DESCRIPTION:Dr. Nathalie Lavoine\, NC State University\, USA\nCellulose na
 nomaterials (CNMs) are a new class of cellulose particles with properties 
 and functionalities distinct from molecular cellulose and wood pulp. As a 
 result\, they are being developed for applications that were once thought 
 impossible for cellulosic materials.\nMomentum is growing in CNM research 
 and development\, and first stages of commercialization in this field have
  been initiated owing to the unique combination of sustainability and perf
 ormance (e.g.\, high mechanical strength\, low density\, large-scale produ
 ction potential) that CNMs offer. Target applications include\, but are no
 t limited to\, composites for automotive\, diapers\, cosmetic oils and cre
 ams\, food-packaging\, and scaffolds for tissue regeneration\, among other
 s.\n\nOver the last 10 years\, the bulk of my research has been undertaken
  to develop a deeper appreciation of the structure-processing-properties r
 elationships of naturally ubiquitous synthons such as cellulose so they ma
 y be engineered to display advanced functional materials. Essentially\, th
 e overall application goal is the creation of sustainable and greener anal
 ogous counterparts to petroleum-based synthons such as propylene (for poly
 propylene).\nOne of my synthon targets has been CNMs as building blocks fo
 r engineering packaging substrates and coatings\, stimuli-responsive syste
 ms (e.g.\, drug delivery\, thermal comfort textiles) and functional porous
  materials (e.g.\, thermal insulating foams).\nDuring this research semina
 r\, I will give an overview on the potentials of CNMs for the sustainable 
 design and development of packaging substrates through the presentation of
  my research activities. I will discuss my vision on the challenges of env
 ironmentally sustainable packaging and share\, via examples from my resear
 ch work\, my current and future plans to address these challenges.\nBio: S
 ince 2018\, Dr. Lavoine is an Assistant Professor in the Department of For
 est Biomaterials\, College of Natural Resources\, at NC State University (
 Raleigh\, NC\, US).\nHer research interests are in the area of renewable n
 anomaterials\, biomass valorization and conversion\, mass transfer in nano
 porous network\, active packaging\, and sustainable materials processing.\
 n\nPrior to her appointment at NC State\, she was a Research Fellow from 2
 016-2018 in Materials Chemistry at Stockholm University (Sweden). Under th
 e direction of Prof. Bergström\, she developed new strategies for produci
 ng super-insulating nanocomposite foams. From 2014-2016\, she was an Inter
 national Research Fellow of the Japan Society for the Promotion of Science
 \, at The University of Tokyo (Japan). Under the direction of Prof. Isogai
 \, she created TEMPO-oxidized cellulose nanofibrils that were surface modi
 fied by amine-functionalized compounds to improve their thermal properties
  in order to develop high-performance nanocomposites.\nDr. Lavoine receive
 d her Ph.D. in 2013 at the Laboratory of Pulp and Paper Science and Graphi
 c Arts (Laboratoire du Génie des Procédés Papetiers (LGP2)) in Grenoble
 \, France\, under the direction of Dr. Bras and Dr. Desloges. In her thesi
 s work\, entitled “Design\, Processing and Characterization of Innovativ
 e Functional Bio-nano-materials for Packaging\,” she developed antibacte
 rial food packaging substrates using cellulose nanofibrils as a controlled
  release system of actives.\nShe received her Master’s degree of Enginee
 ring (French Diplôme d’Ingénieur) in 2010\, in Paper Science and Engin
 eering from Grenoble Institute of Technology (Grenoble INP-Pagora\, France
 ). As part of this degree program\, she worked on an industry-funded proje
 ct where she developed proprietary food packaging materials from bio-based
  resources. She also has experience working in the packaging industry as a
 n engineer and as an intern\, including a 3-month position in Germany.\n
