Turbulent 3D MHD dynamo model in spherical shells: regular oscillations of the dipolar field [PDF]
, 2010 We report the results of three-dimensional numerical simulations of convection-driven dynamos in relatively thin rotating spherical shells that show a transition from an strong non-oscillatory dipolar magnetic field to a weaker regularly oscillating ...

Controlling the Guanidinium Cation Rotation by Cation–π Interactions
Angewandte Chemie International Edition, EarlyView.A lanthanide π‐container has been employed to trap a guanidinium cation inside the aromatic cavity by cation–π interactions. X‐ray crystallography and solid‐state nuclear magnetic resonance (NMR) spectroscopy at fast magic‐angle spinning (MAS) frequencies have been utilized to probe the underlying host–guest interactions.

Angewandte Chemie International Edition, EarlyView.An improved low‐temperature synthesis enables the first comprehensive structural and spectroscopic characterisation of neutral hexacyanotrimethylenecyclopropane (CN6CP). Combined IR/Raman, UV–Vis and ssNMR analyses reveal a deeper understanding of its oxidation‐state‐dependent charge redistribution, σ‐aromaticity of the cyclopropane core, and redox ...

Radial differential rotation leading to dipole collapse in pre-main-sequence stars
Astronomy & AstrophysicsContext. Despite significant progress in the observational characterization of stellar magnetic fields, the physical processes that govern their intensity and topology, which could certainly result from their formation history, remain poorly understood ...

Theoretical and Experimental Investigations in MEMS-Based Force-Detected NMR [PDF]
, 2005 This thesis describes a method of mechanically detecting magnetic resonance. The detector consists of a ferromagnet harmonically bound to a mechanical resonator and measures a magnetic force of interaction with a nearby sample via dipole-dipole coupling.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review
Advanced Physics Research, EarlyView.Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.

Archaeological Prospection, EarlyView.ABSTRACT This paper presents the results of an integrated archaeological and geophysical investigation conducted between 2018 and 2024 at the newly discovered Picenian and Roman necropolis of Contrada Nevola (Corinaldo, Marche, Central Italy), identified in the framework of development‐led archaeology. The research strategy combined aerial photography,

Dipolar interaction effects in core–shell magnetic nanoparticles
Nano ExpressDipolar interaction between magnetic nanoparticles (MNPs) affects their magnetization properties, and the effect is particularly significant for multi-core MNPs and high-concentration MNP samples.
