Abstract: 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 0.5?. 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.

Abstract: A device is disclosed for the preparation of nebulised droplets, for inhalation. The device has: a surface acoustic wave (SAW) transmission surface; a SAW transducer adapted to generate and propagate SAWs along the SAW transmission surface; and an array of cavities opening at the SAW transmission surface for containing a liquid. In operation, SAWs propagating along the SAW transmission surface interact with the liquid in the cavities to produce nebulised droplets of the liquid. Operation of the device results in a nebulised plume of droplets of average diameter in the range 1-5 ?m.

Abstract: A biomarker detection apparatus in which a CMOS-based chip is used to generate independent detection signals from a reaction zone that receives a biological sample, where the biological sample is provided to both a test region and positive and negative control regions within the reaction zone. The independent detection signals can be processed together (i.e. as a group of input parameters for an algorithm) to identify the presence of a biomarker (or a plurality of biomarkers) in a biological sample. The use of sample-specific, independently detectable positive and negative controls facilitates improved detection accuracy.

Abstract: A CMOS-based chip having multiple sensing modalities that are able independently to detect multiple metabolites present in a sample. In particular, the chip provides multiple sensing modalities capable of performing detection within the same physical test volume, i.e. the chip can simultaneously detect a plurality of chemical reactions occurring in the test volume, where each chemical reaction yields a result that is independently detectable. The chip may comprise an optical sensor (e.g. photodiode) and a chemical sensor (e.g. pH sensor, embodied as an ISFET). With this technique, multiple metabolites may be measured in real time using a small scale point-of-care device.

Abstract: A CMOS-based chip having one or more sensing modalities that are able independently to detect multiple metabolites present in a biological sample. The multiple sensing modalities may be provided at different locations with respect to the chip, whereby the chip can simultaneously detect a plurality of metabolites by measuring behaviour of a test material in the different locations. The chip may utilise paper as a transport mechanism for the sample. The paper either conveys the sample to the different locations or itself provides discrete testing zones in which different metabolites can be independently detected. With this technique, multiple metabolites may be measured in real time using a small scale point-of-care device.

Abstract: A method of fabricating a field-effect transistor in which a native oxide layer is removed prior to etching a gate recess. The cleaning step ensures that the etch of the gate recess starts at the same time across an entire sample, such that a uniform gate recess depth and profile can be achieved across an array of field-effect transistors. This results in a highly uniform switch-off voltage for the field-effect transistors in the array.
