PREPARATION OF ALUMINA POWDERS 1. BAYERS PROCESS INTRODUCTION The Bayer Process was invented and patented in 1887 by Austrian scientist Karl Josef Bayer. Two to three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. DEFINITION The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). The aluminium oxide must be purified before it

EXERCISE 8-A: Preparation of Bacterial Smear and Simple Staining I. INTRODUCTION Bacterial smears are prepared for the purpose of viewing microorganisms under the microscope. Visualization of microorganisms in the living state is very difficult‚ not just because they are minute‚ but because they are transparent and almost colorless when suspended in an aqueous medium. A bacterial smear is a dried preparation of bacterial cells on a glass slide. Smears may be made from a dry culture (from a slant‚

Liquid Crystals from Coconut Oil Fatty Acids - Investigatory Project Liquid Crystals from Coconut Oil Fatty Acids Abstract Liquid crystals are fluids that are between the solid and conventional liquid phases. Liquid crystals are in widespread use‚ especially in optical technologies. They are synthesized by combining fatty acids with cholesterol. This study aims to utilize coconut oil as an alternative source of fatty acids for synthesizing liquid crystals since coconut is cheap and abundant

Emulsification of Oil Prepared for: Mrs. Elena Gallagher By: Anna Villanella March 25‚ 2014 Oil is a nonpolar molecule. Polar molecules have charged groups or atoms. Nonpolar molecules have no charged groups or atoms. Polar molecules‚ like water‚ are good solvents for other polar molecules. This means they molecules that react with the water disperse into the water. Nonpolar molecules don’t disperse in water because nonpolar molecules and polar molecules don’t interact. How exactly can we discover
