Graphite intercalation compound with iodine as the major intercalate [PDF]

open access: yesCarbon, 1994
Halogenated graphite CBr(x)I(y) (I less than y/x less than 10) was made by exposing graphite materials to either pure Br2 or an I2/Br2/HBr mixture to initiate the reaction, and then to iodine vapor containing a small amount of Br2/HBr/IBr to complete the intercalation reaction.

Electrochemical study of the electrodeposition and intercalation of sodium into graphite from sodium chloride as the first step of carbon nano-tubes formation [PDF]

open access: yesJournal of Mining and Metallurgy. Section B: Metallurgy, 2003
The mechanism of sodium reduction in sodium chloride melt at three different electrodes has been investigated by means of cyclic voltammetry. The definition of so-called ‘thermodynamic’ or ‘material balance’ reversibility has been introduced. It has been

Influence of Energy State of Montmorillonite Interlayer Cations on Organic Intercalation

open access: yesAdvances in Materials Science and Engineering, 2018
It is well known that the intercalation of montmorillonite (Mt) with organic cations is a fast process. During the intercalation, the interaction between the original cations and the structure layer of Mt keeps changing, and the basal spacing of Mt keeps
