    Armoring Impedes Direct Air Capture of CO2 by MgO

    Scientific Achievement: This work showed that the rate of CO2 uptake by MgO slows over time and is limited by CO2 diffusion through the reacted layer.Significance and Impact: MgO is a promising candidate material for direct air capture of CO2, but the rate of uptake and the controls on its reactivity are not known. The armoring effect shown here will need to be overcome to improve the economics of this inexpensive DAC method.DOI: 10.1021/acs.est.3c04690

    A Robust Cathode Electrolyte Interphase (CEI) has been Formed Through Surface Engineering

    Scientific Achievement: A novel approach has been demonstrated to create a conformal LiF surface layer on cathodes through ion-exchange metathesis that enables the formation of stable and uniform cathode electrolyte interphase (CEI).Significance and Impact: This work addresses the critical issues of electrolyte degradation and CEI instability by showing that ion-exchange metathesis can be used to control the structure and composition of the interface, leading to safer, more efficient, and sustainable energy storage systems.DOI: 10.1002/adfm.202302443

    Bifunctional nanoprecipitates strengthen and ductilize a medium-entropy alloy

    Scientific Achievement: Spatial confinement imposed by bifunctional nanoprecipitates enhances strength and ductility of medium-entropy alloys (MEAs) by impeding dislocation motion and modulating transformation-induced plasticity. Significance and Impact: Precipitate characteristics and alloy chemistry can be precisely tailored to activate deformation mechanisms exactly when needed to thwart the strength-ductility tradeoff.DOI: 10.1038/s41586-021-03607-y
