It is located between the … WebA grain boundary is a planar defect that occurs where two such crystallites meet—the same crystal structure and chemical composition exists on each side but the orientation differs. If a common origin is assumed, the transformation between the two is a pure rotation, which is known as the misorientation.

WebOct 13, 2024 · Highly active and stable catalysts are very crucial for boosting the oxygen evolution reaction (OER) and converting water into clean fuel. Here, we adopt the laser ablation in liquid technique to produce Ru nanoparticles (NPs) enriched with grain boundaries (GBs). The as-prepared Ru NPs were then applied as an OER catalyst, … WebSmall angle grain boundaries exhibit less atomic misfit. The top diagram illustrates this behavior, the photograph is of grain boundaries in iron magnified 500 x.
