[quick news] December 10, 2019: grape skin can be made into green deicing agent for road maintenance

US media: grape skin can be made into green deicing agent for road maintenance according to us daily science website 12 In May, researchers including graduate student Mehdi honalvar Nazari and associate professor of civil and environmental engineering Shi Mingming concluded that their de icing agent containing grape extract had better performance than the commonly used de icing agent, including road salt and the mixture of salt water and beet juice, which is considered to be more environmentally friendly Their results were published in the December issue of the American Journal of civil engineering materials "The beauty of this approach is that it allows us to be flexible," he said We can use the same technology platform in different areas of the country, but depending on the different sources of waste, we can choose different agricultural products " The study was supported by the National Science Foundation, the Washington State Department of transportation, and the U.S Department of transportation Http:// research progress in the conversion and storage of solar energy based on water / oxygen cycle Recently, Dong Shaojun's team of Changchun Institute of Applied Chemistry, Chinese Academy of Sciences, has realized the continuous conversion and storage of solar energy under the integrated system by building a bio photoelectrochemical model based on the water / oxygen cycle, providing a new research idea for the efficient utilization of renewable energy Http://news.bioon.com/article/6747673.html western media: the study found that air pollution can cause diseases such as infection and renal failure According to Western media, a study found for the first time that the aggravation of air pollution is closely related to the outbreak of other diseases besides respiratory and heart diseases The new evidence comes from an article published in the British Medical Journal on the 28th Spain's national daily reported on November 28 that the study analyzed more than 95 million hospitalized patients over the age of 65 receiving medical insurance in the United States within 12 years Comparing the patient data with the PM2.5 particle concentration data, it can be confirmed that each time the air pollution increases, the number of hospital admissions will increase the next day The report says there are some limitations in the study, but many experts point out that it has opened up an interesting way, and it is clear that the incidence rate associated with this air pollution is "underestimated" Http:// does food irradiation harm health? Misunderstood! Irradiation technology is a kind of food processing and preservation technology in the field of food, and it is also one of the cold sterilization technology that we often say But some people think that after radiation treatment of food there is also a risk of harm to the human body, is it true? Jiang Qixing, associate professor of School of food, Jiangnan University and post expert of Jiangsu Modern Agriculture (catfish) industry technology system processing and circulation innovation team, said: "China national standard gb18524-2016 The national food safety standard health code for food irradiation processing stipulates the definition of food irradiation: the irradiation process that can inhibit germination, delay or promote maturity, insecticidal, bactericidal, sterilization and antiseptic by using the radiation chemical and radiation biological effects produced by ionizing radiation in food " Therefore, irradiated food is safe and reliable, and can be eaten at ease Radiation only plays a role in sterilization, and has no adverse effect on human growth, development and genetics Https://tech.gmw.cn/2019-12/04/content_33373818.htmstudy reveals the structural basis for the stability of respiratory chain complex III in extreme environment Recently, Sun Fei research group of Institute of Biophysics, Chinese Academy of Sciences and Hartmut Michel research group of Institute of Max Planck, Germany, published in the International Journal angelwandtechemie International Edition ）A cover article was published in the magazine This work is the first to report the natural state of respiratory chain complex III from thermophilic bacteria and the high-resolution frozen electron microscope structure after binding the inhibitor A series of new structural features that can significantly enhance the stability of protein have been identified, thus revealing the structural basis of respiratory chain complex that can still play a stable physiological function in extreme environment at the atomic level The research is supported by NSFC and national key research and development projects Data collection and other work have been greatly supported and helped by the Institute of Biophysics biological imaging center (Huang Xiaojun, Zhu Boling, etc.) http://news.bioon.com/article/6747670.html
