Hydrogenation technology is an important chemical upgrading process for low quality oil such as coal tar. Kinetic modeling for hydrogenation process remains a challenging task because of the large amount of compounds and complex reactions involved. Therefore, a new systematic methodology is...

Peat respiration that releases carbon dioxide (CO<Subscript>2</Subscript>) to the atmosphere contributes to regional and global change. Aeration associated with soil water content levels controls emission rates, but soil amendments might mitigate respiration. The objectives of this study were to examine the effects of...</subscript>

Landslides are the major natural hazards in many countries all over the world and are usually caused by heavy rainfall, water level change of reservoir, excavation, earthquake, etc. Whether the landslide occurs or not in rainfall season, the strength variation of slip-zone soils of landslide is...

Water starvation at the anode represents a challenging issue in the development of direct methanol fuel cells (DMFCs) operating with neat methanol. To tackle the issue, a multi-layered membrane, consisting of an ultra-thin reaction layer sandwiched between two thin membranes, is proposed and...

The thin layer solar drying of mango slices of 8mm thick was simulated and experimented using a solar dryer designed and constructed in laboratory. Under meteorological conditions of harvest period of mangoes, the results showed that 3 “typical days” of drying were necessary to reach the...

Models play an important role in fuel cell design and development. One of the critical problems to overcome in the proton exchange membrane (PEM) fuel cells is the water management. In this work a steady state, two-dimensional, isothermal model in a single PEM fuel cell using individual...

Transesterification of crude Jatropha oil in presence of tungstophosphoric acid (TPA) supported on activated carbon (AC) using ultrasound-assisted process was investigated. The generated catalysts were characterized for physical and chemical properties to examine the effects of different TPA...
