Compositions and methods are provided for preparing a metal substrate having a uniform textured surface with a plurality of indentations with a diameter in the nanometer and micrometer range. The textured surface is produced by exposing the substrate to an etching fluid comprising a hydrohalic acid and a mixture of a hydrohalic acid and an oxyacid, a chloride containing compound, and an oxidant. The etching solution can be used at ambient temperature. This textured surface enhances adherence of coatings or cells onto the textured surface, improves the retention of proteins on the surface, and encourages bone in-growth.

A TFT includes a zinc oxide (ZnO)-based channel layer having a plurality of semiconductor layers. An uppermost of the plurality of semiconductor layers has a Zn concentration less than that of a lower semiconductor layer to suppress an oxygen vacancy due to plasma. The uppermost semiconductor layer of the channel layer also has a tin (Sn) oxide, a chloride, a fluoride, or the like, which has a relatively stable bonding energy against plasma. The uppermost semiconductor layer is relatively strong against plasma shock and less decomposed when being exposed to plasma, thereby suppressing an increase in carrier concentration.

A well dispersed oxygen scavenging particulate compounded in a polymer matrix. The oxygen scavenging formulation consists of iron powder with a mean particle sizes within 1-25 um and pre-coated with at least one or more activating and acidifying powdered compounds, usually in the form of solid organic and inorganic salts of alkaline and alkaline earth metals such as sodium chloride and sodium bisulfate. The pre-coated iron particulate is dispersed into a polymer resin by using a conventional melt processing method such as twin-screw extrusion. The oxygen scavenging compound is mixed with polymer pellets in the solid state prior to melting. The polymer resin pellets and the coated iron powder are preferably treated with a surfactant in the dry state to help dispersing the iron / salt powder with the resin pellets. The melt extruded compounds are pelletized and kept in the dry state to prevent premature activation.

The present invention relates to a process for making durable titanium dioxide pigment by vapor phase deposition of surface treatments on the titanium dioxide particle surface by reacting titanium tetrachloride vapor, an oxygen containing gas and aluminum chloride in a plug flow reactor to form a product stream containing titanium dioxide particles; and introducing silicon tetrachloride into the reactor at a point down stream of the point where the titanium tetrachloride and oxygen were contacted and where at least 97% of the titanium tetrachloride has been converted to titanium dioxide or where the reaction temperature is no greater than about 1200° C., and preferably not more than about 1100° C.

A process for preparing 2-(2,4-dihydroxyphenyl)-4.6-diaryl-s-triazines in three steps starting with cyanuric chloride is described. Step 1 involves the nucleophilic (basic) displacement of one chlorine atom with a phenolic moiety. Step 2 involves a Friedel-Crafts reaction using a Lewis acid catalyst (preferably aluminum chloride) to replace the remaining two chlorine atoms with aryl groups such as xylyl. Finally, step 3 involves replacing the phenolic moiety with resorcinol using either a Lewis acid or protic acid catalyst or combinations thereof. Some additional processes only peripherally related to the three-step process outlined above are also described for the preparation of various s-triazine compounds. The s-triazines prepared are useful as UV absorbers for the stabilization of organic substrates against the adverse effects of actinic light.
