Preparation of Cellulose Nanocrystals Using an Ionic Liquid
(726-731) Journal of Polymers and the Environment 19 #3 (2011)
Man eta l, Malaysia, prepared cellulose nanocrystals by treating microcrystalline cellulose with 1-butyl-3-methylimidazolium hydrogen sulphate ionic liquid.  XRD results showed no changes in type of cellulose after the treatment with ionic liquid, however, high crystallinity index was observed in the ionic liquid treated sample.  Cellulose nanocrystals, having length around 50–300 nm and diameter around 14–22 nm were observed in the ionic liquid treated sample under FESEM and TEM, and similar patterns of peaks as that of microcrystalline cellulose were observed for cellulose nanocrystals in the FTIR spectra.  (RDC 8/23/2011)

Preparation and characterization of cellulose microspheres
(135-142) Cellulose 18 #1 (2011)
Thümmler et al, Germany and Austria  synthesized cellulose microspheres with a particle size below 5 μm and narrow size distribution. After activation and functionalization with antibodies, these particles served as adsorbents in suspension-based extracorporeal blood purification systems, such as the Microspheres-Based Detoxification System.   (RDC 2/11/2011)
