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

THERMAL INSULATION MATERIALS Thermal insulation materials are specifically designed to reduce the heat flow by limiting heat conduction‚ convection‚ radiation or all three while performing one or more of the following functions: The main function of insulation is to reduce the heat transfer‚ the insulation material must have the appropriate characteristic to slow down the transport of heat occurred by conduction‚ convection and radiation. Conduction loss in insulation is negligible. There are

The Identification and Production of Materials 1. Fossil fuels provide both energy and raw materials such as ethylene‚ for the production of other substances. Students Learn To: .2 Identify the industrial source of ethylene from the cracking of some of the fractions from the refining of petroleum. • Ethylene is produced either from natural gas or crude oil‚ which are mixtures of hydrocarbons. One method involves… Cracking: a process by which hydrocarbons with higher molecular

mechanical deformation process of different materials by three tests: tensile test‚ impact test‚ and fracture-toughness test. The materials evaluated in the tensile test were annealed 1045 steel‚ cold rolled 1045 steel‚ 2024-T4 aluminum and cast iron. 2024-T4 aluminum is concluded to be most ductile (25.7 % reduction in area) and cast iron the most brittle (123 MPa). Effects of cold rolling in 1045 steel are apparent‚ as it has the highest strength among the materials tested (402 MPa yield strength). Impact

Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:

VOL. 70‚ NO. 5‚ MAY 1982 Silicon as a Mechanical Material KURT E. PETERSEN‚ MEMBER‚ IEEE Abstract-Single-crystal silicon is being increasingly employed in a variety of new commercial products not because of its well-established electronic properties‚ but rather because of its excellent mechanical properties. In addition‚ recent trends in the engineering literature indicate a growing interest in the use of silicon as a mechanical material with the ultimate goal of developing a broad range

CONCLUSION 17 11 REFERENCES 18 ABSTRACT The diminishing wood resource and restrictions imposed on felling in natural forests‚ particularly in the tropics‚ have focused world attention on the need to identify a substitute building material that should be renewable‚ environment friendly and widely available. In view of its rapid growth‚ a ready adaptability to most climatic conditions and properties‚ superior to most juvenile fast growing wood‚ bamboo emerges as a very suitable alternative
