Nano-scale insights regarding coke formation in zeolite SSZ-13 subject to the methanol-to-hydrocarbons reaction
A correlation between the micro- and nano-scale coking behavior of SSZ-13 was discovered with in situ / operando spectroscopy and atom probe tomography (APT), which allows for spatial reconstruction and analysis of relations between framework elements and carbon atoms.
In situ flow pair distribution function analysis to probe the assembly–disassembly–organisation–reassembly (ADOR) mechanism of zeolite IPC-2 synthesis
A four step mechanism for the disassembly and organisation stages of the ADOR process was determined using in situ flow pair distribution function.
A multimodal analytical toolkit to resolve correlated reaction pathways: the case of nanoparticle formation in zeolites
Multimodal in situ experimental data probing a complex reaction have been integrated via a multi-level analysis involving non-negative matrix factorization and correlation analysis. This strategy can be applied generally to multimodal experiments.

Pre-zeolite framework super-MIEC anodes for high-rate lithium-ion batteries
New physical insights and a robust approach are provided to develop super-MIEC anodes for high-rate batteries, which would bridge two materials families—nanoporous framework materials and conductive oxides.
Engineering intraporous solvent environments: effects of aqueous-organic solvent mixtures on competition between zeolite-catalyzed epoxidation and H 2 O 2 decomposition pathways
A combination of kinetic, thermodynamic, and spectroscopic techniques demonstrates that increasing the water fraction within organic solvents accelerates alkene epoxidations while suppressing the undesired H 2 O 2 decomposition pathway.
Zeolite encapsulated organometallic complexes as model catalysts
Encapsulated complexes have potential as model heterogeneous catalysts for gap-phase reactions.
Zeolitic imidazolate frameworks as intrinsic light harvesting and charge separation materials for ph
