    Last year, China authorized 453000 invention patents It was learned from the meeting of directors of the national intellectual property office that in 2019, China authorized 453000 invention patents, 1582000 utility model patents and 557000 design patents; the number of invention patents per 10000 population in China reached 13.3, fulfilling the target task set in the 13th five year plan ahead of time; 6.406 million registered trademarks, and the number of effective trademark registrations reached 25.219 million, with an average of 49 patents The market main body owns 1 registered trademark; 2385 geographical indication protection products and 5324 registered geographical indication trademarks have been approved in total; the total financing amount of patent and trademark pledge has exceeded 150 billion yuan Http://paper.people.com.cn/rmrb/html/2020-01/07/nw.D110000renmrb_20200107_5-02.htm "foam tiles" at 1000 degrees high temperature and no deformation, the Chongqing Academy of green science and technology of the Chinese Academy of Sciences has released a self-developed green new building material foam ceramic, which not only can keep warm, moisture-proof, sound insulation, but also fire prevention, and does not deform at 1000 degree high temperature "Foam tiles" look like volcano stones, and they do not burn at the temperature of alcohol at 500 degrees Celsius, and the temperature on the other side is only forty or fifty degrees Celsius Cui Yuehua, director of the project group and researcher of Chongqing Green Intelligent Technology Research Institute of the Chinese Academy of Sciences, introduced that the results can be adapted to the harsh environment by adjusting the components of foam ceramics, such as the temperature of dilute sulfuric acid and cold and hot mutations produced in the desulfurization tower The ultra light density enables it to float on the water surface for a long time, which can be used for life-saving equipment or marine breeding and planting applications, and it is also a high-quality material for heat preservation, flame retardant and sound insulation for future planning buildings in China Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-01/08/content_438210.htm? Div=-1 can be both antibacterial and anti-inflammatory, a new type of hydrogel that can cure wounds Researchers like Manuky Bta of Lund University in Sweden developed a hydrogel, which contains a kind of peptide derived from hemagglutination enzyme, that is, TCP-25, which can kill bacteria and reduce inflammation Hydrogels are effective for Staphylococcus aureus, Pseudomonas aeruginosa and clinically isolated bacteria in vitro, and can be used for treatment of subcutaneous infection and partial wound infection in mice The results showed that the functional hydrogel containing anti-inflammatory antimicrobial peptides is a promising wound healing agent Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-01/08/content_ HTM? Div = - 1 block superbugs my scientists find ideas from antimicrobial peptides Researcher Lai Ren and associate researcher Zhang Zhiye of natural drug functional proteomics research group of Kunming Institute of zoology, Chinese Academy of Sciences designed and modified ZY4, an antibacterial peptide with strong antibacterial activity, high stability and low toxicity It provides a good candidate drug molecule for the transmission and infection of Acinetobacter baumannii and Pseudomonas aeruginosa, and also provides a new strategy for the design of high-efficiency and low toxicity antimicrobial peptides Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2020-01 / 08 / content_ HTM? Div = - 1 it only takes 3 days for 3D printing to "Customize" the knee joint We learned from the national 3DP joint replacement and rapid rehabilitation forum and the 2019 medical 3DP annual meeting of Chongqing additive manufacturing association that 3D is used in China Printing porous tantalum prosthesis has taken the lead in clinical application, and this technology has taken the lead in the world The computer-aided design and 3D printing of personalized graft treatment can make the prosthesis fully fill and reconstruct the defect bone structure, better help patients recover and reduce side effects Wu Xianzhe, director of the Institute of Optics and mechanics of the Chinese Academy of heavy Sciences, introduced that the team established a rapid design method of porous tantalum personalized prosthesis based on medical imaging technology through technical research, and established a standard digital model database of hip knee prosthesis, with a total of 103 kinds of model data, which can be used in the process of personalized prosthesis design and implant scheme design http://news.bioon.com/article/6748759.html
