Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx
Advanced Materials, EarlyView.We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Signatures of Edge States in Antiferromagnetic Van der Waals Josephson Junctions
Advanced Materials, EarlyView.ABSTRACT The combination of superconductivity and magnetic textures leads to unconventional superconducting phenomena, including new correlated and topological phases. Van der Waals (vdW) materials emerge as a versatile platform for exploring the interplay between these two competing orders.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Nem arrancada, nem outorgada: agência, estrutura e os porquês da Lei do Ventre Livre
AlmanackResumo O artigo procura avaliar em que medida a edição da Lei do Ventre Livre, de 28 de setembro de 1871, constituiu um reflexo da libertação de escravos para combater na Guerra do Paraguai (1864-1870). Buscou-se contrastar, por um lado, a historiografia

A Soft, Flexible Implant for Wireless Photothermal–Pyroelectric Neurostimulation
Advanced Science, EarlyView.A replication strategy is used to enlarge the exposed surface area of barium titanate within flexible films with embedded carbon nanotubes, enabling efficient photothermal‐pyroelectric stimulation. Polar crystalline nanosheets show superior performance in guiding neural progenitor cells toward neuronal differentiation.

Isolable C‐Phosphonio‐Boratavinyl Anion
Angewandte Chemie, EarlyView.A persistent C‐phosphonio boratavinyl anion was successfully synthesized. This boron‐containing vinyl lithium, featuring a vinyl carbon with an excessively high negative charge, exhibits remarkable nucleophilic and basic character, which was demonstrated by the result of a rapid reaction with H2 at RT.
