Room temperature, liquid-phase AlO surface coating approach for Ni-rich layered oxide cathode material.

A room temperature, atomic-layer-deposition-like coating strategy for NCM811 (80% Ni) is reported. Trimethylaluminum is shown to readily react with adsorbed moisture, leading both to Al2O3 surface layer formation on NCM811 and to trace H2O removal in a single treatment step. Even more importantly, the cycling performance of pouch cells at 45 °C is greatly improved.

Morphologic changes of the uteroplacental unit in preeclampsia-like syndrome in rats.

Objective: Chronic administration of the nitric oxide synthase inhibitor NG-nitro-L-arginine methylester (L-NAME) induces a preeclampsia-like syndrome in rats. This animal study aims to determine whether L-NAME-induced preeclampsia-like syndrome is also associated with morphologic changes in the uteroplacental unit.

Methods: Mating was induced in 20 adult Sprague-Dawley rats.
