@article{1020, abstract = {Cellulose is the most abundant biopolymer on Earth. Cellulose fibers, such as the one extracted form cotton or woodpulp, have been used by humankind for hundreds of years to make textiles and paper. Here we show how, by engineering light-matter interaction, we can optimize light scattering using exclusively cellulose nanocrystals. The produced material is sustainable, biocompatible, and when compared to ordinary microfiber-based paper, it shows enhanced scattering strength (×4), yielding a transport mean free path as low as 3.5 μm in the visible light range. The experimental results are in a good agreement with the theoretical predictions obtained with a diffusive model for light propagation.}, author = {Caixeiro, Soraya and Peruzzo, Matilda and Onelli, Olimpia and Vignolini, Silvia and Sapienza, Riccardo}, issn = {19448244}, journal = {ACS Applied Materials and Interfaces}, number = {9}, pages = {7885 -- 7890}, publisher = {American Chemical Society}, title = {{Disordered cellulose based nanostructures for enhanced light scattering}}, doi = {10.1021/acsami.6b15986}, volume = {9}, year = {2017}, }
