When searching for new gravitational-wave or electromagnetic sources, the $n$ signal parameters (masses, sky location, frequencies,...) are unknown. In practice, one hunts signals at a discrete set of points in parameter space, with computational cost that is proportional to number these points. If fixed, question arises, where should be placed space? The current literature advocates selecting ...

dye sensitized solar cell was fabricated from a double layer photoanode. first, tio2 nanoparticles  were synthesized by hydrothermal method. these tio2 nps were deposited on fto glasses by electrophoretic deposition  method in applied voltage of 5 v and epd time of 2.5-10 min. then tio2 hollow spheres (hss) were synthesized by sacrificed template method with carbon spheres as template and ttip ...

In the current research project, sol-gel electrophoresis technique was utilized to grow titanium dioxide (TiO2) nanotubes. A titanium sol was prepared using organometallic precursors of titanium to fill the template channels. The prepared solwas driven into nanopores of porous anodic aluminum oxide templates under the influence of a DC electric field to form nanotubes on the pore walls. Tube fo...

Two approaches for metal ion incorporation were employed to introduce Ca2+ into SBA-15; Direct Synthesis (DS) and Wet Impregnation (WI). The non-ionic template was removed by two different methods; calcination and solvent extraction. The obtained catalysts were characterized by means of X-Ray Powder Diffraction (XRD), Energy Dispersive X-ray (EDX), and FT-IR spectroscopy. The bas...
