Design and Development of Energy Efficient Eco Friendly Wooden Casing Led based Solar Lantern for Rural Area

Design and construction of fruit solar drier for rural settlements

This research focuses on the need for preserving fruits in rural areas to prevent waste. The solar drier is made of vital chambers i.e. the concentrator chamber (that harvests the solar irradiance), the transport pipe (that transports the heat generated by convection) and hanger chamber (where the fruits are placed). The temperature within the concentrator chamber and hanger chamber was monitor...

Development of Eco-Friendly Biodegradable Biolubricant Based on Jatropha Oil

Design the Voltage Acceptability Curves for Energy Efficient Led Lamps

This paper presents the design and develops of voltage acceptability curves for LED lamps. It is done with the mathematical representation of DC bus voltage of LED lamps internal ballast circuit during voltage sags. First, experimental analysis was done to determine the effect of voltage sag of LED lamp. From the findings on the variation of DC bus voltage during voltage sag, a mathematical equ...

Efficient and Eco-Friendly Procedure for the Synthesis of 2-Amino-4H-Chromenes Catalyzed by Diammonium Hydrogen Phosphate

An efficient and eco-friendly protocol for the preparation of 2-amino-4H-chromenes employing a multi-component, one-pot condensation reaction between aromatic aldehydes, malononitrile and1-naphthol has been developed. The reaction of 1-naphthol with malononitrile and various aromatic aldehydes was carried out i...

Efficient and Eco - friendly Synthesis of 1 , 7 - Naphthyridines

A microwave-promoted new easy, efficient, clean and environmentally benign method for the synthesis of 1,7naphthyridineand its derivatives from 2-cyano-3-pyridylacetonitrile has been developed. The desired products were isolated in excellent yields and high purity under eco-friendly conditions.The synthesized compounds were characterized by the IR, UV-Visible and H NMR spectral analyses along w...
