Journal ArticleDOI
Nanocrystalline cellulose applied simultaneously as the gate dielectric and the substrate in flexible field effect transistors
Diana Gaspar,Susete N. Fernandes,A. G. de Oliveira,Juliana Gomes Fernandes,Paul Grey,Rita V. Pontes,Luís Pereira,Rodrigo Martins,Maria Helena Godinho,Elvira Fortunato +9 more
TL;DR: The results obtained are comparable to ones produced for conventional cellulose paper, marking this out as a promising approach for attaining high-performance disposable electronics such as paper displays, smart labels, smart packaging, RFID (radio-frequency identification) and point-of-care systems for self-analysis in bioscience applications, among others.
Journal ArticleDOI
Mind the Microgap in Iridescent Cellulose Nanocrystal Films.
Susete N. Fernandes,Pedro Almeida,Pedro Almeida,Nuno Monge,Nuno Monge,Nuno Monge,Luis E. Aguirre,Dennys Reis,Cristiano L. P. Oliveira,Antônio Martins Figueiredo Neto,Pawel Pieranski,Maria Helena Godinho +11 more
TL;DR: A new photonic structure is produced from cellulose nanocrystal iridescent films reflecting both right and left circularly polarized light that is reversibly tuned by the application of an electric field or a temperature variation.
Journal ArticleDOI
Cellulose-Based Biomimetics and Their Applications
Ana P. C. Almeida,João P. Canejo,Susete N. Fernandes,Coro Echeverria,Pedro Almeida,Pedro Almeida,Maria Helena Godinho +6 more
TL;DR: Five sections describe cellulose-based materials with characteristics that are inspired by gratings that exist on the petals of the plants, structurally colored materials, helical filaments produced by plants, water-responsive materials in plants, and environmental stimuli-responsive tissues found in insects and plants.
Journal ArticleDOI
Functional Stimuli-Responsive Gels: Hydrogels and Microgels
TL;DR: A new generation of functional stimuli-responsive polymer hydrogels able to self-shape (shape-memory) and/or self-repair is focused on, which could be considered as the closing loop for smart polymeric gels.
Journal ArticleDOI
Structural Color and Iridescence in Transparent Sheared Cellulosic Films
Susete N. Fernandes,Yong Geng,Silvia Vignolini,Beverley J. Glover,A. C. Trindade,João P. Canejo,Pedro Almeida,Pedro Almeida,Pedro Brogueira,Maria Helena Godinho +9 more
TL;DR: In this paper, small amounts of nanocrystalline cellulose (NCC) rods in the precursor liquid-crystalline solutions do not disturb the optical properties of the solutions but enhance the mechanical characteristics of the films and affects their iridescence.
