Visualizing nanoparticle dynamics using AI-based method
Static image taken from video (shown below). Left: a platinum nanoparticle imaged via electron microscopy. Right: using AI-based method to remove the noise. By Patricia Waldron A team of scientists has developed a method to illuminate the dynamic behavior of nanoparticles. The work, reported in Visualizing Nanoparticle Surface Dynamics and Instabilities Enabled by Deep Denoising, in the journal Science, combines artificial intelligence with electron microscopy to render visuals of how these tiny bits of matter respond to stimuli. “The nature of changes in the particle is exceptionally diverse, including fluxional periods, manifesting as rapid changes in atomic structure, particle shape,
