On the anomalous diffusion in nonisothermal plasma [PDF]

Physics of Plasmas, 2012
In nonisothermal plasmas at temperature Te≫Ti diffusion plays a decisive role at conditions of smooth inhomogeneity when the inhomogeneity size is much larger than Te/Ti times the Debye radius. When the inhomogeneity is rather abrupt and this condition is violated, then during the spreading process the Maxwellian relaxation of ion charges becomes ...

A Simple Descriptor for Solid‐State Ionic Conductors Across Chemistries

Advanced Materials, EarlyView.
Researchers develop a simple and transferable descriptor, distance contraction, for solid‐state ion migration across Li‐, Na‐, K‐, and Mg‐ion conductors and diverse anion chemistries. By capturing the maximum local contraction experienced by the migrating ion, the descriptor enables rapid materials screening and unifies diverse ion‐transport mechanisms.

A Family of Sodium Solid‐State Electrolytes Based on the NaGaxAl1‐xCl4 Solid Solution

Advanced Materials Interfaces, EarlyView.
ABSTRACT Sodium‐based metal chloride solid electrolytes are promising for sodium solid‐state batteries due to their excellent oxidation stability, which, as shown for Li halides, can coexist with high ionic conductivity. To explore cationic substitution effects, we synthesized NaGaxAl1‐xCl4 (0 ≤ x ≤ 1) via ball milling and investigated structural and ...

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

Advanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Disentangling Optical Transport Regimes in Hyperuniform Photonic Materials Via Transverse Beam Spreading

Advanced Optical Materials, EarlyView.
Light in a disordered dielectric slab spreads, confines, or is blocked depending on the transport regime. Studying the transverse spreading of a focused beam at the output face identifies diffusion, Anderson localization, and photonic bandgaps, and yields the localization length from a single slab thickness.
