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

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
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 ...

Ultra‐Wideline 2D Correlations Among Low‐γ Species in Solid‐State NMR via the Progressive Saturation of a Common Proton Reservoir

Chemistry – A European Journal, EarlyView.
This study introduces PROSPECT, a 2D solid‐state NMR method that correlates MHz‐wide, low‐γ anisotropic powder patterns. PROSPECT operates by progressively depleting a shared 1H dipolar‐order reservoir via two independently stepped cross‐polarizing offsets, yielding homonuclear and heteronuclear correlations without requiring direct transfers or even ...

Innovative doped flaky FeSiCr interface synergy for developing bidisperse magnetorheological fluids with super‐performance

InfoScience, EarlyView.
An excellent comprehensive performance bidisperse magnetorheological fluid (MRFs) was developed by blending self‐synthesized micron‐sized flaky FeSiCr particles with CIPs. Through the synergistic modification of particle properties, morphology and composition, this approach overcomes the challenges of achieving an optimal balance among key performance ...

Ultrafast laser induced magnetization reversal in L10 FePt films with different chemical orders

AIP Advances, 2019
Using an ultrafast laser pulse as a substitution of continuous-wave laser to excite a magnetic film leads to high spin temperature and fast demagnetization, beneficial to the rapid and efficient photo-assisted magnetization (M) reversal.
