We report a facile process to fabricate cuprous thin films by thermal oxidation of copper substrates. Structure and phase identification were studied by X-ray diffraction measurement and Raman spectroscopy. Scanning electron microscopy was utilized to study surface morphology of the as-fabricated thin films and optical properties of the samples were investigated by diffused reflectance spectroscopy.

Gulabjamun is traditional dairy product of the Indian subcontinent. The physico-thermal properties of Gulabjamun during sub-baric frying were analyzed at varying temperatures. The Gulabjamun balls were fried at three temperatures 110,115 and 120°C for 300s.The average sphericity values of Gulabjamun were derived from the dimensions measured along the three major axes as 0.969 0.002 to 0.989 0.002. The expansion ratio values varied from 1.338 0.10 to1.410 0.06 after 300s of frying. The Apparent density values decreased with increase in the frying temperatures.

In this study, high temperature oxidation-resistant NiCr/Al duplex coatings on carbon steel substrate have been fabricated by electrical wire arc-spraying process. The oxidation resistance properties of NiCr/Al duplex coating system have been evaluated at 800 °C during retention times of 1.5, 3.0, 4.5 and 6.0 hours. The morphology and chemical composition of their cross-sectional structures were investigated using scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS).
