WebFeb 22, 2024 · A more negative value of Δ G ∘ means greater product stability. This follows from the relationship (2) Δ G ∘ = − R T log K where K is the equilibrium constant for the reaction at that temperature. An increased value of K implies an increased amount of products relative to reagents. WebApr 10, 2024 · In this work, we propose entropy-targeted active learning (ET-AL) as a systematic approach to detecting and reducing materials data bias. We focus on the structure–stability bias in density functional theory (DFT)-generated databases as a use case for demonstrating the approach.
