ABSTRACTHydrogels are flexible materials that typically accommodate elongation with positive Poisson’s ratios. Auxetic property, i.e., the negative Poisson’s ratio, of elastic materials can be macroscopically implemented by the structural design

ABSTRACT Nanopapers fabricated from cellulose nanofibers (CNFs) drastically swell to form hydrogels when they are in contact with water. This gelation makes contrast with conventional papers that simply deform without drastic volume increase. While t

Film materials made of cellulose nanofibers (CNFs), i.e., so-called nanopapers, are fabricated from aqueous dispersions of CNFs. The drying in the container causes the phase transition from sol to gel and final state of transparent film. The nonequil

Nanopapers fabricated from cellulose nanofibers (CNFs) are flexible for bending while they are rather stiff against stretching, which is a common feature shared by conventional paper-based materials in contrast with typical elastomers. Cellulose nano

The processes of wetting and solvent evaporation in the drying sessile conductive ink droplets formed by inkjet printing are clarified for characterization to be referenced for diverse applications. The electric resistance of the PEDOT:PSS ink line p

We report that the addition of a small amount of cellulose nanofibers (CNFs) into an aqueous dispersion of colloidal particles suppresses the coffee-ring effect when the dispersion dries on a solid substrate, as revealed by the computational analysis

We propose a technique to evaluate the field of diffusion coefficient for particle dispersion where the Brownian motion is heterogeneous in space and single particle tracking (SPT) analysis is hindered by high concentration of the particles and/or th

A carbon nanotube junction consists of two connected nanotubes with different diameters. It has been extensively investigated as a molecular electronic device since carbon nanotubes can be metallic and semiconductive, depending on their structure. Ho
