    摘要： A process for producing a lithium-manganese-rich layered oxide cathode material or a lithium-manganese-rich layered oxide cathode material precursor includes co-precipitating a dissolved Li compound and a dissolved Mn salt selected from the group consisting of Mn(CH3COO)2, Mn(NO3)2, MnSO4, and mixtures thereof, from an aqueous solution, in the presence of a precipitator which reacts at least with the dissolved Mn salt to form a carbonate, thereby providing a precipitate which includes MnCO3 and a lithium compound as a lithium-manganese-rich layered oxide cathode material precursor. The invention extends to a lithium-manganese-rich layered oxide cathode material or a lithium-manganese-rich layered oxide cathode material precursor, to an electrochemical cell, and to methods of making and operating an electrochemical cell.

    摘要： This invention relates to a method of and system for facilitating detection of a particular predetermined gas in a scene under observation. The gas in the scene is typically associated with a gas leak in equipment. To this end, the system comprises an infrared camera arrangement; a strobing illuminator device having a strobing frequency matched to a frame rate of the camera; and a processing arrangement. The processing arrangement is configured to store a prior frame obtained via the infrared camera arrangement; and compare a current frame with the stored prior frame and generate an output signal in response to said comparison. The system also comprises a display device configured to display an output image based at least on the output signal generated by the processing arrangement so as to facilitate detection of the particular predetermined gas, in use.

    摘要： This invention related to a method of and system for detecting a threat, particularly a threat to a vehicle associated with an explosive blast and/or detonations. The method typically comprises receiving electromagnetic signals, or data indicative thereof, via a suitable electromagnetic detector arrangement from a target area adjacent the vehicle, as well as receiving optical signals, or data indicative thereof, via a suitable optical sensor arrangement also from a target area adjacent the vehicle. The method then comprises generating a threat detect output in response to receiving an optical signal indicative of a threat subsequent to receiving an electromagnetic signal indicative of a threat. The system typically implements the method as described. The invention also extends to a vehicle comprising a system in accordance with the invention.

    摘要： The invention relates to optical communication methods and systems. In particular, the invention relates to an optical communication method and system which is configured to create a multiplexed beam from an incident beam, wherein the multiplexed beam comprises a predetermined number of spatial modes simultaneously generated and multiplexed together in a fashion that is independent of wavelength. The spatial modes have two degrees of spatial freedom. The multiplexed beam is de-multiplexed downstream from multiplexing thereof in the communication system in a simultaneous fashion independent of wavelength to yield the predetermined number of spatial mode. The modes are used in optical communication as channels or as bits in a bit (de) encoding scheme.

    摘要： A process for the treatment of contaminated water (10) includes contacting the contaminated water with cryptocrystalline magnesite (14) thereby to remove one or more contaminants from the water. The invention extends to powdered cryptocrystalline magnesite with a particle size such that the powdered or particulate cryptocrystalline magnesite is able to pass through a 125 μm particle size sieve for use in the treatment of water.

    摘要： The invention provides a method of diagnosing tuberculosis by using a novel antibody biomarker capturing vehicle, activating a screen-printed electrode using chemical and mechanical polishing, and immobilising mycolic acid antigen biomarkers on the activated electrode. The novel antibody biomarker capturing vehicle is produced by introducing isolated mycolic acid antigens of tuberculous mycobacterial origin onto an outer surface of a nanoparticle such that the mycolic acid antigens are presented as antibody biomarker capturing agents. The solvent resistant screen-printed electrode is activated by both chemically and mechanically polishing the electrode. The mycolic acid antigens are immobilised on the activated electrode by incubating the activated electrode with a mycolic acid-dimethylformamide solution to allow mycolic acid antigens to adsorb onto the activated electrode.

    摘要： A method of deriving a conclusion of the condition of slurry flow in a non-vertical conduit includes artificially generating a first locally heated spot on an interior surface of the conduit at the invert of the conduit and artificially generating a second locally heated spot on the interior surface of the conduit at a location angularly spaced from the first heated spot at an angular spacing of at least 90°. The temperatures of the heated spots are measured, obtaining first and second temperature values T1, T2. Electronically generated signals carrying the values T1, T2 are communicated to an electronic computing device. The computing device automatically calculates a first temperature difference T1 minus T2 and automatically derives a conclusion of the condition of slurry flow prevailing in the conduit based on the relationship between the value of the first temperature difference and a first reference parameter.
