The Possibility of New Complex Magnet Materials

Advanced Materials, EarlyView.
The quest for stronger magnets enters a new era. With the developments of AI‐driven materials discovery, computational prediction of magnetic properties, and autonomous laboratories, researchers can now explore millions of untested structures. Discovery of next‐generation ultra‐powerful magnets – critical for electric vehicles, renewable energy, and ...

Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Extremely high Faraday and Kerr rotations and extraordinary optical transmission in four-layer dielectric-metal strips-dielectric-Bi:YIG planar structure

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
Faraday and Kerr effects as well as the extraordinary optical transmission in a structure that combines magneto-optical and plasmonic properties are studied. The planar structure consists of four layers, namely, dielectric layer, metal strips, once again

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 ...

Giant Kerr nonlinearity of terahertz waves mediated by stimulated phonon polaritons in a microcavity chip

Light: Science & Applications
Optical Kerr effect, in which input light intensity linearly alters the refractive index, has enabled the generation of optical solitons, supercontinuum spectra, and frequency combs, playing vital roles in the on-chip devices, fiber communications, and ...

Rotating black hole in extended Chern-Simons modified gravity

, 2009
We investigate a slowly rotating black hole in four-dimensional extended Chern-Simons modified gravity. We obtain an approximate solution that reduces to the Kerr solution when a coupling constant vanishes. The Chern-Simons correction effectively reduces

Nanoporous Microelectrodes for Neural Electrophysiology Recordings in Organotypic Culture

Advanced Materials Technologies, EarlyView.
The highly porous microelectrodes have been designed and printed on culture membranes, allowing to record electrophysiological neural activity for rodent brain slices. To keep the biocompatible nanoporous structure, the microelectrodes and insulative layer are fabricated on the bottom of culture membranes with only small connector pads added on the top.
