  2. The formation of carbon-carbon bonds by pinacol coupling of aldehydes and ketones requires a large negative reduction potential, often realized with a stoichiometric reducing reagent. Here, we use solvated electrons generated via a plasma-liquid process. Parametric studies with methyl-4-formylbenzoate reveal that selectivity over the competing reduction to the alcohol requires careful control over mass transport. The generality is demonstrated with benzaldehydes, benzyl ketones, and furfural. A reaction-diffusion model explains the observed kinetics, and ab initio calculations provide insight into the mechanism. This study opens the possibility of a metal-free, electrically-powered, sustainable method for reductive organic reactions.

  5. Abstract Additive methods for manufacturing materials have recently emerged, particularly for the fabrication of three‐dimensional architectures. Because of their long history in thin‐film etching and deposition, plasmas offer unique advantages for many of the materials and surface processes associated with additive manufacturing. Here, we review recent efforts that have been primarily focused on the direct writing of patterned structures and the post‐treatment of printed materials. Different configurations, materials, and applications are presented. Current challenges and a future outlook are also provided.
