How do we treat zero values in a time series before running Holt Winters Multiplicative model?

I want to understand the functioning of a tool. I've been told that the tool performs multiplicative decomposition of the time series before forecasting. I've managed to decompose the series in R...

Why are graphite-acid intercalation compounds preferred for preparation of exfoliated graphite?

Graphite can be intercalated with a number of compounds including halides, alkali metals, halogens etc. Yet most of the literature points towards use of graphite-acid intercalated compounds.

How does degree of intercalation depend on graphite particle size in liquid intercalation (H2SO4-HNO3)? Can oxidation occur in very fine particles?

I wish to intercalate very fine graphite particles through a mixture of concentrated H2SO4 and HNO3. Normally, small particle size results in greater degree of intercalation. Is it possible for...
