The reaction products and microstructure of an 8 M NaOH-activated fly ash (AAFA) cured with microwave thermal oven curing were comparatively investigated. results show that the formation Al-rich N-A-S-H gel a flaky morphology crystalline chabazite-Na between particles favoured under curing, whilst Si-rich fibrilllar hydroxysodalite on surface dominant curing. these unique is attributed not only...

Abstract The development of a low temperature (−160 °C) NO adsorption technique is disclosed that avoids the chemical conversion probe molecule at room temperature. observed IR peaks for Cu + (NO) 2 and 2+ species can be used to quantify amount exchanged copper in broad range samples, including wash‐coated honeycomb. Calibration curves are determined loadings up 3.99 wt% with Silica‐to‐Alumina ...

Abstract A multimodal imaging study of chabazite is used to show the distribution and discriminate between different emissive deposits arising as a result detemplation process. Confocal imaging, 3D fluorescence lifetime multispectral Raman mapping are three types behaviours each characterised by spatial distributions, trends in lifetime, spectral signals, signatures. notable difference seen mor...
