**About the Editors**

**Armando J. D. Silvestre** is a Full Professor and the Head of the Department of Chemistry of the University of Aveiro (Portugal). His research interests are focused on the biorefinery concept development, namely through the sustainable extraction and upgrading of added-value compounds from biomass addressing mainly bioactive compounds through the use of benign solvents (using ionic liquids, deep eutectic solvents, and supercritical CO2); new biobased polymers derived from 2,5-furandicarboxylic acid and new functional (nano)composite materials and biomaterials based on biopolymers and cellulose (nano)fibers. He has published 1 book, 24 book chapters, 4 patents, 350+ papers, h-index 57, 11,000+ citations.

**Carmen S.R. Freire** is a Principal Researcher at CICECO—Aveiro Institute of Materials (University of Aveiro, Portugal) in the Biorefinery and bio-based materials research area. Her research interests include the production and application of biogenic nanofibers (bacterial cellulose and protein fibrils), nanostructured biocomposites and hybrid materials; bio-based materials for biomedical applications (wound healing, drug delivery, and 3D bioprinting), biocomposites and functional paper materials; chemical modification of (nano)cellulose fibers and other polysaccharides and their characterization and applications. C. Freire is the author of more than 220 papers (with 7500+ citations, h-index 52), 5 patents, 9 book chapters, and more than 180 communications in international and national conferences.

**Carla Vilela** is an assistant researcher at CICECO—Aveiro Institute of Materials (University of Aveiro, Portugal) and her main research interest includes the sustainable use of biopolymers, namely polysaccharides (e.g., nanocellulose, pullulan, chitosan) and proteins (e.g., gelatin, lysozyme), for the development of novel functional nanostructured materials for both technological (e.g., active food packaging and fuel cells) and biomedical (e.g., drug delivery and wound healing) applications. She is the author of 62 SCI papers (h-index: 22; citations: 1600+), 1 book, 5 book chapters, 5 conference proceedings, and more than 90 communications in national and international conferences.
