Reduction of AlGaAs Heterostructure High-Index-Contrast Ridge Waveguide Scattering Loss By Sidewall Smoothing Through Oxygen-Enhanced Wet Thermal Oxidation
We demonstrate the efficacy of oxidation smoothing of sidewall roughness in high-index-contrast AlGaAs heterostructure ridge waveguides via oxygen-enhanced nonselective wet thermal oxidation for reducing scattering loss.

OH Radicals and H2O2 Molecules in the Gas Phase Near to TiO2 Surfaces
The time-resolved evolution of the OH radical concentration has been observed at different pressures and at varying distances between the photocatalytic surface and the detection volume.

The Effect of Microwave-Frequency Discharge-Activated Oxygen on the Microscale Structure of Low-Temperature Water Ice Films
Low-temperature, amorphous water ice films grown by vapor deposition under high-vacuum are exposed to microwave-frequency discharge-activated oxygen in order to investigate its effect on the ice surface.

Thermochemistry of Gaseous Ammonium Nitrate, NH4NO3(g)
From the measured molecular weight of vapor over NH4NO3(c) by the simultaneous torsion-effusion/mass loss method, the partial pressure of NH4NO3(g) was evaluated over the range 321−360 K; in addition, the…
