Findings from Northeast Forestry University Update Understanding of Carbohydrate Polymers (Fabrication and characterisation of ?-chitin nanofibers and highly transparent chitin films by pulsed ultrasonication)

By a News Reporter-Staff News Editor at Journal of Technology -- Current study results on Carbohydrate Polymers have been published. According to news reporting from Harbin, People's Republic of China, by VerticalNews journalists, research stated, "?-Chitin nanofibers were fabricated with dried shrimp shells via a simple high-intensity ultrasonic treatment under neutral conditions (60 KHz, 300 W, pH=7). The diameter of the obtained chitin nanofibers could be controlled within 20-200 nm by simply adjusting the ultrasonication time."

The news correspondents obtained a quote from the research from Northeast Forestry University, "The pulsed ultrasound disassembled natural chitin into high-aspect-ratio nanofibers with a uniform width (19.4 nm after 30 min sonication). The EDS, FTIR, and XRD characterisation results verified that ?-chitin crystalline structure and molecular structure were maintained after the chemical purification and ultrasonic treatments. Interestingly, ultrasonication can slightly increase the degree of crystallinity of chitin (from 60.1 to 65.8)."

According to the news reporters, the research concluded: "Furthermore, highly transparent chitin films (the transmittance was 90.2% at a 600 nm) and flexible ultralight chitin foams were prepared from chitin nanofiber hydrogels."
