Researchers at at Pacific Northwest National Laboratory, the University of Washington, Zhejiang University and Xiamen University, led by the group of Jim De Yoreo, used Hummingbird Scientific’s in-situ TEM dual-flow mixing liquid cell to study amorphous to crystalline transformations of calcium carbonate. They studied this transformation with multiple additives in solution and showed that certain specific additives uniquely cause a shape-preserving amorphous to crystalline transformation. Their research was published in PNAS.
