The existence and properties of gases adsorbed within interstitial channels of nanotube bundles

TL;DR

This paper investigates the properties of gases adsorbed in the interstitial channels of nanotube bundles, clarifying previous conflicting results and predictions about bundle dilation due to adsorption.

Contribution

It provides a detailed analysis linking prior experimental and theoretical findings, specifically addressing the prediction of bundle dilation upon gas adsorption.

Findings

Confirmed the occurrence of gas adsorption in interstitial channels

Clarified the relationship between adsorption and bundle dilation

Reconciled differing results from recent studies

Abstract

We analyze the relationship between our group's results and those of three recent papers about gases in interstitial channels within nanotube bundles. In particular, we explain the relation between our prediction about bundle dilation upon interstitial adsorption (questioned in some way in these works) and their results.
