Pourbaix diagrams at elevated temperatures: a study of Zn and Sn
… pH, which shows the domains of various metal species and by inference, corrosion susceptibility. Elevated temperature data for tin +II and tin +IV species were obtained using solid-aqueous phase equilibria with the respective oxides, in a batch vessel with in-situ pH measurement. Solubilities, …

Synthesis of Single Isomer Trisubstituted Olefins from beta-chloro-alpha-iodo-alpha, beta-Unsaturated Esters and Alkynyl Esters
… an oxidation of palladium to form H-[Pd]-OH species. This was confirmed based on the importance of water in the catalytic system and the isotopic experiments also confirmed the olefinic hydrogen at the alpha-position arises from the water itself. Following the formation of H-[Pd]-OH, syn …

Scanning Tunneling Microscopy and Adsorption Studies on Single-Crystal Metal Oxide Surfaces
… of a Cr-O bond resulting in a freely diffusing OH species. The exchange of halogen and oxygen was studied on Cr₂O₃ (101̲2) using Auger electron spectroscopy (AES) and TDS. The exchange of chlorine and oxygen is completely reversible. Chlorine is removed from the Cr₂O₃ (101̲2) surface following …

Temperature Dependent Behavior of Optical Loss from Hydrogen Species in Optical Fibers at High Temperature
… vibrations and the combination mode of SiOH bend and stretch. The growth rate of the 1390 nm band fits the solution to the diffusion equation in cylindrical coordinates while the 2200 nm band does not. Absorption for both bands persisted as the fiber is cooled to room temperature. …

Measurement of hydrolysis, polymerization and complexation in dilute aluminum solutions
… products assuming the presence of solution species with n (OH/Al mole ratio) equal to 1, 2, 2.5, 3 and 4. The second and third hydrolysis products for Al were refined by comparison of calculated titration patterns to those observed for 10⁻³, 10⁻⁴ and 10⁻⁵ M Al in 1 M, 0.1 M and 0.01 M KCl. A …
