News & Announcements

Durham, NC-based Sentilus is led by Prof. Ashutosh Chilkoti, Chair of the Department of Biomedical Engineering and Director of the Center for Biologically Inspired Materials and Material Systems at Duke University, and co-founder and CEO Angus Hucknall. Sentilus was formed in 2012 with the goal of developing applications of a non-fouling surface coating developed by Prof. Chilkoti. Sentilus's primary commercialization efforts have focused on the use of this coating technology for clinical diagnostics, based on Mr. Hucknall's doctoral research with Prof. Chilkoti.

"We are excited to be teaming up with Immucor to advance the development of our proprietary technology," stated Dr. Chilkoti. "With Immucor's focus on ensuring transfusion and transplantation safety, we are excited to join forces with them to bring our novel microarray-based technology to the market."

Abstract: We present a method to control the interfacial energy of a liquid metal via electrochemical deposition (or removal) of an oxide layer on its surface. Unlike conventional surfactants, this approach can tune the interfacial tension of a metal significantly (from ∼7× that of water to near zero), rapidly, and reversibly using only modest voltages. These properties can be harnessed to induce previously unidentified electrohydrodynamic phenomena for manipulating liquid metal alloys based on gallium, which may enable shape-reconfigurable metallic components in electronic, electromagnetic, and microfluidic devices without the use of toxic mercury. The results also suggest that oxides—which are ubiquitous on most metals and semiconductors—may be harnessed to lower interfacial energy between dissimilar materials.

Koohee Han, NCSU, led the team to win Best Poster Award. Congratulations to Koohee and all collaborators, including Wyatt Shields, Duke University, Bharti Bhuvnesh, NCSU & Nidhi Diwakar, Worchester Polytechnic Institute. In addition, Jessica Nash and Nan Li, RT-MRSEC students from NCSU, also received awards in this category. The students in this category study under Drs. Yara Yingling, Orlin Velev & Gabriel Lopez.

In the Technology Innovation Forum, the Grand Prize Winner was Vrad Levering, Duke University. Vrad studies under Dr. Gabriel Lopez. The grand prize includes a full-paid trip to the Fall Materials Research Society Meeting & Exhibit in Boston, MA where Vrad will showcase his demonstration.

Research Triangle MRSEC also offered up a special category within the technology innovation forum and poster session as each relates specifically to soft matter. The first place winner for technology innovation was Phanindhar Shivapooja, Duke University. The second place winners in the poster competition were Wei-Chen (Ivy) Wu & Bryan Anderson, North Carolina State University.

The Triangle Student Research Competition (TSRC) is an event organized by local student chapters from the Materials Research Society (MRS) and the Electrochemical Society (ECS) from area universities – including NCSU, UNC-Chapel Hill, Duke University, NC A&T, and NCCU – with the assistance of various co-sponsors from throughout the region. The main purpose of this event is to bring together researchers from throughout the NC Triangle region to network and share their exciting research with other researchers and companies.

Professor Carol Hall has been selected to receive the 2015 Foundations of Molecular Modeling and Simulation (FOMMS) Medal. The Medal recognizes Carol's many contributions to the field of molecular theory, modeling, and simulation, including theoretical treatments for phase separations in colloidal suspensions, theory and simulation methods for off-lattice models of polymers, and molecular modeling and simulations that have advanced understanding of the dynamics of protein-protein aggregation. 

Carol will receive the Medal and deliver the capstone lecture at the 2015 Conference on Foundations of Molecular Modeling and Simulation, July 12-16, 2015.

Congratulations, Carol, on receiving the 2015 FOMMS Medal! The recognition of your accomplishments is well deserved.
