Data on Nanocrystals Reported by Researchers at Lulea University of Technology (Process scale up and characterization of wood cellulose nanocrystals hydrolysed using bioethanol pilot plant)
By a News Reporter-Staff News Editor at Biotech Week -- Current study results on Nanocrystals have been published. According to news reporting out of Lulea, Sweden, by NewsRx editors, research stated, "The paper discusses the isolation of cellulose nanocrystals (CNCBE) from wood resources by integrating the processing with pilot-scale bioethanol processing unit. The nanocrystals were isolated from cellulose obtained by acid pretreatment of wood chips in a bioethanol pilot-scale facility, followed by a series of chemical processes and subsequent homogenization using a lab-scale homogenizer."
Our news journalists obtained a quote from the research from the Lulea University of Technology, "The isolated nanocrystals had diameters of 5-15 nm, cellulose I crystalline structure and formed a thick semi-transparent gel at low concentration (2 wt%). XPS data showed that these nanocrystals had predominantly O=C-O surface groups which also contributed to its high negative zeta potential. Casted CNCBE films showed excellent mechanical performance (200 MPa of strength, 16 GPa of modulus) and transparency and were also found to be cytocompatible."
According to the news editors, the research concluded: "The developed process route resulted in high-quality nanocellulose crystals with a yield of 600 g/day."
