摘要:

限制在狭窄通道内的流体表现出与它们的降维相关联的各种相和相变。在这篇综述论文中,我们说明了交叉从准一维到更高的有效维数行为的流体吸附在不同的碳纳米管的几何形状。在单纳米管几何形状中,在有限温度下不会发生相变。相反,我们确定了一个交叉从准一维到二维行为的吸附质。在纳米管束中,在有限温度下的相变是由通道之间相互作用的横向耦合引起的。

英文摘要:

Fluids confined within narrow channels exhibit a variety of phases and phase transitions associated with their reduced dimensionality. In this review paper, we illustrate the crossover from quasi-one dimensional to higher effective dimensionality behavior of fluids adsorbed within different carbon nanotubes geometries. In the single nanotube geometry, no phase transitions can occur at finite temperature. Instead, we identify a crossover from a quasi-one dimensional to a two dimensional behavior of the adsorbate. In bundles of nanotubes, phase transitions at finite temperature arise from the transverse coupling of interactions between channels.
