Nanoparticle Paste Formulations And Methods For Production And Use Thereof

View page
US Patent:
20130209692, Aug 15, 2013
Filed:
Feb 11, 2013
Appl. No.:
13/764669
Inventors:
LOCKHEED MARTIN CORPORATION - , US
Andrew Fried - Saint Paul MN, US
Tim Stachowiak - Austin TX, US
Jerome Chang - San Jose CA, US
Randall Mark Stoltenberg - Palo Alto CA, US
Assignee:
LOCKHEED MARTIN CORPORATION - Bethesda MD
International Classification:
H01B 1/02
US Classification:
4273766, 252512
Abstract:
Nanoparticle paste formulations can be configured to maintain a fluid state, promote dispensation, and mitigate crack formation during nanoparticle fusion. Such nanoparticle paste formulations can contain an organic matrix and a plurality of metal nanoparticles dispersed in the organic matrix, where the plurality of metal nanoparticles constitute about 30% to about 90% of the nanoparticle paste formulation by weight. The nanoparticle paste formulations can maintain a fluid state and be dispensable through a micron-size aperture. The organic matrix can contain one or more organic solvents, such as the combination of one or more hydrocarbons, one or more alcohols, one or more amines, and one or more organic acids. Optionally, the nanoparticle paste formulations can contain about 0.01 to about 15 percent by weight micron-scale metal particles or other additives.

Appl. No.:
17/759639
Inventors:
- San Jose CA, US
Randall M. STOLTENBERG - Palo Alto CA, US
Assignee:
KUPRION INC. - San Jose CA
International Classification:
B01D 39/16
A41D 13/11
B01D 39/18
Abstract:
Metal nanoparticle agglomerates may convey biocidal activity to surfaces upon which they are deposited and become adhered, such as various air filtration media. Air filtration media may comprise a plurality of fibers having a plurality of metal nanoparticle agglomerates adhered thereto. The metal nanoparticle agglomerates may comprise a plurality of fused, partially fused, or unfused metal nanoparticles that are associated with one another upon a surface of the plurality of the fibers. Suitable metal nanoparticles for promoting biocidal activity against various pathogens, such as viruses and bacteria, may include copper nanoparticles and/or silver nanoparticles. Masks, inline filters, and air filtration systems may incorporate the air filtration media.

US Patent:
20230051591, Feb 16, 2023
Filed:
Aug 11, 2022
Appl. No.:
17/819069
Inventors:
- San Jose CA, US
Rachel BRODY - Garden Valley CA, US
Randall M. STOLTENBERG - Palo Alto CA, US
Robert ROTH - San Jose CA, US

Assignee:
Kuprion, Inc. - San Jose CA
International Classification:
C09D 5/14
C09D 7/40
C08K 3/08
B82Y 30/00
B82Y 40/00
C09D 7/61
Abstract:
Metal nanoparticle agglomerates may render the surface of an article biocidal toward microorganisms. Articles having a biocidal surface may comprise a coating comprising metal nanoparticle agglomerates adhered via an adhesive to at least a portion of a surface of the article. A coating formulation comprising metal nanoparticle agglomerates may be applied to the surface of an article to accomplish the foregoing.

Processes For Forming Composite Structures With A Two-Dimensional Material Using A Porous, Non-Sacrificial Supporting Layer

US Patent:
20150217219, Aug 6, 2015
Filed:
Jan 29, 2015
Appl. No.:
14/609325
Inventors:
- Bethesda MD, US
Peter V. BEDWORTH - Los Gatos CA, US
David Francis CASEY, JR. - Voorhees NJ, US
Scott E. HEISE - San Jose CA, US
Steven W. SINTON - Palo Alto CA, US

International Classification:
B01D 39/20
B01D 46/00
B01D 67/00
B01D 39/16
Abstract:
It can be difficult to remove atomically thin films, such as graphene, graphene-based material and other two-dimensional materials, from a growth substrate and then to transfer the thin films to a secondary substrate. Tearing and conformality issues can arise during the removal and transfer processes. Processes for forming a composite structure by manipulating a two-dimensional material, such as graphene or graphene-base material, can include: providing a two-dimensional material adhered to a growth substrate; depositing a supporting layer on the two-dimensional material while the two-dimensional material is adhered to the growth substrate; and releasing the two-dimensional material from the growth substrate, the two-dimensional material remaining in contact with the supporting layer following release of the two-dimensional material from the growth substrate.

Conformable And Adhesive Solid Compositions Formed From Metal Nanoparticles And Methods For Their Production And Use

View page
US Patent:
20140374079, Dec 25, 2014
Filed:
Jun 16, 2014
Appl. No.:
14/306085
Inventors:
- Bethesda MD, US
Jerome Chang - San Jose CA, US
Randall Mark Stoltenberg - Palo Alto CA, US
International Classification:
C09K 5/14
C09J 11/04
F28F 21/00
US Classification:
165185, 252 75
Abstract:
Materials that readily adhere to and conform to various surfaces can be desirable for a number of applications. In heat transfer and thermal management applications, for example, conformable materials can be used in establishing a thermal interface between a heat source and a heat sink. There are limited materials that provide good thermal conductivity values while maintaining capabilities to readily adhere and conform to a surface. Compositions including a conformable and adhesive solid can include a reaction product formed by heating a mixture containing a plurality of metal nanoparticles, one or more amines, and one or more carboxylic acids. The compositions can further include one or more additives dispersed in the conformable and adhesive solid.
