Texto completo da fonteWe have demonstrated an original way to induce a phase transformation in Si and Ge nanowires under external shear-stress. The transformation results in an unprecedented heterostructure with quasiperiodic embedded Ge-2H nanodomains distributed all along the nanowire. My thesisproject aims at understanding the mechanisms of this phase transformation and at characterizing the physical properties of the heterostructures 2H/3C in Si and Ge nanowires.We have carried out systematic structural analysis in Si- and Ge-2H/3C nanowires to evidence the key parameters of this phase transformation.The phase transformation occurs in shear bands localized along the (2-5-5) direction.The heterostructured nanowires are defined by a specific orientation relationship between the 3C and the 2H bands (both in Si and Ge nanowires)given by(1-10)3C//(-2110)2H and (110)3C//(0001)2H with the 2H bands lying mainly on (115)3C planes.The preliminary studies showed that shear-stress and the thermal budget above a threshold temperature of 350°C in Ge and 500°C in Si are mandatory for this transformation. These conditions meet the common criteria of a martensitic phase transformation. We have identified two key intrinsic parameters:the temperature and the nanowires crystallographic axis.In Si nanowires, we found that the formation of the shear bands i.e. the 2H nanodomains is related to the component of the shear-stress along the glide direction of the 3C/2H interface plane.Based on these results,the transformation could be consistent with a stress relief mechanism through the formation of (5-5-2)(1-15)3C shear bands.We have performed spatially resolved Raman measurements on single Si and Ge heterostructured nanowires to characterize their optical phonon modes.In Ge,we have detected 2 Raman bands at 288 cm⁻ ᴵ and 301 cm⁻ ᴵ attributed to the E2g and E1g + A1g + F2g modes.In Si, we have observed 3 Raman bands at 498, 515 and 520 cm⁻ ᴵ that are associated respectively to the E2g, A1g and F2g modes.Those values agree well with the literature.Moreover, we have performed Fourier Transform Infrared spectroscopy on transformed Ge nanowires to measure the optical band gap of the 2H phase.We have obtained a direct band gap of 0,58 eV attributed to the 2H phase and an indirect bandgap of 0,72 eV that might stem from the 3C phase. Those results are the first experimental data of the Ge-2H band gap.The values align well with the simulations that predict a narrow direct band gap for this structure.The 2H structure can also be achieved in bulk Si and Ge after unloading of the BC8 phase in a diamond anvil cell.The BC8 phase is unstable and convertsinto the 2H phase at room temperature in Ge or by thermal annealing in Si.In order to compare the bulk properties of the 2H phase, we have performedin-situ Raman and X-ray diffraction experiments in bulk samples by studyingvarious unloading pathways. In particular, unloading at room temperature ledto the formation of the ST12 phase or a mixture of the BC8 and ST12 phasesdepending on the unloading rate.The formation of the 2H phase is thuscomplex given its dependency on the unloading conditions and the hydrostaticconditions within the cell that are difficult to garanty. Our studies also reveala size effect. After unloading of Ge-3C nanowires, the nanostructures revertback to the 3C phase with an amorphous component detected.In addition, we have carried out in-situ band gap measurements in bulk Ge and Ge nanowires as a function of pressure.After unloading, we havemeasured optical gap values that are related to the band structure of theGe-ST12 allotrope with a direct bandgap of 0,53 eV and an indirect bandgapof 0,73 eV.Those results are consistent with the experimental values reported.The experiments on Ge nanowires showed an hysteresis behavior with theinitial value of the band gap measured after unloading.Those results clearly evidenced novel relaxation mechanisms at the nanoscale that need to be investigated

Texto completo da fonteRecently Franzetti et al. Discovered a new type of energy-independent self-compartmentalized proteases in Archaea. The particles were named TET for their tetrahedral three-dimensional structure. The TETs self assemble as large molecular weight complexes of about 500kDa. Their role in the organism is yet unknown. In P. Horikoshii, a hyperthermophilic Archaea from the deep sea, three TET proteases have been identified (PhTET1, 2 and 3). We have expressed and purified recombinant PhTET3. The enzyme was characterized biochemically and we determined the structure of a PhTET3 12 subunit complex by x-ray crystallography. In order to gain insight into its potential physiological role and to ascertain why there are three TET proteases in P. Horikoshii, the structure and the enzymatic properties of PhTET3 have been compared to the two other TET proteases that were characterized before. As self-compartmentalization plays an important role in functioning and regulation of proteases, the factors controlling PhTET3 oligomerization in vitro have been studied by analytical ultracentrifugation and small angle neutron scattering. Finally, under physiological deep sea conditions, the enzyme is exposed to high temperature (up to 100°C) and high pressure. In order to study the limits of stability of large molecular weight assemblies, the low-resolution structure and the enzymatic activity of PhTET3 have been monitored under high pressures and temperatures using small angle x-ray scattering and high-pressure spectrophotometry. Taken together, these studies revealed that the TET proteases of P. Horikoshii form an integrated peptide degradation systems and that PhTET3 exhibits unusual stability under high pressure and temperature as well as environment-associated enzymatic properties

Texto completo da fonteThis thesis presents our work on the rheology of two of the main minerals of the upper mantle: olivine and orthopyroxene. First, fined-grained polycrystalline aggregates (with grain sizes between 100 nm and 5 &m) of olivine and pyroxene were synthesized by Spark Plasma Sintering (SPS) and vacuumsintering. The samples were then deformed at pressures between 2 and 6 GPa in D-DIA presses installed on synchrotrons X-ray beamlines at NSLS and ESRF so thatmeasurements of the differential stress and strain could be obtained in situ. The influence of pressure on low-temperature plasticity of olivine was studied at room temperature (ID06 beamline, ESRF synchrotron, Grenoble). High-temperature deformation mechanisms of olivine and orthopyroxene were also studied between 900 and 1200°C (X17B2 beamline, NSLS synchrotron, New York). Mechanical results and microstructural analysis by EBSD suggest a deformation by diffusion creep. Rheological laws including the effect of pressure, temperature, differential stress and grain size were determined for each mineral. Under these conditions, orthopyroxene appears less viscous than olivine. Finally, two-phase aggregates (Ol/Px volume ration of 80/20 and 70/30) were also deformed. Differential stress, estimated in each phase, indicates the contribution of a second deformation mechanism, in agreement with microstructural observations
