Building upon the depth and breadth of Harold Winters's work, this paper pays tribute to his pioneering contribution in the field of plasma etching of metals, and how that knowledge base helps guide the fundamental research in these areas. The fundamental understanding of the plasma–surface interactions during metal etch is key to achieve desirable etch efficacy and selectivity at the atomic scale. This paper presents a generalized methodology, combining thermodynamic assessment and kinetic verification of surface reactions, using copper, magnetic metals, and noble metals as examples, in an effort to demonstrate the applicability of this strategy in tailoring plasma–surface interactions at the atomic scale for a wide range of materials.
Thermally stable metal oxide additives within CaO-based sorbents mitigate particulate agglomeration during carbonation–regeneration cycling leading to significant increases in stability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
