Abstract Solid oxide fuel cell (SOFC) works by converting chemical energy into electrical energy due to reforming, and it is one of the promising alternative source of energy for the future. In the present work, emphasis was given on increasing the electronic conductivity of anode material for SOFC. The Cu0.5Ce0.5O2-δ was prepared by mechanochemical (ball […]

Abstract This article presents photon to electricity conversion analysis, and absorption and impedance measurements, on a new class of solid solutions, known as SrTi1-xFexO3-y or strontium titanate ferrate (STF). Incident photon-to-current efficiency (IPCE), UV-vis absorption spectroscopy and electrochemical impedance spectroscopy (EIS) were performed. The STF samples were prepared by employing spray pyrolysis approach on ITO […]

Abstract Authors have presented an analytical approach on transient laminar gray gas flow past an oscillating vertical flat plate in the presence of natural convection and radiation. The fluid is considered to be a gray, absorbing-emitting radiation but non- scattering medium. The Rosseland flux approximation is employed to simulate radiation heat transfer contribution. We have […]

Abstract The International Research Establishment for Energy and Environment (IREEE) has started its passionate journey towards realizing energy-efficient and ecofriendly technologies for the future. Facilitating a platform for showcasing the research and development activities in these broad domains is vital in materializing this mission, and this was one of the motives behind IJATR as the […]

Abstract The building construction sector in the Kingdom of Saudi Arabia is the largest and fastest in the Middle East. It is estimated that 2.32 million new homes are to be built by 2020 in order to meet the demand of growing population. Despite possessing ample potential, the realization of solar energy technology in Saudi […]

Abstract Households are major energy consumers and have a significant contribute to the World’s final energy consumption and CO2 emissions. Among the energy end-use in buildings lies cooking. The energy saving potential of cooking appliances is large and an investment on the development of more efficient and less polluting stoves and ovens is necessary. Porous […]

Abstract Coupled heat and mass transfer in a saturated porous media supported by a vertical plate is analyzed. The fluid inside the porous medium is assumed to be governed by Darcy law. The combined effect of natural convection and radiation on heat and mass transfer inside the medium is investigated. Finite element method is applied […]

Abstract A novel class of materials namely SrTi1-xFexO3-y or strontium titanate ferrate (STF) with solid solution character, suitable for solar electricity conversion, has been developed. The STF films were prepared by spray pyrolysis technique, designated as 2STF, 3STF and 4STF in the order of increasing thickness. Scanning electron microscopy (SEM), X-ray diffraction (XRD), energy dispersive […]

Abstract Understanding the properties of airflow in the nasal cavity is very important in determining the nasal physiology and in diagnosis of various anomalies associated with the nose. This numerical study presents the characteristic flow features inside a female nasal cavity in comparison with the male models developed by other researchers. The study is based […]

Abstract Excellence in scientific research has become a necessity rather than merely a symbol of prestige. With the advent of digital media, the dissemination of research contributions has become very friendly. Every individual has inherent skills in research and its communication, which need to be identified and developed. Adequate motivation in this direction and the […]
