The description includes materials that may be useful for fuel cell applications such as in the manufacture of fuel cell electrodes, proton exchange membranes (PEM), as catalyst additives or in tie layers designed to be thermally and chemically robust while operating within a fuel cell's harsh environment at higher temperatures and to conduct protons, with significantly higher levels of bound acidic groups, while in a low hydration state. Methods of making the materials are also described.

Proton conducting materials

Materials are provided that may be useful as ionomers or polymer ionomers, including compounds including bis sulfonyl imide groups which may be highly fluorinated and may be polymers.

Orthodontic adhesives and packaged articles including an orthodontic appliance having a base for bonding the appliance to a tooth are disclosed. In the packaged articles, an adhesive is on the base of the appliance, and a container at least partially surrounds the orthodontic appliance having adhesive on the base thereof.

An alignment structure useful in a liquid crystal display device comprising a substrate having disposed thereon an oriented layer of a chromonic liquid crystalline material, wherein the chromonic liquid crystalline material comprises a chromonic material, a pre-tilt additive, and/or a cross-linking agent. The structure can be made by coating the chromonic liquid crystalline material onto the substrate and then drying or curing the coated substrate. The alignment structure can also include one or more polarizing dyes or other additives and can thus be made to perform polarizing, retarding and/or color filtering functions in addition to alignment and orientation functions. Liquid crystal displays containing such alignment structures and methods of making such displays are also described.

Stabilized liquid crystal alignment structure with pre-tilt angle and display devices containing the same

The present invention provides a shaped permeable polymeric material including a hydrophobic portion and a hydrophilic portion, wherein the material is crosslinked. This material is prepared by a method including the steps preparing a crosslinkable composition having a hydrophobic portion and a hydrophilic portion; placing the crosslinkable composition in a mold; gelling the crosslinkable composition to form a shaped gelled polymeric composition comprising a hydrophobic portion, a hydrophilic portion, and a liquid portion; and exchanging the liquid portion with an exchange liquid to form the permeable polymeric material. Preferably this material is used in a blood gas sensor.
