Eight sci-tech achievements in Chongqing 
Quick-coagulation cotton: multi-functional super-absorbent fiber
Biochip-based detection technology for benign and malignant nodules
Intelligent control system for sewage treatment based on the Internet of Things
Glass micro-nano structure molding technology
Hyperspectral computational imaging system
New-generation foundation interference radar technology for landslide monitoring
A series of implementation programs for low-carbon energy technology industrialization (by the Chinese Academy of Sciences)
Graphene series products (by Chongqing Yingnuo’er Graphene Technology Co., Ltd)

Quick-coagulation cotton

According to Bio-road, an R&D team of biomedical materials from Southwest University, who created the quick-coagulation cotton, 60% of the injured died from excessive loss of blood nearly in all types of accidents. Even in clinical operations, deaths caused by excessive blood loss are common.

The cotton will turn into “jelly” after quickly absorbing the water in the blood so as to stop bleeding rapidly. It has been proved that cotton is highly safe, where it can be directly absorbed without removal in animals after being degraded from cellulose into monosaccharide molecules.

“In the huge market for rapid hemostatic materials in China, foreign products account for 80% of the share, and their price is 3–5 times that of domestic products,” said Yu Kun, a member from Bio-road at Southwest University.

As their quick-coagulation cotton has obtained six national invention patents, a 100,000-grade purification GMP workshop covering an area of 800 square meters has been built.

Featuring a short production process and lower costs than foreign products, quick-coagulation cotton will be widely used in the future.

Hyperspectral computational imaging system

“Low-cost and high-performance hyperspectral imaging equipment is urgently needed in the fields of environmental monitoring, precision farming, public security, and medical diagnosis to realize accurate monitoring with map fusion,” said Professor Xu Tingfa from Beijing Institute of Technology Chongqing Innovation Center. The hyperspectral computational imaging system was created by his team, where it attracted much attention.

Xu continued, spectral computing imaging technology serves as one of the trends of future image development, and spectral image data can simultaneously show the material properties and spatial information of objects.

Xu raised an example; if there is a green belt where people can’t tell whether the greenery is real or not, a spectral imaging device can do it with naked eyes and color cameras.

At present, the team is cooperating with Chongqing Institute of Geology and Mineral Resources in accurate monitoring of ecological restoration and groundwater quality.

In fact, relevant technical achievements also have broad application prospects in industrial visual inspection and biomedical diagnosis.

“We hope to find partners to jointly expand application scenarios of our achievement through the roadshow and matchmaking meeting,” Xu added.
