Syntheses, X‐ray Crystal Structures, and Raman Spectra of Self‐Assembled XeO3 Chain and Network Complexes of Polytopic sp2‐ and sp3‐Nitrogen Bases

Angewandte Chemie, EarlyView.
Supramolecular 1‐D, 2‐D, and 3‐D networks comprised of ‐(‐O═Xe(O2)‐‐)‐∞ and ‐(‐Xe(O2)O‐‐‐HO(H)‐‐)‐∞ chains coordinated to polytopic N‐base ligands were synthesized and structurally characterized by X‐ray crystallography. Their Xe‐‐‐N and Xe‐‐‐O bonds are characteristic of σ–hole bonds in which the nucleophilic Lewis base sites of the N‐ligands, H2O ...

Renormalized waves and discrete breathers in $β$-FPU chains

, 2005
We demonstrate via numerical simulation that in the \textit{strongly} nonlinear limit, the $β$-FPU system in thermal equilibrium behaves surprisingly like weakly nonlinear waves in properly renormalized normal variables. This arises because the collective effect of strongly nonlinear interactions effectively renormalizes linear dispersion frequency and

Sn‐Driven Grain Boundary Elimination for Single‐Crystalline Ni‐Rich Cathodes with Superior High‐Voltage Stability in Lithium‐Ion Batteries

Advanced Science, EarlyView.
A low‐temperature synthesis method of single‐crystalline NCA was successfully achieved by Sn doping, employing the same synthetic conditions as its polycrystalline counterparts. This synthesis was conducted at a temperature that was 150 °C lower than that required for synthesizing single‐crystalline NCA without Sn doping.

Anchored Oxygen‐Release‐Suppression Phase Stabilizing High‐Voltage Ni‐Rich Cathode Materials

Angewandte Chemie, EarlyView.
A one‐step dual‐structure strategy was proposed to synthesize LiNi0.9Co0.05Mn0.05O2 (DA‐NCM) material, which is rich in oxygen vacancies and coated with a perovskite‐type La4LiNiO8 layer stabilized by La─O anchoring provided by La2Mo2O9. This strategy effectively suppressed structural degradation and oxygen release, thereby achieving stable high ...

Resonant Akhmediev breathers

Scientific Reports
Modulation instability is a phenomenon in which a minor disturbance within a carrier wave gradually amplifies over time, leading to the formation of a series of compressed waves with higher amplitudes. In terms of frequency analysis, this process results

Degradation Pathways of Silicon‐Based Anodes in Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
Silicon‐based anodes undergo degradation through five primary pathways: (1) mechanical and structural deterioration of the active material, (2) loss of electrode integrity and electrical contact, (3) mechanical instability of the solid electrolyte interphase (SEI), characterized by repetitive fracture and deformation, (4) chemical instability of the ...

Continuous and Large‐Scale: ELEANOR, the Soft Architected Arm Inspired by the Elephant Trunk

Advanced Intelligent Systems, EarlyView.
A large‐scale, architected continuum robot inspired by the macroscopic properties of the African elephant trunk achieves adaptive elephant‐like movements and whole‐body grasping. The results demonstrate that designing from the natural system’s macroscopic properties, rather than prescribing behaviors, provides a powerful strategy for developing ...
