China promotes the development of fuel cell cars

After a visit of China’s Prime Minister LI Keqiang to Japan, the development of hydrogen-based fuel cell cars in China gains momentum. The official development plan now provides for 50,000 vehicles by 2025, and car manufacturers such as BAIC, SAIC, Great Wall Motors and Dongfeng are now involved in the development of hydrogen-powered passenger cars, partially based on free licenses from Toyota, which put this development on the road in 2014 with the Toyota Mirai. The necessary infrastructure for hydrogen production and refuelling is to be created within the framework of a China Hydrogen Fuel Cell Alliance 中国氢燃料电池联盟, and between 2019 and 2021 more than 40 hydrogen refuelling stations are to be set up in the Yangtze Delta around Shanghai alone. Two excellent reviews by JETRO (in Japanese) and by Elektroauto News (in German) cover the outlook for the coming years.

Faux mother of pearl diaphragm improves impact resistance of lithium batteries

Porous polyolefins are widely used as barrier against short circuits in commercial lithium ion battery separators due to their excellent electrochemical stability. However, their porous structure results in poor mechanical properties, especially when the diaphragm is subjected to external local impact. A team of the CAS University of Science and Technology of China has substituted the random structured ceramic nanoparticle layer, presently used on top of the separator, by ion‐conductive porous multilayers consisting of highly oriented aragonite platelets. This nacre‐inspired coating can sustain external impact by turning the violent localized stress into lower and more uniform stress due to the platelet sliding, as shown by good cycling stability under external shock.

Chinese NMPA approves Alzheimer drug based on gut microbiota improvement

Oligomannate (GV-971: sodium oligomannurarate) developed by Shanghai Green Valley Pharmaceuticals was approved by the NMPA as a drug to improve cognitive improvement of patients with moderate Alzheimer disease (AD). The multi-center randomized Phase III study which led to the approval was done for 36 weeks at 34 first-class hospitals in China on a total of 818 patients with mild to moderate AD between ages 50 to 85. The results showed that oligomannate produced a statistically significant improvement in cognitive function after 4 weeks of administration, and the effect persisted. Oligomannate is thought to improve cognitive function by improving dysbiosis of intestinal microbiota, suppressing abnormal increase of intestinal bacterial metabolites, regulating inflammation of the peripheral and central nervous system, and by reducing excessive phosphorylation of tau, resulting in less deposits of amyloid protein. GV-971 was co-developed by Ocean University of China, CAS Shanghai Institute of Materia Medica (PI GENG Meiyuand Green Valley Pharmaceutical Co.

China experiments with trash valuation

China is experimenting with hi-tech waste containers, partly according to the “trash to cash” principle. In Chongqing, the user identifies himself by facial recognition and thus puts the “wisdom container” into operation, which sorts the waste using AI technology or printed QR codes, e.g. on recyclable plastic bottles. In Shanghai, citizens themselves sort by four color codes for recyclable, hazardous, dry and wet waste. In Nanjing, after facial recognition, users can have recyclables sorted out of their garbage and credited to their cash account according to a points system.

State Council publishes National Plan to Contain AIDS

On 13 October, the State Council published a national plan for the control and containment of AIDS for the years 2019-2022 (《遏制艾滋病传播实施方案(2019-2022年)》). The responsible ministry is the National Health Commission (NHC 卫健委), and nine other ministries or departments of the central government are involved, including the Ministry of Education MOE and the Ministry of Science and Technology MOST. 

At the end of 2018, there were 1.25 million HIV-infected persons registered in China; in 2017 alone, around 135,000 new registrations were made. The estimated number of unreported cases is at least 30%. The plan sets out a number of goals: to reduce the transmission of mothers to babies to below 4% of new infections, and to inform more than 95% of all students about the diagnosis of HIV and its transmission routes. 

According to a blog, between July and September 2018 about 80% of all deaths from infectious diseases were due to HIV. The Chinese Association of Sexually Transmitted Diseases and AIDS Prevention and Control (中国性病艾滋病防治协会) reported that since April 2018, 10 universities have installed a total of 22 HIV diagnostic machines on campus. Only a coded urine sample has to be placed in the vending machine. The urine donor then receives the results online and anonymously within the next 3 to 5 working days. In one month 59 kits were sold and 37 samples returned, two of which were HIV positive.

Chloroplast DNA barcoding tell Chinese drug from adulterants

Researchers from the Chinese Academy of Sciences have successfully employed genetic barcoding to tell original drugs of Traditional Chinese Medicine (TCM) from adulterants. Extracts of Drynaria roosii Nakaike are traditionally used in China for the treatment of bone diseases, but extracts from some closely related plants are without effect. Comparing chloroplast genome sequences of all these plants, 12 protein-coding genes and eight intergenic sequences with high divergence in chloroplast genomes were identified and led to the development of four primer pairs which allow to distinguis D. roosii from adulterants and guarantee for the quality, safety, and effectiveness of the drug.

Ministry of Agriculture issues stricter rules for veterinary drug residues in food

The new standards stipulate 2191 residual values ​​and requirements for use of 267 veterinary drugs for livestock and poultry, marine and bee products. It covers almost all veterinary drugs commonly used in China, the main animals used for food production and will come into effect on April 1, 2020. The new standards adopt CAC standards (International Food Standards Committee) to an extent of about 90%. Important technical values ​​such as allowable intake, residual standard values and usage requirements were completely revised. For more than 10 veterinary drugs with food safety risks such as ofloxacin, significant changes were issued.

Smart trash collecting machine in Nanjing offers “cash for trash”

In order to encourage residents to separate trash, Nanjing City has introduced “trash banks” that integrate functions such as face recognition, remote monitoring, and trash disposal. The residents first perform face recognition, and then sort out the trash. The system returns points to the user’s account based on the number of recyclables contained in the garbage. Eventually points can be turned into cash.
