How Surface Reconstruction Drives Heterogeneous Bulk Delithiation in Single-Crystalline Ni-Rich Layered Oxide Cathodes. [PDF]

Small Sci
Through multi‐rate operando X‐ray diffraction and soft X‐ray absorption spectroscopy, we demonstrate how surface‐level changes in aged single‐crystalline Ni‐rich LiNixMnyCo1−x−yO2 particles can directly affect bulk Li‐ion diffusion. The effect of this phenomenon on the electrochemical performance is also quantified using single‐layer pouch cells under ...

Coalition cascades: The politics of tipping points in clean energy transitions

Policy Studies Journal, Volume 51, Issue 4, Page 715-739, November 2023., 2023
Abstract Policy change often involves multiple policy subsystems, as in the case of clean energy transitions. We argue that trans‐subsystem policy feedback is a central dynamic in policy change across subsystems. Policy in one subsystem creates benefits/costs and/or learning effects that mobilize actors for policy change in another subsystem, resulting

The Role of Cobalt Clusters (Con, n = 1–5) Supported on Defective γ–Graphyne for Efficient Hydrogen Adsorption: A First Principles Study

Advanced Theory and Simulations, Volume 5, Issue 11, November 2022., 2022
The modification of γ‐graphyne monolayers shows to be a suitable support for small Co5 clusters. The retention capacity of H2 molecules increases as the size of the cobalt cluster increases. The large systems exhibit adequate adsorption energy values for reversible storage.
