Monitoring Redox Pathways and Performance Limitations in Lithium‐Sulfur Batteries Using In Situ 7/6Li and 33S NMR Spectroscopies

Angewandte Chemie, EarlyView.
Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

Fundamental Understanding of Magnetic Reconnection via Spiral CT Scan. V. Ion Demagnetization, Electron Demagnetization, and Hall Effect

The Astrophysical Journal
For the first time, we reveal the distribution of ion demagnetization, electron demagnetization, and Hall effect around a reconnection X-line by using the spiral CT scan technique, which is a novel technique analogous to that in the hospital. This X-line

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing

Advanced Robotics Research, EarlyView.
This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Revealing the nature of the ultrafast magnetic phase transition in Ni by correlating extreme ultraviolet magneto-optic and photoemission spectroscopies

, 2018
By correlating time- and angle-resolved photoemission and time-resolved transverse- magneto- optical Kerr effect measurements, both at extreme ultraviolet wavelengths, we uncover the universal nature of the ultrafast photoinduced magnetic phase ...

Deformation of continental crust along a transform boundary, Coast Mountains, British Columbia [PDF]

, 2010
New structural, paleomagnetic, and apatite (U-Th)/He results from the continental margin inboard of the Queen Charlotte fault (~54°N) delineate patterns of brittle faulting linked to transform development since ~50 Ma.

A Self‐Healing Permanent Magnet Putty for Soft Robot Skins With Force Sensing and Functional Recovery

Advanced Robotics Research, EarlyView.
Permanent magnet putty (PMP) integrates high‐coercivity NdFeB particles with a dynamic polyborosiloxane–Ecoflex matrix, achieving rapid self‐healing (90% mechanical recovery in 10 s) and magnetic recovery within 20 min. With twice the sensitivity of commercial putties, PMP enables precise 5–30 N force detection and discrimination between pressing and ...

The demagnetization factor for randomly packed spheroidal particles

, 2019
We investigate if the demagnetization factor for a randomly packed powder of magnetic spheroidal particles depend on the shape of the spheroidal particles and what the internal variation in magnetization is within such a powder.

Tuning ultrafast demagnetization dynamics in FePdPt ternary alloy films: the role of spin–orbit coupling

Results in Physics
The influence of spin–orbit coupling (SOC) on ultrafast demagnetization dynamics is still an obscure issue. Ferromagnetic ternary alloy film containing Platinum element has the advantage that SOC strength can be regulated flexibly by varying the ...
