Mössbauer Spectroscopy in Heterogeneous Catalysis
, 2007 International audienceMössbauer spectroscopy dates back to 1958 and for characterization of a solid catalyst was first used in 1971; the technique achieved a high point in the 1980s and has been applied only modestly for catalyst characterization since ...

Mössbauer spectroscopy in astrobiology
, 2015 First paragraph: Astrobiology is the study of the origin, evolution and distribution of life in the universe. As such, the field begins very much on Earth before venturing out to search for life in space.

Dual‐Site Catalysis in Electrocatalytic C–N Coupling: Challenges and Design Principles
ChemElectroChem, Volume 13, Issue 11, 3 June 2026.This review examines dual‐site catalysis in electrocatalytic C─N coupling through four recurring challenges: energetic barriers, kinetic mismatch, selectivity loss, and systemic constraints. It highlights how rationally designed dual‐site catalysts cooperatively lower reaction barriers, synchronize intermediate generation, suppress competing pathways ...

Delamination of Vermiculite into Ultrahigh‐Aspect‐Ratio Nanosheets
Zeitschrift für anorganische und allgemeine Chemie, Volume 652, Issue 9, 3 June 2026.Efficient ion exchange allows for thermodynamically driven delamination of vermiculite into high‐aspect ratio nanosheets. The applicability of sustainable materials in the packaging industry is currently limited by the poor gas barrier performance of most biodegradable polymers.

Mössbauer and heat capacity studies of ErZnSn2
Nukleonika, 2017 Heat capacity results obtained for the intermetallic compound ErZnSn2 were re-analysed to also consider, apart from the classical Debye model, the anharmonicity of the crystal lattice and the proper set of Einstein modes.
