Type I Graphite

Graphite is known to be intercalated by both electron donors and acceptors and to a large extent the driving force for intercalation is electronic in nature. Thus depending on the guest species, positively charged carbon layers or negatively charged carbon layers may be obtained. Graphite intercalation compounds usually exhibit a high degree of ordering and are unique among layered host materials in that the intercalation occurs such that, depending on the extent of guest species incorporation, it is possible to observe the staging phenomenon (Figure 2). The staging phenomenon is defined by a periodic arrangement of n graphite layers (where n is the stage index) between sequential intercalant layers. Well staged graphite intercalated materials can be prepared up to n & 10. Strong interatomic intercalant-intercalant binding relative to the intercalant-graphite binding favours a close-packed in-plane intercalant arrangement and is the driving force for the staging phenomenon. Graphite intercalation compounds (GICs) have found use as catalysts, electric conductors, recording materials (in inks and coloured leads) and as lubricants and low friction coatings.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
