The complexation of NiCl2 with 2,2'-Bipyridine was followed using quasielastic neutron scattering to observe reaction progress. Water adsorption in chabazite with time resolution was observed using strain induced in the aluminosilicate framework with

Catalysed diesel particulate filter (DPF) monoliths are hierarchical porous solids, as demonstrated by mercury porosimetry. Establishing structure-transport relationships, including assessing the general accessibility of the catalyst, is challenging,

Macroscopic, highly disordered, mesoporous materials present a continuing challenge for accurate pore structure characterization. The typical macroscopic variation in local average pore space descriptors means that methods capable of delivering stati

In this work, we have systematically investigated the effect of the Al content on the number and location of bridging hydroxyls (Bronsted acid sites) and terminal hydroxyls (terminal silanol sites) in ZSM-5 zeolites with varying silica-alumina ratio

The diffusion of ammonia in commercial NH3-SCR catalyst Cu-CHA was measured and compared with H-CHA using quasielastic neutron scattering (QENS) and molecular dynamics (MD) simulations to assess the effect of counterion presence on NH3 mobility in au

Gas sorption scanning curves are increasingly used as a means to supplement the pore structural information implicit in boundary adsorption and desorption isotherms to obtain more detailed pore space descriptors for disordered solids. However, co-ope

In this work MRI and PGSE NMR have been used to directly study the advanced condensation effect during water adsorption in a macroscopically heterogeneous sol‐gel silica pellet. It has been found that capillary condensation will occur at unexpected
