Heavy impurity transport in the presence of 3D MHD ideal perturbations

, 2022
Heavy impurity accumulation poses a problem for the operation of tokamaks featuring tungsten plasma facing components. Early termination of the plasma due to tungsten accumulation is often observed following long living 3D MHD perturbations.

Charge Transport in All‐Inorganic CuInSe2 Nanocrystal Transistors: Linking Material Design and Device Performance

Advanced Electronic Materials, EarlyView.
This work explores how colloidal CuInSe2 nanocrystals form functional field‐effect transistors when their native ligands are replaced with short inorganic species that promote charge transport. By systematically adjusting nanocrystal dimensions, surface treatments, film characteristics, and device architecture, the study maps the resulting electronic ...

A Closed‐Loop Direct Recycling Process for Prussian White From Scrap and End‐of‐Life Sodium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A closed‐loop direct recycling route for Prussian White sodium‐ion battery cathodes is demonstrated. Ice‐stripped scrap and end‐of‐life electrodes are regenerated via low‐temperature aqueous resodiation (80°C), restoring sodium content, Fe2+ redox chemistry, and structural integrity.

Long‐Range Interactions in Topological Superconducting Systems: A Mini Review

Advanced Physics Research, EarlyView.
Long‐range interacting quantum systems are surveyed in this review, with an emphasis on the long‐range topological superconductor and its variants. Long‐range interactions decaying in a power‐law manner can lead to exotic phenomena that finds no analogue in short‐range regimes.
