Kinetic studies of chromium (VI) binding to carboxylic acid- and methyl ester-functionalized silica/water interfaces important in geochemistry
Article Abstract:
Real-time kinetic measurements of hexavalent chromium binding to fused silica surfaces functionalized with carboxylic acid and methyl ester terminal groups are done in situ using resonantly enhanced surface second harmonic generation (SHG) at pH 7 and 300 K. The results indicate that hexavalent chromium mobility in carboxylic acid- and ester-rich soil environments increases with decreasing chromate concentrations.

Carboxylic acid- and ester-functionalized siloxane scaffolds on glass studied by broadband sum frequency generation
Article Abstract:
Broadband sum frequency generation is used to characterize glass surfaces functionalized with siloxanes containing terminal carboxylic acid and ester functional groups. Omega-ester silanes can be used in the preparations of ester-functionalized glass surfaces, which yield acid-functionalized surfaces via hydrolysis.
