1. Dye-sensitized nanostructured metal oxide electrodes : Photoelectrochemical, quantum chemical and electron spectroscopic studies
Abstract : Solar cells based on dye-Sensitized nanostructured electrodes are promising for solar energy conversion. High overall light-to-energy conversion efficiencies have been obtained for systems based on TiO2 (7%) and ZnO (2%). The photocurrent losses in these electrodes have been investigated by photoelectrochemical methods. READ MORE

2. Treatment of Textile Wastewater by Combining Biological Processes and Advanced Oxidation
Abstract : Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. Dyes, detergents, surfactants, biocides and more are used to improve the textile process and to make the clothes resistant to physical, chemical and biological agents. READ MORE

3. Ink-paper interaction : a study in ink-jet color reproduction
Abstract : An ink jet printing system consists of three fundamental parts: inks, printing engine, and substrates. Inks are materials creating color by selectively absorbing and scattering the visible illumination light. The printer acts as an ink distributor that governs the ink application. READ MORE

4. Unsaturated Solute Transport in a Semiarid Catchment - Nonlinear Analyses and Modelling
Abstract : Unsaturated solute transport is highly variable and therefore difficult to predict. In semi-arid areas, where water resources are limited, the presence of macropores is of great importance for crop production. The bromide ion (Br-) and dye tracers are useful for studies of water movement. READ MORE

5. Evaluation of Modern Irrigation Techniques with Brackish Water
Abstract : Modern irrigation techniques are becoming increasingly important in water-scarce countries especially in arid and semiarid regions. Higher crop production and better water use efficiency are usually achieved by drip irrigation as compared to other irrigation methods. READ MORE
