Abstract: The optical and photocatalytic properties of Nb2O5 sculptured thin films (STF) are investigated. Films are synthesized via sol- gel route using spin coating technique. The sol is prepared from niobium ethoxide. The films are prepared at different rpm to tailor the thickness. The structures of the films are investigated through XRD measurements. Refractive index‚ extinction coefficient and thickness of the films are determined from Variable Angle Spectroscopic Ellipsometery. The absorbance

The chemistry of hairspray What is hairspray: introduction Hair spray (or hair lacquer) is a common household aqueous solution that is used to keep hair stiff or in a certain style. Weaker than hair gel‚ hair wax‚ or glue‚ it is sprayed to hold styles for a short period of time. Using a pump or aerosol spray nozzle it sprays evenly over the hair. Hairspray was first developed and manufactured in 1948 by Chase Products Company‚ based in Broadview‚ Illinois.Its active ingredient is a suitable

compounds. One of the compounds formed during fermentation of molasses is ethanol. In addition to sugar‚ about 12 million litres of ethanol are produced annually at the two factories in Sevanagala and Pelwatta. Another by-product of the sugarcane industry is bagasse which could be used to generate electricity. In addition‚ animal feeds‚ bagasse based fiber boards‚ biogas‚ numerous organic compounds such as acetone‚ butanol etc. are other by-products of the sugarcane industry. Developing the Sugar
