Method For Preparing Dispersions Of Precious Metal Nanoparticles And For Isolating Such Nanoparticles From Said Dispersions

View page
US Patent:
20110064825, Mar 17, 2011
Filed:
Jan 9, 2009
Appl. No.:
12/811985
Inventors:
Dan V. Goia - Potsdam NY, US
Benjamin Morrow - Potsdam NY, US
Egon Matijevic - Potsdam NY, US
Krishna Balantrapu - Potsdam NY, US
Brendan P. Farrell - Potsdam NY, US
Assignee:
Umicore AG & Co. KG - Hanau-Wolfgang

Abstract:
The present invention is directed to a method for preparing colloidal dispersions of precious metal nanoparticles selected from the group consisting of Pt, Au, Pd, Ag, Rh, Ru and mixtures or alloys thereof, and to a method for isolating such precious metal nanoparticles from these colloidal dispersions. The colloidal dispersions are prepared by reducing suitable precious metal precursor compounds in aqueous alkaline solutions at reaction temperatures between 40 and 70 C. and a pH≧12.0 in the presence of polysaccharides with average molecular weights (M) in the range of 300,000 to 1,000,000. The precious metal nanoparticles are isolated after decomposing the polysaccharide by heating the colloidal dispersions to temperatures >80 C. The nanoparticles can be used for the manufacture of core/shell-type catalyst materials and for electronic, decorative and medical applications.

Appl. No.:
13/027306
Inventors:
Liang-Bih Lin - Carlsbad CA, US
George Cunha Cardoso - Webster NY, US
Amanda Elizabeth Preske - Rochester NY, US
Krishna Balantrapu - Marlborough MA, US
Assignee:
XEROX CORPORATION - Norwalk CT
International Classification:
H01L 31/0256
H01L 31/18
H01B 1/00
US Classification:
136263, 2525011, 438 57, 257E31001
Abstract:
A photovoltaic device includes a substrate, a first electrode, a second electrode, and an active layer between the first electrode and the second electrode.

US Patent:
20140021413, Jan 23, 2014
Filed:
Jul 20, 2012
Appl. No.:
13/554729
Inventors:
Enrique Daniel Gomez - State College PA, US
Kiarash Vakhshouri, III - State College PA, US
Seung-Hyun Lee - Marlborough MA, US
Thomas Charles Sutter - Holden MA, US
George Lyles Athens - Midland MI, US
Krishna Balantrapu - Marlborough MA, US
International Classification:
H01B 1/12
US Classification:
252500, 526256, 427 58
Abstract:
Disclosed herein is a composition comprising a regioregular polyalkylthiophene and/or a regioregular poly[2,5-bis(3-alkylthiophen-2-yl)thieno(3,2-b)thiophene]; where the composition is melted and then cooled to a temperature between a melting point and a glass transition temperature of the composition; the composition having an amount of crystallinity that is at least twice the amount of crystallinity of another identical composition that is crystallized by a method that does not involve melting and cooling to a temperature between the melting point and the glass transition temperature of the identical composition.

Methods Of Generating Managese (Iii) Ions In Mixed Aqueous Acid Solutions Using Ozone

View page
US Patent:
20200181787, Jun 11, 2020
Filed:
Oct 4, 2019
Appl. No.:
16/593397
Inventors:
- Marlborough MA, US
Katharina WEITERSHAUS - Kriens, CH
Krishna BALANTRAPU - Cambridge MA, US
International Classification:
C25C 1/10
Abstract:
Manganese-(III) species is generated and regenerated in a mixed aqueous acid solution containing manganese-(II) species by injecting ozone gas in the mixed aqueous acid solution such that ozone oxidizes at least some of the manganese-(II) species to the manganese-(III) species with at least 60% Mn(III) generation efficiency. The acids include sulfuric acid and an alkane sulfonic acid. The aqueous acid solution containing manganese-(III) and manganese-(II) species is used to etch polymer materials. The etch is a chrome-free etch method.
