Semiclassical Stark Broadening Parameters of Ar VII Spectral Lines

Atoms, 2017
Using the semi-classical perturbation approach in the impact approximation, full width at half maximum and shift have been determined for eight spectral lines of Ar VII, for broadening by electron-, proton-, and He III-impacts.

Cascading Spin‐Orbitronic Terahertz Emission in Ferromagnet/Nonmagnet Bilayers

Advanced Optical Materials, EarlyView.
While the initial generation mechanism of picosecond orbital currents remains elusive, we reveal a cascading spin–orbital transport mechanism that induces optically driven terahertz emission in ferromagnet/nonmagnet heterostructures. Using a ferromagnet with strong spin–orbit coupling, we identify a thickness‐driven transition from spin‐dominated to ...

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
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,

Synergistic Stabilization of Potassium Metal Anodes Through Orange‐Peel Elimination and Robust Solid–Electrolyte Interphase Formation

Advanced Science, EarlyView.
Synergistic control of surface uniformity and solid–electrolyte interphase robustness regulates potassium deposition, suppressing dendritic growth and enabling uniform, dense potassium plating. This combined strategy promotes stable interfacial chemistry and homogeneous electric‐field distribution, leading to enhanced reversibility and long‐term ...

Al─N Co‐Doped LLZO Solid Electrolytes via One‐Step Sintering: Toward High Ionic Conductivity

Advanced Science, EarlyView.
Al–N co‐doped LLZO solid electrolytes were prepared via a one‐step sintering process, which not only simplifies fabrication process, but also diminishes Li loss during high‐temperature sintering in conventional fabrication process. The Al–N co‐doped LLZO achieves a high ionic conductivity of 2.19 × 10−3 S cm−1 because the co‐doping reduces the energy ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

Advanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses
