Reports from K.M.O. Hakansson and Co-Researchers Add New Data to Findings in General Science (Hydrodynamic alignment and assembly of nanofibrils resulting in strong cellulose filaments)

By a News Reporter-Staff News Editor at Science Letter -- Current study results on Science have been published. According to news reporting originating from Stockholm, Sweden, by NewsRx correspondents, research stated, "Cellulose nanofibrils can be obtained from trees and have considerable potential as a building block for biobased materials. In order to achieve good properties of these materials, the nanostructure must be controlled."

Our news editors obtained a quote from the research, "Here we present a process combining hydrodynamic alignment with a dispersion-gel transition that produces homogeneous and smooth filaments from a low-concentration dispersion of cellulose nanofibrils in water. The preferential fibril orientation along the filament direction can be controlled by the process parameters. The specific ultimate strength is considerably higher than previously reported filaments made of cellulose nanofibrils. The strength is even in line with the strongest cellulose pulp fibres extracted from wood with the same degree of fibril alignment. Successful nanoscale alignment before gelation demands a proper separation of the timescales involved."

According to the news editors, the research concluded: "Somewhat surprisingly, the device must not be too small if this is to be achieved."
