Mineral inclusions in Sao Luiz diamonds have been characterized using angle dispersive X-ray diffraction and Raman spectroscopy. We identified two different garnet phases coexisting with an omphacitic pyroxene. They represent disintegration products of a f ...
The crack growth across a boundary between two colonies, i.e. regions of differing lamellar orientation, in two-phase lamellar Ti-Al is studied computationally to quantify the influence of such boundaries on toughening, as observed in recent in-situ fractu ...
Nanobacteria-like objects evidenced at the surface of the orthopy-roxenes of the Tataouine meteorite in South Tunisia have been studied by scanning and transmission electron microscopies. A method of micromanipulation has been developed to ensure that exac ...
Molecular statics simulations of crack growth in fully lamellar Ti-Al are performed to elucidate the role of lamellar structure in determining deformation and fracture toughness in nanoscale structures. The lamellar boundaries are highly effective in inhib ...
A simple model based on dislocation theory allows the construction of a fully defined system of differential equations and the calculation of curves that correspond to different mechanical tests such as stress relaxation, the creep test and the imposed stra ...
In this thesis I report on the unique novel possibilities offered by combining pulsed laser deposition (PLD) film growth of high temperature superconductors with angle integrated and angle resolved photoemission spectroscopy (PES and ARPES). The originalit ...
We used pulsed laser deposition, with a Bi2Sr2CaCu2O8+x target, to grow films ranging from (1/4) to 10 unit cells thick. We studied these films, and reference Bi2Sr2CaCu2O8+x single crystal samples, using angle-integrated photoemission, core level photoemi ...
Cascade damage simulations in a 12 nm nanocrystalline Ni sample are presented. Sinks present in the sample such as grain boundaries and vacancy defects influence the movement of self-interstitial atoms (SIAs). Two temporal mechanisms of SIA activity during ...
Lithium abundances and isotopic compositions were measured by ion microprobe in individual grains of pyroxene, and in a few maskelynites and Ca-phosphates grains, from the Martian meteorite Northwest Africa 480 (NWA 480). ...
Understanding of polarization reversal mechanisms in ferroelectric films is essential for evaluation and prediction of the properties of ferroelectric devices including nonvolatile memories. The widely accepted approach based on the domain wall motion kine ...
