“Silicon nanocrystals (Si-ncs) have been produced by implantation of Si(+) in excess into SiO(2) followed

by both annealing and passivation using argon or nitrogen. Nitrogen increases the photoluminescence (PL) emission and shifts the spectra toward the blue. The measured Si-nc diameter is 4.3 and 3.8 LY3039478 nm after annealing performed under Ar and N(2), respectively. A significant quantity of nitrogen atoms has been detected in all samples by resonant nuclear reaction analysis (RNRA). The nitrogen concentration is significantly higher when the annealing and passivation are performed

in a nitrogen environment, in agreement with a larger Si-N vibration signal on the Raman spectra. The depth profiles of nitrogen are very similar to those of Si-nc, suggesting that the N(2) molecules may diffuse in the SiO(2) during the annealing and then are trapped in proximity to the Si-nc. In addition to Si(+), AZD7762 in vitro the implantation of N(2+) to concentrations of 3 and 6 at.% produced a decrease in the PL intensity (accentuated at the higher concentration) and an increase in the Raman signal associated to Si-N vibrations. These results suggest that a relatively low nitrogen atomic fraction enhances the PL emission, since a large nitrogen concentration impedes the formation of Si-nc thus significantly decreasing the PL intensity.

“Asperger syndrome

hinders adaptation to developmental challenges during childhood and adolescence, particularly with regard to interpersonal relationships. Individuals with Asperger syndrome display lack of empathy and limited ability to understand social and emotional exchanges with other people. Individuals with Asperger syndrome are significantly exposed to the risk of suicidal behavior, especially during adolescence. The authors describe cases of suicidal behavior in two adolescent boys with Asperger syndrome.”
“An investigation of the effect of interparticle interaction and particle size distribution has been carried out on iron oxide nanoparticles SB203580 mouse dispersed into porous Vycor glass. gamma-Fe2O3 nanoparticles dispersed into monoliths of Vycor glass were obtained using impregnation-decomposition cycles through the single-source metallo-organic decomposition process. Magnetic properties were investigated by ac magnetic susceptibility measurements, as a function of temperature at different frequencies, by measuring zero-field-cooled and field-cooled magnetization curves and by constructing hysteresis loops at different temperatures. A log-normal size distribution of monodomain nanoparticles has been deduced from the analysis of the magnetization curves.
