摘要： The invention provides methods for producing hydrogen and oxygen, comprising the steps of: (i) oxidising a mediator at a working electrode to yield an oxidised mediator, and reducing protons at a counter electrode to yield hydrogen; and (ii) reducing an oxidised mediator at a working electrode to yield a mediator, and oxidising water at a counter electrode to yield oxygen, wherein the oxygen generation step is performed non-simultaneously to the hydrogen generation step, and the oxidised mediator of step (i) is used as the oxidised mediator of step (ii), or the mediator of step (ii) is used as the mediator of step (i), and the mediator has a reversible redox wave lying between the onset of the oxygen evolution reaction (OER) and the hydrogen evolution reaction (HER).

摘要： A method is disclosed of manufacturing a semiconductor structure comprising an (001) oriented zincblende structure group III-nitride layer, such as GaN. The layer is formed on a 3C-SiC layer on a silicon substrate. A nucleation layer is formed, recrystallized and then the zincblende structure group III-nitride layer is formed by MOVPE at temperature T3 in the range 750-1000° C., to a thickness of at least 0.5μ. There is also disclosed a corresponding semiconductor structure comprising a zincblende structure group III-nitride layer which, when characterized by XRD, shows that the substantial majority, or all, of the layer is formed of zincblende structure group III-nitride in preference to wurtzite structure group III-nitride.
The present invention provides methods for producing hydrogen using a mediator that is capable of reversibly donating and accepting four or more electrons. A method of the invention comprises the steps of reducing a mediator by four or more electrons to yield a reduced mediator, and oxidising a reduced mediator to yield a mediator, and reducing protons to yield hydrogen.-

摘要： The invention provides a method for preparing a compound or a product having one or more characteristics that meet or exceed a user specification, the process comprising the step of selecting a first combination of chemical inputs, optionally together with physical inputs, and supplying those inputs to a reaction space, thereby to generate a first product; analyzing one or more characteristics of the product generated; comparing the one or more characteristics against a user specification; using a genetic algorithm selecting a second combination of chemical inputs, optionally together with physical inputs, wherein the second combination differs from the first combination, and supplying those inputs to the reaction space, thereby to generate a second product; analyzing one or more characteristics of the second product generated; comparing the one or more characteristics generated against the user specification; repeating the selecting and analyzing steps for further individual combinations of chemical and/or physical inputs, to provide an array of products wherein the flow chemistry system operates continuously to provide the first, second and further products, thereby to identify one or more products meeting or exceeding the user specification.
