We describe a first-principles-based strategy to predict the macroscopic toughness of a c-Ni(Al)/a-Al2O3 interface. Density functional theory calculations are used to ascertain energy changes upon displacing the two materials adjacent to the interface, with relaxation conducted over all atoms located within adjoining rows. Traction/displacement curves are(More)
The latest deep ultra-violet (DUV) photomask technology requires macroscopic properties such as optical transmission, reflectance, and chemical reactivity to be precisely controlled. Therefore, a fundamental understanding of the relationship between atomic bonding and nanometer scale property variation is required. Thin films of Cr-OC-N are compositionally(More)
The application of the finite-element technique to the calculation of electrostatic potentials and fields in axisymmetric containers being loaded with charged powders is illustrated. Charge accumulation during such processes can result in the onset of hazardous conditions. The electrostatic potential distributions due to some simple charge distributions are(More)
In this letter, we exploit the gravitational potential of the rich cluster A 2218 as a magnifying glass. We demonstrate that the magnification due to the cluster allows us to observe distant background galaxies at a comparable level of detail to galaxies at z ∼ 0.1. Using the GMOS Integral Field Unit on Gemini North we observed the spatially-resolved(More)
We present the first results from a new and unique integralfield spectrograph, SAURON. Based upon the TIGER concept, SAURON uses a lens array to obtain two-dimensional spectroscopy with complete spatial coverage over a field of 33 × 41 in low-resolution mode (0. 94 lenslets) and of 9 × 11 in high-resolution mode (0. 26 lenslets). The spectra cover the(More)
