Abstract: A system is provided wherein a plug flow reactor is used to make combinatorial libraries of materials. Examples of plug flow reactors include stirred tube reactors, extruders, and static mixers.

Abstract: Polymerizable compositions that include: (a) a cationically active functional group; (b) an initiation system capable of initiating cationic polymerization of the cationically active functional group; and (c) a filler composition that includes various radiopacifying fillers in an amount sufficient to render the polymerizable composition radiopaque. Components (a), (b), and (c) are selected such that the polymerizable composition polymerizes to form a polymerized composition having a Barcol hardness, measured using a GYZJ-935 meter, of at least 10 within 30 minutes following initiation of the cationically active functional group at a reaction temperature of 25° C.

Abstract: A hardenable medical composition (preferably, dental composition) that includes an ionic redox polymerization system and at least one secondary ionic salt that includes a cation selected from the group consisting of a Group I ion, a Group II ion, an ammonium ion of the formula NR4+ wherein each R is H or a (C1–C4)alkyl group, and mixtures thereof.

Abstract: A dental restorative formula selector including a formula matrix is disclosed. The formula matrix includes tooth shade markings and two or more dental restorative formulas correlated to each tooth shade marking. Each dental restorative formula includes at least one dental restorative composition code, and at least one dental restorative formula of the two or more dental restorative formulas provided includes at least two dental restorative composition codes. The dental restorative formula selector may provide a practitioner with multiple dental restorative formula options for restoring teeth using dental restorative compositions.

Abstract: Disclosed are block copolymers and end-functionalized polymers containing in their backbones at least one fluoro alkyl (meth)acrylate mer unit comprising —C6F13, —C4F9, or —C3F7.

Abstract: A dental material comprising a hardenable resin and silica particles dispersed within the hardenable resin, wherein the silica particles have an average diameter of less than about 200 nm and are present in an amount greater than about 40 wt % of the weight of the dental material. The dental material may further comprise a heavy metal oxide. The dental material can be used as dental adhesives, artificial crowns, anterior or posterior fillings, casting materials, cavity liners, cements, coating compositions, mill blanks, orthodontic devices, restoratives, prostheses, and sealants.

Abstract: The application discloses methods of plasma treatment that employ an ion sheath in a capacitively-coupled system to increase the hydrophilicity of porous articles, including microporous articles having pore sizes of 0.05 to 1.5 micrometers, both on their surfaces and in their pores such that the articles' bulk wetting properties are improved.

Abstract: A polycrystalline translucent aluminum oxide ceramic material having an average grain size of no greater than 1.0 micron and a Contrast Ratio value of less than about 0.7. The material can be in the form of a dental mill blank, dental prosthesis or other dental article or non-dental article.

Abstract: The present invention discloses methods of controlling the puncturability, and optionally the sealability (the ability of a film to conform around a puncturing object) and resealability (the ability of a film to close a hole made by a puncturing object), of polymeric films. Systems comprising a film and puncturing object are also disclosed. Puncturability is controlled by achieving targeted levels of the friction between the film and a puncturing object, the film's flexural rigidity, the film's recovering stress, and the film's elongation at break.

Abstract: The present invention relates to a double-sided pressure sensitive adhesive foam tape. In certain embodiments the foam tape does not require the use of a release liner. Elimination of the release liner reduces the cost of the tape and also avoids problems associated with damage to the liner during traditional tape manufacturing from exposure to e-beam radiation.

Abstract: A self-venting movable seal and plunger assembly for use in dispensing materials from cylindrical bodies is disclosed. The assembly includes a self-venting movable seal and a plunger tip that seats within a plunger tip pocket in the movable seal, occluding a vent in the movable seal. Methods of using the assembly to dispense materials are also disclosed.

Abstract: Method of making a lens on an optical fiber or waveguide using a femtosecond laser. The lens may be further smoothed by the application of heat.
