Abstract

We present laboratory studies of the radiolysis of pure (97%) solid H{sub 2}O{sub 2} films by 50 keV H{sup +} at 17 K. Using UV-visible and infrared reflectance spectroscopies, a quartz-crystal microbalance, and a mass spectrometer, we measured the absolute concentrations of the H{sub 2}O, O{sub 2}, H{sub 2}O{sub 2}, and O{sub 3} products as a function of irradiation fluence. Ozone was identified by both UV and infrared spectroscopies and O{sub 2} from its forbidden transition in the infrared at 1550 cm{sup -1}. From the measurements we derive radiation yields, which we find to be particularly high for the decomposition of hydrogen peroxide; this can be explained by the occurrence of a chemical chain reaction.

Indium Oxide Thin Films by Atomic Layer Deposition Using Trimethylindium and Ozone

Journal Article Mane, Anil; Allen, Amy; Kanjolia, Ravindra; ... - Journal of Physical Chemistry. C

We investigated the atomic layer deposition (ALD) of indium oxide (In2O3) thin films using alternating exposures of trimethylindium (TMIn) and a variety of oxygen sources: ozone (O-3), O-2, deionized H2O, and hydrogen peroxide (H2O2). We used in situ quartz crystal microbalance measurements to evaluate the effectiveness of the different oxygen sources and found that only O-3 yielded viable and sustained 111203 growth with TMIn. These measurements also provided details about the In2O3 growth mechanism and enabled us to verify that both the TMIn and O-3 surface reactions were self-limiting. In2O3 thin films were prepared and characterized using X-ray diffraction, ultravioletmore »« less

Decomposition of hydrogen peroxide at elevated temperatures

Technical Report Lin, C; Smith, F

Decomposition of hydrogen peroxide in high-purity water has been measured at temperatures ranging from 100 to 280{degree}C in a laboratory test loop. A first-order decomposition kinetics has been observed in all cases, but the decomposition rates were found to vary widely, depending on the material used in the reaction chamber. In a 1/4 inch OD stainless steel tubing, the decomposition rate constant is estimated at 0.3 sec{sup {minus}1} at 280{degree}C and the activation energy is 15 Kcal/mol. This decomposition rate is approximately 100 times faster than that observed in a Teflon tubing. The variation of decomposition rate in different reactionmore »« less
Stability of Solid Uranyl Peroxides under Irradiation

Journal Article Fairley, Melissa; Myers, Nicholas; Szymanowski, Jennifer; ... - Inorganic Chemistry

The effects of radiation on a variety of uranyl peroxide compounds were examined using γ-rays and 5 MeV He ions, the latter to simulate α-particles. The studied materials were studtite, [(UO₂)(O₂)(H₂O)2](H₂O)₂, the salt of the U₆₀ uranyl peroxide cage cluster, Li₄₄K₁₆[(UO₂)(O₂)(OH)]₆₀·255H₂O, the salt of U₆₀Ox₃₀ uranyl peroxide oxalate cage cluster, Li₁₂K₄₈[{(UO₂)(O₂)}₆₀(C₂O₄)₃₀]·$$n$$H₂O, and the salt of the U₂₄Pp₁₂ (Pp = pyrophosphate) uranyl peroxide pyrophosphate cage cluster, Li₂₄Na₂₄[(UO₂)₂₄(O₂)₂₄(P2O7)12]·120H₂O. Irradiated powders were characterized using powder X-ray diffraction, Raman spectroscopy, infrared spectroscopy, X-ray photoelectron spectroscopy, and UV–vis spectroscopy. A weakening of the uranyl bonds of U60 was found while studtite, U₆₀Ox₃₀, and U₂₄Pp₁₂ weremore »« less

Photolysis of solid NH{sub 3} and NH{sub 3}-H{sub 2}O mixtures at 193 nm

Journal Article Loeffler, M; Baragiola, R - Journal of Chemical Physics

We have studied UV photolysis of solid ammonia and ammonia-dihydrate samples at 40 K, using infrared spectroscopy, mass spectrometry, and microgravimetry. We have shown that in the pure NH{sub 3} sample, the main species ejected are NH{sub 3}, H{sub 2}, and N{sub 2}, where the hydrogen and nitrogen increase with laser fluence. This increase in N{sub 2} ejection with laser fluence explains the increase in mass loss rate detected by a microbalance. In contrast, for the ammonia-water mixture, we see very weak signals of H{sub 2} and N{sub 2} in the mass spectrometer, consistent with the very small mass lossmore »« less

Radiation chemistry in ammonia-water ices

Journal Article Loeffler, M; Raut, U; Baragiola, R - Journal of Chemical Physics

We studied the effects of 100 keV proton irradiation on films of ammonia-water mixtures between 20 and 120 K. Irradiation destroys ammonia, leading to the formation and trapping of H{sub 2}, N{sub 2}, NO, and N{sub 2}O, the formation of cavities containing radiolytic gases, and ejection of molecules by sputtering. Using infrared spectroscopy, we show that at all temperatures the destruction of ammonia is substantial, but at higher temperatures (120 K), it is nearly complete ({approx}97% destroyed) after a fluence of 10{sup 16} ions/cm{sup 2}. Using mass spectroscopy and microbalance gravimetry, we measure the sputtering yield of our sample andmore »« less
