    In search of a new class of stable nitroxide: synthesis and reactivity of a peri-substituted N,N-bissulfonylhydroxylamine by Patel, Bhaven, Carlisle, Julie, Bottle, Steven E., Hanson, Graeme R., Kariuki, Benson M., Male, Louise, McMurtrie, John C., Spencer, Neil, Grainger, Richard S.

    Published 2011
    “…In an approach to stabilising a bissulfonylnitroxide radical, the cyclic, peri-substituted N,N-bissulfonylhydroxylamine, 2-hydroxynaphtho[1,8-de][1,3,2]dithiazine 1,1,3,3-tetraoxide (1), has been prepared by formal nitrogen insertion into the sulfur–sulfur bond of a sulfinylsulfone, naphtho[1,8-cd][1,2]dithiole 1,1,2-trioxide. The heterocyclic ring of 1 is shown to adopt a sofa conformation by X-ray crystallography, with a pseudo-axial hydroxyl group. …”

    A multi-beam circularly polarised Fabry-Perot resonator antenna array using SIW for X-Band applications by Khajeh Mohammad Lou, Reza, Aribi, Tohid, Sedghi, Tohid, Virdee, Bal Singh

    Published 2025
    “…This paper presents a novel multi-layer beamforming antenna array based on Fabry-Perot resonator that is excited by a high performance compact 4 × 4 Butler matrix using substrate integrated waveguide SIW) technology for X-band application. The adapted ring patch antenna is fed through the aperture on a rectangular SIW cavity and forms the radiating element in the antenna array. …”

    Holocene environmental change in the Scottish Highlands: multi-proxy evidence from blanket peats by Binney, Heather Alexandra

    Published 1997
    “…This thesis seeks to investigate the Holocene environmental history of two areas of Northern Scotland with specific reference to the evidence for pine woodland density variations and tree-line dynamics. The evidence is derived from the biostratigraphy of of peat profiles sampled along altitudinal transects in the two upland areas of Gleann Einich in the Cairngorms (between c.500m OD and 930m OD) and Beinn Dearg in the Northwest Highlands (between c.270m OD and c.600m).…”

    Novel opto-electronic and plastic fibre sensors by Ioannides, Nicos

    Published 1998
    “…The middle POF is coupled to a red LED and emits light onto a flat target with the two outer fibres receiving the reflected light from the target and guiding it to two silicon PIN photodiodes. Theoretical investigations on the behaviour of the sensor are presented for ranges between 0 mm and 100 mm, and for targets with different reflectivities. …”
