Latest Invention: Tea Bag that Uses Nanotechnology to Clean Drinking Water One of the latest inventions developed by researchers from Stellenbosch University in South Africa is a one of a kind "tea bag" that makes use of nanotechnology to clean drinking water‚ making it free from contaminants and bacteria. It would be interesting to note that the "tea bag" is made of the same material that is used to make the actual tea bags. The only difference is that in the Stellenbosch researchers’ invention

Synthesis of Phenols You can prepare phenols in large quantities by the pyrolysis of the sodium salt of benzene sulfonic acid‚ by the Dow process‚ and by the air oxidation of cumene. Each of these processes is described below. You can also prepare small amounts of phenol by the peroxide oxidation of phenylboronic acid and the hydrolysis of diazonium salts. Pyrolysis of sodium benzene sulfonate In this process‚ benzene sulfonic acid is reacted with aqueous sodium hydroxide. The resulting salt

Abstract. An innovative and novel technology method of processing called Turbo-Mixing Reactive Precipitation (TMRP) design proposed as an alternative to this current processing or conventional productions of finer precipitation calcium carbonate (nano-PCC) in turbo-mixing conditions. In this paper‚ the effect of the stirring rate onto morphology‚ particle sizes and reaction time of the precipitated CaCO3 particles was discussed. CaCO3 nano particles with an average particle size of approximately
