Figure 3

Representative FESEM images. (a) Untreated wild grass, (b) steam exploded wild grass, (c) alkali (NaOH) treated wild grass. All images are shown at same magnification-scale bar: 200 nm. Topological changes associated with pretreatment, namely, steam explosion and alkali based treatment are clearly detectable in (b) and (c).
