Title
Nonclassical Crystallization of Bivalent Metal Carbonates,Used
Delivery time: 8-12 business days (International)
Since nonclassical crystallization pathways were revealed, our picture of nucleation and crystal growth became in the last year quite confusing and ramified: we are confronted with the existence of liquid phases of amorphous calcium carbonate, polymerinduced liquid precursor and, last but not least, prenucleation clusters. This contribution explores: (a) The symmetrybreaking phaseselection of calcium carbonate, which is based upon a subtle interplay of interlinked equilibria and is ultimately ascribed to the weak parity violation energy difference. (b) A morphogenetic employment of mesocrystallinity: the intercrystalline minority constituent of a mesocrystal, e.g. occluded protein or polymeric additives, experiences compressionmolding which can be employed for the preparation of nanotubes of various materials, e.g. calcium carbonate or cadmium sulfide. (c) The existence of a liquid intermediate phase during metal carbonate formation. By a diffusioncontrolled and contractfree experimental setup, unequivocally evidence for the existence of nonclassical liquid intermediates, which precede the crystalline phase of bivalent carbonates at nearneutral conditions, is provided.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
