SEM Characterization of Proposed Hydrogen Storage Materials
EMSL Project ID
5695
Abstract
The Leo 982 field-emission SEM at EMSL will be used for microscopic and elemental characterization of sodium-aluminate alanate or similar material being studied for as a hydrogen storage medium. An inerted sample transfer device developed by EMSL SEM operator/researcher J.S. Young will be used to introduce samples of the highly air- and moisture-sensitive material into the microscope. The samples will be prepared in an inerted glovebox at PNNL and transferred to the FESEM for microstructural characterization by backscattered electron imaging and EDS elemental analysis with mapping. This work is supported by Laboratory Developmental Research (LDRD) funds and is expected to facilitate PNNL's efforts to develop a major project in the hydrogen storage material R&D. The work also includes parallel efforts to develop inerted sample transfer into JEOL 2010 TEM at EMSL, primarily in collaboration with PNNL researcher and EMSL user Alice Dohnalkova.
