Room‐Temperature Multiferroic Liquids: Ferroelectric and Ferromagnetic Order in a Hybrid Nanoparticle–Liquid Crystal System

Advanced Materials, EarlyView.
A hybrid fluid combining ferrimagnetic nanoplatelets and a ferroelectric nematic displays coexisting magnetization and polarisation at room temperature. This self‐assembled multiferroic shows strong magnetoelectric effect and nonlinear optical response, offering a soft, reconfigurable platform for next‐generation sensing, actuation, and photonic ...

3D Acoustic Imaging Hitting the Diffraction Limit via Fully Parameter‐Optimized Meta‐Lens and Frequency‐Domain Reconstruction

Advanced Materials, EarlyView.
This article employs a binary genetic algorithm to design an ultra‐fine ultrasonic meta‐lens, achieving lateral super‐resolution imaging in the far field (>20λ₀). Building on this, longitudinal resolution is effectively restored through frequency domain reconstruction.

CI. On Mr. Liston's, or the Euharmonic Scale of Musical Intervals, extended according to his tuning process, from 59 to 612 notes in the Octave; showing thus, a division of the Octave into 612 equal parts, or as nearly so, throughout, as experiments in harmonics, or the most refined musical performances, seem to require [PDF]
