The reactivity of the hydroperoxo complex [Co(CN)(5)OOH](3)(-) has been studied in aqueous solution. The complex undergoes acid-catalyzed aquation (k = 1.89(5) x 10(-)(2) s(-)(1), pK(a) = 5.21(4), T = 20 degrees C, I = 0.1 M). Assuming an I(d) mechanism, this allows the relative affinity for Co(III) to be deduced as H…

The photoelectrochemical properties of π-conjugated poly(3-hexylthiophene) films in aqueous solution are presented. Application of potential biases more negative than +0.3 V (SCE) to the polymer film immersed in an aqueous electrolyte gives rise to a depletion layer at the polymer/solution interface. Photoexcitation o…

The influence of alloying levels in the range (in mass%) of 0.01-0.5 nitrogen and 0.2-10 manganese on pitting corrosion resistance has been investigated for austenitic stainless steels with a base composition (in mass%) of 20Cr-18Ni-4.5Mo. The beneficial effect of nitrogen alloying is confirmed, while the detrimental…

High-yield mullite (3Al 2 O 3 −2SiO 2 ) precursors consist of aluminosiloxanes synthesized from mixtures of aluminum and silicon alkoxides. Atomic level mixing of the aluminum and silicon oxides is demonstrated by the low-temperature conversion (<1000 °C) of the aluminosiloxanes to phase-pure mullite. The proper selec…

We devise a constraint algorithm that makes the angular velocity of the director of a liquid crystal a constant of motion. When the angular velocity is set equal to zero, a director based coordinate system becomes an inertial frame. This is a great advantage because most thermodynamic properties and time correlation f…

The first steps of silver clusters nucleation have been studied by pulse radiolysis in the presence of EDTA and CN - ligands. The successive rate constants and the transient absorption spectra corresponding to Ag 1 0 and Ag 2 + have been determined. It has been found that Ag 1 0 and Ag 2 + were complexed by the ligand…

In a calcareous sinter precipitated from cold saline spring water at Shiowakka, Hokkaido, Japan, ikaite (CaCO3·6H2O) was found in winter, subsequent to the finding of monohydrocalcite with calcite in the previous summer. The formation of the ikaite was favored by low temperature, while that of the monohydrocalcite was…

Gold oxide films were prepared by reactive sputtering of pure gold in an oxygen plasma. These films were characterized by chemical and physical means to better understand the behavior of this metastable compound. Gold oxide, Au2O3, decomposes into the elements at 350 °C. It does not react with dry carbon dioxide but d…

Laboratory corrosion tests have always been an important tool for Zr alloy development and optimization. However, it must be known whether a test is representative for the application in-reactor. To shed more light on this question, coupons of several Zr alloys were exposed under isothermal conditions in all or most o…
