Materials Chemistry

Good afternoon ,boys and girls .It is my great honour to be here to talk something about my major—materials chemistry

First of all,What is materials materials chemistry? Materials are properly more deep-seated in our culture than most of us realize. Transportation,housing,clouthing,communication,recreation and food production—Virtually every segment of our everyday lives is influenced to one degree or another by materials. Historically, the development and advancement of societies have been intimately tied to the members’ abilities to produce and manipulate materials to fill their needs.

The development of many technologies that make our existence so comfortable has been intimately associated with the accessibility of suitable materials. Advancement in the understanding of a material type is often the forerunner to the stepwise progression of a technology.

The discipline of materials science or materials chemistry in the context of these two lectures involves investigating the relationship that exists between the structures and properties of materials.

Materials chemistry around us: Molecular electronic,medical materials, space exploration, new battlefield materials,etc.

Materials science is an interdisciplinary study that combines chemistry, physics, metallurgy, engineering and very recently life sciences. Show you some of our core curriculum: Inorganic and Analytical

Chemistry

? Organic Chemistry

? Physical Chemistry

? Mechanics of Materials

? Science and Protection Technology of Material Corrosions ? New Functional Materials……

As materials are everywhere around us,our career field is very wide. Our employment Direction Include chemical industry ,metal industry,pharmacy ,military affairs and

oceaneering. I believe that a and brighter future awaits us.

Thanks for listening!
