“…[224] Liquids with high surface tensions (e.g., metals) can therefore only enter under an applied pressure, or under oxidative conditions where the metal reacts with the oxygen or carbon to create a compound with reduced interfacial tension. [224] Early studies focused on filling nanotubes with metals, [225][226][227] metal oxides, [228][229][230][231][232] metal carbides, [226,233,234] and metal salts, [235][236][237] where these and subsequent studies have been summarized in a number of review articles. [238][239][240] Similar experiments have also been carried out using alternative nanotubes including the formation of single crystal nanowires of potassium halides in BN nanotubes, [241] PbI 2 in BN, [242] MoS 2 , [242] and WS 2 nanotubes, [243] and CsI in WS 2 nanotubes.…”

Many crystallization processes of great importance, including frost heave, biomineralization, the synthesis of nanomaterials, and scale formation, occur in small volumes rather than bulk solution. Here, the influence of confinement on crystallization processes is described, drawing together information from fields as diverse as bioinspired mineralization, templating, pharmaceuticals, colloidal crystallization, and geochemistry. Experiments are principally conducted within confining systems that offer well‐defined environments, varying from droplets in microfluidic devices, to cylindrical pores in filtration membranes, to nanoporous glasses and carbon nanotubes. Dramatic effects are observed, including a stabilization of metastable polymorphs, a depression of freezing points, and the formation of crystals with preferred orientations, modified morphologies, and even structures not seen in bulk. Confinement is also shown to influence crystallization processes over length scales ranging from the atomic to hundreds of micrometers, and to originate from a wide range of mechanisms. The development of an enhanced understanding of the influence of confinement on crystal nucleation and growth will not only provide superior insight into crystallization processes in many real‐world environments, but will also enable this phenomenon to be used to control crystallization in applications including nanomaterial synthesis, heavy metal remediation, and the prevention of weathering.

“…Ternary systems were earlier encapsulated into SWNTs, but with rather limited success, resulting in no new onedimensional crystal phases being described. 20,21 Even in the case of KCl : UCl 4 , potentially providing opportunities for compositional changes in crystal structure, those were not resolved. The electronic properties for SWNTs encapsulated by ternary compounds have also never been reported to our knowledge.…”

“…[5][6][7][8][9] In addition, halides such as UCl 4 and its mixtures with KCl, were also successfully inserted. 10 All of this early work involved the filling of multi-walled nanotubes ͑MWNTs͒. More recently, the ability to generate well-defined singlewalled nanotubes ͑SWNTs͒ has led to these tubes replacing the MWNTs in these filling experiments with mixtures such as AgCl/AgBr successfully included.…”

Atomistic computer simulation models are used to interpret the results of recent high resolution transmission electron microscopy ͑HRTEM͒ experiments which have studied the filling of carbon nanotubes by liquid KI. In the HRTEM experiments, the liquid KI fills narrow width nanotubes to form low-dimensional crystallites which display specific distortions in comparison with the idealized bulk fragments. The atomistic origin of these distortions are discussed. Molecular dynamics simulations are then used to directly model the filling of these tubes and an understanding of the filling mechanisms is developed. The dependence of the filling structure on the pore radius and morphology of the carbon nanotube is discussed. Novel crystalline structures, often incorporating specific twisting, is observed for the smaller diameter nanotubes. The physical origins of the observed filling mechanisms are discussed.
