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.

“…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. …”

Interaction suppression technique for high-density antenna arrays for mm-wave 5G MIMO systems by Alibakhshikenari, Mohammad, Virdee, Bal Singh, Althuwayb, Ayman Abdulhadi, Falcone, Francisco, Limiti, Ernesto

“…High isolation between adjacent radiation elements was achieved by embedding a crisscrossed decoupling structure comprising slotted microstrip-lines and locating in the ground-plane under each slot a dielectric ring. The proposed periodic array behaves as artificial magnetic conductor (AMC) surfaces as incident waves in the substrate are fully reflected with a near zero degrees reflection phase. …”

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

“…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. …”

An analytical study of the role of selected metal ions in bone and joint diseases by Furst, Alexandra

“…The speciation of the titanium (III)/titanium (IV) complexes in the biological matrices was investigated with Fourier transform infra red (FTIR) spectroscopy and high field proton nuclear magnetic resonance (NMR) with a Hahn spin echo pulse sequence. The chemical nature of non-protein bound iron present in knee joint synovial fluid obtained from RA patients was also investigated by use of NMR…”

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

“…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. …”
