Transparent thin layers of cobalt-doped ZnO were produced with the pulsed laser deposition method. The cobalt content original solid solution was 20% at. crystallographic structure examined by X-ray diffraction, which showed that fabricated crystallized in wurtzite phase and had a dominant orientation along a-axis. texture coefficient (increasing from F = 0.08 for non-annealed layer to 0.94 ann...

In this work, a hydrothermal technique is employed to prepare titanium dioxide films on fluorine-doped tin oxide (FTO) substrates. A low-cost homemade autoclave was used fabricate iron-doped -TiO2 (1at. %Fe) at different reaction times from 1 4 hours. X-ray diffraction (XRD) patterns showed that the predominant phase rutile (R-TiO2) with peaks (101), (002), and (112). The XRD results increasing...

Nanocrystalline PbTe films are deposited on different substrates at room temperature through thermal evaporation. The films are stoichiometric single-phase polycrystalline with 200 texture. Electrical properties of the films are analyzed in the framework of a grain boundary channel conduction model. The index of refraction and extinction coefficient of PbTe films are extracted from infrared spe...

When presented in a neutral context, emotional items interfere with episodic encoding of temporally contiguous non-emotional items, resulting in dissociable valence-dependent retrograde and arousal-dependent anterograde modulatory effects. By studying two rare patients with congenital lipoid proteinosis (Urbach-Wiethe) and a focal disease emphasis on the basolateral amygdala (BLA), we demonstra...

A detailed study of the wavelength dependence of the formation of lenslets by photo-expansion in chalcogenide glasses is reported. Photo-expansion in chalcogenide glasses offers a one-step fabrication process to record surface structures such as gratings and microlenses. The process is purely optical and requires no fixing and etching to get the desired surface structure. Two competing effects,...

We welcome the comment by Urbach and Cotton (2008) on our exploratory analysis of the consequences of sexual selection for fisheries-induced evolution (Hutchings and Rowe 2008). Two primary conclusions emerged from our work. First, irrespective of the underlying cause, fisheriesinduced evolution of traits linked to reproductive success may lead to unanticipated consequences regarding the rate a...
