Nanotechnology enables the design of materials with outstanding performance. A key element of nanotechnology is the ability to manipulate and control matter on the nanoscale to achieve a certain desired set of specific properties. Here, we discuss recent insight into the formation mechanisms of inorganic nanoparticles during precipitation reactions. We focus on calcium carbonate, and describe the various transient stages potentially occurring on the way from the dissolved constituent ions to finally stable macrocrystals-including solute ion clusters, dense liquid phases, amorphous intermediates, and nanoparticles. The role of polymers in nucleating, templating, stabilizing, and/or preventing these structures is outlined. As a specific example for applied nanotechnology, the properties of cement are shown to be determined by the formation and interlocking of calcium-silicate-hydrate nanoplatelets. The aggregation of these platelets into mesoscale architectures can be controlled with polymers.

“…Crystallization processes in confined environments are essential for a wide range of fields, ranging from scaling in pipelines, to biomineralization, to the construction industry [1][2][3][4][5][6][7][8][9][10][11][12]. All of these processes are characterized by a hindered ion diffusion, locally higher supersaturation, and often heterogeneous crystallization.…”

Abstract:The investigation of mineralization and demineralization processes is important for the understanding of many phenomena in daily life. Many crystalline materials are exposed to decay processes, resulting in lesions, cracks, and cavities. Historical artifacts, for example, often composed of calcium carbonate (CaCO 3 ), are damaged by exposure to acid rain or temperature cycles. Another example for lesions in a crystalline material is dental caries, which lead to the loss of dental hard tissue, mainly composed of hydroxyapatite (HAp). The filling of such cavities and lesions, to avoid further mineral loss and enable or support the remineralization, is a major effort in both areas. Nevertheless, the investigation of the filling process of these materials into the cavities is difficult due to the non-transparency and crystallinity of the concerned materials. In order to address this problem, we present a transparent, inexpensive, and reusable test system for the investigation of infiltration and crystallization processes in situ, being able to deliver datasets that could potentially be used for quantitative evaluation of the infiltration process. This was achieved using a UV-lithography-based micro-comb test system (MCTS), combined with self-assembled monolayers (SAMs) to mimic the surface tension/wettability of different materials, like marble, sandstone, or human enamel. Moreover, the potential of this test system is illustrated by infiltration of a CaCO 3 crystallization solution and a hydroxyapatite precursor (HApP) into the MCTS.

Nanotechnologie ermöglicht die Herstellung von Materialien mit hervorragenden Leistungscharakteristika. Ein Schlüsselelement der Nanotechnologie ist die Fähigkeit, Materie auf der Nanoskala zu manipulieren und zu steuern, um einen gewünschten Mix aus spezifischen Eigenschaften zu erhalten. Hier stellen wir jüngste Erkenntnisse zu den Bildungsmechanismen von anorganischen Nanopartikeln im Rahmen von Fällungsreaktionen vor. Am Beispiel von Calciumcarbonat beschreiben wir die verschiedenen Zwischenstufen, die auf dem Weg von den gelösten Ionen bis zu stabilen Makrokristallen auftreten können – einschließlich gelöster Ionencluster, flüssiger Phasen, amorpher Zustände und Nanopartikeln. Die Rolle von Polymeren bei der Nukleation, Templatierung, Stabilisierung und/oder Verhinderung dieser Strukturen wird skizziert. Als Beispiel für angewandte Nanotechnologie diskutieren wir die Eigenschaften von Zement, die durch die Bildung und das Ineinandergreifen von Calcium‐Silikat‐Hydrat‐Nanoplättchen festgelegt werden. Die Aggregation dieser Plättchen hin zu mesoskaligen Gebilden kann mithilfe von Polymeren gesteuert werden.
