Heat powered water pump for reverse osmosis desalination

Glushenkov M., Bhosale R., Kumar A., AlMomani F., Kronberg A., Qatar University, QA

Reverse osmosis (RO) is one of the most widely employed technologies for water desalination. A drawback of this technology is high consumption of electricity by electric motors used for high-pressure water pumping. Energy consumption can [...]

The Effect of Intermediate Ozonation Process on Improving Biogas Production from Co-Digestion of Agricultural Waste and Manure

AlMomani F., Bhosale R., Kumar A., Qatar University, QA

Millions tons of solid waste (SW) are generated from agricultural, municipal, and industrial sources every year. The amounts of SW are expected to increase exponentially in the coming decades, due to the growth of the [...]

Potential for Green Algae Spirulina to Capture Carbon Dioxide from Gas Stream

Shurair M.S., AlMomani F., Judd S., R. Bhosale R., Kumar A., Qatar University, QA

Scientific evidences show that the earth’s climate is significantly affected because of the continuous emissions of greenhouse gases (GHGs). The increase in CO2 level in the atmosphere leads to global warming as CO2 is one [...]

Thermochemical Copper Oxide – Copper Sulfate Water Splitting Cycle for Solar Hydrogen Production

Bhosale R., Dardor D., Kumar A., AlMomani F., Ghosh U., Qatar University, QA

H2 is considered as one of the potential energy carriers due to its capacity of producing 143 MJ/kg of energy (higher in comparison with the oil, gas, and coal individually) and its environmentally friendly nature [...]

Sustained Solar Fuel Production in Multiple Thermochemical Cycles Using Sol-Gel Derived Ferrite Nanopowders

Bhosale R., Sutar P., Kumar A., AlMomani F., Alxneit I., Scheffe J., Qatar University, QA

According to the recent studies, it is expected that the global energy requirement will increase from 14 TW to 30 TW by the year 2050. Currently, fossil fuels are the major energy source utilized for [...]

In-situ DRIFTS Studies on CuNi Catalyst for Ethanol Hydrogen Production

Kumar A., Ashok A., Bhosale R., AlMomani F., Tarlochan F., Qatar University, QA

Ethanol dehydrogenation mechanism was investigated over catalysts containing Cu and Ni metals prepared by solution combustion synthesis. In situ DRIFTS studies were conducted on individual metals (Cu and Ni) as well as on CuNi alloy [...]
