Cyclic Oxidation of Iron Aluminides

CORROSION 1993, 1993
Abstract Iron aluminides containing 16 to 28 at.% Al and other more minor alloying elements were subjected to air oxidation under moderate thermal cycling conditions. Aluminides with 16 at.% Al and additions of chromium (5%) and zirconium (0.1%) were superior to binary alloys of 16 and 20% Al in oxidation resistance at 900 and 1000°C and

Nitric oxide and the other cyclic nucleotide

Cellular Signalling, 2002
Nitric oxide (NO) participates in the regulation of the daily activities of cells as well as in cytotoxic events. Elucidating the mechanism(s) by which NO carries out its diverse functions has been the goal of numerous laboratories. In the cardiovascular system, evidence indicates that NO mediates its effects via an activation of soluble guanylyl ...

Computer Simulation of Cyclic Oxidation

JOM, 1988
A computer program has been developed which simulates the cyclic oxidation behavior of materials. The simulation is based on the assumption that the weight fraction of scale that spalls in any thermal cycle is proportional to the amount of scale present on the surface at the beginning of the cycle.

Oxidative Kinetic Resolution of Cyclic Benzylic Ethers

Angewandte Chemie International Edition, 2020
AbstractA manganese‐catalyzed oxidative kinetic resolution of cyclic benzylic ethers through asymmetric C(sp3)−H oxidation is reported. The practical approach is applicable to a wide range of 1,3‐dihydroisobenzofurans bearing diverse functional groups and substituent patterns at the α position with extremely efficient enantiodiscrimination.

Copper-catalyzed oxidation of arene-fused cyclic amines to cyclic imides

Chemical Communications, 2013
A novel copper-catalyzed oxidation of arene-fused cyclic amines to the corresponding cyclic imides has been developed. The reaction can be used to synthesize 1,3-disubstituted TPD in high yields.

The Cyclic Oxidation behavior of Oxide-Dispersed β-NiAl

MRS Proceedings, 1994
AbstractShort-term cyclic oxidation tests were performed at 1200°C and 1500°C on ²-NiAl with 1 vol% oxide dispersions of Y2O3, La2O3 and Al2O3. The Y2O3 addition resulted in a very adherent ±-Al2O3 scale at 1200°C, with some improvement in the scale adhesion at 1500°C, compared to an undoped ²-NiAl alloy.

Analysis on failures of protective-oxide layers and cyclic oxidation

Oxidation of Metals, 1993
A condition of oxide-scale spalling is derived from the concept of strain energy proposed by Evans. By considering the probabilistic distribution of fracture strain energy across the metal oxide interface, the fraction of oxide scale spalled is described as a function of the weight of oxide before cooling and temperature change.

Electrochemical oxidation of cyclic polysilanes

Journal of Organometallic Chemistry, 2003
Abstract During the past decade, the electrochemical properties of cyclic polysilane derivatives, namely [Mes2Si]3 (I), [t-Bu(Me)Si]4 (IIa), [Et2Si]4 (IIb), [(n-Pr)2Si]5 (IIIa), [Et2Si]5 (IIIb), [Me2Si]6 (IVa), [Et2Si]6 (IVb), [Et2Si]7 (V), [Me2Si]8 (VI), and [Me2Si]9 (VII), have been explored in our laboratory.

Novel Cyclic Ketones for Catalytic Oxidation Reactions

The Journal of Organic Chemistry, 1998
In our effort to search for C2 symmetric and conformationally rigid chiral ketones as catalysts for asymmetric epoxidation, a series of cyclic ketones 4−10 were prepared from the corresponding diacids. Compared with acyclic ketones for epoxidation of trans-stilbene, those 9-, 10-, and 11-membered-ring cyclic ketones were found to have much higher ...
