International Classification:

B05D001/36
B32B001/00

US Classification:

427214, 427215, 427220, 428402, 428403, 428404, 428407

Abstract:

A new class of surface modified particles and a multi-step Michael-type addition surface modification process for the preparation of the same is provided. The multi-step Michael-type addition surface modification process involves two or more reactions to compatibilize particles with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through reactive organic linking groups. Specifically, these reactive groups are activated carbon—carbon pi bonds and carbon and non-carbon nucleophiles that react via Michael or Michael-type additions.

Abstract:

The present invention relates to a new class of surface modified particles and to a multi-step surface modification process for the preparation of the same. The multi-step surface functionalization process involves two or more reactions to produce particles that are compatible with various host systems and/or to provide the particles with particular chemical reactivities. The initial step comprises the attachment of a small organic compound to the surface of the inorganic particle. The subsequent steps attach additional compounds to the previously attached organic compounds through organic linking groups.

Abstract:

Surface-modified nanoparticles of boehmite, and methods for preparing the same. Aluminum oxyhydroxide nanoparticles are surface modified by reaction with selected amounts of organic acids. In particular, the nanoparticle surface is modified by reactions with two or more different carboxylic acids, at least one of which is an organic carboxylic acid. The product is a surface modified boehmite nanoparticle that has an inorganic aluminum oxyhydroxide core, or part aluminum oxyhydroxide core and a surface-bonded organic shell. Organic carboxylic acids of this invention contain at least one carboxylic acid group and one carbon-hydrogen bond. One embodiment of this invention provides boehmite nanoparticles that have been surface modified with two or more acids one of which additional carries at least one reactive functional group. Another embodiment of this invention provides boehmite nanoparticles that have been surface modified with multiple acids one of which has molecular weight or average molecular weight greater than or equal to 500 Daltons. Yet, another embodiment of this invention provides boehmite nanoparticles that are surface modified with two or more acids one of which is hydrophobic in nature and has solubility in water of less than 15 by weight.

International Classification:

G06F 16/951
H04L 29/08
G06F 16/182

Abstract:

A method, system and computer program product for sharing resources among remote repositories. In a shared file system, a resource identifier and metadata are created for a resource, where the resource identifier is stored in a lock file in a shared volume accessible by the remote repositories. The lock file is then released in response to distributing the associated resource to the remote repositories. Alternatively, in a peer-to-peer system, a request is received to create, read, update or delete a resource stored in a content repository. A resource name, a resource version and/or a resource fingerprint are received in connection with the request to create, read, update or delete the resource in the content repository. A determination is then made as to whether the received resource name, resource version and/or resource fingerprint matches the respective resource name, resource version and/or resource fingerprint stored in a node graph for the resource.
