Dr. Karen Lozano, Julia Beecherl Endowed Professor and Director of the UTRGV Nanotechnology Center obtained an MS and Doctorate degree from Rice University in Houston, TX. She is the recipient of several awards such as the NSF CAREER award, the HENAAC Most Promising Scientist, and 2015 Engineer of the Year by Great Minds in STEM. Lozano has published over 100 refereed reviewed journal articles and has over 250 proceedings, invited talks, and conference presentations. She is a prolific inventor (with over 40 patents/patent applications), she co-founded Fiberio Technologies Corporation, which focuses on the industrial production of nanofibers by Forcespinning® technology. This new technology has received several awards such as the Innovations That Could Change the Way You Manufacture granted by the Society of Manufacturing Engineers and the R&D 100. Dr. Lozano enjoys instilling in k-12 students a passion for engineering careers, she has developed numerous summer camps, workshops and presentations and more recently launched a YouTube Channel, “Karen’s Lab” to promote STEM based innovation.
Summary: Nanofibers (NFs) are defined by the academic community and commercial sector as fibers with diameters of <100 nm and <500 nm respectively. NFs have garnered remarkable attention from the scientific community on a quest to both understand the underlying kinematics of formation and overall properties and characteristics to use these novel structures in real-world applications. The potential applications can be broadly divided in the following areas: filtration, medical, energy, smart textiles, protective, structural, electrical, and optical. For example, nonwoven fibers used in filtration applications are an important part of the global nonwoven industry, making up the 4th largest end-use market in North America. The global market for nonwoven filter media has been estimated to be up to US $700 billion by the year 2020, not considering other filtration related applications such as surgical gowns and protective clothing for chemical and biological warfare agents. The available processing techniques for NF development are: wet chemistry methods, solution and melt blowing, and spinning methods (wet, dry and melt spinning). These methods present serious scalability issues for NF manufacturing. This talk will introduce the audience to a newly developed NF manufacturing technology.
