ABSTRACT

The study presents a systematic methodology to develop micro/nanofibers using electrospinning employing ceramers and other novel materials mixed in solutions of high-performance polymers. The methodology involves identification and selection of novel combinations of loading and high-performance polymers. The resulting nano/microfibers with properties leading to increased mechanical strength, improved sensitivity to contaminants, better filtering capabilities, improved response to electromagnetic stimuli, and desired conductivity. Also, high surface area/volume ratio and fibers with varying functionality, combined with its potential biocompatibility and biodegradable nature, offers tremendous promise for diverse applications in tissue engineering, targeted vaccine delivery, non-thrombogenic materials for blood contacting applications, chemical and biological sensors, system-on-fibers (SoF) and e-textiles. Such characteristics will allow for the creation and improvement of barrier materials for force protection, embedded informational and communication technologies (ICT) devices - signal receiving/communication capability, sensors that respond to environmental contaminants, built-in timed-release or physiological condition based-release therapeutics, filtering of contaminants, biological mimicking for sensing, and optical cloaking – all of which promise direct applications of loaded micro/nano fibers in outerwear used in combat theatre. In addition, a selected application of the loaded electrospun nanofibers in biomedicine will be presented. It was shown that antibiotic loaded biodegradable and biocompatible polymeric electrospun nanofibrous membranes can prevent post-surgery induced intra-abdominal adhesions by providing a physical barrier during wound healing process and at the same time a functional barrier against strains of microorganisms thereby reducing the local inflammatory response. The results of our previous studies including synthesis of biocompatible and biodegradable polymers, production and characterization of electrospun nanofibers from those polymers, their loading with drugs and the release of the drugs from the produced matrices would provide a linkage for the development of new functional barriers for protection applications. The work is complemented by using advanced science convergence methodologies such as automated data analysis, mining and surveillance (ADAMSTM) and technology foresight and road-mapping (TechFARMTM) to provide additional knowledge base. Preliminary data of fibers using loaded high performance polymers will be presented with the objective to fabricate ceramers embedded multi-functional nano/micro fibers for military outerwear and gears that provide an integrated solution path through a revolutionary approach of using ceramers embedded in high performance polymers as materials for suits, masks, and embedded sensors.

Biography:

Prof. Vaseashta currently serves as the Vice Provost of Research and Director of Sponsored Programs and Government Relations. He provides strategic leadership to promote and advance research initiatives and priorities.  Prior to this position, he served as the Director of Research at the Institute for Advanced Sciences Convergence (IASC) and International Clean Water Institute (ICWI) for Norwich University’s Applied Research Institutes. Prior to his appointment at NUARI, Dr. Vaseashta served as a Professor of Physics and Physical Sciences and Director of Research at the Nanomaterials Processing and Characterization Laboratories, Graduate Program in Physical Sciences at Marshall University. Concurrently, he held a visiting/distinguished Professorship at the 3 Nano-SAE Research Centre, University of Bucharest, Romania; Academy of Sciences of Moldova, Chisinau, Moldova; and at the Helen and Martin Kimmel Center of Nanoscale Science at the Weizmann Institute of Science, Israel. In 2007-08, he was detailed as a William C. Foster fellow to the Bureau of International Security and Nonproliferation at the US Department of State working with the Office of Weapons of Mass Destruction and Terrorism and Foreign Consequence Management program. He also served (2009-13) as a Franklin Fellow and strategic S&T advisor in the office of Verification and Transparency Technologies/Arms Verification and Control at the U.S. Department of State. He is a fellow of the American Physical Society (FAPS), Institute of Nanotechnology (FIoN), and the New York Academy of Sciences (FNYAS). He was awarded a Gold medal by the State Engineering University of Armenia for his contribution to Nanotechnology. In addition, he has earned several other fellowships and awards for his meritorious service including 2004/2005 Distinguished Artist and Scholar award. His research interests include counterterrorism, unconventional warfare, Critical-Infrastructure protection, biosecurity, advanced and nano materials for development of chemical-bio sensors/detectors, environmental pollution monitoring/detecting and remediation, and green nanotechnology. Dr. Vaseashta received PhD from the Virginia Polytechnic Institute and State University, Blacksburg, VA in 1990. He authored over 200 research publications, edited/authored seven books on nanotechnology, presented many keynote and invited lectures worldwide, served as the Director of several NATO Advanced Study Institutes (ASI)/Advanced Research workshops (ARW) supported by Emerging Security Challenges Division of the Science for Peace and Security, and served as co-chair of an International Symposium on Nanotechnology and Environmental Pollution Prevention (ISNEPP). He led the U.S. position on Nanotechnology in High Technology Coordination Group (HTCG) to joint US and India delegation. In addition, he served as a member of the U.S. Department of Commerce, NIST, and ANSI delegation to the U.K. representing the U.S. position on Standards in Nanotechnologies in the ISO/TAG to TC-229. He is a member of NATO-SET-040, an exploratory team panel investigating security and surveillance applications of nanotechnology. He serves as an expert counsel to the UNESCO, ObservatoryNANO, COSENT – south-east consortium on Nanotechnologies on NANO-Science and Technologies, and S&T advisor to NATO. He is an active member of several national and international professional organizations.
