Creating large amounts of polymer nanofibers dispersed in liquid is a challenge that has vexed researchers for years. But engineers and researchers at North Carolina State University and one of its start-up companies have now reported a method that can produce unprecedented amounts of polymer nanofibers, which have potential applications in filtration, batteries and cell scaffolding.

In a paper published online in Advanced Materials, the NC State researchers and colleagues from industry, including NC State start-up company Xanofi, describe the method that allows them to fabricate polymer nanofibers on a massive scale. Read More

Abstract A simple process for batch or continuous formation of polymer nanofibers and other nanomaterials in the bulk of a sheared fluid medium is introduced. The process could be of high value to commercial nanotechnology as it can be easily scaled up to the fabrication of staple nanofibers at rates that could exceed tens of kilograms per hour.

Researchers have fine-tuned a technique for coating gold nanorods with silica shells, allowing engineers to create large quantities of the nanorods and giving them more control over the thickness of the shell. Gold nanorods are being investigated for use in a wide variety of biomedical applications, and this advance paves the way for more stable gold nanorods and for chemically functionalizing the surface of the shells.

Gold nanorods have a lot of potential applications, because they have a surface plasmon resonance - meaning they can absorb and scatter light. And by controlling the dimensions of the nanorods, specifically their aspect ratio (or length divided by width), you can control the wavelength of light they absorb. Read More

In a recent study published in Soft Matter, Benjamin Yellen, associate professor of mechanical engineering and materials science at Duke University, and his colleagues, Josh Socolar and Patrick Charbonneau in Duke’s physics and chemistry departments, respectively, use a single layer of microscopic colloidal particles suspended in a thin liquid medium to watch phase transitions in action.

The Research Triangle MRSEC (RT-MRSEC) Industry Poster Symposium workshop took place in the Hunt library on NC State’s Centennial Campus on Feb 12, 2015.  The goal of the symposium was to build bridges between academia and industry through an open forum between participating industrial panel members and the RT-MRSEC community.  In addition, there was a poster presentation by RT-MRSEC graduate students that allowed them to showcase their research to the panelists.  The RT-MRSEC leadership invited hosted four industrial panel members who have collaborated in the past with various academic institutions and were thus familiar with the way we conduct research in universities.  The members of the industrial board were: Dr. Andrea Liebmann-Vinson, Director of BioSense, Becton Dickinson Technologies, Dr. Barclay Satterfield, Sr. Chemical Engineer, Eastman Innovation Ctr, Eastman Chemical Company, Dr. Damon R. Billodeaux, Visiting Scientist, Eastman Innovation Ctr, Eastman Chemical Company, and Dr. Timothy D. Fornes, Senior Staff Scientist, Chemical Research, Lord Corporation.

The symposium consisted of two sessions.  In the first session, an open Q&A forum, the industry panelists provided basic insight into how industry operates, and outlined expectations (technical skills, professional development, team work, etc.) that are expected of new industry hires.  The most important issues discussed during the forum included differences between industry and academia aspirations / careers; the skills private sector companies look for when recruiting; and how a PhD student might approach industry to seek employment. Students were advised to practice good communications skills, presentation of work/research, development of interdisciplinary and team-work skills, not be afraid to ask questions and to be succinct and right-to-the-point when communicating your ideas. The second session included a poster presentation by the RT-MRSEC graduate students which enabled them to communicate their own research to their colleagues, members of the industrial panel, as well as faculty members present at the event.
