Overview. This course is one of the . six on-line courses. developed under the BIOSCCEED project sponsored by the United States Department of Agriculture.. Objectives. To describe the principles and the instruments suited for testing and examining the molecular and macroscopic structural features of naturally occurring biomaterials with emphasis on the . Metal foams – most are made from . aluminium. , although steel can also be used. There are many benefits of metal foams, including a very good . strength-to-weight ratio. .. Metal foams are cellular structures made with metal rather than polymers. .

Metallic Bonds and Metallic Properties. How can you model the valence electrons of metal atoms?. Metals consist of closely packed cations and loosely held valence electrons rather than neutral atoms.. Metals. Look at the Periodic Table…. 75% of elements are metals!. Metals. They can vary a lot…. General Properties of Metals. Dense. Malleable. Ductile. Good conductors of heat and electricity. Shiny Lustre. ANTEENA. . LENS ANTENNA :-. . TRANSMITTING MODE. RECEVING MODE. FUNCTIONS. OF LENS ANTENNA. . It controls the illumination of aperture.. It collimates the electromagnetic rays.. Autumn 2015. (Source Biomaterials Science by Buddy Ratner, 3. rd. edition) . The most accepted definition of biomaterials is currently the one employed by the American National Institute of Health: . 4.4.1: Describe the metallic bond as the electrostatic attraction between a lattice of positive ions and delocalized ions. . 4.4.2. : Explain the electrical conductivity and malleability of metals. .

Metallic Bond – the force that holds metal atoms together. Metals do not form covalent bonds with one another because they do not have enough electrons in their outer shells to form stable octets.. By: . . . Dr. Murtaza Najabat Ali . (CEng MIMechE P.E.). 1. Definitions. . Biomaterial. . - . . “. is any synthetic material that is used to replace or restore function to a body tissue . Introduction. The . materials which are used for structural applications in the field of medicine are called . Biomaterials.. Such materials are used to replace the damaged or diseased body parts in human or animal bodies. This is possible because the mechanical, physical and chemical properties of biomaterials are comparable with that of host body..
