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

Synthetic fibers are made from synthesized polymers or small molecules. The compounds that are used to make these fibers come from raw materials such as petroleum based chemicals or petrochemicals. These materials are polymerized into a long‚ linear chemical that bond two adjacent carbon atoms. Differing chemical compounds will be used to produce different types of fibers. Although there are several different synthetic fibers‚ they generally have the same common properties. Generally‚ they are known

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

Issue Investigation: Polyvinyl Chloride (PVC) Introduction: (Approximately 150 words) – KU3 · This investigation will be looking at the positives and negatives of using Polyvinyl Chloride (PVC)‚ and providing viewpoints on whether it is ethical to continue using this toxic plastic. PVC is a useful plastic‚ but can be harmful to humans and the environment. This plastic is used in medicinal tablet containers‚ to make bags for bedding‚ shrink wrap‚ deli and meat wrap‚ and tamper resistant lids

Identification and Production of Materials ================================ Ethene‚ Polymers and Ethanol ================================ Catalytic Cracking Oil refineries need to balance their outputs of various products (petrol‚ diesel‚ fuel oil‚ etc.) to match the demands of the marketplace. Catalytic cracking is the process in which high molecular weight (high boiling point) fractions from crude oil are broken into lower molecular weight (lower boiling point) substances in order to increase
