Xinjiang has a 600 km long rare metal metallogenic belt

Karakorum, Xinjiang Province (Wikipedia)

The Ministry of Science and Technology recently confirmed that the rare metal resources of Karakorum in Xinjiang are comparable to the rare metal metallogenic areas in western Sichuan. The exploration and evaluation was done both by remote sensing in the alpine region and rapid verification on ground, and a geologic and mineral resources database was established.

The southern three states of Xinjiang are among the most important metallogenic belts in China, with huge resource potential and superior metallogenic conditions. However, due to limited basic geological work and a low degree of mineral exploration, the development of a mining economy in southern Xinjiang was hitherto limited.

The People’s Government of the Autonomous Region and the Ministry of Science and Technology now agreed to stimulate exploration together with 18 research institutes, universities, geological exploration units and mining enterprises across the country. Three large-scale ore-concentrating areas and 37 prospecting targets were identified. Targeted resources include rare metals, lead and zinc, iron, manganese and gold.

BGI publishs genome study based on over 140,000 Chinese

About 78 percent of all studies about the relationship of gene and diseases are based on European individuals. Beijing Genomics Institute (BGI), one of the most prolific global DNA sequencing institutions located in Shenzhen, has now published a study on the genomes of 141,431 Chinese women generated for non-invasive prenatal testing (NIPT), mostly Han Chinese from China’s East coast. Features include that six genes display significant differences of Chinese people across latitudes, and people from the southern part of China have developed stronger immunity against malaria than those in the north, but a gene related to fatty acid metabolism has a much higher frequency in most of the northern provinces. In addition, people in Gansu and Qinghai provinces, a key area of the Silk Road, share more similar genes with Europeans.

CAS Tianjin Institute of Industrial Biotechnology uses in-vitro multi-enzyme cascade to achieve complete conversion of cellulose

Aresearch team led by researcher YU Wei, a researcher at the In Vitro Synthetic Biology Center of CAS Tianjin Institute of Industrial Biotechnology, designed an enzymatic phosphate pathway for the stoichiometric conversion of cellulosic biomass using an in vitro multi-enzyme system. This pathway utilizes three cascades of phosphorylase (cellodextrin phosphorylase (CDP), cellobiose phosphorylase (CBP), and polyphosphate-dependent glucokinase (PGGK). )) The fiber polysaccharide is converted into high-energy phosphorylated sugar (glucose 1-phosphate and glucose 6-phosphate). Subsequent enzymes can be used to produce hydrogen, bioelectricity, or high-value chemicals. The research team used inositol as the final product and reached a yield of 98%, close to the stoichiometric substrate conversion. In addition, the in vitro multi-enzyme system also produced inositol from a corn stover hydrolysate as substrate.

CAS team finds bamboo shoot fibers to improve insulin sensitivity in mice on a high-fat diet

The group of ZHANG Ping at CAS Xishuangbanna Tropical Botanical Garden has studied body weight gain in mice fed with isoenergenic high-fat diets and containing bamboo shoot fiber (BSF) from eitherD. hamiltonii or D. latiforus. They found that bamboo shoot fibers suppressed high-fat-diet-induced body weight gain in mice and improved glycemic control and insulin sensitivity. At the molecular level, BSF enhanced insulin signaling measured by phosphorylated Akt, induced elevated expression of PGC-1α and more phosphorylation of AMP K and p38.

New sensing material detects mercury pollution in real time

A team around YANG Jintao from Zhejiang University of Technology and colleagues from the AS Ningbo Institute of Materials Technology and Engineering have developed a hydrophilic fluorescent hydrogel‐coated flexible paper/textile film chemosensor which displays a “green‐to‐blue” emission color change upon specific chemical reaction between Hg2+ and the grafted thiourea moieties. The porous structures allow for fast capillary‐force‐driven mercury(II) diffusion into the hydrophilic hydrogel matrix, thus enabling visual detection of nearly nM‐level Hg2+. On this basis, fluorescent hydrogel‐coated wearable sensing gloves were fabricated, which significantly facilitated visual detection of toxic Hg2+‐polluted samples.

CAS DICP achieves 80 % selectivity for coupling of methanol and CO to produce aromatic hydrocarbons

LIU Zhongmin and ZHU Wenliang, at the CAS Dalian Institute of Chemical Physics have developed a metal-modified H-ZSM-5 zeolite which showed excellent selectivity for preparing aromatics by coupling methanol and carbon monoxide. China has abundant coal reserves and is a major global producer of methanol. The aromatization mechanism proceeds via a carbonyl intermediate, which reacts with olefin to form a cyclopentenone intermediate, followed by dehydration to an aromatic hydrocarbon.

China opens “virtual satellite ground stations” in 10 countries along the “belt and road”

The Institute of Aerospace Information Research has opened “virtual ground stations” in Mongolia, Kenya, Sri Lanka, Cambodia, Kyrgyzstan, Kazakhstan, Nepal, Thailand, Venezuela and Belgium. In these 10 countries, the institute’s self-developed virtual ground stations receive near-real time data from China’s remote satellite ground stations which support satellites such as the HJ-1A, HJ-1B, Landsat-8 and Proba-V which have played an important role in ecological environment monitoring and disaster alleviation. The data can be received without actually installing a satellite reception antenna. China’s remote sensing satellite ground stations cover 70% of all land in Asia, and China’s data transmission network and big data real-time processing technology is advanced.

Team at China University of Science and Technology prepares high performance conductive hydrogel fiber inspired by spider silk

The group of MA Mingming research group of the University of Science and Technology of China have coated sodium polyacrylate (PAAS) with a polymetacrylate (PMA) waterproof layer forming a PMA-PAAS with a core-shell hydrogel fiber (MAPAH fiber). In the MAPAH fiber, the PAAS crystalline region and the amorphous region coexist and can undergo rapid reversible interconversion, so that the MAPAH fiber exhibits excellent mechanical properties, electrical conductivity, and freeze resistance. MAPAH fibers have high tensile strength (5.6 MPa) and large elongation at break (1200%) and can be quickly recovered after extensive stretching. The PAAS hydrogel acts as a conductive core (conductivity 2 S m-1), and the PMA layer acts as a waterproof and insulating coating, making the MAPAH fiber an elastic wire with high stretchability. MAPAH fiber also maintains the arrangement and orientation of the polymer chains by gel spinning. As a high performance and low cost elastic stretchable conductive hydrogel fiber, MAPAH fibers will be used to develop stretchable electronic devices in textile materials.

CAS DICP improves synthesis of aromatic hydrocarbons from CO2

A team around CAS Academician LIU Zhongmin at CAS Dalian Institute of Chemical Physics has developed a ZnAlOx & H-ZSM-5 catalyst, a nano-spinel structured ZnAlOx oxide mixed with nano-H-ZSM-5a zeolite of a high silicon-to-aluminum ratio. This catalyst provided 73.9 % selectivity for aromatics formation from carbon dioxide hydrogenation, with only 0.4 % selectivity from methane. Mechanism studies showed that carbon dioxide is hydrogenated on ZnAlOx to form dimethyl ether and methanol, which diffuse into the pores of the molecular sieve to form olefins, which in turn form aromatic hydrocarbons. Compared to carbon monoxide hydrogenation, carbon dioxide hydrogenation leads to more formate species on the surface of ZnAlOx, leaving less metal active sites. These factors all contribute to the formation of aromatics with high unsaturation.
