Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...

Persistent Magnetism and Tunable Doping of Monolayer Graphene via Europium Density Modulation
The modulation of europium density at the graphene/rhenium interface enables electron doping of monolayer graphene both beneath and beyond the van Hove singularity. The interfacial europium is ferromagnetic, with a transition from a mixed Eu(II)/Eu(III) valence in the dense phase to a pure Eu(II) state in the diluted phase.

Tandem Takeoff: Powering Tomorrow with Industrial‐Grade Perovskite/Silicon Solar Cells
Perovskite/silicon tandem solar cells have recently achieved certified power conversion efficiencies of 34.85%, far exceeding the Shockley‐Queisser limit for single‐junction silicon and standalone perovskite cells. This review highlights the latest advances in the design, integration, and optimization of perovskite top cells for monolithic tandem ...

Química, toxicología y nanociencia
Programa Embajadores de Conferencias en el CENIM La toxicología es un área multidisciplinar e interdisciplinar de investigación. El objetivo último de la toxicología se ubica en la escala atómica y molecular; es decir, entender el efecto tóxico de sustancias químicas en base al conocimiento de su estructura a nivel molecular; así como la relación entre
