An article is described including an article surface, a primer coating or layer of SiOx, SiOCor SiNCapplied to the article surface, and a deposit of lubricant applied to the primer coating or layer. The primer coating or layer of SiO, SiOCor SiNCis applied by chemical vapor deposition of a polysiloxane or polysilazane precursor in the presence of oxygen. A first deposit of lubricant is applied to the primer coating or layer. The primer coating or layer improves the adhesion or wetting of the lubricant on the surface to be lubricated. Examples of such an article are a prefilled syringe having a barrel with a lubricated interior portion and a plunger tip that slides along it. Another example of such an article is a vial having a lubricated opening to receive a septum. Another aspect of the invention is a method of making such an article.

Ceramic honeycomb structures and methods to make the same are disclosed. The structures may be comprised of at least two separate smaller ceramic honeycombs that have been coated with a polymer to create a polymeric barrier coating and adhered together with a cement comprised of inorganic fibers and a binding phase which is comprised of amorphous silicate, aluminite or alumino silicate glass and other inorganic particles. The polymer is selected such that it is penetratable into or covering the pores in the honeycomb structure to form a thin barrier layer thereon to mitigate migration of the inorganic fibers, binding phase and water into the pores. The polymer is adapted to be burned off or decomposed at or below cement and honeycomb skin firing temperatures, or at or below honeycomb operating temperatures during application to create a honeycomb structure that, when formed into an exhaust filter, does not have any undesired pressure drop increase due to cement migration.

An improved soot catalyst is comprised of an alkali compound at least partially coated by a ceramic coating comprised of C bonded to a metal, semimetallic element or combination thereof. The improved soot catalyst may be employed in catalyzed Diesel particulate filters. In one method to make a catalyzed Diesel particulate filter, the improved filter is made by contacting a porous ceramic body having an alkali catalyst thereon, coating the alkali catalyst with an organic ceramic precursor, heating the ceramic body to a temperature in an atmosphere sufficient to decompose the organic ceramic precursor to form the soot catalyst on the porous ceramic body without volatilizing substantial amount of the alkali catalyst away.

A dielectric coating is provided which has both a dielectric constant greater than 2.5 and a hydrophobic surface. The dielectric coating may be provided by plasma enhanced chemical vapor deposition (PECVD) of organosilane, organosiloxane, organosilazane, organometallic, and/or hydrocarbon precursors. Methods are also provided for altering the contact angle of a liquid in contact with the dielectric coating, e.g., for electrowetting applications.

Dielectric coatings for electrowetting applications

Compounds of ethynyl aromatic compounds form polymers which have high thermal stability. The monomers are useful for coating a wide variety of substances such as dielectric coatings where high thermal resistance is desirable including electronic components such as computer chips.

Ethynyl substituted aromatic compounds, synthesis, polymers and uses

An oligomer, uncured polymer or cured polymer comprising the reaction product of one or more polyfunctional compounds containing two or more cyclopentadienone groups and at least one polyfunctional compound containing two or more aromatic acetylene groups wherein at least some of the polyfunctional compounds contain three or more reactive groups. Such oligomers and uncured polymers may be cured to form cured polymers which are useful as dielectrics in the microelectronics industry, especially for dielectrics in integrated circuits.

Described is a method for preparing a polybenzazole filament which comprises extruding a polybenzazole dope filament, drawing the filament across an air gap, coagulating and washing the filament, and drying the filament, characterized in that a solution of a compound selected from the group consisting of ferrocenes, ruthocene, iodide-, cobalt-, and copper-containing compounds, dyes, and mixtures thereof is contacted with a filament subsequent to the washing step and prior to the drying step. This method provides a means to improve the tensile strength retention of damaged polybenzazole filaments following exposure to sunlight.

An on-line multidimensional system which includes a liquid chromatograph having an on-line connection to a pyrolysis probe, which in turn has on-line connection to a gas chromatograph. Preferred applications use a size-exclusion chromatograph coupled to a pyrolysis probe coupled to a gas chromatograph to simultaneously produce composition as a function of molecular weight/size information for polymeric materials.
