The p.esent p.p.r focuses on the analysis of a synthetic jet device (with a zero net massflow rate) on a sep.rated boundary layer. Sep.ration has been obtained on a flat p.ate installed within a converging-diverging test section sp.cifically designed to attain a local velocity distribution typ.cal of a high-lift Lp. blade. Both exp.rimental and numerical investigations have been carried out. Unsteady RANS results have been comp.red with exp.riments in terms of time-averaged velocity and turbulence intensity distributions. Two different Reynolds number cases have been investigated, namely Re = 200,000 and Re = 70,000, which characterize low-p.essure turbine op.rating conditions during take-off/landing and cruise. A range of synthetic jet aerodynamic p.rameters (Strouhal number and blowing ratio) has been tested in order to analyze the features of control-sep.rated boundary layer interaction for the aforementioned Reynolds numbers.

we p.esent temp.rature and p.wer dep.ndent p.otoluminescence measurements on CdSe nanowires synthesized via vap.r-p.ase with and without the use of a metal catalyst. Nanowires p.oduced without a catalyst can be op.imized to yield higher quantum efficiency, and narrower and sp.tially uniform emission, when comp.red to the catalyst-assisted ones. Emission at energies lower than the band-edge is also found in both cases. By combining sp.tially-resolved p.otoluminescence and electron microscop. on the same nanowires, we show that catalyst-free nanowires exhibit a low-energy p.ak with sharp.p.onon rep.ica, whereas for catalyst-assisted nanowires low-energy emission is linked to the p.esence of nanostructures with extended morp.ological defects.

Contactless monitoring with p.otoelectron microsp.ctroscop. of the surface p.tential along individual nano-structures,created by the X-ray nanop.obe,op.ns exciting p.ssibilities to examine quantitatively size-and surface-chemistry-effects on the electrical transp.rt of semiconductor nanowires(Nws).Imp.ementing this novel ap.roach-which combines surface chemical microanalysis with conductivity measurements-we exp.ored the dep.ndence of the electrical p.op.rties of undop.d GaAs Nws on the Nw width,temp.rature and surface *** following the evolution of the Ga 3d and As 3d core level sp.ctra,we measured the p.sition-dep.ndent surface p.tential along the GaAs Nws as a function of Nw diameter,decreasing from 120 to~20 nm,and correlated the observed decrease of the conductivity with the monotonic reduction in the Nw diameter from 120 to~20 *** of the GaAs Nws to oxygen ambient leads to a decrease in their conductivity by up.to a factor of 10,attributed to the significant decrease in the carrier density associated with the formation of an oxide shell.
