    • An array of photo sensing elements and a pixel therefor comprising a photoconductor semiconductor material (31, 33) fixed to a conducting (or in some applications non-conducting) substrate (29) which can conduct photons to be detected by the pixel. On top of the photoconductor semiconductor material (31, 33) is a metal terminal (41), which provides an electrode connection to the pixel. In the case of a conducting substrate, mounted on the light receiving face on the side of the substrate (29) opposite the pixel, are metal terminals (45), to provide the other terminal connections. The light receiving face of the substrate is on the opposing side of the substrate to the pixels, which allows a higher packing density of the pixels, and other advantages. Indium bumps (43) provide a connection for signal processing. The semiconductor surfaces have a passivation layer (39).

    • A new, cost effective process for the production of ultrafine particles which is based on mechanically activated chemical reaction of a metal compound with a suitable reagent. The process involves subjecting a mixture of a metal compound and a suitable reagent to mechanical activation to increase the chemical reactivity of the reactants and/or reaction kinetics such that a chemical reaction can occur which produces a solid nano-phase substance. Concomitantly, a by-product phase is also formed. This by-product phase is removed so that the solid nano-phase substance is left behind in the form of ultrafine particles. During mechanical activation a composite structure is formed which consists of an intimate mixture of nano-sized grains of the nano-phase substance and the reaction by-product phase. The step of removing the by-product phase, following mechanical activation, may involve subjecting the composite structure to a suitable solvent which dissolves the by-product phase, while not reacting with the solid nano-phase substance. The process according to the invention may be used to form ultrafine metal powders as well as ultrafine ceramic powders. Advantages of the process include a significant degree of control over the size and size distribution of the ultrafine particles, and over the nature of interfaces created between the solid nano-phase substance and the reaction by-product phase.

    • A process for the conversion of insoluble sulphide minerals into soluble sulphate compounds and other compounds which includes subjecting a mixture of a sulphide mineral and a suitable reagent to mechanical activation with or without thermal treatment to increase the chemical reactivity of the reactants and/or reaction kinetics such that a chemical reaction will occur which produces compounds that can be more readily processed to extract a metal from the sulphide mineral. The process of the invention is based on the discovery that mechanical activation with or without thermal treatment, can induce chemical reactions between sulphide minerals and certain reactants at low temperatures which cause the chemical breakdown of the sulphide grains. Such reactions, while thermodynamically favoured, generally were previously not thought to occur at temperatures less than that required for the formation of sulphur dioxide, because of kinetic limitations. The process provides an improved process for the treatment of sulphide minerals, which is more environmentally acceptable, and was also developed with a view to providing an improved lower cost process for the treatment of refractory gold ores and concentrates, which facilitates maximum recovery of the gold.
    • 将不溶性硫化物矿物转化为可溶性硫酸盐化合物和其它化合物的方法,其包括使硫化物矿物质和合适试剂的混合物经受热处理或不进行热处理以机械活化以增加反应物的化学反应性和/或反应动力学 使得将产生化学反应,其产生可以更容易地加工以从硫化物矿物中提取金属的化合物。 本发明的方法是基于这样的发现:即使用或不用热处理的机械活化可以在低温下引起硫化物矿物与某些反应物之间的化学反应,导致硫化物颗粒的化学破坏。 由于动力学上的限制,这种反应通常以低于二氧化硫形成所需的温度而不被认为是发生在热力学上有利的。 该方法提供了一种改进的处理硫化矿物质的方法,其更环保可接受,并且还开发出来,以提供改进的较低成本的方法来处理难熔金矿和精矿,这有助于金的最大回收 。

    • A method of producing a microwave resonator comprising a cavity (50) defined, at least in part, by a generally cylindrical wall (64) having an electrically conductive inner surface and containing a generally cylindrical piece of low loss dielectric material (22), characterised by forming a generally cylindrical piece of low loss dielectric material of predetermined size and placing same in a cavity to produce a microwave resonator which operates in a particular mode at a specific frequency at a particular temperature. Microwave radiation corresponding to a further operating mode is then passed into the cavity and then the frequency corresponding to the further operating mode is searched for and measured. A further generally cylindrical piece of dielectric material is produced by scaling from the first piece of dielectric material according to the ratio between the first and second frequencies. Then, the diameter and/or height of the cavity is varied to compensate for manufacturing inaccuracies in the crystal so as to obtain an output frequency close to the desired output frequency.
