The famous European chemist Antoine LAVOISIER specializes in the famous saying of chemistry: “Without loss, there is no creation, everything can be transformed into each otherâ€, and it has become the motto of energy saving and emission reduction in all walks of life in the EU. From the perspective of industrial, transportation and domestic internal combustion engines, recycling and recycling large amounts of heat from internal combustion engines is the key to improving energy efficiency and reducing carbon dioxide emissions. The EU's Seventh Research and Development Framework Program (FP7) provides partial funding, led by Jaguar Land Rover Ltd of the United Kingdom, and the European POWERDRIVER R&D team involved in the multi-national industry and technology. The aim is to use the self-developed thermoelectric generator technology (TGEN) and advanced thermoelectric material technology to produce electricity in line with industrial or transportation applications at a low cost, thereby increasing the thermal power conversion efficiency of the internal combustion engine by 25%.
The R&D team first selected the Jaguar Car internal combustion engine as a new energy-saving prototype design model. Using advanced thermoelectric conversion material technology, under the premise of optimizing cost performance and ensuring thermal stability, the prototype designed and developed can output an additional 300 watts of electricity, equivalent to 2.5% of the overall energy saving of the internal combustion engine. Using two heat exchangers, a high temperature section heat exchanger and a low temperature section heat exchanger, the waste heat generated by the exhaust pipe of the internal combustion engine generates a temperature difference between the two heat exchangers (the greater the temperature difference, the better) Thermoelectric generator technology (TGEN) produces electricity and achieves the goal of improving the thermal power conversion efficiency of internal combustion engines.
At present, the R&D team has turned to the promotion and application of new internal combustion engine energy-saving technologies. Two main types of diesel internal combustion engines have been selected as prototypes for energy-saving design, and efforts are being made to develop high-efficiency marine diesel internal combustion engine technology.
The advantage of the plastic centrifuge tube is that it is transparent or translucent, its hardness is small, and the gradient can be taken out by the puncture method. The disadvantage is that it is easy to deform, has poor corrosion resistance to organic solvents, and has a short service life.
Plastic Centrifuge Tubes have caps, which are used to prevent sample leakage, especially when used for radioactive or highly corrosive samples. It is very important to prevent sample leakage; the tube cap also has a function to prevent sample volatilization. And support the centrifuge tube to prevent deformation of the centrifuge tube. When choosing this point, you should also pay attention to check whether the tube cover is tight, and whether it can be tightly covered during the test, so as to achieve the inversion without leakage;
