Advanced Materials, EarlyView.This work investigates Ruddlesden–Popper (RP) defects in vapor‐deposited CsPbI3 thin films using electron microscopy, density functional theory, and optoelectronic measurements. The atomic positions at the planar defect are found comparable to those of a free surface, revealing their role in phase stabilization.

Rare‐Earth Ion Intercalation in Graphene via Thermal and Electrostatic Control
Advanced Materials, EarlyView.Europium ions reversibly intercalate into the van der Waals gap of bilayer graphene when heat and electrostatic gate act together, switching the stacking order and electronic response on demand. Real‐time transport, simulations, and device tests expose a hidden 2D Eu sheet and its temperature‐tuned diffusion, showing a versatile electrochemical route ...

Report of the Science Working Group: Science with a lunar optical interferometer [PDF]
Resolution is the greatest constraint in observational astronomy. The Earth's atmosphere causes on optical image to blur to about 1 arcsec or greater.

Advanced Materials, EarlyView.The coexistence of ferromagnetic and antiferromagnetic orders in van der Waals magnet above room temperature, inducing an intrinsic exchange bias and canted perpendicular magnetism is discovered. Such non‐trivial intrinsic magnetic order enables the realization of energy‐efficient and magnetic field‐free spin‐orbit torque memory devices.

Noblesse et servitude du calcul astronomique
Revue d'anthropologie des connaissances, 2009 The article deals with the mathematical practices of the Toulouse’ astronomers during 18th and 19th centuries. Computations were socially and intellectually distributed in a very precise and constant way on nearly two centuries.
