Bio Upon graduating from Bucharest University, Theodorian Borca-Tasciuc spent several months as a research assistant for The Institute of Physics and Technology of Radiation Devices, also located in Bucharest. He joined Duke University's Department of Mechanical Engineering and Materials Science for over a year as a graduate student research assistant before beginning work on his doctorate at UCLA (PhD 2000).

Dr. Theodorian Borca-Tasciuc has started his academic career in 2001 at Rensselaer Polytechnic Institute and since 2007 he is an associate professor. He is the director of the Nanoscale Thermophysics and Energy Conversion Laboratory (NanoTEC) on the Rensselaer campus. He received the NSF CAREER award (2004), is an associate editor for the Journal of Nanomaterials, and a member of the ASME’s K8 committee on Fundamentals of Heat Transfer. He has organized and chaired symposia and sessions on nanoscale thermal transport and energy conversion with ASME and MRS.

Research Description

The main research theme in the Nanoscale Thermophysics and Energy Conversion(NanoTEC) laboratory directed by Dr. Theodorian Borca-Tasciuc is engineering nanoscale thermal transport and thermoelectric energy conversion. His work focuses on experimental investigations in synergy with physical models and materials structure. Features in the investigated samples (thin films, nanoparticles, nanowires, or the nano-domains in nanomaterials) are typically smaller than characteristic length scales of the heat carriers (such as the carrier mean free path), so conduction of heat can strongly deviate from the classical Fourier law. Similarly, nanoscale heat sources could also exhibit non-classical conduction of heat. These are critical issues for the thermal management of nanodevices, nanointerconnects, optoelectronics, or the design of nanocomposites and nanomaterials.
On another hand, nanostructures and nanostructured materials enable novel ways to independently control the thermoelectric properties (Seebeck coefficient and electrical and thermal conductivities) that define the thermoelectric figure of merit Z, a metric important for thermoelectric energy conversion applications ( such as solid state refrigeration and power generation). The enhancement of Z in nanostructures is mainly effected through control of size, interfaces, and doping in the material. The goal is to obtain non-dimensional figures of merit (ZT, T is temperature) that increase to values as high as 1.5-3, from the current values <1, to revolutionize solid state thermoelectric applications for cooling and power generation from waste heat.

Understanding and engineering the thermal and thermoelectric transport at nanoscale is therefore an essential and challenging part of Dr. T. Borca-Tasciuc’s research. A critical role is played by development of experimental techniques able to probe transport properties at nanoscale, in nanomaterials, across-nanointerfaces, or to test the operation of nanoscale thermoelectric devices. These techniques are employed to perform studies of property-structure relationship to understand and optimize thermal and thermoelectric transport as required by specific applications. Selected examples of techniques developed include a scanning thermal microprobe for quantitative characterization of the thermal conductivity and Seebeck coefficient with microscale resolution, a transient method for measurement of all thermoelectric properties as well as electrical and thermal contact resistances in films, a photothermoelectric method to determine the anisotropic thermal conductivity and the interface thermal resistance in thin film on-substrate systems, a Joule heating thermometry method for characterization of thermal transport from nanoscale heat sources.

Selected investigations include: 1) discovery of a new class of highly scalable, high figure of merit, nanostructured bulk thermoelectric materials (patent pending); 2) implementation of a novel mechanism for formation of high thermal conductivity networks in polymer composites filled with nanoparticles (patent pending); 3)investigations of anisotropic thermal properties in aligned carbon nanotube arrays and aligned carbon-nanotube polymer composites; 4) studies of the interface thermal resistance at the native interface between carbon nanotube arrays and the silicon substrate; 5) investigations of thermal transport in Si/Ge and Si/SiC multilayers; 6) investigations of non-Fourier thermal transport from individual nanoscale heaters to silicon substrates;

Bio Career Highlights:
Upon earning his Ph.D. with Tim Lodge at the University of Minnesota , Dr. Ryu served as a postdoctoral researcher with Ed Kramer and Glenn Fredrickson at the University of California , Santa Barbara for nearly two years. He joined Rensselaer in November, 2000 as an assistant professor of chemistry,and was promoted to an Associate Professor in 2006. He has won the NSF CAREER Award (2005), Mettler-Toledo Thermal Analysis Education Grant (2001), the Arthur K. Doolittle Award from the American Chemical Society Division of Polymeric Materials Science and Engineering (1998), and Korea Foundation for Advanced Studies Scholarship (1993 – 1998).

Research Areas:
Macromolecular Separation and Adsorption:
Our group is studying macromolecular separation and adsorption using high performance liquid chromatography (HPLC). We study polymer separation by HPLC and explore its unique applications for rigorous analysis and purification of polymers, block copolymers and functional oligomers. We also pursue a molecular level understanding of polymer/copolymer adsorption in confined geometries in order to gain insights on macromolecular interactions during HPLC. We are mainly interested in separating (co)polymers and oligomers that are synthetically very challenging to obtain as pure samples and/or can have technological implications in nanoscale self-assembly, electro-optical applications, and carbon nanotube fabrication.

Block Copolymer Self-Assembly in Solution and Thin Films:
We are interested in developing a polymer research program in structure-property relationships of multiphase polymer systems, where their performance and applications are closely related to the mesoscopic morphologies. The central theme of my research effort will be the design, synthesis, and characterization of model polymers and the study of their structure-property relationships as in bulk and thin films. We will combine the polymer separation technique using HPLC to obtain pure block copolymers and study their self-assembly in solution and thin films. The ultimate aim will be to guide the rational design of polymeric materials, thus gaining a fundamental understanding in the correlation between properties and structures in multiphase polymers.
