Electron microdiffraction reveals the nanoscale twist geometry of cellulose nanocrystals

Y Ogawa - Nanoscale, 2019 - pubs.rsc.org
Nanocellulose consisting of crystalline cellulose nanoparticles has high potential to serve
as a building block for bio-based functional materials. The intrinsic chirality of cellulose …

High performance, fully bio‐based, and optically transparent wood biocomposites

C Montanari, Y Ogawa, P Olsén… - Advanced …, 2021 - Wiley Online Library
The sustainable development of engineering biocomposites has been limited due to a lack
of bio‐based monomers combining favorable processing with high performance. Here, the …

Structural color from cellulose nanocrystals or chitin nanocrystals: self-assembly, optics, and applications

…, K Ballu, Q Shen, Z Lu, Y Ogawa… - Chemical …, 2023 - ACS Publications
Widespread concerns over the impact of human activity on the environment have resulted in
a desire to replace artificial functional materials with naturally derived alternatives. As such, …

[HTML][HTML] Advancing plant cell wall modelling: Atomistic insights into cellulose, disordered cellulose, and hemicelluloses–A review

A Khodayari, U Hirn, S Spirk, Y Ogawa, D Seveno… - Carbohydrate …, 2024 - Elsevier
The complexity of plant cell walls on different hierarchical levels still impedes the detailed
understanding of biosynthetic pathways, interferes with processing in industry and finally limits …

Drying-induced bending deformation of cellulose nanocrystals studied by molecular dynamics simulations

Y Ogawa, Y Nishiyama, K Mazeau - Cellulose, 2020 - Springer
Drying cellulosic materials from their water-swollen state can collapse their ultrastructure
and alter their macroscopic material properties such as mechanical strength and water-…

Photo-induced semimetallic states realised in electron–hole coupled insulators

K Okazaki, Y Ogawa, T Suzuki, T Yamamoto… - Nature …, 2018 - nature.com
Using light to manipulate materials into desired states is one of the goals in condensed
matter physics, since light control can provide ultrafast and environmentally friendly photonics …

Comprehensive morphological and structural investigation of cellulose I and II nanocrystals prepared by sulphuric acid hydrolysis

WPF Neto, JL Putaux, M Mariano, Y Ogawa… - Rsc Advances, 2016 - pubs.rsc.org
Cellulose nanocrystals (CNCs) were produced from eucalyptus wood pulp using three
different methods: (i) classical sulphuric acid hydrolysis (CN-I), (ii) acid hydrolysis of cellulose …

Chitin-based barrier immunity and its loss predated mucus-colonization by indigenous gut microbiota

K Nakashima, S Kimura, Y Ogawa, S Watanabe… - Nature …, 2018 - nature.com
Mammalian gut microbiota are integral to host health. However, how this association began
remains unclear. We show that in basal chordates the gut space is radially …

Estimating the strength of single chitin nanofibrils via sonication-induced fragmentation

Y Bamba, Y Ogawa, T Saito, LA Berglund… - …, 2017 - ACS Publications
We report the mechanical strength of native chitin nanofibrils. Highly crystalline α-chitin
nanofibrils were purified from filaments produced by a microalgae Phaeocystis globosa, and two …

Controlling the self-assembly behavior of aqueous chitin nanocrystal suspensions

…, LM Steiner, RM Parker, Y Ogawa… - …, 2019 - ACS Publications
As with many other biosourced colloids, chitin nanocrystals (ChNCs) can form liquid crystalline
phases with chiral nematic ordering. In this work, we demonstrate that it is possible to …
