Synthesis of zinc ferrite nanopowders in an RF thermal plasma [PDF]
, 2001 Nanosized zinc ferrite spinel powders of various compositions were produced in an RF thermal plasma from oxide mixtures and from co-precipitated hydroxides. The products were characterised for bulk chemical (ICP-AES), and phase composition (XRD).

Nomenclature of the hydrotalcite supergroup: Natural layered double hydroxides [PDF]
, 2012 Layered double hydroxide (LDH) compounds are characterized by structures in which layers with a brucite-like structure carry a net positive charge, usually due to the partial substitution of trivalent octahedrally coordinated cations for divalent cations,

Advanced Functional Materials, EarlyView.This study demonstrates that pulsed potential electrolysis significantly improves CO2 reduction performance on copper‐nitrogen doped carbon electrodes. The formation of cationic copper sites and metallic clusters as a function of applied intermittent potential leads to notable selectivity changes compared to potentiostatic reduction.
