Zn0.98-xMg0.02BxO nanoparticles with various dopant ratios (x = 0.00 - 0.05 increments of 0.01) were grown by using the sol-gel technique. The samples synthesized and X-ray diffraction, scanning electron microscopy, optical reflectivity, dispersive analyses used to obtain structural, electronic, properties, respectively. Williamson–Hall procedure was utilized structural properties. energy bandg...

Numerous neuroimaging studies have strongly implicated the amygdala in dreaming. Various neuropsychological dream theories propose roles for the amygdala in dreaming (particularly in the generation of dream affect), however little empirical research on its function in dreaming exists. Urbach Wiethe Disease is a very rare genetic condition which leads to calcification of the amygdala over time. ...

Review copy ± not for distribution (pss-logo will be inserted here by the publisher) pss-­‐Header will be provided by the publisher 1 Introduction The continuous random network (CRN) has become the accepted model for homogeneously disordered materials, and for good reason: such atomistic models reproduce the experimentally observed properties of the materials, including some of the finer detail...

Two different concentrations of CdCl(2) and (NH(2))(2)CS were used to prepare CdS thin films, to be deposited on glass substrate by chemical bath deposition (CBD) technique. CdCl(2) (0.000312 M and 0.000625 M) was employed as a source of Cd(2+) while (NH(2))(2)CS (0.00125 M and 0.000625 M) for S(2-) at a constant bath temperature of 70 °C. Adhesion of the deposited films was found to be very go...

The functional properties of polyvinyl pyrrolidone/polyvinyl alcohol (PVP/PVA) blend incorporated with non-stoichiometric tin sulphide (SnS) have been explored for optoelectronic devices. PVP/PVA Sn/S ratios (1:0.8–1:1.2) 1.0 wt.% SnS were prepared by casting method. effect the ratio on structure, optical and photoluminescent (PL) composite was examined Fourier transform infrared, UV-visible-NI...

Abstract A series of Dy 3+ and Eu co-doped zinc aluminoborosilicate (ZABS) glasses were synthesized by a high-temperature melt-quenching method. Visible NIR transitions - ions are observed through absorption spectra. reverse trend in the optical band gap values Urbach energy seen with addition ions. Photoluminescence studies recorded under different excitation wavelengths showed variation emiss...

Ternary alloyed Cd 0.7 Zn 0.3 Te colloidal quantum dots were synthesized under open atmosphere conditions. The characterized XRD studies, DLS technique and optical absorption measurements. Using tauc urbach relation the energy bandgap obtained. intensity depended nonlinear parameters of determined with Z-scan experimental setup using a green laser source working on continuous wave mode. coeffic...
