Exotic, traditional and hybrid landscapes: The subtle history of the Iberian Peninsula maize between ‘tradition’ and ‘modernity’

PLANTS, PEOPLE, PLANET, Volume 6, Issue 5, Page 1047-1059, September 2024.
Maize is the world's second most important agricultural crop. The cereal was unknown to Europeans before the end of the 15th century, but since its arrival in Europe, it has changed agriculture, food and landscapes. Terraces where maize was cultivated in the Northwest of the Iberian Peninsula contributed to the formation of local cultures and ...

Microbubble‐encapsulated Cobalt Nitrato Complexes for Ultrasound‐triggerable Nitric Oxide Delivery

ChemMedChem, Volume 19, Issue 16, August 19, 2024.
Complexation of cobalt with nitric oxide (NO) is complex and its understanding offers applications in catalysis and biological processes. We evaluated four cobalt nitrato complexes for ultrasound‐triggered release of NO. For future therapeutic evaluation we showed for one complex tolerability in vitro and encapsulation in polymeric microbubbles ...

Structural Trends and Vibrational Analysis of N,N,N′,N′−Tetramethylmalonamide Complexes Across the Lanthanide Series

European Journal of Inorganic Chemistry, Volume 27, Issue 6, February 21, 2024.
Exploring the structural and vibrational properties of N,N,N′,N′−tetramethylmalonamide complexes across the lanthanide series may explain the lanthanide speciation and distribution ratios during liquid‐liquid separations by diamide extractants. Abstract Fundamental understanding of coordination chemistry across the lanthanide series is essential for ...

Synthesis of Bridged Tetrazoles with Promising Properties and Potential Applications by a One‐Step Finkelstein Reaction

Chemistry – A European Journal, Volume 30, Issue 1, January 2, 2024.
Several new nitramine‐ and oxa‐bridged bis‐tetrazolyl energetic materials were synthesized and fully characterized. The thermal behavior of all compounds was studied and their sensitivities towards impact (IS) and friction (FS) determined. Energetic properties, were calculated using the EXPLO5 (V6.06.01) computer code.
