Surface-analytical Studies on Environmental and Geochemical Surface Processes

Surface Crystal Chemistry of Phyllosilicates Using X-Ray Photoelectron Spectroscopy: A Review

“…Innovative research on mineral surfaces has generated a better understanding of environmentally related aspects and promising industrial process applications. In addition, a better characterization and understanding of Earth material surface properties has been of fundamental importance to mineralogy, geochemistry, solid-state physics, biology, chemistry, and material science, as well as for pharmaceutical and cosmetic applications (Hochella, 1990(Hochella, , 1995Seyama and Soma, 2003;Carretero andPozo, 2009, 2010;Maurice, 2009;Somorjai and Li, 2011).…”

X‐ray photoelectron microscopic imaging of the chemical bonding state of Si in a rock sample

“…during chemical weathering, resulting in the formation of new mineral phases on the surface. 1 Hence, the chemical bonding state of Si in the surface layer of minerals is an important indication of weathering conditions and mechanisms. To evaluate the utility of imaging XPS in mineralogical and petrological chemistry, we applied chemical-bonding-state imaging for Si to a rock sample.…”

Characterization of pebble surfaces coated with biogenic manganese oxides by SIMS, XPS and SEM

“…That is, chemical interactions between a solid and its environment are governed by the chemical composition of the surface of the solid rather than by its bulk composition. Therefore, examining the surfaces of environmental and geological solid samples in detail is important [10,11]. As shown in this study, a combination of surface-analytical techniques such as SIMS and XPS is especially advantageous for the characterization of the surfaces of environmental samples with intricate microstructures.…”
