The influence of interaction geometry on the obstacle strength of voids and copper precipitates in iron
TL;DR: In this paper, the authors investigated the interaction between a 1/21 1 1 1{1 1 1 0} edge dislocation and voids or coherent bcc Cu precipitates (diameter D = 2 or 4 nm) in Fe with their center displaced by ±Δz from the dislocation glide plane.

TL;DR: In this article, a study of the population of bright early-type dwarfs in the multiple-cluster system Abell 901/902 is presented, where the authors use data from the STAGES survey and COMBO-17 to investigate the relation between the color and structural properties of the dwarfs and their location in the cluster.
Journal ArticleDOI
The effects of velocities and lensing on moments of the Hubble diagram
Edward Macaulay,Tamara M. Davis,D. Scovacricchi,David Bacon,Thomas E. Collett,Robert C. Nichol +5 more
TL;DR: In this article, the dispersion on the supernova distance-redshift relation due to peculiar velocities and gravitational lensing, and the sensitivity of these effects to the amplitude of the matter power spectrum were considered.
Journal ArticleDOI
The nucleation and growth of multi-layer defects in quenched aluminium
David Bacon,R. Bullough +1 more
TL;DR: In this paper, the size effect and inhomogeneity interactions between a small dislocation loop and a vacancy were calculated and the results suggest that nucleation of a loop inside another small loop is possible without invoking a vacancy-stacking-fault interaction and once such nucleation has been achieved subsequent growth of the inner loop should take...
Journal ArticleDOI
Simulation of copper atom diffusion via the vacancy mechanism in a dilute Fe-Cu alloy
TL;DR: In this paper, the authors investigated the vacancy-copper cross-diffusion coefficient and concluded that under irradiation conditions copper atoms migrate in the direction opposite to the vacancy flux, and that about 5% of the double jumps are double jumps, when two atoms move simultaneously in a $⟨111⟩$ direction towards the vacancy.
