[quick news] September 27, 2018 graphene: let "scientific fashion" return to the material itself

Graphene: let "scientific fashion" return to the material itself At the closing ceremony of 2018 China International graphene Innovation Conference in Xi'an, Norbert Francis, director of EU graphene flagship program standards committee, formally read out the Xi'an declaration According to Li Yichun, Secretary General of China graphene industry technology innovation strategic alliance, the declaration jointly signed by representatives of institutions from more than 20 countries is a witness to China's dominant position in graphene industry At present, the R & D advantage of graphene is still occupied by European countries, but China's industrial development is more dynamic and has formed industrial breakthroughs in some application fields, Li said Http://news.scienceet.cn/sbhtmlnews/2018/9/339545.shtm 3D printing skull slice helps dog regain new life recently Ontario Veterinary College operated on patches, a dachshund with head tumor, with the help of 3D printing technology Doctors have successfully removed the huge tumor growing into the skull, and implanted a customized 3D printed titanium skull piece The implant fits perfectly with the skull wound, saving patches' life The application of 3D printing technology greatly shortens the operation time, and the practical application of related technologies will provide valuable information for human medicine and lay the foundation for the development of personalized medicine Https:// the new nano coating can make industrial ceramics free from thermal shock due to its ability to withstand extreme environment, and ceramic materials are used in nuclear, chemical and power generation industries However, at high temperatures, ceramics are prone to fracture due to thermal shock caused by rapid temperature change events, such as cold water droplets contacting hot surfaces In a novel interdisciplinary approach, engineers from the University of New Mexico in the United States reported a cheap, simple hydrophobic coating to prevent thermal shock of ceramics in the journal progress of the American Physics Federation (AIP) publishing group The researchers used the same materials, but controlled the heat transfer, so that the ceramics experience a more moderate temperature gradient, reduce the tensile stress, thus greatly improving the thermal shock behavior Https://publishing.aip.org/publishing/journal-highlights/improved-thermal-stock-resistance-industrial-ceramics organ chip research continues to attract international attention Recently, the Royal Society of chemistry published the special issue "excellent research - 100 women in the chemical industry", which shows the high-quality research work of 100 women scientists from 23 countries Qin Jianhua, a researcher of Dalian Institute of Chemical Physics, Chinese Academy of Sciences, is one of the research results of organ chip Qin Jianhua's representative work is to use organ chip technology to construct an innovative diabetic nephropathy model to simulate the complex and dynamic pathological changes of glomeruli in vivo, so as to solve the problem that the in vitro model is difficult to reflect the physiological function of organs The research was published in lab on a chip, a famous journal in the field of organ chip, and was rated as a hot article Natural review · drug discovery and natural review · materials cited it as a typical case of organ chip They thought it was an important breakthrough to the traditional simple cytology method and provided a new and more reliable research system for complex disease research and drug development Https://pubs.acs.org/doi/10.1021/acsbiomaterials.8b00653 "gene scissors" can lead to the demise of mosquitoes According to a study published online in the British journal Nature Biotechnology, a new "gene driven" mechanism can lead to the complete collapse of captive mosquito populations carrying malaria In the experiment, no mutation occurred to prevent the spread of "gene drive", making it the first "gene drive" that is expected to take effect in the field Previous experiments have shown that a "gene drive" designed to reduce the reproductive capacity of female mosquitoes can be spread in captive mosquitoes, reducing the population size However, subsequent experiments found that mosquitoes eventually developed resistance to this "gene driven" and prevented further transmission, which means that the strategy is not suitable for killing mosquitoes in the wild https://
