IACChE's James Y. Oldshue Lecture

Tuesday, November 12, 2019,
8:00am to 10:30am
EST

This lecture was jointly established, in 2008, in memory of James Y. Oldshue by the American Institute of Chemical Engineers (AIChE) and the Interamerican Confederation of Chemical Engineering (CIIQ/IACChE). Jim Oldshue was an important leader and supporter of the CIIQ/IACChE.  He was President of the AIChE in 1979 and President of the CIIQ/IACChE in 1995.  Jim was a recipient of the prestigious Víctor Márquez award in 1983, which is conferred by the CIIQ/IACChE. Jim was an ambassador of the profession who visited more than 100 countries.  It is envisioned that this lecture provide a global perspective of a specific contingent topic.  The Oldshue Lecture alternates between the AIChE Annual Meetings and the Interamerican Congresses, which take place every two years.

This year's distinguished lecturer is Dr. Carlos Rinaldi, Chair and Professor, University of Florida. Dr. Rinaldi will deliver his lecture at the 2019 AIChE Annual Meeting.

Response of Magnetic Nanoparticles to Time Varying Magnetic Fields: Ferrohydrodynamics, Nanoscale Thermal Therapy, and Magnetic Particle Imaging

Dr. Carlos Rinaldi, Department of Chemical Engineering and J. Crayton Pruitt Family Department of Biomedical Engineering, University of Florida

Colloidal suspensions of magnetic nanoparticles are fascinating from an intellectual and practical perspective because of their behavior in externally applied static and dynamic magnetic fields. This includes particle translation in magnetic field gradients, internal dipole or whole-particle rotation when the local magnetic field changes direction, and dissipation of magnetic field energy in the form of heat, among others. Suspensions of magnetic nanoparticles in Newtonian fluids, commonly known as ferrofluids, have been of interest since the 1960’s due to their practical applications and unique fluid mechanics. More recently, biomedical applications of magnetic nanoparticles have been of great interest. Magnetic nanoparticles have been clinically translated for use as magnetic resonance imaging contrast agents, in sentinel lymph node detection, and in nanoscale thermal therapy for cancer. Furthermore, the nonlinear magnetization response of superparamagnetic iron oxide nanoparticle tracers is critical for magnetic particle imaging, a new molecular imaging modality that allows for non-invasive, tomographic, unambiguous, and quantitative imaging of tracer distribution. This talk will focus on the response of magnetic nanoparticles to applied time varying magnetic fields. First, the phenomenological description of ferrofluid flows in rotating magnetic fields will be presented, along with theoretical and experimental work suggesting the existence of antisymmetric and couple stresses, features of structured fluid continua. Second, experimental evidence will be presented in support of nanoscale thermal phenomena in the vicinity of magnetic nanoparticles, resulting in lysosomal permeabilization and death in cancer cells without a macroscopic temperature rise. Third, magnetic particle imaging guided nanoscale thermal therapy will be presented, along with recent results demonstrating unprecedented spatial resolution imaging using strongly interacting magnetic particle imaging tracers.
