TL;DR: Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.
Journal ArticleDOI
Functional materials based on self-assembly of polymeric supramolecules
TL;DR: H Hierarchically structured materials obtained by applying different self-organization and recognition principles and directed assembly form a basis for tunable nanoporous materials, smart membranes, preparation of nano- objects, and anisotropic properties, such as proton conductivity.
Journal ArticleDOI
Mechanically Durable Superhydrophobic Surfaces
TL;DR: While the fragility of superhydrophobic surfaces currently limits their applicability, development of mechanically durable surfaces will enable a wide range of new applications in the future.
Journal ArticleDOI

TL;DR: It is shown that freeze-dried bacterial cellulose nanofibril aerogels can be used as templates for making lightweight porous magnetic aerogel, which can be compacted into a stiff magnetic nanopaper.
Journal ArticleDOI
Hydrophobic nanocellulose aerogels as floating, sustainable, reusable, and recyclable oil absorbents.
TL;DR: By functionalizing the native cellulose nanofibrils of the aerogel with a hydrophobic but oleophilic coating, such as titanium dioxide, a selectively oil-absorbing material capable of floating on water is achieved.
