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.

Tsinghua University develops novel chip architecture for general artificial intelligence

The chip is based on a hybrid architecture combining a many-core architecture, reconfigurable building blocks and a streamlined dataflow with hybrid coding schemes. It can not only accommodate computer-science-based machine-learning algorithms, but also easily implement brain-inspired circuits and several coding schemes. Using just one chip, the team around Luping SHI demonstrated the simultaneous processing of versatile algorithms and models in an unmanned bicycle system, realizing real-time object detection, tracking, voice control, obstacle avoidance and balance control.

CAS Dalian Institute of Chemical Physics develops rechargeable aqueous planar Zn//MnO2 micro-batteries fabricated by screen printing technology

The group of WU Zhongshuai from DICP has used a thixotropic ink based on manganese dioxide, zinc powder and graphene as active materials, to produce the positive, negative electrodes and the current collector of Zn//MnO2 batteries, respectively. In a multi-step screen printing process, a simple and low-cost preparation of planar Zn//MnO2 micro-batteries was achieved. The Zn//MnO2 batteries showed exceptional durability, with a capacity of 83.9% for 1300 cycles at current density of 5 C, good mechanical flexibility and uniform performance.

Alipay starts payment based on face recognition, beauty filters for ladies

An improved facial recognition point-of-sales system of Alipay, named Dragonfly, has been upgraded by “beauty filters”, upon complaint by female consumers that facial recognition machines captured unflattering images. According to the company, this new feature has attracted more female consumers to pay with this system.

Alipays new system is now installed in over 40 Xinhua Bookstores in Zhejiang Province and will be gradually expanded to over 14,000 outlets.

Alipay offers software to help sort garbage

The Chinese government has set a goal of 35 percent for household garbage recycling by 2020, and Shanghai has put into effect compulsory regulations from July 1, 2019. 45 other cities are about to follow soon.

In response to this move, Alipay offers the beta phase of a “Garbage classification guide” that has indexed over 4,000 different types of waste such as  shrimp shells, facial masks, sunflower seed shells, medical cotton swabs etc. The customer takes a photo of a particular garbage or describes the garbage by voice; the software then applies either voice recognition or augmented reality (AR) scanning and image recognition, and provides suggestions by voice or text.

Reportedly, over 3 million people have already tried out the new function by scanning waste items with their smartphones, which answers within seconds in which type of  litter bin a waste item belongs.

CAS Fujian Institute improves low-cost rare earth extraction process

The group of SUN Xiaoqi from CAS Fujian Institute of Research on the Structure of Matter has developed a new method for the isolation of rare earth metals from softening ammonia sulfate wastewater produced during bastnasite ammonia sulfate roasting. Based on alkyl phenoxy carboxylic acid derivatives [4,4′-isopropylidenebis (phenoxyacetate)]as a cation exchanger, Ca2+and Mg2+are precipitated from the wastewater within 10 min, forming particles which can be easily separated. The ion exchanger was repeatedly used 5 times with little loss, contributing to a process with low cost and little pollution.
