ADVANCED MATERIALS & PROCESSES | SEPTEMBER 2025 9 of liquid carbon as it crystallized into graphite and then, separately, as liquid carbon crystallized into diamond. Graphite crystallized in column-like patterns that eventually elongated outwards. Diamond crystallized through compact crystallites. In materials manufacturing, understanding these pathways could improve industrial diamond synthesis, especially for applications like quantum computing where precise control over crystal structure is essential. ucdavis.edu. CHARACTERIZING TIN CATALYSTS Researchers at Tohoku University, Japan, are using machine learning to characterize tin (Sn) catalyst activity. The highly accurate simulations could help scientists quickly and simply design high-performance complex catalysts. While Sn’s utility as a catalyst is well known, its underlying structureperformance relationship is poorly understood, limiting the ability to maximize its potential. “The reason these catalysts are so important is that they can convert harmful carbon dioxide into carbon-based fuels using renewable electricity, offering a sustainable solution to energy shortages and climate change,” says scientist Hao Li. To closely examine Sn catalysts, the team used machine learning to run large-scale molecular dynamics simulations, capturing the reconstructed configurations of SnO2/SnS2. This approach used data from over 1000 experimental literature sources to identify various Sn-based catalysts. The catalysts identified by the model were run in simulations that monitored their activity at different pH levels at the reversible hydrogen electrode scale. The researchers then examined the CO2 reduction reaction to see how each catalyst performed under different conditions. The new results provide unique insight into the behavior of these catalysts. www.tohoku.ac.jp.
