What to know about Four labs find experimental differences can undermine AI catalyst predictions

Researchers from four laboratories, led by SLAC National Accelerator Laboratory, conducted round-robin experiments to test the reproducibility of catalyst data used in AI models. The study found that small variations in experimental procedures, such as stirring methods, can lead to inconsistent data, which may undermine the reliability of AI-driven catalyst predictions.

What happened

Four labs find experimental differences can undermine AI catalyst predictions Lisa Lock Scientific Editor Robert Egan Senior Editor To turn abundant carbon dioxide into valuable fuel, we need a fast and efficient way to determine which catalysts work best…

Why it matters

AI models have the potential to help guide catalyst selection, but as with internet chatbots, AI models are only as good as the data you put into them.

Common ground

By convening four laboratories from across the country to test an experimental carbon monoxide-producing catalyst, a key first step in turning carbon dioxide into fuels, researchers at SLAC National Accelerator Laboratory have demonstrated the importance of…
