Application
用于分区色谱的高纯度纤维素粉末。
纤维素可用于通过X射线衍射（XRD）图和固态13C核磁共振光谱测定结晶度指数。
General description
纤维素，由通过β-1，4键连接的葡萄糖单元组成的均聚物。它们通过分子间和分子内氢键以及范德华力牢固地连接，从而形成微纤维，它们共同形成纤维。它们排列在相邻葡聚糖链的平行还原端中。纤维素在TLC中广泛用作吸附剂。

In anaerobic environments rich in decaying plant material, the decomposition of cellulose is brought about by complex communities of interacting microorganisms. Because the substrate, cellulose, is insoluble, bacterial and fungal degradation occurs exocellularly, either in association with the outer cell

Nanocrystalline cellulose (NCC), a rod-shaped nanoscale material with exceptional strength and physicochemical properties, can be prepared from inexpensive renewable biomass. Besides its potential use as a reinforcing agent for industrial biocomposites, pristine NCC exhibits low toxicity and poses no serious
