Juan de Betanzos et Francisco de Villacastín : deux conquérants dans la tourmente des guerres du Pérou (années 1530-1550)

E-Spania, 2016
Juan de Betanzos (1519-1576) et Francisco de Villacastín ( ?-1549 ?) ont en commun de faire partie de la deuxième génération de conquérants du Pérou, d’avoir épousé des princesses incas, de maîtriser le quechua et d’avoir mené des recherches sur le passé

18F‐Radiopharmaceutical Diversification Enabled by Deaminative Cross‐Electrophile Couplings

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
A general Ni‐mediated (C)sp2–(C)sp3 cross‐coupling expedites access to 18F‐radiopharmaceuticals, essential for positron emission tomography imaging and drug discovery. This late‐stage diversification approach was implemented across three user‐friendly automated protocols affording 18F‐radiotracers in sufficient quantities for imaging.

Perspectives on Social and Justice Issues in Climate Policy – Comparing the Just Transitions, Sustainable Welfare and Eco‐Social Policy Literatures

WIREs Climate Change, Volume 17, Issue 1, January/February 2026.
Mapping the Just Transitions, Sustainable Welfare and Eco‐Social Policy Literatures along the axes of capitalism/growth approaches and global justice demonstrates that there is a large gap in research at the intersection of overcoming‐capitalism/post‐growth growth approaches and global justice/decolonisation analysis.

Ball‐Milling Assisted Iron‐Catalyzed Difluoromethylation Toward the Synthesis of Valuable Oxindoles

ChemSusChem, Volume 18, Issue 24, December 13, 2025.
An iron‐catalyzed difluoroalkylation of acrylamides under ball‐milling conditions affords oxindoles in up to 85% yield. Analytical studies reveal that the apparent piezoelectric activity originates from iron leaching caused by milling assembly abrasion during the reaction process. The iron‐catalyzed process proves to be efficient with a broad substrate

Exploiting Sodium Ascorbate as an Underutilized and Sustainable Sacrificial Reductant for Net Reductive Pinacol Coupling Reactions via Mechanophotocatalysis

Helvetica Chimica Acta, Volume 108, Issue 12, December 2025.
Sodium ascorbate is a safe and sustainable electron donor, yet its use in solution‐state photocatalysis reactions is often limited by its poor solubility in organic solvents. In this study, typical electron donors used for net reductive pinacol coupling reactions, such as DIPEA and the Hantzsch ester, are replaced with the more benign sodium ascorbate,
