Site specific atomic resolution chemical imaging to probe structure-property relationship under dynamic and/or operando conditions using in-situ and ex-situ methods based on multi-instrument approach
EMSL Project ID
46696
Abstract
The goal of this proposal is to develop chemical imaging capabilities that drive the atomic-level imaging and spectroscopic analysis of materials related to energy and environmental issues under in-situ/operando condition and lead to the development of much-needed materials for next-generation energy and environment-related applications. This will be achieved by extending the state-of-the-art aberration-corrected scanning transmission electron microscopy/transmission electron microscopy (STEM/TEM) and other complementary microscopy and spectroscopic imaging capabilities to a new level, enabling atomic-resolution imaging and spectroscopic analysis under dynamic operating conditions. Further, new capabilities will be developed to enable complementary integration of site-specific atomic resolution structural and chemical information obtained from various techniques, including STEM/TEM, atom probe tomography (APT), and focused ion beam and scanning electron microscopy (FIB/SEM).
