Performance degradation and recovery of YSZ membrane under sulphuric acid thermal decomposition [PDF]

open access: yes, 2013
The effect of sulphur dioxide (SO2) present in the cathode feed stream on the performance of a 8 mole% yttria-stabilized zirconia/platinum (8YSZ/Pt) cell was studied. SO2 concentration of 30% in oxygen (5ml/min) and helium (30ml/min) was exposed to

Evaluation of photon-counting micro-CT scanning for imaging marine organisms

open access: yesFrontiers in Marine Science
IntroductionAnatomical information is crucial in marine biology research. Traditionally, destructive techniques, such as slice imaging of the sample, are used to image the inside of the sample, which are unsuitable for valuable or rare specimens.
