Philippe Sellenet - Nancy, FR

International Classification:

A61K 31/787
C12Q 1/18

US Classification:

424078300, 435032000

Abstract:

A bactericidal polymeric composition includes a hydrophilic first comonomer copolymerized to a second comonomer to produce a polymeric composition that is more hydrophilic or more bactericidal in an aqueous solution than either of the comonomers alone. Methods for identifying bactericidal polymers, methods for rendering materials bactericidal, and methods for using bactericidal compositions to kill or reduce bacterial growth are also described. Applications for the inventive compositions include their use in catheters, stents, medical devices, contact lenses; root canal fillers; and/or wound dressings.

International Classification:

C08F 216/06
C08F 265/02
C08F 265/04

US Classification:

525 59, 525301, 525302

Abstract:

A copolymer comprises a first monomer including a hydrophilic group and a hydrophobic group linked to the hydrophilic group, and a second monomer polymerized to the first monomer. The hydrophobic group is oil-repellant. A receding contact angle of a low surface energy fluid on the copolymer is greater than an advancing contact angle of a high surface energy fluid on the copolymer.

Abstract:

A bactericidal or antimicrobial polymeric composition includes a hydrophilic first comonomer copolymerized to a second comonomer to produce a polymeric composition that is more hydrophilic or more bactericidal or antimicrobial in an aqueous solution than either of the comonomers alone. Methods for identifying bactericidal or antimicrobial polymers, methods for rendering materials bactericidal or antimicrobial, and methods for using bactericidal or antimicrobial compositions to kill or reduce bacterial or microbial growth are also described. Applications for the inventive compositions include their use in catheters, stents, medical devices, contact lenses; root canal fillers; fibers; paper; and/or wound dressing.

International Classification:

F28F 9/02
F28F 21/04
F28D 9/00

Abstract:

Devices and methods for fabrication of a multiscale porous high-temperature heat exchanger for high-temperature and high-pressure applications are disclosed. The heat exchanger can include a core with macrochannels formed in a checkerboard pattern to facilitate alternative flow of working fluid having hot and cold temperatures between adjacent macrochannels. Each macrochannel can include a two-dimensional microchannel array that further distributes flow throughout the heat exchanger to enhance heat transfer and mechanical strength without significant pressure drop penalty. The heat exchanger can further include a header integrated therewith to distribute working fluid flowing through the heat exchanger through the outlets such that it flows evenly therethrough. Methods of fabricating heat exchangers of this nature are also disclosed.

Abstract:

In some examples, an article may include a substrate and a coating on the substrate. The substrate may include a superalloy, a ceramic, or a ceramic matrix composite. The coating may include a layer comprising a matrix material and a plurality of nanoparticles. The matrix material may include at least one of silica, zirconia, alumina, titania, or chromia, and the plurality of nanoparticles may include nanoparticles including at least one of yttria, zirconia, alumina, or chromia. In some examples, an average diameter of the nanoparticles is less than about 400 nm.

International Classification:

C09D 127/12
H01B 9/00
C09K 3/18

Abstract:

A durable coating which reduces ice adhesion and minimizes ice accumulation includes a polymeric binder and a film forming lubricant. The polymeric binder is selected from a fluoropolymer or silicone polymer having one or more reactive groups. The film forming lubricant is a lubricous fluoropolymer or silicone polymer. Methods of applying a durable coating are also disclosed.
