Unit 4 Material Chemistry

翻译

1、Ceramics are compounds between metallic and nonmetallic elements, Common ceramic materials include aluminum oxide, silicon dioxide, silicon carbide and silicon nitride.

2、A metal is a solid material that is typically hard, opaque, shiny, and features good electrical and thermal conductivity. Metals can be pressed permanently out of shape without breaking or cracking.

3、Metals and metal alloys may be strengthened by the uniform dispersion of several volume percent of fine particles of a very hard and inert material. The strengthening mechanism involves interactions between the particles and dislocations within the matrix.

4、A number of metals and alloys passivate, or lose their chemical reactivity, under some environmental circumstances. Stainless steels and aluminum alloys exhibit this type of behavior.

5、Graphene is an form of carbon consisting of a single layer of carbon atoms arranged in a hexagonal lattice. It is a semimetal with small overlap between the valence and the conduction bands.

6、A semiconductor material has an electrical conductivity value falling between that of a metal, like copper, gold, etc. and an insulator, such as glass. Their resistance decreases as their temperature increases, which behavior is opposite to that of a metal.

7、Ceramic materials have many important advantages, such as high mechanical strength and high temperature resistance, but their brittleness limits their applications in many aspects.

8、Solid solution strengthening is a type of alloying that can be used to improve the strength of a pure metal. The technique works by adding atoms of one element to the crystalline lattice of another element. The alloying element diffuses into the matrix, forming a solid solution.

9、In fiber glass, small glass fibers are embedded within a polymeric material. Fiberglass is relatively stiff, strong, and flexible. In addition, it has a low density.

10、The result of a DSC experiment is a curve of heat flux versus temperature or versus time. There are two different conventions: exothermic reactions in the sample shown with a positive or negative peak, depending on the kind of technology used in the experiment.

Unit 5 Introduction of Polymer Chemistry

翻译以下句子

1、The development of controlled living radical polymerization methods has been a long-standing goal in polymer chemistry, as a radical process is more tolerant of functional group and impurities and is the leading industrial method to produce polymers.

2、The most basic requirement for polymerization is that each molecule of monomer must be capable of being linked to two or more other molecules of monomer by chemical reactions. There are a multitude of chemical reactions and associated monomer types that can be used to effect polymerization.

3、Cationic polymerizations are chain reactions that can be considered in terms of initiation, propagation, chain transfer and termination processes. The exact mechanism often depends on the type of initiator, the structure of monomer and the nature of the solvent.

4、Ring opening polymerization is a form of chain-growth polymerization, in which the terminal end of a polymer chain acts as a reactive center where further cyclic monomers can react by opening its ring system and form a longer polymer chain.

5、Bulk polymerization is the simplest process and involves only the monomer and a monomer-soluble initiator. The high concentration of monomer gives rise to high rates of polymerization and high degrees of polymerization.
