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.

This invention is to provide a method for producing a modified water absorbent resin excelling in water absorbing properties. This invention relates to a method for producing a modified water absorbent resin, which comprises a) mixing a water absorbent resin and a water-soluble radical polymerization initiator or a heat-degradable radical polymerization initiator without addition of an ethylenically unsaturated monomer and b) irradiating the resultant mixture with active energy rays. The method is particularly capable of exalting the absorbency against pressure and the saline flow conductivity.

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 hydrogen halide acid and / or an oxyacid, a chloride containing compound, and an oxidizing agent. The etching solution can be used at ambient temperature without damaging the metal elements on the substrate surface. 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.

There is disclosed a plasma reactor for processing a semiconductor workpiece such as a wafer, including a chamber having an overhead ceiling with a three-dimensional shape such as a hemisphere or dome. The reactor further includes an inductive antenna over the ceiling which may be conformal or nonconformal in shape with the ceiling. The ceiling may be a semiconductor material so that it can function as both a window for the inductive field of the antenna as well as an electrode which can be grounded, or to which RF power may be applied or which may be allowed to float electrically. The reactor includes various features which allow the radial distribution of the plasma ion density across the wafer surface to be adjusted to an optimum distribution for processing uniformity across the wafer surface.
