Nancy Yang

Energy Nanomaterial Sciences Department, 
Sandia National Laboratories, California (SNL/CA)


As a DOE funded R&D laboratory, we are actively engaged in multiple fronts of science and technology (S&T) related to energy applications. Many of these programs can be applied to defense as well as civilian use. In this talk, I will describe the energy programs and missions at the Sandia CA. These programs include material development for hydrogen storage and S&T advancement in thermoelectric power generation. For the thermoelectric (TE) power generation, I will present and discuss the material science issues encountered for Bi2Te3-based TE system and its implication to power generation efficiency.

Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.


Nancy is a material scientist with extensive experience and expertise in electron optics (EO) applications. She is currently a team leader of the Electron Optical (EO) instrumentation group and play a dual technical roles at SNL/CA. She has been the Principal Investigators for many research projects such as Bi-Te thermal electric system, Nanocrystalline Aluminum R&D, Alloy Synthesis Technology, LIGA microsystem and Corrosion resistance material R&D for Yucca Mountain Project. Nancy has presented more than 100 significant findings from these diverse research projects in professional conferences, meetings and journals and five patents. In addition to the R&D role, Nancy also is responsible for providing site-wide support of material characterization using electron optics (EO) analyses at SNL, CA. She supervises four full time technical staff and postdoctoral employee and oversees four microscopy laboratories, which includes optical metallography (OM), scanning electron microscopy (SEM), analytical electron microprobe analyses (EMPA) and transmission electron microscopy (TEM). She provides consultation, designs and develops experimental procedures, conducts material characterization and supervises the team to carry out the analyses for researchers at SNL/CA.  She is ultimately responsible for the quality of the scientific data and interpretations of the results. The EO group and facility operations delivers more than 400 technical requests annually site-wide at SNL, CA. Many of the scientific contribution at SNL impact the program direction

Including SNL, Nancy has 30 years of experience in materials R&D, electron optical applications, and facility operations from a wide range of industries and institutions, including University of Pennsylvania, GE Nuclear Power Division and Kaiser Aluminum Co. Nancy’s R&D activities has gone beyond Sandia. She collaborate extensively with scientist in many institutions, e.g. Lawrence Livermore Laboratory, and University of California, Davis, In addition to her critical technical roles.
