric/zwitterionic surfactant where the sulfonated anionic surfactant and the amphoteric/zwitterionic surfactants are in a ratio of from 0.1:1 to 13:1. The combination of the sulfonated anionic surfactant and the amphoteric/zwitterionic surfactants provides for high viscosities and improved cleaning performance.

Abstract:

A hydrogen peroxide composition comprises hydrogen peroxide, a stabilizer system comprising a colloidal stannate, at least one acidifying agent or a salt thereof selected from the group consisting of sulfur-containing acidifying agents, nitric acid, and mixtures and salts thereof. Optionally, the hydrogen peroxide composition comprises an organic phosphonic acid or a salt thereof, such as amino-phosphonate, and/or a free radical scavenger, such as salicylic acid. A cleaning formulation comprises the hydrogen peroxide composition, a pH adjusting agent, and optionally other additives, such as surfactants. The cleaning formulation may be made by mixing the hydrogen peroxide or a precursor thereof, water, colloidal stannate, and at least one acidifying agent, and optionally, adjusting the pH to achieve an alkaline pH.

Abstract:

Disinfectant compositions include 0.001 to 10% by weight of hydrogen peroxide or a hydrogen peroxide source based on the total weight of the composition; 0.001 to 20% by weight of at least one amphoteric surfactant based on the total weight of the composition; and 0.001 to 15% by weight of at least one alkali metal or alkaline earth metal salt of a cyclic or heterocyclic aromatic compound comprising at least one hydroxyl group, carboxylic group, or combination thereof based on the total weight of the composition. The disinfectant compositions are particularly effective at treating surfaces contaminated with resistant bacteria, such as at a fast killing rate.
