[quick news] 8 years of joint research on July 15, 2019 - "super band aid" R & D success

It took eight years to jointly tackle the key problem - "super band aid" was successfully developed A few days ago, Tianjin University - xinlega biomaterial Joint Research Center released a "new biomacromolecule emergency hemostasis material", which can be used in 1-3 days when a large blood vessel is ruptured and bleeding It can stop bleeding completely within minutes; it can easily separate from the wound and avoid secondary bleeding after hemostasis It is a veritable "super band aid" The new material looks like an ordinary sponge, only a few millimeters thick, and has many evenly sized holes This kind of material is light and thin In case of massive blood vessel bleeding, as long as this "sponge" is covered on the wound, the water in the blood will quickly enter the new material, and the blood components with coagulation such as platelets will be concentrated on the surface of the damaged blood vessel and the "sponge", so as to achieve the purpose of rapid hemostasis, just like a "super band aid" Http://baijiahao.baidu.com/s?

Div = - 1 The preliminary evaluation of 2019 National Science and technology award has been announced through the project, and the preliminary evaluation of 2019 National Science and technology award has ended According to the detailed rules for the implementation of the regulations on science and technology awards of the people's Republic of China, 53 items of National Natural Science Awards, 56 items of national technology invention awards and 152 items of national science and technology progress awards are published on the relevant websites 20 special projects of National Technology Invention Award and 43 special projects of national science and technology progress award passed the preliminary evaluation will be published internally in the entrusted management unit, nomination unit and project completion unit Http:// Menuid = 25 & ContentID = 1611 new technology developed by Chinese scholars: only "very small" blood can be used to detect the content of heavy metals in human body environmental pollution can lead to the accumulation of mercury, lead, cadmium, arsenic and other heavy metals in human body, resulting in chronic poisoning Recently, Huang Xingjiu research group of Hefei Institute of intelligent machinery, Chinese Academy of Sciences has creatively applied FET chip technology to this field and designed a new type of chip Through simulation technology and related theory, they analyzed the relationship between the different "assembly arrangement direction" of channel materials and performance accurately, and equipped the chip with molecular probes, and finally realized the "super sensitive" detection Experiments show that the minimum detectable level of the chip is 10 nmol / L and the detection response speed is less than 1 second Http:// white paper of China's dairy industry was released: the qualified rate of China's dairy products supervision sampling inspection was more than 99% for three consecutive years, the 10th China dairy industry conference was held in Tianjin on December 14 During this time, China dairy white paper "China's dairy industry" was officially released by China Dairy Association According to the data summarized in the white paper, the qualified rate of supervision sampling inspection of dairy products in China has been more than 99% for three consecutive years, melamine in infant formula milk powder has been detected zero for 10 consecutive years, and aflatoxin M1 in dairy products has not been detected for five consecutive years In 2018, the qualified rate of dairy products samples inspected by the State Food Safety Supervision was 99.8%, which was the highest class of food The qualified rate of infant formula milk powder sample reached 99.9% http://society.people.com.cn/n1/2019/0715/c1008-31233010.html
