Reporting in Nature, researchers from Zhejiang University and Xiamen University have demonstrated the growth of continuous monolith structure in calcium carbonate by cross-linking ionic oligomers using Hummingbird Liquid cell TEM holder. The method, which the authors refer to as non-classical crystallization, can be used to synthesize large quantities of inorganic oligomers, similar to what is currently achieved in polymeric materials by cross-linking monomers of oligomers. Additionally, the cross-linked oligomeric precursors can be systematically moulded into different shapes allowing engineering of single-crystalline materials including additive manufacturing.
