Cellulose fibre images

ESEM provides opportunities for the detailed study of dynamic phenomena in real-time (crystallisation, corrosion, etc.). For example, ESEM allows visualisation of acrylic latex particles dispersed in water or the observation of a single water droplet condensing on a cellulose fibre. Images such as these may help to reveal local contact angles and also the heterogeneity of any surface treatment. The wetting properties of micro porous polymer membranes...

Fluorescent microscopic images of the fibre (Fig. 1.11) showed how the fibre was able to fix calcofluor, a fluorescent probe well-known to have high affinity with polysaccharides such as cellulose, hemicellulose and pectins. From the figure, it... 

Alemdar and Sain [86] extracted Cellulose nanofibres of wheat straw and soy hulls, by a chemi-mechanical technique. They analysed the morphology and physical properties of the nanofibres by scanning and transmission electron microscopy. The wheat straw nanofibres have diameters in the range of 10-80 nm and lengths of a few thousand nanometres, and the soy hull nanofibres have diameters in the range of 20-120 nm and shorter lengths than the wheat straw nanofibres. Fig. 1.21a and b shows the TEM pictures of the wheat straw and soy hull nanofibres. The image shows the separation of the nanofibres from the micro-sized fibres. The thermal properties of the nanofibres were studied by the TGA technique and found that the... 

Cherian et al. [119] also extracted cellulose nanofibres from pineapple leaf fibres using acid-coupled steam treatment. The strucmral and physicochemical properties of the pineapple leaf fibres were studied by environmental scanning electron microscopy (ESEM), AFM and TEM and X-ray diffi action (XRD) techniques. The acid-coupled steam explosion process resulted in the isolation of PALF nanofibres having a diameter range of 5-60 nm. Figure 1.24a and b shows the AFM and TEM images of nano fibres obtained from pineapple leaf fibres. AFM and TEM support the evidence for the isolation of individual nanofibres from PALF.
