    Abstract: The invention defines a surface of a titanium-based metal implant to be inserted into bone tissue, characterised in that it comprises substantially pure titanium oxide and has a thickness of 8-50 nm. Also, the invention defines a procedure for obtaining the surface, as well as the metal implant that exhibits it. This surface exhibits good micrometric roughness and a composition that is practically free from impurities and a thickness that is approximately three times the thickness of conventional surfaces; these characteristics provide it with very good osseointegration properties.

    Abstract: Articles made of shape memory alloys having improved fatigue performance and to methods of treating articles formed from shape memory alloy materials by pre-straining the articles (or desired portions of the articles) in a controlled manner so that the resultant articles exhibit improved fatigue performance. The shape memory articles are preferably medical devices, more preferably implantable medical devices. They are most preferably devices of nitinol shape memory alloy, most particularly that is superelastic at normal body temperature. The pre-straining method of the present invention as performed on such articles includes the controlled introduction of non-recoverable tensile strains greater than about 0.20% at the surface of a desired portion of a shape memory alloy article. Controlled pre-straining operations are performed on the shape-set nitinol metal to achieve nonrecoverable tensile strain greater than about 0.20% at or near the surface of selected regions in the nitinol metal article. The pre-straining operations result in a significant increase in fatigue life of the selectively treated regions and an overall improvement in the fatigue performance of the device.

    Abstract: A supercritical etching composition and method for etching an inorganic material of a semiconductor-based substrate are provided. The method includes providing a semiconductor-based substrate having an exposed inorganic material and exposing the substrate to the supercritical etching composition, whereby exposed inorganic material is removed from the substrate. In one embodiment, the supercritical etching composition includes a supercritical component, which is not capable of etching a particular exposed inorganic material, and a nonsupercritical etching component, which is capable of etching the particular exposed inorganic material. In another embodiment, the supercritical etching composition includes a supercritical component, which is capable of etching the particular exposed inorganic material.

    Abstract: The invention provides a reagent suitable for the dissolution of metallic gold and various methods for the application of the reagent including gold analysis, gold extraction, gold separation and the in-situ treatment of gold deposits.The reagent uses a protic solvent containing a preferably non-reducing cation source and a source of bromine optionally in combination with a strong oxidizing agent. The protic solvent is water or a lower alkyl alcohol or a mixture thereof. The cation source preferably highly dissociates in the protic solvent and suitable cation sources include dibasic ammonium phosphate, ammonium sulphate, potassium chromate, hydrochloric acid, sodium hydroxide and potassium hydroxide. Cation sources which liberate ammonium cations are preferred.The strong oxidizing agent should by highly dissociated in the solvent and is preferably selected from the group consisting of hydrogen peroxide, sodium peroxide, potassium peroxide, sodium permanganate, potassium permanganate, potassium dichromate and ferric sulphate.
