Journal ArticleDOI
Fullerene-based bistable devices and associated negative differential resistance effect
TL;DR: In this paper, the authors observed bistability in single layer devices made from fullerenes (C60) mixed with polystyrene (PS) and sandwiched between two Al electrodes.
Journal ArticleDOI
A facile template-free approach to magnetodriven, multifunctional artificial cilia.
Jaakko V. I. Timonen,Christoffer Johans,Kyösti Kontturi,Andreas Walther,Olli Ikkala,Robin H. A. Ras +5 more
TL;DR: Flexible and magnetic artificial cilia were grown on various substrates by a facile bottom-up approach based on template-free magnetic assembly and suggest applications as an externally controllable surface.
Journal ArticleDOI
Effect of Side Chain Rigidity on the Elasticity of Comb Copolymer Cylindrical Brushes: A Monte Carlo Simulation Study
TL;DR: In this article, the results of a Monte Carlo simulation study of isolated comb copolymer cylindrical brushes are presented, showing that the conformational characteristics of molecules consisting of a flexible backbone densely grafted with side chains strongly depend on the rigidity of the side chains, which is exemplified by using both flexible and totally rigid side chains.
Journal ArticleDOI
Transition to reinforced state by percolating domains of intercalated brush-modified cellulose nanocrystals and poly(butadiene) in cross-linked composites based on thiol-ene click chemistry.
TL;DR: The shown simple concept of percolative intercalated nanocomposites suggests searching for more general biomimetic compositions involving several deformation mechanisms for improved mechanical properties.
Journal ArticleDOI
Cationic polymer brush-modified cellulose nanocrystals for high-affinity virus binding
Henna Rosilo,Jason R. McKee,Eero Kontturi,Tiia Koho,Vesa P. Hytönen,Olli Ikkala,Mauri A. Kostiainen +6 more
TL;DR: The results show the feasibility of the modified CNCs in virus binding and concentrating, and pave the way for their use as transduction enhancers for viral delivery applications.
