On the prospects of biochemistry and polymer materials

The chemical industry belongs to a traditional industry, and the development speed can not be compared with electronics, communications, computers, etc., and the visible salary of course has no way to compare with these industries, but a student who is not one of these majors to engage in those jobs, and the possibility of success in competing with people born in the class should not be as big as you in this industry.

There is a lot of work that can be done in polymer materials and engineering, and it is recommended that you learn English well, as this tool is more important than computer knowledge in your daily work. Polymer material products have developed particularly rapidly in China in recent years, such as: PP, PE, PS, PET, PU, PC, PVC, ABS and other plastics, as well as various resins

Alkyd, unsaturated, polyamide, phenolic, and various PU polyurethanes are all part of your employment. It will be easy to find a job, and you must try your best to learn English well in professional courses. It's good to get a job in technology or marketing after you come out.

Many of my friends who majored in chemical engineering are now working in your field.

Many of my friends who are still in college (including me before) feel that they don't know what to learn in school, because many of the things they learn will definitely be useless in the future, so from my experience (maybe I made the mistake of empiricism!! Professional courses, English is what you can spend time learning now, one is your professional advantage, it is likely that you will use it to eat for a lifetime, the other is a communication tool, now it is a global village, and you will know that most of the jobs with good pay are foreign bosses, and it is a very sad thing to not speak English well! Although bioengineering includes genetic engineering technology, enzyme engineering technology, cell engineering technology and fermentation engineering technology.

However, now domestic bioengineering is generally in the direction of food science and engineering. In other words, the main research direction is in fermentation engineering.

The main direction of employment is scientific research related to fermented products, such as yogurt, soy sauce, vinegar, wine, etc. At present, the employment is okay, but most of them are enterprises, and if you want to enter a public institution, you have to think about it.

Bioengineering is an engineering discipline, which has a lot of requirements for mathematics, physics and chemistry, and the main study of biology is microorganisms. Biotechnology and biotechnology, on the other hand, are mostly science or agriculture. If you simply like biology, you might as well consider these two majors.

Relatively speaking, the employment will be wide but not precise, depending on the direction of the school you apply for, for example, agricultural colleges may be biased towards biological jobs such as animal husbandry.

Summary. Polymer materials are indispensable for any industry, from dressing and eating, computers and mobile phones, to building buildings and aerospace. The demand for polymer materials and engineering professionals is still expanding, and it is not difficult to find a job that corresponds to the polymer materials and engineering major, but it is difficult to find a promising job.

Intuitive data show that the employment rate of polymer materials is relatively high, at more than 92%. Graduates choose state-owned enterprises, private and private enterprises, foreign-funded enterprises, and scientific research and design units.

The experience of the brothers and sisters is that there are jobs to be found in the main directions of polymer materials, such as plastics, rubber, synthetic fibers, adhesives and coatings, and composite materials in the interdisciplinary fields.

Biopolymer materials are also known as hydrogen storage materials. Some transition metals, alloys, or metal interferides can absorb or release hydrogen in large quantities under certain temperature and pressure conditions, and can be used as biopolymer materials. [1

Hydrogen storage materials can be used as a transport medium for hydrogen, as well as a range of other uses, such as energy conversion media, hydrogen separation, refining and separating hydrogen isotopes, catalysts and sensitive elements. Here are a few typical application examples.

Hydrogen refrigeration and heating equipment.

Using the characteristics of hydrogen storage materials to release (absorb) heat when absorbing (discharging) hydrogen, it can make cold and warm equipment for energy storage - chemical heat source pump, which has small heat loss and can be changed from first-class waste heat to high-quality heat. A chemical heat pump consists of a gas tank made of two different hydrogen storage materials, connected by a valve with a switch. When the valve is opened, the high-pressure tank A that forms hydrides at low temperature will release hydrogen, and a large amount of heat will be released for the absorption of low-pressure tank B that forms hydrides at high temperatures, which can be used for heating.

Tank B can be heated with cheap thermal energy, so that the released hydrogen can be absorbed and stored by tank A. The thermal energy used to heat tank B can be cheap electricity from the trough of electricity consumption at night, or waste heat for industrial use, waste heat and solar energy. Therefore, hydrogen storage alloys can be made into devices that utilize waste heat, waste heat and cheap energy and energy saving.

If cooling is to be done, hydrogen storage materials can be used to absorb heat and achieve the purpose of cooling.

Separation and refining of hydrogen.

Hydrogen storage alloys such as Lani5 have great selective absorption of hydrogen, so hydrogen separation and refining can be carried out. For example, refined high-purity hydrogen can be obtained by reacting a mixture of Ar, N2, CO2, Co, CH4 and H2 with a multi-element alloy of Lani5 and MnNi5 under pressure, and the hydrogen is selectively absorbed, then heated and desorbed. The purity of 1000L of refined hydrogen using the above materials is in, and the output is 500ml min.

In addition, the hydrogen storage material can also be used to drive the machine with energy conversion; It is used in hydrogen-air fuel cells; It can also be used as a catalyst for the synthesis of hydrogen and the separation of incoming hydrogen, etc. In short, the application field of hydrogen storage materials is very broad and has a tendency to expand.
