Polymorphic Structures of One-Dimensional Ionic Crystals Confined in Carbon Nanotubes

چکیده
Low-dimensional materials are attracting huge interest in many research fields as their confined size and reduced dimensionality allow the possibility of manipulation and utilization of their unusual properties. The interior of a carbon nanotube is one of the most ideal places for the synthesis of low-dimensional materials. Metallic [1], ionic [2], halogen [3], and dichalcogenide [4] crystals have been successfully filled in carbon nanotubes. In such nanocrystals, specific atoms, such as those at the edges or at the surface possessing a different coordination number, are more dominant than in bulk structures and can strongly affect the physical properties of the nanocrystalline materials. Therefore, a chemical analysis of a single atom and detailed structural examination are necessary for further understanding.

Erratum: Finite particle size drives defect-mediated domain structures in strongly confined colloidal liquid crystals
When liquid crystals are confined to finite volumes, the competition between the surface anchoring imposed by the boundaries and the intrinsic orientational symmetry-breaking of these materials gives rise to a host of intriguing phenomena involving topological defect structures. For synthetic molecular mesogens, like the ones used in liquid-crystal displays, these defect structures are independ...

We have developed a two-step filling process for the nano-reaction of ionic liquid in a tip-closed SWNT, where fullerenes are inserted at the end of the host SWNT as a plug to prevent the leakage of the confined ionic liquid during heat treatment.

Over the past decade many works have focused on various aspects of the dynamics of liquids confined at the nanoscale such as e.g. water flow enhancement through carbon nanotubes (CNTs). Transport of room temperature ionic liquids (RTILs) through various nanochannels has also been explored and some conflicting findings about their translational dynamics have been reported. In this work, we focus...
متن کاملNanoscale carbon greatly enhances mobility of a highly viscous ionic liquid.
The ability to encapsulate molecules is one of the outstanding features of nanotubes. The encapsulation alters physical and chemical properties of both nanotubes and guest species. The latter normally form a separate phase, exhibiting drastically different behavior compared to the bulk. Ionic liquids (ILs) and apolar carbon nanotubes (CNTs) are disparate objects; nevertheless, their interaction...
