Vitamin C is well known for its role in fighting off the common cold, infections, heart diseases and cancer where it serves as an antioxidant. It acts as reducing agent that is able to keep iron ions in the more readily absorbed ferrous (Fe(II)) form, which facilitates the absorption of nonhemic iron from the gastrointestinal tract. This book provides maximum information about the kinetics and thermodynamics in a systematic manner regarding influences of different factors such as temperature and pH on the rate of oxidation of vitamin C by ferric chloride hexahydrate in the absence and the...

Tin oxide nanoparticles were prepared by hydrothermal method using octadecylamine surfactant as a templating agent. The synthesis was carried out at different concentration of surfactant keeping all other reaction conditions constant i.e time, intensity and temperature. The particle size decreases with the increase in concentration of surfactant up to critical micelle concentration (CMC). After CMC, increase in particle size occured with the increase in concentration of surfactant and this was attributed to the formation of micelles. The nanoparticles were applied as nanocatalyst under UV and...

Hydrothermal method was used for the preparation of tin oxide nanoparticles in the presence of isoamyl alcohol as solvent for surface directing agent. The effect of varying concentration of precursor and solvent was studied while other parameter like time and temperature were kept constant throughout the experiments. The nanoparticles were characterized by X-ray Diffraction, Fourier Transform Infrared Spectroscopy, Scanning Electron Microscope and Thermal Gravimetric analysis. Functional groups was confirmed by FTIR. Particle size was calculated by XRD analysis as well as TEM images while TGA...
