Wet hydrogen peroxide catalytic oxidation of malachite green over Fe2O3/Kaolin catalyst: optimization of reaction parameters
  • Abstract
  • Keywords
  • Reference
  • Full Article
This study presents an experimental investigation of wet hydrogen peroxide oxidation efficiency for the treatment of dye wastewater. In this purpose, Fe2O3/Kaolin catalyst was prepared by wet impregnation method and used for accelerating the degradation of malachite green under a wide range of critical metrics including processing temperature, catalyst dosage and hydrogen peroxide volume. The results indicate that satisfactory conversions of malachite green were atteint at high temperature levels and catalyst dosage. While the change in hydrogen peroxide volume has a dual effect on malachite green conversion, higher or lower values than 7ml can cause a negative impact on reaction performances. Therefore, the synergism of these optimized parameters has contributed to promising results, as suggested by a valuable improvement in catalyst activity which can promote 94.78% of malachite green removal rate.

Effect of Elevated Temperature on Compressive Strength of Fly Ash Blended Cement Concrete
  • Abstract
  • Keywords
  • Reference
  • Full Article
This study evaluates the effect of elevated temperatures on the compressive strength of fly ash blended cement concrete. The materials used for this research were ordinary Portland cement, clean river sand as fine aggregates, crushed granite chippings as coarse aggregates, potable water, fly ash and Rheobuild (a water reducing admixture). The characteristic strength of 25 N/mm2 corresponding to the mix design and a target mean crushing value of 38.12 N/mm2 were used. Fly ash was added in percentages of 0%, 5%, 10%, 15%, 20%, and 25% of ordinary Portland cement. 1.2% of Master Rheobuild ® 561M was combined to all fly ash blended mixes. Batching was done by weight.........

Sensors for airbag systems
  • Abstract
  • Keywords
  • Reference
  • Full Article
This paper discusses a known concept, which has proven itself to be of crucial importance, as it continues to saves lives on a daily basis. This concept, is known as an airbag system. An Airbag is an automated vehicle safety restraint system for the passengers, which inflates itself upon impact, to protect the passengers. This topic involves continuous research and developments on its design, material, and performance in making this life saving safety device further efficient. However, success of any safety restraint device depends on its correct implementation and certain safety rules to be followed. Keywords; Airbags; sensors; vehicles ;restraint systems
