Bacterial Cellulose Nanocomposites Developed by in-situ Fermentation

Osorio M., Restrepo D., Castro C., Montoya U., Zuluaga R., Gañán P., Universidad Pontificia Bolivariana, CO

Some bacteria such as Gluconacetobacter synthesize cellulose nanofibrills (BC) through the polymerization of glucose and subsequent extrusion outside the cell. In static conditions, the bacteria produce a three-dimensional network, a type of pellicule, which can [...]

The Effect of Starch Structure on Starch-based Nanocomposite

Zhou J.H., Hanna M.A., South China Agricultural University, CN

The effect of starch structure on starch based nanocomposite Starches, including high amylose cornstarch, normal cornstarch, and waxy cornstarch, were gelatinized and mixed with nanoclay aqueous dispersion and different amount plasticizer. The mixtures were then [...]

From Helical Starch Inclusion Complexes to Supramolecular Starch Assemblies

Conde-Petit B., Nuessli J., Heinemann C., Escher F., ETH Zürich, CH

Starch, in particular the linear amylose fraction has the ability ot form helical inclusion complexes with suitable guest molecules like monoglycerides, linear alcohols, lactones or terpenes. The helical amylose segments have a strong tendency to [...]
