Single crystals of stoichiometric MgA1204 spine1 were neutron-irradiated to fluences (> 0.1 MeV) of 2.8 x loz5 n m-2 (1.5 dpa) at 1015 K and 1.9 x loz6 n m-2 (10 dpa) at 925 K and 1 100 K. The resulting point defect'aggregates were investigated using bright-field and weak-beam dark-field transmission electron microscopy. For the higher dose, faulted interstitial Frank dislocation loops were fou...

This paper investigates the role of stacking fault (5%, 20% and 50%) morphology Li2MnO3 lamellar materials, issued from coprecipitation method with three annealing temperatures, on surface reactivity. The structure have been characterized by XRD, SEM TEM. We studied reactivity these materials combining X-ray photoemission spectroscopy (XPS), gaseous adsorption first-principle calculations. An e...

ZnSe nanospirals including structures with polarity continuation and polarity frustration are simultaneously observed at atomic resolution. Through careful analysis of polarity within each dumbbell based on aberration-corrected high-angle annular-dark-field imaging, polarity continuation across parallel polytype interfaces as well as the surrounding Z-shape faulted dipoles is verified. Moreover...

We describe a system for generating accurate tests for bridge faults (with or without feedback) in CMOS ICs. We present the Test Guarantee Theorem, which allows for accurate test generation for feedback bridge faults via topological analysis of the feedbackin uenced region of the faulted circuit (without the need for any post-test veri cation or explicit examination of inversion parity). We des...
