The present methods provide tools for growing conformal metal thin films, including metal nitride, metal carbide and metal nitride carbide thin films. In particular, methods are provided for growing such films from aggressive chemicals. The amount of corrosive chemical compounds, such as hydrogen halides, is reduced during the deposition of transition metal, transition metal carbide, transition metal nitride and transition metal nitride carbide thin films on various surfaces, such as metals and oxides. Getter compounds protect surfaces sensitive to hydrogen halides and ammonium halides, such as aluminum, copper, silicon oxide and the layers being deposited, against corrosion. Nanolaminate structures incorporating metallic thin films, and methods for forming the same, are also disclosed.

The present invention relates to ionic silicone hydrogel polymers displaying improved lysozyme uptake, low contact angle and reduced water soluble polymeric ammonium salt uptake.

Infrared absorbing N-alkylsulfate cyanine compounds and imageable compositions containing the compounds are disclosed. The compounds have the structure I: in which:R is hydrogen, or R is one or more alkyl, substituted or unsubstituted aralkyl, alkoxy, carboxyl, nitro, cyano, trifluoromethyl, acyl, alkyl sulfonyl, aryl sulfonyl, or halogen groups, or R is the atoms necessary to form a substituted or unsubstituted benzo group;A is (CH2)n; where n is 1–5; preferably 2–4;Y is O, S, NR′, or C(R′)2, where R′ is hydrogen or alkyl; preferably methyl;Z is hydrogen, halogen, alkyl, substituted or unsubstituted aralkyl; substituted or unsubstituted aroxyl, substituted or unsubstituted thioaroxyl, or substituted or unsubstituted diphenylamino;m is zero or one; andX is a cation, preferably sodium, potassium, lithium, ammonium, or substituted ammonium.

This invention relates to a rubber composition which contains intercalated and at least partially exfoliated organophillic clay reinforcement formed in situ within the elastomer host from a hydrophilic clay. The invention particularly relates to an in situ modification of a hydrophilic clay to compatibilize the clay with a diene-based elastomer. The clay is converted from being hydrophilic in nature to being more hydrophobic in nature and therefore more compatible with the elastomer by bulk blending the elastomer host with a smectite clay, preferably a montmorillonite or hectorite clay, and a hydrocarbyl onium salt, such as for example a quaternary ammonium salt, and particularly in the absence of water addition to the elastomer host. Therefore, such in situ procedure of intercalation and at least partially exfoliation relies upon a bulk blending thereof with an elastomer host at an elevated temperature and under high shear conditions in contrast to pre-intercalating the clay in an aqueous based medium and in contrast to simple low viscosity melt processing of a thermoplastic polymer. The invention also relates to articles of manufacture, including tires, having at least one component comprised of such rubber composition. Such tire component may be, for example, a tire tread.
