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...

Due to its deltaic geographical position and precarious socioeconomic and demographic conditions, Bangladesh is recognized worldwide for its exposure to recurring environmental hazards. Based on a 21-month long field study in two fishing villages that are characterized by distinct ecological settings and ethnic groups, this article examines the arrays of cross-scale environmental, social and in...

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 ...

This work presents ped – the physics engine editor. It builds on the existing pe framework to compute rigid body simulations, and introduces an interactive tool to set up, manipulate and examine pe world simulations, via a flexible and easy to use GUI. While in the original pe it is only possible to construct arbitrary simulations in the form of hardcoded programs, ped offers an interactive and...

a novel modified ni-zsm-5 nanozeolite was fabricated via an organic template-free hydrothermal route. the average particle size of ni-zsm-5 nanozeolite was calculated to be 85 nm by scanning electronic microscopy. then, carbon paste electrode (cpe) was modified by ni-zsm-5 nanozeolite and ni2+ ions were then incorporated to the nanozeolite matrix. electrochemical behavior of this electrode was ...
