Application of TiO2–WO3 Composite for Continuous Reduction of Chromium(VI) in Light-limited Condition
Authors: Rand Elshorafa, Dong Suk Han, Hyunwoong Park and Ahmed Abdel-WahabHexavalent chromium (Cr(VI)) is toxic and hazard chemical to human health and it is categorized as a carcinogen chemical. Cr(VI) is released from many industrial processes such as electroplating, metal finishing, and textile/leather dyeing. Although there are many treatment technologies for removal of Cr(VI), the photocatalytic treatment using metal oxide semiconductor (SC) materials has been shown to be a promising tech Read More

Role of Biodiesel in the Enhancement of GTL Diesel Fuel Properties
Authors: Nimir Elbashir, Wajdi Jamal Ahmed, Ahmad Alrachid, Nasr Mohammed and Marwan ElwahshThe Conversion of natural gas into synthetic liquid fuel carried out through a catalytic conversion process, known as the gas-to-liquid (GTL) technology, had a great impact since its discovery. The process utilizes the Fischer-Tropsch synthesis (FTS) chemistry that was first developed in 1925. Gas-to-liquid (GTL) fuels are synthetic fuels that are intrinsically cleaner than conventional fuels.[1] They are environmentally beni Read More

The Elimination of Selenium from Contaminated Water using Sulfide or Dithionite Activated by UV Light
Authors: Bahngmi Angela Jung, Aya Safan and Ahmed Abdel-WahabSelenium (Se) is an essential trace element for animals and humans because it functions as an antioxidant and catalyst for the production of active thyroid hormone. However, higher intake of Se can cause disease and death to humans. This study investigates the removal of inorganic Se (selenite, Se (IV)) from contaminated water which is known as less bioavailable and more toxic than organic forms. Several technologies Read More

Experimental and Numerical Analysis of Heat Transfer in Grooved Tubes for Solar Collector Applications
Authors: Ben Alex Baby and Y. Raja SekharSolar thermal energy research and utilization is progressing rapidly since it is clean energy and can achieve carbon credits in developed and developing countries. The energy conversion efficiency of most of the solar collectors is low, as much of the energy absorbed by collectors is lost due to transient atmospheric conditions. Reduction of losses and improving the performance of collectors by providing economical soluti Read More
