Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

The 21st Century Energy Solution: Liquid Flouride Thorium Reactor Recently the spotlight has been set on renewable energies to assist with weaning off of greenhouse gas emissions‚ solving issues with energy independence‚ and to exploit their inherent renewability. Unfortunately our technology is not quite up to speed economically with our wish to rely completely on renewable energy‚ thus many non-renewable energies are recognized as viable options to power our economy (Fraser‚ 2011).

Liquid Chromatography – Laboratory #18 Introduction: We are using liquid chromatography to separate the colored substances in grape-flavored drinks. We separate the component dyes‚ and then we separate the flavorings and citric acids. Background: Chromatography is a process that is used to separate a substance into its component parts. The separation occurs between the stationary and moving phase of the lab. The moving phase consists of a fluid and the stationary phase consists of a solid
