We introduce giant liposomes to investigate phase transformations in picoliter volumes. Precipitation of calcium carbonate in the confinement of DPPC liposomes leads to dramatic stabilization of amorphous calcium carbonate (ACC). In contrast, amorphous strontium carbonate (ASC) is a transient species, and BaCO3 precipitation leads directly to the formation of crystalline witherite.
我们引入巨型脂质体来研究皮升体积内的相变。在二棕榈酰磷脂酰胆碱(DPPC)脂质体的限制范围内碳酸钙的沉淀导致无定形碳酸钙(ACC)显著稳定。相比之下,无定形碳酸锶(ASC)是一种瞬态物质,碳酸钡沉淀直接导致形成结晶型毒重石。
