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.
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.
Researchers from North Carolina State University have developed a novel and versatile modeling strategy to simulate polyelectrolyte systems. The model has applications for creating new materials as well as for studying polyelectrolytes, including DNA and RNA. Read More
The German Colloid Society has selected Professor Orlin Velev to give the inaugural Colloid and Polymer Science Lecture at its 2014 yearly colloquium in Mainz, Germany. The lectureship is sponsored by Springer, a global publishing company specializing in science, technical and medical (STM) fields. Their journal, “Colloid and Polymer Science,” was first published in 1906.
Ashutosh Chilkoti, the Theo Pilkington Professor of Biomedical Engineering, is one of five investigators at Duke who received $100,000 in May from the Duke Translational Research Institute (DTRI) to accelerate projects from preclinical to Phase I clinical trials.
