The gastric cancer is one of the most common malignant tumors of alimentary canal. According to statistics, the incidence of gastric cancer in China ranks third among malignant tumors, and the fatality rate ranks second. Because early gastric cancer has no specific symptoms and signs, a few people will have nausea, vomiting or upper gastrointestinal symptoms similar to ulcer disease, but it is difficult to attract enough attention. Most patients are in the advanced stage at the time of discovery. Therefore, identifying high-risk groups and improving the early diagnosis rate of gastric cancer are the key to improve the survival rate of patients.In recent years, with the improvement of deep learning, machine learning algorithms, hardware levels and databases, artificial intelligence technology has ushered in the third wave of development, which can provide powerful assistance for medical diagnosis in the medical field. This research team constructed a smart image recognition and diagnosis generation system for gastric cancer.

Brief introduction of project resultsAs an important part of supercapacitor, electrode material is one of the key factors restricting the performance of supercapacitor. In theory, the specific surface area of carbon materials is proportional to the specific capacitance of supercapacitors, so the specific surface size of carbon materials is one of the important indicators to measure the electrochemical performance of supercapacitors.At present, the electrode material of supercapacitors is mainly commercially available activated carbon, whose specific surface area is mainly between 1500 and 2000㎡/g, and the lack of specific surface of carbon materials seriously limits the energy density of supercapacitors. At present, we have invented a new activated carbon preparation process, combined with this process to improve the traditional activated carbon preparation equipment, and successfully prepared high-quality activated carbon with a small ash (< 0.3 wt.%), high specific surface area (> 3500 ㎡/g), good electrical conductivity (> 500 S/m), and reasonable aperture distribution.At present, the carbon material has been pilot-produced at the hectogram level on the improved equipment. The capacity of the supercapacitor constructed by using the activated carbon as the electrode material of the supercapacitor is 50% higher than that of the commercial supercapacitor, and has a better magnmagnation and wide temperature range (-100℃-60℃). Patent Application No. 201810512630.5 for physical activation preparation method of ultra-high specific surface area microporous carbonPatent application No. 201810512691.1 for a preparation method of ultra-low temperature and high capacity supercapacitorScope of application and market prospectsHigh performance supercapacitor electrode material.Investment estimates1.2 million.Means of cooperationJoint development.

Technical fieldThe invention belongs to the field of nanocomposite material preparation, in particular relates to a preparation method of graphene (GE)/γFe2O3 composite photocatalyst modified by CdS nanoparticles.Technical backgroundSemiconductor photocatalysis is a hot research direction in the intersection of materials chemistry and environmental chemistry. Photocatalysis technology can degrade most organic pollutants at normal temperature and pressure without secondary pollution, and has become a promising method for environmental pollution control. The core of photocatalytic technology is photocatalytic materials, and traditional photocatalytic materials for metal oxides or sulfide semiconductor compounds, which are limited by their own properties; photocatalytic performance is generally low.In recent years, the coupling of two or more kinds of semiconductors to form semiconductor heterostructures has received extensive attention from researchers. It has become a developing trend to construct all-solid-state Z-type band structure composites according to the different positions of semiconductor conduction and valence bands. All-solid Z-type band structure uses electrons on semiconductor A guide band to combine with holes in semiconductor B valence band through electronic intermediation, leaving holes on semiconductor A and electrons on semiconductor B, and the remaining electrons and holes have strong reduction and oxidation capabilities. In addition, this structure can promote the effective separation of photogenerated electron-hole pairs. The catalytic performance of semiconductor is greatly improved.Graphene (GE) is a new two-dimensional carbon material that has developed most rapidly in recent years. In addition to many advantages of traditional carbon materials such as large specific surface area, high chemical stability, and good adsorption capacity, it also has special properties such as perfect quantum Hall effect, unique quantum tunneling effect, and bipolar electric field effect due to its unique structure. The invention selects γ-Fe2O3 and CdS with matching band gap as semiconductor A and B respectively, and uses graphene as electronic intermediary to construct γ-Fe2O3/GE/CdS composite photocatalyst, and prepares a Z-type structure composite photocatalytic material with excellent performance, which can be used for visible light degradation of organic pollutants.Content of inventionFirst, cubic Prussian blue (PB) nanoparticles were synthesized by hydrothermal method. Then the PB particles were ultrasonically dispersed in deionized water, and polyacrylamide hydrochloride was added to make the PB particles positively charged. Add uniform graphite oxide dispersion and cadmium nitrate solution successively and stir. Finally, the sodium sulfide solution is added, stir, and the product is collected. The product was heated to 350℃ at the rate of 2℃min1 in an argon atmosphere and kept for 2 hours to obtain the final product. The composite is a good visible light catalyst and has photocatalytic degradation effect on Rhodamine B.
