![]() ![]() The research team discovered a “pause key”-a small molecule called triethylamine (TEA). Many scientists have put forward some hypotheses and theories about the intermediate state in the past few years, but no direct observational evidence has been obtained. However, it remains enigmatic as regards the transition of a solution from the ionic state to the crystal state. The “pause key” in the process of crystallizationĬrystallization is ubiquitous, ranging from limestone caves to kidney stones. This method is believed to create a novel reaction system, namely “inorganic ionic polymerization”, which crosses the boundary between inorganic chemistry and polymer chemistry and presages that inorganic materials will enter human life with new structures and properties. The research team also tried to repair such inorganic materials as single crystal calcite, sea-urchin spines and teeth. The relevant finding is published in a research article titled “Crosslinking ionic oligomers as conformable precursors to calcium carbonate” in the October 17 issue of Nature. This means that inorganic materials are expected to be manufactured monolithically like plastic products, and that various complicated shapes can be produced. ![]() Amazingly, oligomers can be cross-linked like polymer materials, thereby forming continuous and bulky inorganic materials. TANG Ruikang of the Zhejiang University Department of Chemistry “intercepted” a special precursor-ionic oligomers in their endeavor to “suspend” this crystallization process. When a cup of dense saltwater is continuously heated, there will appear small crystalized particles.
