Chinese contemporary inventions:
Artificial insulin: Artificial insulin is the first biologically active substance synthesized by humans. Its chemical structure is exactly the same as natural bovine insulin, and its chemical essence is A polypeptide molecule composed of 3 peptide chains and 51 amino acids. This substance can be used to treat diabetes, among other things. The invention was nominated for the Nobel Prize in Physiology or Medicine, but failed to win because the winner could not be determined.
Artificial bezoar: The main ingredients are bilirubin, cholic acid, cholesterol, inorganic salts, etc. It has the functions of clearing the heart, eliminating phlegm, resuscitating the mind, cooling the liver, calming wind, and detoxifying. The yield of natural bezoar is extremely low and the price is far beyond the reach of working class people. The price of artificial bezoar is much lower than that of natural ones. The price of Chinese patent medicines containing artificial bezoar (such as Bezoar Jiedu Tablets, etc.) is the same as that of most proprietary Chinese medicines, but the efficacy of artificial bezoar is not as good as that of natural ones.
Artemisinin: The anti-malarial drug of artemisinin complex is found in the Artemisia annua plant, which belongs to the same genus as Artemisia annua. However, artemisinin was later discovered by a Chinese research team in 1972 and used to treat multi-drug-resistant strains of Plasmodium falciparum malaria. With good results.
Hybrid rice: In 1973, agricultural scientists headed by Yuan Longping developed a new type of rice called hybrid rice. Hybrid rice has proven to be extremely valuable where arable land is extremely limited and is adopted by many Asian and African countries.
Magnetic levitation wind turbine: In 2006, a new type of wind turbine using magnetic levitation was exhibited at the Asian Wind Energy Conference in Beijing. Scientist Li Guokun is the chief researcher of the new magnetic levitation wind turbine. Li Guokun said that traditional wind turbines require high wind speeds to start due to friction caused by bearings. The new frictionless magnetic levitation wind turbine starts with wind speeds of just 1.5 meters per second, which is expected to cut wind farm operating costs in half.
