The Innovation Center of Tsinghua Holdings Co is displaying six of its high-tech projects at the ongoing 19th China Beijing International High-Tech Expo.
The six projects were achieved through the technological research support from Tsinghua University. The center commercializes the high-tech research results from the university and provides support for students' innovative ideas.
Here are the highlights of the six projects:
Heavy-duty gas turbines
One of China's national strategies is to research and develop gas turbines that can turn coal into gas as the country grapples with a lack of oil and natural gas resources.
Tsinghua University is leading the way in the research of heavy-duty gas turbines and has made achievements in the theoretical research and engineering of gas turbines.
Tsinghua Holdings Co, along with Shanghai Electric and Dongfang Electric Corp, have invested in Beijing Huaqing Gas Turbines and Integrated Gasification Combined Cycle Engineering Technology Corp and Shanghai Puqing Gas Turbines Corp.
Chemical mechanical polishing
Chemical mechanical planarization, a polishing process that uses chemicals and mechanical polishing to remove unwanted conductive materials on a silicon wafer, is one of the key technologies being developed by the Innovation Center.
Luo Jianbin, from the department of mechanical engineering at Tsinghua University, began research into the process in 2000. He was awarded the National Science and Technology Progress Award in 2008.
Organic Light-Emitting Diode
The display technology of the next generation, OLED are flexible and ultra-thin. They are in high demand in consumer electronics, especially for wearable devices.
In 1996, the chemistry department at Tsinghua University began its research into OLEDs.
In 2006, Kunshan Weixinnuo was established in Jiangsu province and created the first Passive Matrix OLED manufacturing line on the Chinese mainland. Kunshan Weixinnuo has maintained a sales volume of up to 250 million yuan ($40.9 million) a year.
Magnetic bearings
With rotating machinery becoming faster, more accurate and more intelligent, there has been a greater demand for high-quality bearings. Traditional mechanical bearings are becoming more obsolete and magnetic bearings used in fans, motors and turbines are becoming more highly sought after because they have high rotational speeds.
In China, the technology for magnetic bearings is still in its research stage.
But the Tsinghua University's research team is currently making gains in researching magnetic bearing technologies. It recently built the 1.2-megawatt high speed permanent magnet machine with magnetic bearing that can create an average rotational speed of 18,000 rpm, a 2,500 kW compression turbine with an average rotational speed of 15,000 rpm, a 4.5-megawatt primary helium circulator with high temperature gas cooled reactor with an average rotational speed of 4,500 rpm and a 1-megawatt magnetic power generator.
Sunlectric Co Ltd
Established on April 29, 2015, Sunlectric Co Ltd is a solar-related hardware enterprise founded by Tsinghua students. Other team members are from Peking University and Beijing University of Post and Telecommunications.
The company focuses on the technological research and product development of photovoltaic solar power.
The owner of 11 core patents and a number of scientific innovation awards, the company was the champion of the 2015 Campus Dark House Award and champion of the Fourth of Hangzhou University Venture Contest.
Catching technology
Catching technology is a 3-D optical materials manufacturer and one of the few companies in the world that is capable of researching 3-D technology, 3-D optical materials manufacturing, 3-D image design and data processing.
