Abstract

A fundamental property of all matters is that they change phases as temperature changes. The researches on phase changes from solid to liquid and from liquid to gas had built the foundation of thermodynamics. After that, the concept of phase change has been constantly important in college textbook, but the research on phase change materials has never become an active area again.

We have explored the unique thermal properties of nanoscale phase change materials (i.e., nanopcm) for a number of applications in biomedical, energy and security fields. These properties include large latent heat of fusion, sharp melting peaks, rapid melting, super-cooling, composition-dependent melting temperature, and eutectic solid formation. Specifically, we are working on following projects. (1) We use nanopcms with suitable melting temperatures to enhance heat transfer ability of fluids (both liquid and vapor). (2) We use a selected panel of nanpcms as reporters to detect multiple biomarkers for the early diagnosis of disease. (3) We use a series of nanopcms with discrete melting peaks as barcodes to label a variety of objects for anti-counterfeiting, forensic and security applications.

 

Biography

Dr. Ming Su is an associate professor at Department of Chemical Engineering at Northeastern University. His research is focused on nanomaterials especially thermal nanomaterials, and nanomedicine. His research has been supported by NSF, NIH, DOJ, DOD, and AFRL.

Dr. Ming Su received his BS degree from Northwest University, MS degree from Nankai University and PhD degree from Chinese Academy of Science and Northwestern University. He joined Oak Ridge National Laboratory as a Eugene P Wigner Fellow and research staff in 2004. He was an assistant professor and associate professor at University of Central Florida and Worcester Polytechnic Institute. He is now an associate professor at Department of Chemical Engineering at Northeastern University. He has created an inter-disciplinary research and education team focusing on nanomedicines, where nanoparticles are used to detect multiplex biomarkers of diseases, to remove heat generated in biological system, to enhance radiation therapy, and to find out fake drugs. In particular, his group has pioneered the use of solid-to-liquid phase change nanoparticles for hot spot cooling, biosensing, and high capacity labeling. He has received many prestigious and highly competitive awards including ACS-PRF Doctoral New Investigator Award (2007), DOD Concept Award (2010), NSF Career Award (2011), NIH Director’s New Innovator Award (2012), DOJ New Investigator Award (2012), , and most recently a JALA 2013 Breakthrough in Innovation Award.
