Seminar:"Green Materials and Processes: From Advanced Composites to Nanofilters and from Wound Healing to Hair Styling" by Dr. Anil N. Netravali

Event Date: 
Monday, 11 January 2016 - 11:30am

Dr. Anil N. Netravali (Jean and Douglas McLean Professor in Fiber Scienceand Apparel Design, Department of Fiber Science & Apparel Design, CornellUniversity, USA) will present a seminar on January 11 at 11:30 am.


Abstract:
Fiber reinforced composites are used from circuit boards to
sports gear and from airplane parts to housing panels. Most of thesecomposites use fibers and resins made from petroleum. They have two major problems. First: petroleum is a non-sustainable commodity and isestimated to last about 50 yrs at the current rate of consumption.Second: these composites do not degrade for several decades under normal environmental conditions. Since they cannot be reused or recycled easily,most of them end up in landfills at the end of their life. GreenComposites, on the other hand, are made using plant based resins and fibers. They are sustainable, yearly renewable and fully degradable. Atthe end of their life they can be easily disposed of or composted. Whilemajority of green composites fabricated using common plant based fibers such as jute, kenaf, linen, ramie, hemp, etc. can be used innon-structural applications, some advanced green composites using high strength liquid crystalline cellulose fibers can be used for primarystructural applications. They have mechanical properties comparable tocomposites made using fibers such as Kevlar? and glass. The first part of the presentation will review the development of soy based resins andadvanced green composites. In the second part of the presentation otherresearch on green nanofilters, nanocellulose fibers for wound healing and soy based hair styling will be discussed.Biosketch:
Dr. Netravali is a member of the American Chemical Society, the
Fiber Society and the American Nano Society. He is an Adjunct Professor atthe Universidade Federal do Amazonas (UFAM), Manaus, Brazil, and at Tuskegee University, Tuskegee, AL. He has also been an InternationalResearch Fellow at the Composites Center at Doshisha University, Kyoto,Japan. He serves on the Editorial Advisory Boards of seven research journals; Composites Science and Technology (CST), Journal of BiobasedMaterials and Bioenergy (JBMB), Journal of Renewable Materials (JRM),Reviews of Adhesion and Adhesives (RAA), Journal of Engineered Fibers and Fabrics (JEFF), Fibers and Textile Research Journal (TRJ). He is amember of the Advisory Committee of the International Workshop on Green Composites, a member of the International Scientific Committee for theAmazonic Green Materials and Processes Meetings as well as a member of theScientific Committee. He is a Faculty Fellow at the David R. Atkinson Center for a Sustainable Future at Cornell University. He is also amember of the Engineering Panel of the Research Grants Council (RGC) ofHong Kong. After obtaining Ph.D. from North Carolina State University in 1984 Dr. Netravali joined the Department of Materials Science andEngineering at Cornell University as a postdoctoral associate. In 1985 he joined the Department of Mechanical Engineering as a research associateand in August of 1987 he joined the Department of Fiber Science & ApparelDesign as an assistant professor of Fiber Science. His main research is in the field of Fiber Reinforced Composites and Green Materials andProcesses. Within the composites area the primary focus of his group has been in developing Green resins from plant-based proteins and starches andreinforcing them using plant-based fibers to fabricateenvironment-friendly, green composites for a variety of applications. A second focus of his group is to develop new green nanofibers from proteinsand starches for a variety of applications including high efficiencyfiltration and bacterial nanocellulose from food and agricultural waste for composite, medical and other applications.He has been an author or co-author of over 125 refereed papers and bookchapters. He has given over 200 presentations including Keynote addresses, Distinguished, Plenary and Invited presentations. He has 2co-edited books to his credit and holds 8 patents.
