Ab Initio Molecular Dynamics Simulation of Co-N-C Single-Atom Catalysts at the Electrolyte Interface for Oxygen Reduction Reaction

Nonaqueous lithium-oxygen batteries (LOBs) have significant application potential due to their extremely high theoretical energy density, but the role of the electrolyte in regulating the reaction kinetics during the oxygen reduction reaction (ORR) remains unclear. Here, we systematically investigate the ORR pathways at the electrolyte interface with Co-N-C single-atom catalysts (SACs) using ab initio molecular … Read more

Rusty PCB: Where Is the Problem?

When printed circuit board assemblies (PCBA) return with corrosion, analysts need to find the source of contamination that caused the corrosion in order to eliminate it. Contaminants can come from various sources, such as manufacturing operations, packaging, installation, and the environment. There are many methods that can be used to determine the composition of contaminants. … Read more

Analysis of Failure Causes for PCB Via Breakage (Corrosive Via Breakage)

1. Introduction The copper in the vias of a printed circuit board (PCB) is akin to the neural network (blood vessels) of the human body, interspersed within the substrate “body” to provide the basic pathways for signal transmission and current conduction. Once a via copper break occurs, it is like a nerve being severed, preventing … Read more
