Acquisition of a suite of 3D EDX tomography and in situ heating and straining TEM holders to probe the response of nanomaterials
Abstract
ABSTRACT: (Publically releasable)This proposal requests the acquisition of a suite of 3D tomography and in situ transmission electron microscopy (TEM) holder systems. The unique capabilities of the requested new holder systems include: (1) 3D energy dispersive x-ray (EDX) tomography enabled by the proposed tomography holders and existing FEI Talos 200X with super EDX will achieve comprehensive 3D view of chemical inhomogeneity due to phase segregation at high resolution. (2) The in situ straining holder system can probe deformation mechanisms and crack propagation under tension. (3) The in situ heating holders can be used investigate high temperature" response of materials up to 1,000-1,300oC. The 3D EDX tomography holder and in situ TEM holder systems with heating and tensile tes"ting capabilities will address urgent needs for (i) conducting the fundamental research projects on microstructure and chemistry evo"lution of ceramics and metallic nanocomposites fabricated by sintering process, and probe their mechanical behavior under tension at"" Purdue University, which are currently funded by the Office of Naval Research (N00014-13-1-0555 and N00014-16-1-2778); (ii) establi"shing new research capabilities in the areas of nanocomposites and nanoscale characterizations on campus; (iii) providing hands-on experiences on in situ manipulation and characterizations to graduate and undergraduate students; and (4) assisting the classroom teaching and outreach programs by providing demo sessions and videos of in situ TEM experiments on nanomaterials to a larger number of undergraduates and graduates at Purdue University and a much broader audience.
