Pseudo-Finsler Radially Symmetric Spaces Symmetry (IF 2.94) Pub Date : 2024-03-18 Marianty Ionel, Miguel Ángel Javaloyes
We introduce the concept of radially symmetric pseudo-Finsler spaces, which generalize the notion of symmetric Finsler spaces, and prove that this concept is equivalent to the preservation of flag curvature by parallel transport together with reversibility. As a consequence, reversible pseudo-Finsler manifolds with constant flag curvature are radially symmetric.

Investigating Cathode Electrolyte Interphase Formation in NMC 811 Primary Particles through Advanced 4D-STEM ACOM Analysis Symmetry (IF 2.94) Pub Date : 2024-03-04 Kevyn Gallegos-Moncayo, Justine Jean, Nicolas Folastre, Arash Jamali, Arnaud Demortière
This study focuses on NMC 811 (LiNi0.8Mn0.1Co0.1O2), a promising material for high-capacity batteries, and investigates the challenges associated with its use, specifically the formation of the cathode electrolyte interphase (CEI) layer due to chemical reactions. This layer is a consequence of the position of the Lowest Unoccupied Molecular Orbital (LUMO) energy level of NMC 811 that is close to the
