Recent Developments in Solar Photovoltaics and Thermal Hybrid Technology
Abstract: The electrical performance of solar PV panel decreases with increase in the panel/module temperature which is cause of concern in the summer season. To decrease the effect on electrical performance due to increase in module temperature, heat is extracted from the module and used as thermal energy. Heat exchanger or heat extraction device is put on the rear surface of the PV panel and working fluid or coolant is flowed …

Effects of Oil Extraction Methods on Bio-diesel Production from Wild Grape Seeds: A Case Study of Soxhlet Extraction and Mechanical Press Engine Driven Expeller Methods
Abstract: In this research, two samples of wild grape seeds (Lannea Microcarpa) were used to produce biodiesel. The first sample was washed; dried and powdered, oil was extracted from the sample using soxhlet extraction method with n-hexane as solvent. The second sample was washed and dried, oil was extracted from the sample using mechanical press engine driven expeller. The oil yield from the first method was 33.3% while the oil yield …

Performance Evaluation of Petrol-Ethanol Blends and Testing on Multicylinder 4-Stroke SI Engine
Abstract: The usage of different alcohols as a fuel for spark ignition (SI) engines has been in progress since the invention of engine, with ethanol being renewable, bio-based and ecofriendly is the best replacement for petrol as fuel in SI engines. Ethanol is derived basically from sugarcane, cassava, corn and other waste biomass materials. The choice of ethanol as a fuel is due to the positive influence on engine performance due …

Parametric Study of Parabolic Trough Solar Collector System: A Review
Abstract: The detailed thermal analysis of a parabolic trough collector (PTC) was carried out to predict the thermal performance. The analysis is based on the established theory of PTC—the radiation absorption, heat loss from the collector, and temperature distribution on the plate. An analytical program, suitable for use on a digital computer is developed for the purpose of studying the hourly behavior of a solar collector. The exergy output is optimized …

Kinetic Studies of Pristine and Nanonickel Catalyzed Ammonia Borane
Abstract: The high hydrogen content chemical hydride, Ammonia Borane (NH3BH3, AB) is considered in its pure and catalyzed form for decomposition kinetics. The thermodynamics and slow kinetics are the major issues in addition to potential damage the material likely to cause to the fuel cell. The ability of AB for faster dehydrogenation at lower temperatures with Nickel in its nanoform is explored. The release kinetics, activation energy is computed using Kissinger …
