SUMMARY:Workshop / Seminar:ChE SEMINAR: Orlin Velev\, North Carolina State University
DESCRIPTION:A reception with light refreshments will be held in the B32 lobby before the seminar from 1-1:30 p.m.\n\nAbstract: The replacement of synthetic nanomaterials with biodegradable alternatives made from abundant and sustainable raw materials is a challenge of high societal importance. We will discuss how the process of antisolvent precipitation under shear enables the formation of diverse classes of biopolymer structures\, including nanoparticles\, rods\, nanofibers\, nanoribbons\, sheets\, and hierarchical nanomaterials. Specifically\, we will focus on the unique capabilities enabled by a new class of soft dendritic colloids (SDCs) with hierarchical morphology (Nature Materials 18:1315\, 2019). The fractal branching and contact splitting phenomena enable a range of highly unusual properties of the SDCs – gelation at very low volume fractions\, strong adhesion to surfaces and to each other\, and ability to form new types of gels\, nonwoven sheets and reinforced biocomposites. Alginate SDCs can be used in hierarchical hydrogel networks with synergistic combination of the colloidal and molecular networks (Nature Comm. 12:2834\, 2021). One emerging application of the SDCs with high societal impact is as cleaners that capture microplastics for water remediation (Langmuir 40:5923\, 2024). We further make use of the unique properties of the SDCs in “active microcleaners\,” which are made of chitosan and infused with a small amount of fatty acid\, enabling them to self-propel and self-disperse in water by the Marangoni effect. The rehydrated SDCs could enable the cleanup of microplastics in various types of aquifers\, including saline seawater. Finally\, we report a class of high-performance multifunctional composite films made of biopolymers: agarose matrix reinforced with chitosan SDCs. Owing to the highly entangled hierarchical SDCs network\, the reinforced biocomposites have excellent mechanical performance\, high optical transmittance\, hydrostability\, bactericidal activity and soil biodegradability (Cell Rep. Phys. Sci. 4:101732\, 2023). The results suggest a universal strategy for manufacturing of natural-source composite materials that can serve as substitutes for petroleum-based plastics. \n\nSpeaker Bio: Dr. Orlin Velev is a Frank and Doris Culberson Distinguished Professor at NC State University. He received his PhD degree from the University of Sofia\, Bulgaria (1996)\, while also performing research for one year in Japan. After a postdoc at the University of Delaware Velev joined NC State University in 2001. He has established a record of innovative research in the assembly of colloidal nanostructures with magnetic\, electrical\, and photonic functionality\, biosensors\, microfluidics and manufacturing of environmentally friendly and sustainable nanomaterials. Velev has contributed more than 240 publications and has presented more than 310 invited presentations. He has received numerous awards\, including NSF Career\, AIChE Andreas Acrivos Award for Professional Progress\, AIChE Braskem Award for Excellence in Materials Engineering and Science\, and ACS Langmuir Lecturer.

SUMMARY:Workshop / Seminar:Adapting Traditional Diversity Research to Be Oriented Towards Change: The Example of the Audio for Inclusion Project
DESCRIPTION:Abstract: This talk examines our typical practices for research on diversity\, equity\, and inclusion and the researcher’s role in initiating change. As critical scholars generally agree\, the system of engineering education contains inequities. If remaining neutral in light of oppression means siding with the oppressor\, I see an important role of the engineering education scholar to focus on those inequities and to take a role towards shifting them. On the contrary\, I see most broadening participation research as functioning for knowledge generation\, say\, about the marginalization of historically excluded populations or about the practices that support students\, without much conceptualization for how the research products will be utilized to shift the inequities. While useful\, we should recognize that knowledge generation alone is inert regarding broadening participation as a shared mission\, and to be meaningful broadening participation work should actively engage in change projects. I explore the idea of a simple change model to help us conceptualize how change does or does not result from our research work\, through our role and our understanding of the involvement and influence of other key stakeholders. I call for change-oriented broadening participation research as a necessary movement\, and suggest adapting existing qualitative and quantitative research approaches to have a more strategic and explicit plan to bring about change. As an example\, I showcase an NSF-funded project\, Audio for Inclusion\, which adapts qualitative research about marginalized student groups to provide accessible and productive feedback for engineering faculty. I will showcase one or more audio narratives from the project and we can brainstorm together the lessons we learn from these student narratives. I will conclude with some principles about how to move towards change-oriented broadening participation research in different areas.\n\nBio: Dr. Stephen Secules is an Assistant Professor in the School of Universal Computing\, Construction\, and Engineering Education at Florida International University. Secules holds a joint appointment in the STEM Transformation Institute\, a secondary appointment in the Department of Mechanical and Materials Engineering. In addition\, he leads the Equity Research Group\, serves as a faculty fellow for Office to Advance Women Equity and Diversity\, and is a 2023 recipient of the FIU Senate Excellence in Teaching Award. He has bachelor degrees in engineering from Dartmouth College\, a master’s in Architectural Acoustics from Rensselaer Polytechnic Institute\, and a PhD in Education (Curriculum and Instruction) from the University of Maryland. He has prior work experience in acoustical consulting and was a visiting faculty member at Purdue University. His research has focused on culture and equity in engineering education\, particularly undergraduate contexts\, pedagogy\, and student support. Through his work he aims to use critical qualitative\, video-based\, participatory\, and ethnographic methods to look at everyday educational settings in engineering and shift them towards equity and inclusion.
