Mombasa-Nairobi standard gauge railway (SGR) revisited

The SGR passenger train covers a total distance of 472 kilometres and is the first standard gauge railway completed in Africa. It was designed using Chinese technology, standard, equipment and funding. SGR is run by AfriStar, with 2,248, or nearly 80%, of its employees from Kenya. Four passenger trains run on a daily basis. Since its opening in May 2017, the SGR has carried 4 million passengers, with an average attendance rate of 95%. In addition, 16 freight trains run daily on average, and nearly 6 million tons of cargo was transported in 2019, up 70% compared with 2018. The SGR passes through Kenya’s largest conservation park, Tsavo National Park.

Photosynthetic capacity at night makes “mile-a-minute” weed a particularily harmful invasive plant

Mikania micrantha, dubbed “mile-a-minute” weed, is one of the top 100 worst invasive species and one of the most harmful invasive plants, also in south China. WAN Fanghao, Chinese Academy of Agricultural Sciences, and colleagues have prepared a 1.79 Gb reference chromosome map and have shown that half of the genome is composed of long terminal repeat retrotransposons, including a whole genome duplication event. Mikania micrantha achieves higher photosynthetic capacity by CO2 absorption at night to supplement its carbon fixation during the day, as well as enhanced stem photosynthesis efficiency. Furthermore, the metabolites of the plant can increase the availability of nitrogen by enriching microbes that participate in nitrogen cycling pathways.

CAS Shenyang Institute of Automation develops novel image forgery detection technology

The new technology is based on an improved method to detect motion blur. A parameterized motion blur kernel is mapped into the 3D pose space of the camera to obtain a 3D pose set, and the intersection of the 3D pose sets (shared pose set) corresponding to multiple image patches is obtained. Compared with state-of-the-art methods, the detection accuracy of the proposed method is claimed to be improved by more than 20%.

“Agriculture 4.0” supported by drones and AI in Guizhou Province

On an area of ​​5,000 mu (approximately 333.3 hectares) with an average altitude of more than 2,200 meters at Wei Ning Yi Hui Miao Autonomous County, engineers seek lead technologies for vegetable production such as Chinese or white cabbage and radish. 5G-supported drones with multispectral equipment monitor crop growth, soil moisture and weather conditions and make decisions using an AI judgment system. Remote operation maintenance and quality tracing will be installed in Guiyang city. If the “smart farm” trial is successful, 400,000-mu (approximately 26,700 hectares) vegetable bases will also be built in all prefectures.

Graphene nanostructures provide path to quantum materials

GAO Hongjun and colleagues from CAS Institute of Physics have achieved atomically precise folding of graphene nanostructures through STM tip-induced manipulation technology. They were able to fold graphene nanoislands in an arbitrarily chosen direction, constructed bilayer graphene stacks withs a tunable twist angle and a tubular edge connection between the layers, and created intramolecular junctions of bicrystal graphene nanoislands. Atomically precise “origami” can be used for the construction of quantum materials and quantum devices.

Solar energy to methanol pilot plant opened in Lanzhou

The project initiated by LI Can of CAS Dalian Institute of Chemical Physics combines hydrogen production by electrocatalytic water splitting with highly selective, carbon dioxide hydrogenation to methanol. Energy consumption is reduced to 4.0-4.2 kWh / m3 hydrogen. Carbon dioxide hydrogenation to methanol uses a bimetal oxide catalyst (ZnO-ZrO2). Methanol selectivity is greater than 90%, and degradation of the catalyst after 3000 hours of operation is less than 2%. A1,000-ton scale demonstration project was commissioned in the Green Chemical Park in Lanzhou New District.
