Kinetics of ion transport through supramolecular channels in single crystals.
Single-crystal to single-crystal transformations are possible by ion-exchange and transport reactions through supramolecular channels that are composed of crown ether molecules and use trihalide ions as scaffolds. Kinetic measurements of ion transport at different temperatures provide activation energy data and show that a very fast exchange of K(+) ions with Na(+) ions occurs.
متن کاملControlling and measuring quantum transport of heat in trapped-ion crystals.
Measuring heat flow through nanoscale devices poses formidable practical difficulties as there is no "ampere meter" for heat. We propose to overcome this problem in a chain of trapped ions, where laser cooling the chain edges to different temperatures induces a heat current of local vibrations (vibrons). We show how to efficiently control and measure this current, including fluctuations, by cou...
متن کاملIon transport through biological channels
The transport of ions across single-molecule protein nanochannels is important both in the biological context and in proposed nanotechnological applications. Here we discuss these systems from the perspective of non-equilibrium physics, and in particular, whether the concepts underlying the physics of diffusive and electrokinetic transport can be employed to predict and understand these systems...
متن کاملCharge transport through one-dimensional Moiré crystals
Moiré superlattices were generated in two-dimensional (2D) van der Waals heterostructures and have revealed intriguing electronic structures. The appearance of mini-Dirac cones within the conduction and valence bands of graphene is one of the most striking among the new quantum features. A Moiré superstructure emerges when at least two periodic sub-structures superimpose. 2D Moiré patterns have...
متن کاملDisorder effects on heat transport properties of orientationally disordered crystals
The thermal conductivity T of the orientational glass state of 1,2-difluoro-1,1,2,2-tetrachloroethane CFCl2-CFCl2, Freon 112 and cyanocyclohexane C6H11CN has been measured under equilibrium pressure within the temperature range 2–100 K. The results show that the soft-potential model is able to account for low-temperature data and, indeed, quantitative agreement of all data considered is found w...
