A process for the treatment of a photopolymer material that constitutes matrix plates in flexographic printing includes: shredding and refining the matrix plates into pieces and subsequent cold grinding to obtain a powder; mixing the powder with a thermosetting resin and an amine hardener; carrying out a first phase of turbomixing; carrying out a first phase of cooling; carrying out a second phase of turbomixing; carrying out a second cooling phase; mixing the mixture in a cooling unit; adding an amine catalyst for thermosetting resins; inserting into a vacuum gauge; pouring the mixture into a mold; subjecting the mixture to two post-polymerization cycles in an oven.

Electrochemical cells that cycle lithium ions and methods for suppressing or minimizing dendrite formation are provided. The electrochemical cells include a positive electrode, a negative electrode, and a separator disposed therebetween. At least one transition metal ion-trapping moiety, including one or more polymers functionalized with one or more trapping groups, may be included within the electrochemical cell as a coating, pore filler, substitute pendant group, or binder. The one or more trapping groups may be selected from the group consisting of: crown ethers, siderophores, bactins, ortho-phenanthroline, iminodiacetic acid dilithium salt, oxalates malonates, fumarates, succinates, itaconates, phosphonates, and combinations thereof, and may bind to metal ions found within the electrochemical cell to minimize or suppress formation of dendrite protrusions on the negative electrode.

The present application provides compositions, methods of making the compositions, methods of using the compositions, and kits having instructions for using the compositions for providing a bond between synthetic polymers or between a synthetic polymer and another type of substrate.

The disclosure provides a method for treating a surface of a carbon fiber composite material, comprising the steps of: (1) pretreating a carbon fiber reinforced resin-based composite material; (2) spraying transparent powder to the surface of the carbon fiber reinforced resin-based composite material and curing it; (3) polishing the surface of the carbon fiber reinforced resin-based composite material after the transparent powder is cured; (4) spraying transparent powder to the surface of the carbon fiber reinforced resin-based composite material after the transparent powder thereon is cured and curing it; (5) polishing, cleaning and baking; and (6) spraying a clear lacquer to the surface of the carbon fiber reinforced resin-based composite material after the transparent powder is cured and curing it.

A composite has a) a PMC layer, and b) a tile layer comprising a plurality of Ox/Ox CMC tiles each has: i) a central portion, ii) an outer portion disposed surrounding the central portion, the bottom surface of the outer portion is disposed flush with the bottom surface of the central portion, the tile layer forms a smooth continuous top surface and a smooth continuous bottom surface, and the tiles are disposed with respect to one another such that each tile is inverted with respect to an adjoining tile, and iii) one or more overlap joints formed by the overlapping of the outer portions of adjoining tiles, so that hot gases entering the smooth top surface of the tile layer between abutting outer and central periphery segments must travel laterally between the overlapping outer portions of adjoining tiles to reach the top surface of the PMC layer.

Methods for intravesical administration of a therapeutic agent including application of a photoactive nanogel to the mucosal surfaces of the bladder and/or intravesical application of cell-penetrating peptides. Photoactive nanogels may be aggregated by exposure to ultraviolet light, either in vitro or in vivo, to provide controlled or extended release of a therapeutic agent, such as an antibiotic.

Described herein is a method for producing photochromic contact lenses, in particular, photochromic silicone hydrogel contact lenses. The method comprises a step of cast molding of a lens-forming composition including an iniferter to form an unprocessed contact lens having iniferter moieties covalently incorporated into its polymer matrix and a step of iniferter-induced graft-polymerization of a photochromic vinylic monomer to the polymer matrix only in its central region which is circular and concentric with the central axis of the unprocessed contact lens. The obtained photochromic contact lens has a central pupillary region that only can undergo a reversible color change upon exposure to UV/HEVL-radiation.

Disclosed are hierarchical buoyant materials comprising porous components having multiple length scales that provide reduced density, higher strength, and improved buoyancy. The hierarchical buoyant materials include components having at least two length scales including a first porous material having elements characterized by a first linear length scale and a second porous material having elements characterized by a second linear length scale. The first porous material includes hollow microspheres, and the second porous material provides low effective density via geometrical arrangements. The second linear length scale is substantially different than the first linear length scale in terms of size, e.g., diameter, length, or distance. The second porous material is packed between the first porous material resulting in a combined material having a higher packing fraction than either the first porous material or the second porous material alone to provide reduced density, higher specific strength, and improved buoyancy per unit volume.

The present invention provides a cured film of a mixed composition of an organosilicon compound (A) including a fluoropolyether structure and an organosilicon compound (C) having an amino group or an amine skeleton, in which, when the elements constituting one side surface (W) of the cured film and amounts thereof are measured by X-ray photoelectron spectroscopy (XPS), the cured film has an F content of 60 atom % or more and an O content of 17 atom % or more.

Provided herein are liquid polymer (LP) compositions comprising a synthetic (co)polymer (e.g., an acrylamide (co)polymer), as well as methods for preparing aqueous polymer solutions by combining these LP compositions with an aqueous fluid. The resulting aqueous polymer solutions can have a concentration of a synthetic (co)polymer (e.g., an acrylamide (co)polymer) of from 50 to 15,000 ppm, and a filter ratio of 1.5 or less at 15 psi using a 1.2 m filter. Also provided are methods of using these aqueous polymer solutions in oil and gas operations, including enhanced oil recovery.
