Bruxas e princesas : Sobre rivalidade femenina e a construção da imagem da boa esposa [PDF]

open access: yes, 2012
En el mito de Psique, narrado por Apuleyo en El Asno de Oro, encontramos el origen de diversos motivos narrativos, presentes en los cuentos de hadas. Estas historias tienen personajes que pasan por una especie de rito de iniciación y deben demostrar que ...

Magnetic and Structural Response Tuned by Coexisting Mn Concentration‐Dependent Phases in MnBi2Te4 Thin Film Grown on GaAs(001) by Molecular Beam Epitaxy

open access: yesAdvanced Functional Materials, EarlyView.
The study explores structural and magnetic properties of one of the most recent topological quantum materials (MnBi2Te4). The Mn‐poor structure leads to stacking faults (quintuple layer ‐ QL of Bi2Te3 formation instead of a septuple layer ‐ SL of MnBi2Te4), resulting in a coexistence between weak antiferromagnetism and ferromagnetism.

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

open access: yesAdvanced Materials, EarlyView.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

THz‐Driven Coherent Phonon Fingerprints of Hidden Symmetry Breaking in 2D Layered Hybrid Perovskites

open access: yesAdvanced Materials, EarlyView.
Intense THz pulses are employed to drive coherent phonons in 2D Ruddlesden‐Popper hybrid metal‐halide perovskites (HOIPs) from the (PEA)2(MA)n‐1PbnI3n+1 family, revealing mode‐selective spectroscopic signatures of inversion symmetry breaking in those nominally centrosymmetric materials. These findings provide a handle to decode nonlinear phonon driving

Shapeshifting Nanocatalyst for CO2 Conversion

open access: yesAdvanced Materials, EarlyView.
A multi‐modal in situ characterization of Ag‐Cu nanoparticles during CO2 photoreduction sheds light on dynamic transformations occurring during reaction. The Cu(core)‐Ag(shell) nanoparticles present the Ag replacement by Cu atoms. Ag is trapped at the subsurface forming a Ag‐Cu‐O phase, and the nanoparticle spreads over the substrate.
