This week’s Engineering Research Center-Bioengineering Joint Seminar, Friday February 7, 11 a.m., McNair Hall, Auditorium:
Topic: Electrospun Meta-aramid Mats and Their Application
Dr. Hak Yong Kim
Speaker: Dr. Hak Yong Kim, Professor of Bio-Info-Nano Fusion Technology and Professor of Organic Materials and Fiber, Chonbuk National University, Jeonbuk, Korea. Dr. Kim’s areas of research include biomaterials, polymeric composites and functional materials. He has 245 refereed journal publications with a total of over 5,200 citations. He holds 6 U.S. patents and 80 Korean patents.
Abstract: The effect of salt formation during condensation polymerization on the morphology of electrospun meta-aramid fibers was investigated. The presence of a by-product salt (calcium chloride, CaCl2) improved the electrospinnability of the meta-aramid solution and induced the formation of a spider-web-like structure in the mats.
The effect of the concentration of the solution and applied voltage on the formation of the spider-web-like fibrous structure was investigated. FE-SEM images indicated that the very thin fibers were uniformly distributed with thick fibers throughout the mats in the form of a spider-web-like structure. TGA showed that the thermal stability of the electrospun meta-aramid mats was affected by CaCl2.
The observed enhancement in the thermal and mechanical properties of the mats, which was attributed to the formation of the spider-web-like structure, may increase the number of potential applications of meta-aramid, such as second battery separator, water/air filtration, protective clothing and electrical insulation.

Topic: Nanobioelectronics: Convergence of Microsystems, Nanotechnology and Bioengineering
Speaker: Dr. Shyam Aravamudhan, Assistant Professor, Joint School of Nanoscience and Nanoengineering
Abstract: Nanobioelectronics is an emerging field at the intersection of semiconductor nano/microfabrication, biology, and electronics, with the goal of novel devices for disease diagnostics, regenerative medicine, and even for advanced computing. In this talk, Dr. Aravamudhan will present the current work being done in the lab in this emerging field with a particular emphasis on (a) multi-modal diagnostic device-on-chip, (b) microsystem-based regenerative tissue engineering and (c) methods to understand toxicity of engineering nanomaterials.

The Gateway University Research Park has created space for use as a business incubator for nanobio start-ups. The “NanoBio Launchpad” is located at the park’s south campus in the building next door to the Joint School of Nanoscience and Nanoengineering (JSNN).
The 2,500 square foot space contains three offices, eight workstations and a shared laboratory.
From The Business Journal:
“Ideally, Launchpad occupants will be able to benefit from the close proximity to the JSNN and the new Nanomanufacturing Innovation Consortium, through which private-sector nano organizations gain access to the expensive equipment and brainpower at the school. In the best case scenario for Gateway, companies that get started in the Launchpad will grow into traditional space in the research park’s current and future buildings.”
The full Business Journal article is here.
The Launchpad is in the Research Facility One building. The building also contains the U.S. Department of Agriculture, Natural Resource Conservation Service and East National Technical Support Center; Advaero Technologies, a N.C. A&T nanotech spin-off company; and Gateway’s administrative offices.
The Gateway research park and JSNN both are operated jointly by N.C. A&T and UNC Greensboro.

The Joint School of Nanoscience and Nanoengineering has launched a program with Bharati Vidyapeeth Deemed University (BVDU) that will bring master’s students from India to the joint school.
“Their students complete the coursework for their M.Tech degree at BVDU, and a small number will come to JSNN to perform their research for their degree,” said Dr. Jim Ryan, JSNN dean.
“The program is very competitive, and the students who will come to JSNN are of the highest caliber. We expect four to arrive in January.”
Some of the students may have an opportunity to stay at the JSNN for their doctoral degrees, Ryan said.
Faculty advisor Vernal Alford and the 2012 ERC Young Scholars (from left): Shira Chandler, Dondre McCaskill, Brianna Hargett, Aditya Badve, Ephraim Bililign and Aditya Garg.
If you ask Greensboro high school student Brianna Hargett what she did over the summer, you won’t get a typical answer. She’ll tell you about her research in automatic imaging analysis of biomaterials.
Ms. Hargett and five fellow students from local high schools didn’t have ordinary summers. They spent six weeks as hands-on bioengineering researchers at the Engineering Research Center (ERC) at North Carolina A&T.
As participants in the ERC’s Young Scholars program, they worked on the center’s core projects alongside N.C. A&T professors and graduate students, as well as eight local high school and community college teachers and nine undergraduates from universities around the nation.
Details on the research teams and their projects.
Shira Chandler and Dondre McCaskill worked on the design and analysis of biodegradable magnesium screws to reconstruct knee ligaments.
For Ephraim Bililign, it was design and testing of biomedical materials, and Aditya Garg worked on corrosion testing of magnesium alloys. Aditya Badve was part of a team working on how to improve those studies.
They’re all excellent students, but when ERC researchers talk about them, another word that keeps coming up is “driven.”
“It’s big stuff that they’re working on, but they love it because they’re hanging with the big guys,” says Dr. Jagannathan Sankar, ERC director and professor of mechanical engineering.
North Carolina A&T will be involved with two significant events for researchers in August. If you’re interested in either one, now is the time to register.
- Ethical Dimensions of Coupled Natural and Human Systems Research: Monday August 13-Tuesday August 14, all day each day, Fort IRC, Room 410. N.C. A&T and Penn State faculty will conduct a this workshop for A&T faculty, post-docs, and doctoral students in the sciences and engineering who are interested in integrating the ethical dimensions of coupled natural and human systems into their classes. Registration continues through July 15.
- Nanomanufacturing conference: Wednesday, August 15, all day, at the Joint School of Nanoscience and Nanoengineering. Nanotechnology and nanomanufacturing are creating jobs in clean energy, aerospace, medicine and biotech, materials and other areas. The Nanomanufacturing Conference is one of the nation’s premier Advanced Manufacturing conferences, featuring national and international nanotech innovators, leading researchers, government leaders and visionaries.
