Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
Advanced Materials, EarlyView.A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

MIMO radar techniques: two-stage constant false alarm rate detection for fast-fluctuating targets
The Journal of Engineering, 2019 Here, the authors analyse a two-step constant false alarm rate (CFAR) detection problem in distributed sensor system (e.g. statistical multiple-input multiple-output (MIMO) radar) for fast-fluctuating targets (TS-AMF-II).

Bulk and Surface Dual‐Modification for Stabilizing RuO2 Anode in 2 A cm−2 PEMWE Operation
Advanced Materials, EarlyView.The high‐current‐density stability of the RuO2‐based anode in PEMWE could be taken care of by a bulk and surface dual modification strategy developed in this work, where Cr doping modulates the Ru valence state in the bulk phase, suppressing Ru overoxidation, whereas Si modification stabilizes the reaction interface by inhibiting catalyst ...

Advanced Materials, EarlyView.Device‐level zinc batteries are energy‐limited by the mass/volume of inactive components, while lean‐electrolyte operation triggers interfacial water depletion and unstable kinetics. Here we elucidate lean‐failure mechanisms and develop a COF@PAN functional separator that regulates hydrogen‐bonding networks to manage water activity and accelerate ...

Let's get ahead with research. Simply add it to RADAR - the Research Archive for Oxford Brookes [PDF]
, 2012 A leaflet aimed at staff at Oxford Brookes who want to know how to add their research to RADAR. The first section tells you how to get started, followed by reasons why you should do this, what material and which versions should be placed on RADAR, what ...
