Local Chemistry at Interfaces and Boundaries: Ceramic and Electronic Composite Materials

The spatial extent of chemical solute distributions that formed in interfaces between platinum or silicon nitride and silicon carbide or in silicon nitride grain boundaries during high temperature processing of these composites has been investigated by position resolved nanospectroscopy, Z-contrast imaging and energy selected imaging. The solute distributions resulted from intentional sintering aid additions or interfacial reaction. The distribution widths normal to the nominal interface/boundary planes, called chemical interface/boundary widths, were much larger than the corresponding structural widths of the same boundaries and interfaces, determined by HREM imaging. Qualitative agreement between the three methods used to determine chemical widths was excellent. Differences in count rate resulting from beam current differences among the methods resulted is some predictable quantitative disagreements in absolute chemical widths. Energy selected imaging proved to be a very fast, efficient method for examination of chemical distributions over large specimen areas

Slavery and Plantation Capitalism in Louisiana's Sugar Country

Sugar planters in the antebellum South managed their estates progressively, efficiently, and with a political economy that reflected the emerging capitalist values of nineteenth-century America. By fusing economic progress and slave labor, sugar planters revolutionized the means of production and transformed the institution of slavery. Slaveholders and bondspeople redefined the parameters of paternalism and recast the master-slave relationship along a novel path. Louisiana slaves accommodated the machine, holding no torch for Luddism while concurrently shaping the agro-industrial revolution to achieve modest economic independence and relative autonomy within the plantation quarters
