Reactive Molecular Dynamics (Reactive molecular dynamics), utilizing Reactive Force Field (ReaxFF), is a simulation method capable of modeling the formation and dissociation of materials resulting from interactions between particles. It is widely used to analyze structural changes and understand reaction mechanisms across a wide range of reactions.
반응힘장을(Reactive force field, ReaxFF) 이용한 반응성 분자 동역학은 (Reactive molecular dynamics) 입자 간의 상호작용으로 인한 물질의 생성 및 분해를 모사할 수 있는 시뮬레이션 방법으로, 다양한 반응에서 물질의 구조 변화와 반응 메커니즘을 분석하기 위해 널리 사용되고 있습니다.
In contrast to computationally intensive quantum mechanical approaches, Reactive Molecular Dynamics offers a cost-effective solution by leveraging classical mechanics through ReaxFF. This enables simulations to span larger system size and timescales, facilitating comprehensive investigations into a wide array of chemical reactions and catalytic processes.
전자에 대해서 복잡한 계산을 해야 하는 양자역학적 방법과 달리, 고전역학을 기반으로 하여 반응힘장(ReaxFF)을 이용하기 때문에 계산 비용이 적게 들며 더 크고 긴 시간 범위에서의 시뮬레이션이 가능합니다. 또한 결합의 생성과 해리를 모사할 수 있기 때문에 다양한 화학반응, 촉매 반응을 모사하여 물질의 특성을 이해하고 메커니즘을 연구할 수 있습니다.
Our research group harnesses the power of Reactive Molecular Dynamics to simulate and understand physical and chemical reactions occurring in various catalytic reactions. Through this approach, we aim to unveil innovative pathways for designing highly efficient catalysts that contributes to catalyst development for sustainable energy resources.
