On November 3, the 2020 National Science and Technology Awards Conference, an annual hall-class event in China's science and technology circles, was held in Beijing.
Henan Province has achieved another good result, winning a total of 17 national science and technology awards, including 3 national technological invention awards and 14 national scientific and technological progress awards. Among them, Henan Province has hosted 4 projects and participated in 13 projects.
Of the four projects completed by Henan Province, the project "Key Technology and Engineering of High-performance ITO Target Materials for Flat Panel Displays" presided over by Academician He Jilin of Zhengzhou University won the second prize of the National Technological Invention Award, and the project "Key Technologies and Their Applications for Efficient Development of Reservoir Coalbed Methane under Complex Geological Conditions" presided over by Professor Cao Yunxing of Henan Polytechnic University won the second prize of the National Science and Technology Progress Award.
Come, follow the top news Henan Business Daily reporter to understand these cutting-edge technologies born in Henan.

Breaking foreign monopolies and forcing foreign suppliers to cut prices by 75%
In the Internet era, mobile phone screens and computer screens have to meet people every day. An award-winning project in Henan at the National Science and Technology Awards Conference is related to the production of screens.
The project "Key Technologies and Engineering for the Preparation of High-performance ITO Targets for Flat Panel Displays" led by the team of academician He Jilin of Zhengzhou University won the second prize of the National Technological Invention Award in 2020.
(Target Research Results)
In the production process of flat panel displays, ITO targets are indispensable. ITO target is an abbreviation for indium tin oxide target, which is used to plate a transparent, conductive film, or ito film, on a glass substrate or organic film through a magnetron sputtering process. ITO film is currently the best light transmittance and conductivity in oxide film, so ito target is a necessary upstream material for display panels.
The top news Henan Business Daily reporter learned that although China is a big country of indium resources, 80% of the target material market has been monopolized by Japan and South Korea, and the current production of ITO targets in China can only meet the low-end demand. According to reports, China's target research and development lags behind 20 years, 28 companies have an annual output of less than a Japanese Mitsui family, can not burn out a large target, flat panel display manufacturing back to people's sniffles.
The team of academician He Jilin of Zhengzhou University has made a breakthrough to solve the problem of "card neck" of key technologies and equipment in the whole process of high-performance ITO target preparation, filling the domestic gap and realizing the independent innovation of overall process technology. Its key technical indicators have reached the international advanced level, and it has also won the first prize of China Nonferrous Metal Industry Science and Technology Award in 2019.
The relevant person in charge of Zhengzhou University introduced to the top news Henan Business Daily reporter that the project product has been successfully applied to the high-generation TFT line of the world's largest panel enterprise BOE for the first time in China, breaking foreign technical barriers and completely replacing imports. The technology forced Japan's ITO targets to slash prices, by more than 75 percent. In terms of economic benefits, the project has promoted new sales of 105 million yuan, profit of 9.53 million yuan, new application benefits of 4.74 billion yuan, and profits of 510 million yuan in the past three years.
In addition, in the process of research and development of the project, a high-level target research and development platform and team have been established, a group of leading and backbone talents have been trained for the industry, the localization process of key substrates for China's strategic emerging display industry has been promoted, and a demonstration and leading contribution has been made to the target material "Made in China" to "Created in China".
The Henan professor's technology solves the problem of coalbed methane mining
The project "Key Technologies and Their Applications for Efficient Development of Coalbed Methane in Reservoirs under Complex Geological Conditions" presided over by Professor Cao Yunxing of Henan Polytechnic University won the second prize of the 2020 National Science and Technology Progress Award.
To understand this project, we must first understand the relationship between coal-bed methane and natural gas. Natural gas is one of the important low-carbon energy sources, from small people cooking, bathing, heating, to clean power generation, industrial production have natural gas figures.
Coal-bed methane is a gas resource associated with and symbiotic with coal, which refers to the hydrocarbon gas stored in the coal seam, with methane as the main component, which belongs to unconventional natural gas (conventional natural gas is usually oil field gas and gas field gas).
The henan business daily reporter learned that China currently has natural gas reserves of about 30 trillion cubic meters in rock formations within 2,000 meters of the surface. However, China's natural gas has long depended on a large number of imports, and one of the important reasons is that the extraction technology is relatively immature and the extraction efficiency is not high. Especially in coal-bed methane with complex geological conditions. For example, some coal-bed methane in Xinjiang, Shanxi and other places, due to the complex geological environment, have repeatedly tried for more than ten years and have not been successfully exploited.
Professor Cao Yunxing, director of the Coalbed Methane Geological Engineering Research Center of Henan Polytechnic University and director of the Henan Provincial International Joint Laboratory of Unconventional Energy Geology and Development, and his team have developed technologies over a period of 13 years, which will play an important role in the field of coalbed methane mining.
"Prescribe the right medicine and treat it dialectically." Our method can be described by Zhang Zhongjing's theory of Traditional Chinese medicine. Professor Cao Yunxing described it to the top news Henan Business Daily reporter.
He explained that this set of technologies is mainly suitable for coal-bed methane in geologically complex environments, which is a complex system that can achieve efficient collection according to different geological conditions. In the same geological environment, the collection efficiency can be improved by 5-10 times compared to conventional methods.
For example, the development of coal-bed methane in Xinjiang has been unsuccessful for 13 years. Later, Professor Cao Yunxing's team used their methods to successfully mine. In addition, the technology is used in the development of coal-bed methane in Jincheng, Changzhi and other places in Shanxi.
It is also worth noting that the mining of coal-bed methane can also have a multiplier effect. Coal-bed methane is also commonly known as "gas", when the concentration of coal-bed methane air reaches 5%-16%, it will explode in the presence of an open fire, which is the root cause of the coal mine gas explosion accident. Therefore, before coal mining, the mining and pumping of gas in the coal seam can greatly reduce the amount of air exhaust gas, reduce the ventilation requirements of coal mines, reduce the explosion rate of coal mine gas will be reduced by 70% to 85%, and improve the safe production conditions of miners.
"Next, we will explore new mining methods for more different geological environments." Professor Cao Yunxing said that he and his team will be committed to making new contributions to the country's clean energy and national strategic resources.
