Advanced Engineering Materials, EarlyView.A wood‐based magnetic and conductive material called Magwood (MW), capable of blocking almost 99.99% of electromagnetic waves (in the X‐band frequency range), is synthesized using a simple, solvent‐free process. MW is lightweight, resists water, and is flame‐retardant, making it a promising alternative for shielding electronics. The rapid proliferation

qPlus magnetic force microscopy in frequency-modulation mode with millihertz resolution
Beilstein Journal of Nanotechnology, 2012 Magnetic force microscopy (MFM) allows one to image the domain structure of ferromagnetic samples by probing the dipole forces between a magnetic probe tip and a magnetic sample. The magnetic domain structure of the sample depends on the alignment of the

Long-range magnetic dipole-dipole interaction mediated by a superconductor
Physical Review Research, 2021 Quantum computations and simulations require strong coherent coupling between qubits, which may be spatially separated. Achieving this coupling for solid-state-based spin qubits is a long-standing challenge. Here we theoretically investigate a method for

Shadows of Bonnor black dihole by chaotic lensing
, 2018 We have studied numerically the shadows of Bonnor black dihole through the technique of backward ray-tracing. The presence of magnetic dipole yields non-integrable photon motion, which affects sharply the shadow of the compact object.

Light‐Controlled Reversible Coassembly of Hybrid Functional Nanostructures
Advanced Functional Materials, EarlyView.Light‐responsive hybrid nanostructures are formed by coassembling azobenzene‐ and PAH‐functionalized nanoparticles through reversible an tunable π interactions. The system enables tunable coupling between distinct components such as gold and magnetite or carbon nanotubes, producing switchable optical and magnetic properties under light and magnetic ...
