The Graphene Revolution Arrives in India The
Graphene is an artificial material with extraordinary properties. It is a single layer of graphite. Graphene has a two-dimensional structure, but graphite has a three-dimensional crystalline oneThe majority of natural graphite powders are currently mined and produced in China and India, which hold 66% and 14% share of total world production, whereas the production of natural graphite powders in Europe is less than 1%. 12 Synthetic graphite, on the other hand, is produced using fossil-based carbon resources as raw Establishment of green graphite industry: Graphite from biomass

The success story of graphite as a lithium-ion anode material
2.2 The structural changes upon intercalation via ‘staging’ The intercalation of secondary species like ions or molecules (generally referred to as intercalants) into the graphite host structure reveals a characteristic concentration-dependent feature, the so-called staging mechanism, as developed for the first time by Rüdorff and Hofmann in 1938. 45,46 The process of dyeing of cotton with indigo essentially consists of alkaline reduction of indigo into a water soluble form known as leuco indigo, dyeing by multiple dips and air oxidation to convert leuco indigo to its water insoluble form. The reduction/oxidation process is shown in Figure 3.5. Figure 3.5.Indigo dye and reduction techniques ScienceDirect
