Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

showed promising result in the drug delivery but their applicability is limited primarily to specific use because of short half-life in blood circulation. The circulation time of liposomes in the blood stream is dramatically increased by attaching polyethylene glycol (PEG) – units to the bilayer‚ known as long circulating (Stealth) liposomes. Main advantages of liposomes are that they offers suitable means for delivering drugs combined with the potential of improving the therapeutic index while greatly

essay will assess the impact of plastic bags on the environmental system and evaluate two effective and feasible solutions to solve this problem. Plastic bags lead to three main aspects of environmental influence. To begin with‚they are made of polyethylene‚which means they are non-biodegradable.(Casper‚2009)Plastic bags would need even 1000 years to decompose.(ibid.)Chemicals from them do not change during this time‚they just break down into many tiny bits.(kaplan‚2010)These plastic bags would release

EMULSION An emulsion is a mixture of two or more liquids that are normally immiscible ( non mixable). Emulsions are part of a more general class of two-phase systems of matter called colloids. Although the terms colloid and emulsion are sometimes used interchangeably‚ emulsion should be used when both the dispersed and the continuous phase are liquids. In an emulsion‚ one liquid (the dispersed phase) is dispersed in the other (the continuous phase). Examples of emulsions include milk‚ mayonnaise

Bead Beads A bead is a small‚ decorative object that is formed in a variety of shapes and sizes of a material such as glass‚ plastic‚ or wood‚ and that is pierced for threading or stringing. Beads range in size from under 1 millimetre (0.039 in) to over 1 centimetre (0.39 in) in diameter. A pair of beads made from Nassarius sea snail shells‚ approximately 100‚000 years old‚ are thought to be the earliest known examples of jewellery.[1][2] Beadworkis the art or craft of making things with beads
