Polymeric Biomaterials (Mingyu Li z3369978) The use of polymers in biomedical applications is now widely accepted and they are termed with the generic name of polymeric biomaterials. A biomaterial can be defined by their function as a material in contact with living tissue that used to the treatment of disease or injury‚ and to improve human health by restoring the function of tissue and organs in the body.x Polymeric biomaterials in medicine include surgical sutures‚ drug delivery vectors‚ orthopedic

Abstract: Saponification is an esterification process that is used to make so from the hydrolysis of fats and oils. This process have the glycerol molecule‚ and a sodium carboxylate salt in most case sodium stearate being formed‚ however this salt depends on the base being used. In the experiment 23ml of vegetable oil was mixed with 20ml of ethyl alcohol along with 20 ml of 25% sodium hydroxide in a 250-mL Erlenmeyer flask. The content was then heated on a water bath whilst gently mixing with

Free Radical Bulk Polymerization of Styrene This protocol describes the bulk polymerization of styrene at 60 oC using 2‚2´azobisisobutyronitril (AIBN) as an initiator. The monomer styrene first has to be purified before it can be used. The purification is performed in order to remove inhibitors and impurities‚ which can

• The equilibrium law DYNAMIC EQUILIBRIUM forward A +8 reaction ""r=====~’~ reverse reaction Most chemical reactions do not go to completion. Once some products are formed the reverse reaction can take place to reform the reactants. In a closed system the concentrations of all the reactants and products will eventually become constant. Such a system is said to be in a state of dynamic equilibrium. The forward and reverse reactions continue to occur‚ but at equilibrium

stirred and heated to about 82 degrees. Next‚ it is pressed into a compartment and rotated at a high speed and the paste and water/oil are separated. Now the oil may be bleached‚ deodorized and refined. Olive oil is composed mainly of mixed triglyceride esters of oleic acid‚ palmitic acid‚ and other fatty acids. It also has squalene‚ and sterols. The least processed forms of olive oil have more monounsaturated fatty acids than other olive oils. Olive oil has good amounts of vitamins E and K‚ and very high
