[quick news] on September 20, 2019, Chinese scientists made significant progress in the field of organic long afterglow luminescence

Chinese scientists have made great progress in the field of organic long afterglow luminescence Recently, Huang Wei, academician of the Chinese Academy of Sciences and chief scientist of the Flexible Electronics Research Institute of Northwestern Polytechnic University, and an Zhongfu, Professor of the Advanced Materials Research Institute of Nanjing Polytechnic University, led the team to make another significant breakthrough in the field of organic long afterglow luminescence, designing and developing a series of new long afterglow polymer materials Relevant results were published online on September 18 in nature communication, and Huang Wei and an Zhongfu were the corresponding authors of the paper Long afterglow luminescent materials are widely used in night emergency indication, instrument display, optoelectronic devices, national defense and military fields, especially in recent years, with its long life, large Stokes displacement and rich excited state properties, they are used in anti-counterfeiting, encryption, biological imaging and other cutting-edge scientific fields Https:// dolphin skin and body found high concentrations of pollutants, mercury content reached the highest level in the history of marine pollutants to deep sea waters, sediments and animal communities spread depth and breadth, far more than previously expected Belgian scientists have investigated one of Europe's largest coastal dolphin populations and found that there are a large number of "mixed" pollutants - Mercury, PCBs, dioxins and industrial fluids - in whale fat and skin of these dolphins Mercury levels in the 82 channel dolphins are among the highest ever found High concentrations of "mixed" pollutants in dolphins are thought to move through the mother to the next generation According to the researchers, the methods that can be adopted now include the designation of the Bay as a special reserve, so as to protect one of the largest dolphin populations in Europe as much as possible Http://digitalpaper.stdaily.com/http_ Div = - 1 scientists have developed stronger waterproof materials inspired by the puffer fish Although the thorn of the puffer fish can help it prevent predators, it will not be waterproof Nevertheless, scientists have now replicated its structure to create a stronger waterproof material than before Researchers at Japan's National Institute of materials began to replicate them on a smaller scale They first made tiny needle like structures out of zinc oxide, and then added siloxane polymers to enhance elasticity The resulting material consists of a matrix of elastic needles - which not only has a surface coating - but also has a high degree of hydrophobicity (water resistance) In addition, it remains of high quality even after more than 1000 bends and abrasions A research paper led by Yoshihiro Yamauchi and Masanobu Naito was recently published in the journal ACS applied materials and interfaces Https:// microorganisms in the human body and the way of birth According to a medical study published on the 19th of the British Journal of nature, the microorganisms in the human body are related to the way of birth: the intestinal microflora of cesarean babies is easy to change, and they are more vulnerable to colonization by potential pathogens This is the largest known project of its kind, confirming that the mode of delivery is the main factor determining the intestinal flora in the first few weeks of human life Trevor Laurey, a scientist at the Wellcome Sanger Institute in the UK, and his colleagues sequenced the whole genome of 596 full-term infants born in the hospital They found that about 83% of cesarean babies carried potential pathogenic bacteria, while only about 49% of babies born naturally Http://digitalpaper.stdaily.com/http_ HTM? Div = - 1 inactivation of setd3 protein can prevent the common cold US researchers' research on human culture and mice shows that temporarily disabling single protein in human cells can protect people from the common cold and other viral diseases Relevant research was published on the website of nature microbiology recently At least half of colds are the result of rhinovirus infection Rhinovirus is highly mutated, so it can quickly develop drug resistance and avoid immune surveillance caused by previous infection or vaccination Researchers at Stanford University and the University of California, San Francisco, have found a way to prevent multiple enteroviruses, including rhinoviruses, from replicating in human cells or mice http://digitalpaper.stdaily.com/http_
