Engineering Microbial Particles for Next‐Generation Biomedical Platforms
Microbe‐derived particles (MDPs), which include extracellular vesicles, outer membrane vesicles, inclusion bodies, polysaccharide particles, and virus‐like particles, represent a rapidly expanding category of bioinspired nanomaterials. With their natural origin, intrinsic biocompatibility, and highly programmable functionality, MDPs serve as a ...

Multi-Target Wireless Localization of Miniaturized Magneto-Oscillatory Trackers in Soft Biological Tissues. [PDF]
Miniaturized, frequency‐encoded magneto–oscillatory trackers enable wireless localization of multiple targets without prior knowledge of their positions or orientations. The method achieves accurate localization over clinically relevant distances and measures local viscoelasticity via the oscillatory responses.

Magnetomechanical neuromodulation using magnetic nanodiscs enables remote activation of neurons. In a hemiparkinsonian mouse model, alternating magnetic fields actuate the nanodiscs to generate torque that opens mechanosensitive ion channels within the subthalamic nucleus, thereby modulating basal ganglia motor circuitry.

Structure design, analysis, and optimization of 12-pole radial magnetic bearing
Active magnetic bearings (AMBs) are widely used in high-speed turbines, precision machining, and energy storage systems due to their non-contact operation, high rotational speeds, and low maintenance.

Performance of multi-stage axial-flux machines with MMEs
This study covers the investigation into the reduction of rare-earth magnets in a permanent magnet (PM) machine via the use of multiple rotors to enable a PM generator to be comprised of mixed magnetic elements, hereafter referred to as MME, by ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

A permanent MRI magnet for magic angle imaging having its field parallel to the poles [PDF]
A novel design of open permanent magnet is presented, in which the magnetic field is oriented parallel to the planes of its poles. The paper describes the methods whereby such a magnet can be designed with a field homogeneity suitable for Magnetic ...

New Insights from Revisiting the Rotation Period of the Strongly Magnetic O Star, NGC 1624-2
NGC 1624-2 hosts the strongest surface magnetic field found on an O star thus far. When applied across several epochs of observations, the star’s currently accepted rotation period (157.99 days) does not coherently characterize the variations of spectral
