Q:Who can tell me which university chemistry is best for chemical materials?
Q:What is the difference between material chemistry and polymer chemistry in chemistry?
Material chemistry focuses on inorganic materials, and macromolecules are mainly studied for organic polymers
Q:What can I do after the chemistry of materials?
There are a lot of useful, this is a new discipline, the prospects for a good look. Is it not the aid of the chemistry of the Chinese?
Q:What is the employment situation of chemistry and materials?
In the materials science and engineering of the professional, the material chemistry graduates employment situation is quite good. Graduates suitable for materials related business, business, technical and administrative departments engaged in applied research, technology development, production technology and management work, suitable for scientific research institutions, colleges and universities engaged in scientific research and teaching work. Graduates mainly as R & D engineers, sales engineers, laboratory technicians, sales representatives, process engineers, quality inspectors, laborers, sales managers, junior high school chemistry teachers, technology research and development engineers, inspectors, high school chemistry teachers and other positions.
Q:What is the chemistry of girls?
Girls do not learn chemical and the like. Even if the issue does not consider the issue, but also consider the health problems. And even learn, and later not necessarily do this work, is a waste of time. University is not so easy to hang the Department. Good preparation before the test, not much of the problem. You can consider the professional category of human resources, partial management, later Ye Hao employment. If you think that repeat can not increase the number, or poor psychological quality, do not repeat it.
Q:What is the main work of the chemistry of materials after graduation?
Sales line growth route: salesman → sales director → regional manager → sales director
Q:Like we ordinary people how to buy some chemical materials, usually where?
Chemical reagents shopping malls are everywhere, we are Huadonghuahua glass, call to send, it can not find a lot of online. National control such as sulfuric acid, nitric acid and other public security bureau seems to require proof. It is not a scientific research institution school class is difficult to buy.
Q:What are the chemical materials?
Polymer is composed of carbon, hydrogen, oxygen, silicon, sulfur and other elements of the molecular weight of the organic compounds of high enough. Known as the polymer, because of its high molecular weight. Commonly used polymer molecular weight in a few hundred to several hundred The effect of high molecular weight on the nature of the compound is that it has a certain strength and can be used as a material, which is also a place where the polymer compound is different from the general compound, and because the polymer compound generally has a long chain structure, All the molecules are like a long line, many molecules together, it becomes a naked thread group, which is the polymer compounds with high strength, can be used as the structural material of the root causes.On the other hand, People can also be through a variety of means, with physical or chemical methods, or the interaction of macromolecules and other substances after the physical or chemical changes, so that the polymer compounds can become a special function of functional polymer materials.
Q:What are the basic knowledge of the basic course of material chemistry?
Materials Chemistry is a branch of materials science, including inorganic and organic chemical properties of various applications. Materials chemistry major courses mainly related to higher mathematics, mechanical drawing, computer applications, inorganic chemistry, organic chemistry, analytical chemistry, physical chemistry, physics, thermodynamics, materials chemistry, metallurgy, electrochemistry and other aspects of knowledge. As the professional in different schools in different directions, so the basic course will be slightly different.
Q:Does the material profession belong to chemical or chemical class?
There are two categories: one is subordinate to the mechanical materials, colleges and universities generally put this material professional in the mechanical college, the main research metal materials and mechanical hook; one is chemical and chemical, such as polymer materials Wait.
