today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

We report panchromatic light harvesting in hybrid TiO(2)/P3HT photovoltaic devices using a porphyrin dye that complements the light absorption of P3HT. The high short circuit photocurrent (12.1 mA cm(-2)) obtained is found to be due, in part, to Förster resonance energy transfer from the P3HT to the dye.

Abstract Mechanical properties, elastic moduli, transmission factors (TFs), and gamma-ray shielding performance of quaternary glass systems with chemical composition (0.25? x )Bi 2 O 3 – B ?0.75(50%P 5 ?50%V ), where = 0.05 (S1), 0.10 (S2), 0.15 (S3), 0.20 (S4) mol%, were comprehensively studied. The MCNPX code, Phy-X/PSD software, the Makishima–Mackenzie model utilized to achieve mentioned pur...

An integral part of this project was to conduct an investigation of the full scale septic system that has been operating continuously at Modern Landfill since 2000. The design of this system was described in detail in Spagnoli et al., (2001) This system provides an ideal test bed to evaluate the long-term acceptability of tire derived aggregate (TDA) as an alternative to stone as the system’s a...

Abstract We report the mechanical properties, elastic moduli, and gamma ray attenuation properties of some TeO 2 –WO 3 –GdF glasses. Using chemical composition selected glasses, dissociation energy per unit volume ( G t ) packing density V were calculated. values, Young’s, Shear, Bulk, Longitudinal Modulus, Poisson’s ratio glasses are Next several fundamental such as linear mass coefficients, h...

Regularly spaced TiO2 nanotubes were prepared by anodizing a titanium substrate in triethylene glycol electrolyte at elevated temperature. In comparison to conventional TiO2 nanotubes, spaced nanotubes possess an adjustable spacing between the individual nanotubes; this allows for controlled buildup of a hierarchical nanoparticle-on-nanotube structure. Here, we use this principle for layer-by-l...

We investigate the time-dependent nonlinear optical absorption of a clay dispersion (Laponite) in an organic dye (rhodamine B) water solution displaying liquid-arrested state transition. Specifically, we determine the characteristic time tauD of the nonlinear susceptibility buildup due to the Soret effect. By comparing tauD with the relaxation time provided by standard dynamic light scattering ...

In this study, an Escherichia coli (E. coli) based transcription translation cell-free system (TX-TL) was employed to sample various enzyme expression levels of the violacein pathway. The pathway was successfully reconstructed in TX-TL. Its variation produced different metabolites as evident from the extracts’ assorted colors. Analysis of the violacein product via UV-Vis absorption and liquid c...

The effect of molecular dissociation on the exchange-correlation Kohn-Sham potential vxc has been studied by the construction of vxc from the ab initio correlated density r for the monohydrides XH ~X5Li, B! at several bond distances R~X—H!. The molecular dissociation manifests itself in the formation of a characteristic peak of vxc in the bonding region. The partially integrated conditional pro...
