The latest achievements of the key special project "Research on the causes and control technology of air pollution" are applied to the new generation of carbon fiber metro car body coating volatile organic compounds (VOCs), which are important precursors of air secondary particles and ozone The coating industry accounts for a considerable proportion of VOCs emissions in China For this reason, the research on the causes of air pollution and control technology focuses on the research and development of volatile organic compounds (VOCs) control and alternative technologies and equipment in key industries, and supports the project of "research and industrialization of green waterborne industrial coatings and coating technology" in the coating industry The project is led by beautiful special (Beijing) Environmental Materials Technology Co., Ltd., with the participation of CRRC Sifang Co., Ltd., CRRC Sifang Research Institute, CRRC Sifang Co., Ltd., process Institute of Chinese Academy of Sciences, Harbin University of technology, Beijing University of chemical technology and other units, aiming to comprehensively promote the technology upgrading of green environmental protection industry in the paint and coating industry and break the high level The key technology field of end water coating is controlled by the situation of foreign enterprises Since the project was launched in 2016, great progress has been made in green environmental protection coating materials and processes Water-based coating materials and water-based anti-corrosion coating materials for rail vehicles that meet the requirements of EU environmental protection have been developed, and application tests have been carried out Http://www.most.gov.cn/gnwkjdt/201810/t20181010_.htm intelligent therapy for liver fibrosis discovered by China University of science and technology Recently, the international academic journal "American Chemical Society · nano" published online the research results of Liang Gaolin and Lian Zhexing research group of University of science and technology of China, reported a new strategy to enhance the anti fibrosis effect, and showed a better therapeutic effect on liver fibrosis than the current clinical strategy on the animal model Liang Gaolin's research group designed a gelling factor precursor with a chemical structure formula of 1-dex-p, and proposed a new strategy of tandem enzyme-controlled self-assembly and slow release of dexamethasone Using this strategy, they combined with the project of Lian Zhexing and found that the precursor drug 1-dex-p showed stronger anti fibrosis effect in vitro and in vivo compared with free dexamethasone In vitro digestion and cell experiments showed that 1-dex-p was first dephosphorized by alkaline phosphatase and transformed into gelatinizing factor 1-dex, and then self-assembled into nanofiber 1-dex The fiber can then be hydrolyzed by esterase, releasing dexamethasone slowly, and then transformed into a new kind of nanofiber 1 Animal experiments show that the biocompatible 1-dex-p has a stronger anti fibrosis effect than dexamethasone Https://pubs.acs.org/doi/10.1021/acsnano.8b04143 the use of a new base editor in vivo is expected to treat genetic diseases of newborn parents may be aware of a metabolic disorder called phenylketonuria In Switzerland, all newborns are screened for the genetic disease Children with phenylketonuria have been found to need a special diet so that phenylalanine does not accumulate in the body Too much phenylalanine can slow mental and motor development If the genetic disease is not treated in time, children may suffer from severe mental disability In a new study, researchers from the Federal Institute of technology in Zurich and the University of Zurich, Switzerland, used a method to correct two copies of the mutated gene in hepatocytes, thereby curing the disease Their research has been successful in mice The results were published in the journal Nature Medicine Https://www.nature.com/articles/s41591-018-0209-1 less TV and more fruits and vegetables can reduce the risk of genetic obesity A study on environment and genetic obesity by University of London found that children living in families who are used to eating more fruits and vegetables and watching less TV have a lower risk of obesity due to genetic factors; on the contrary, genetic factors account for a higher proportion of obesity risk The data came from 925 pairs of identical and fraternal twins In the study, the influence of heredity and environment on children's early weight locus was evaluated The results show that the effect of genes on obesity may vary with the environment, and the effect of healthy family environment on BMI of children can surpass that of heredity Https://www.dailymail.co.uk/health/article-6257787/a-health-home-cut-children-genetic-objectivity-risks-half-study-finds.html China's first large-scale solar thermal demonstration power plant was officially put into operation recently, China Guanghe group announced in Beijing that China's first large-scale commercial solar thermal demonstration power plant - CGNPC Delingha 50 The megawatt solar thermal demonstration project was officially put into operation Solar thermal power generation is clean and environmental friendly Compared with photovoltaic power generation, it has the advantages of continuity and stability, which can make up for the shortcomings of photovoltaic power generation to a certain extent, and has the potential to become the basic load power supply "The formal operation of Delingha project marks that CGNPC has the core capability of system integration of large-scale solar thermal power stations and the capability of building China's solar thermal industry chain." Yuan Changhong, a cnpec spokesman, said the Delingha project and the national energy and solar thermal research and development center will provide important support for China's large-scale promotion of solar thermal power generation projects in the future http://www.xinhuanet.com/fortune/2018-10/10/c_1123541019.htm
