The teacher of the team has another identity: the shareholder of Hubei Di Jie Membrane Technology Co., Ltd., with * * * holding 50.4%.
As a rare silicon carbide ceramic production technology enterprise with completely independent intellectual property rights in China, this company (with an investment of 38 million yuan) will take the lead in mass production of silicon carbide ceramic membranes in China in three months.
Previously, a group (8 patents) developed by the team invested in Hubei Di Jie Membrane Technology Co., Ltd. at a price of 210.28 million yuan. According to relevant policies and regulations, the school will reward the R&D team with 90% of the income, namely 1.9 1.52 million yuan.
What happened behind eight patents inciting 50.4% of the shares?

Turbid red bayberry wine flows through an experimental device made of silicon carbide ceramics and becomes clear after a few minutes; Take a sip and it will taste sweeter and more mellow. In the laboratory, team members gave this demonstration to China Youth Daily and Zhongqing Online reporter.
This gray cylinder device is inconspicuous at first glance. "The surface looks smooth, but in fact all the holes are distributed." Ji Jiayou, one of the team leaders and an associate professor in the College of Materials Science and Engineering, compared this device to a "sieve": raw liquid or dusty air flows at high speed in the membrane tube under pressure, and then pure air or liquid flows out of the membrane, and particles are intercepted by the membrane, thus achieving the effects of separation, purification and concentration.
But these "sieve holes" are invisible to the naked eye.
The diameter ranges from 0.04 micron, 0. 1 micron and 0.5 micron to 1 micron and 3 micron (1 micron is equivalent to 1 millionth of a meter). Ji Jiayou made an analogy: 0.04 micron is equivalent to one thousandth of the diameter of a hair.
This seemingly ordinary "sieve" is made by a special process at high temperature, which can effectively filter out harmful substances in a highly corrosive and easy-to-deposit environment.
The ceramic membrane research team spent nearly four years developing, perfecting and transforming this achievement.
Starting from 20 13. When an alumnus of Wuhan Institute of Technology visited a membrane separation technology exhibition abroad, he brought back a small piece of silicon carbide ceramic membrane products.
At that time, the domestic membrane separation process, the finished product is another ceramic membrane. But its alkali resistance is not enough, and its flux is not enough.
Over the years, the School of Materials Science and Engineering of Wuhan Institute of Technology has accumulated some professional achievements and scientific research achievements in silicon carbide ceramic materials. Teachers all know that silicon carbide ceramic membrane has excellent properties such as acid and alkali resistance, high temperature resistance, large flux and easy cleaning, and its products can be widely used in the treatment of industrial wastewater and flue gas, in addition, it can also be used in food, beverage, pharmaceutical, chemical, mining, swimming pool water treatment and other fields.
However, at that time, as the highest-end product in the ceramic membrane field, it was a fact that all the silicon carbide ceramic membrane materials needed in the domestic water treatment field depended on imports. Prices and supplies are monopolized by foreign countries.
This situation deeply touched the teachers in the college. "People have made products, why should technology lie in the laboratory and sleep? If the transformation is successful, it is expected to break the foreign monopoly and fill the domestic gap. " Ji Jiayou said.
Several professors and associate professors hit it off: set up a team to develop and improve the silicon carbide ceramic membrane technology and turn it into products!
