Accelerating the Electrochemical Formation of the δ Phase in Manganese‐Rich Rocksalt Cathodes

Advanced Materials, Volume 37, Issue 6, February 12, 2025.
A method of electrochemical pulsing which forms a spinel‐like δ phase in Mn‐rich disordered rocksalt materials with Li‐excess (DRX) (DRX) cathode materials is demonstrated. This concept is extended to large single‐crystalline particles, greatly improving the cycling stability.

Mechanical Ventilator Settings Estimation From an AI Model

Applied AI Letters, Volume 6, Issue 1, February 2025.
ABSTRACT Mechanical ventilation (MV) is used in subjects with respiratory problems for assistance in breathing. Various MV settings are adjusted at the clinician's discretion based on the patient's respiratory condition. In this study, an AI (artificial intelligence) model using artificial neural networks (ANNs) along with Bayesian Optimization (BO ...
