New Nanoparticles Data Have Been Reported by Investigators at National Chemical Laboratory

May 6, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Research findings on Nanoparticles are discussed in a new report. According to news reporting from Maharashtra, India, by NewsRx journalists, research stated, "Agricultural residues derived cellulose was used to synthesize a new series of carboxy functionalized cellulosic nanoparticles (quasi-spherical shaped, 13.2-21.5% carboxyl content) and macro-sized 6-carboxycelluloses (long-fibril shaped, 1.7-22% carboxyl content). The DP (50-70) and yield (upto 46%) of nanoparticles were manipulated by controlling the reaction temperature and time."

The news correspondents obtained a quote from the research from National Chemical Laboratory, "TGA/DTG thermographs of the carboxycelluloses gave thermostability data and co-related well with the residual crystalline, amorphous, and anhydroglucuronic acid content. The particle shape and size had no effect on the thermal stability."

According to the news reporters, the research concluded: "Some derivatives were fully or partially soluble in aqueous alkali and non-aqueous solvents, which can lead to increased versatility of these polymers."
