The present application is directed to mesoporous carbon materials comprising bi-functional catalysts. The mesoporous carbon materials find utility in any number of electrical devices, for example, in lithium-air batteries. Methods for making the disclosed carbon materials, and devices comprising the same, are also disclosed.

The invention discloses fluorine-containing bi-functional microspheres and application thereof. The fluorine-containing bi-functional microspheres have a structure shown as a formula (I), wherein B is crosslinked polymer microspheres, silicon dioxide microspheres, aluminum oxide microparticles or ferroferric oxide microparticles; g represents grafting; FL is a structural unit containing fluorine element; G is a structural unit containing hydroxyl, amido, carboxyl or an epoxy group; A is a structural unit containing hydroxyl, amido, carboxyl or an epoxy group; E1 and E2 are hydrogen, halogen or sulfydryl; x is 0 or 1; y is 0 or 1; and m is a natural number more than or equal to 0, and n is a natural number more than or equal to 0. The fluorine-containing bi-functional microspheres can be used for modifying surfaces of materials to form a hydrophobic and oleophobic coating. In the process of fluorination modification of the microspheres, a certain amount of hydroxyl and carboxyl are retained, and the microspheres are fixed on the surfaces of the materials under the action of a covalent bond of the retained hydroxyl and carboxyl and an adhesive, so that the stability of the coating is improved and the coating is not easy to fall off and deform.

A process for preparing bi-functional catalyst for Fluid Catalytic Cracking (FCC), that comprises molecular sieves, modified clay and semi-basic alumina and the catalyst for highly effective cracking of high boiling petroleum feedstock to provide simultaneously, enhanced yields of Liquefied Petroleum Gas (LPG) and reduction of undesirable bottoms.

A bifunctional LED headlamp for a vehicle is disclosed, wherein at least one of a shield, a lens, a reflector, and an LED are movable to facilitate use of the headlamp in both a low beam mode and a high beam mode.

The invention relates to a process for the manufacture of a waterborne multistage polymer dispersion that has ethylenically unsaturated functional groups for crosslinking. The process comprises the steps of;a. making an aqueous emulsion or solution of a first stage polymer comprising carboxylic acid functionalized monomers to an amount sufficient to make the first stage polymer water soluble or dispersible,b. at least partially neutralizing the first stage polymer with a base,c. forming a two-stage polymer dispersion by adding to the at least partially neutralized first stage polymer a second stage monomer mixture and emulsion polymerizing said second stage monomer mixture to a second stage polymer which is less hydrophilic than the first stage polymer,d. reacting with the obtained two-stage polymer dispersion a bi-functional compound comprising an ethylenically unsaturated group and a group reactive towards the carboxylic acid in the two-stage polymer.The invention further relates to a water-borne curable multistage polymer dispersion, to coating compositions.

A hydrogel-metal assembly is provided. An intervening polymer network is used to bond together a water-swollen hydrogel layer and a biocompatible surface-modified metallic layer. The hydrogel layer is a water-swollen hydrogel layer of at least two interpenetrating polymers. The surface of the biocompatible surface-modified metallic layer is surface-modified with an inorganic material. The intervening polymer network has been chemically grafted to the inorganic material of the biocompatible surface-modified metallic layer through bi-functional linker molecules. The intervening polymer network is further physically or chemically cross-linked with the polymers of the water-swollen hydrogel. The hydrogel-metal assembly can be adapted to form a medical device, medical implant, an artificial implant, an orthopedic implant, or at least as part of a joint. The hydrogel-metal assembly is attractive for use as such implants or devices due to its characteristics such as, for example, low coefficient of friction, impact-absorption capacity or strength, and / or biocompatibility.

A bi-functional collar guard includes two elongated narrow parts and a wide part disposed between the elongated narrow parts, wherein the bi-functional collar guard removably outfits a neckline of clothing by placing a folded part inside the clothing and thereby aligning an upper part of the bi-functional collar guard substantially parallel to an outer part of the neckline such that a fold line of the bi-functional collar guard coincides with the outer part of the neckline.
