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 […]

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. […]

Six Chinese military trade companies at largest African Air Aeronatics and Defense Trade Show

At the 10th African Air Aeronautics and Defense Trade Show in Pretoria, among over 300 companies from 37 countries worldwide, there also was a China Defence mission with six military trade companies. Their emergence was widely noticed by the government, military experts and exhibitors. The mission showed missile weapons systems, naval vessels, military aircrafts, unmanned […]

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 […]

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 […]

CAS Institute of Chemistry achieves electrocooling using new organic thermoelectric materials

Electrocooling can be achieved by the Peltier effect with appropriate materials.Using poly(Ni-ett) thin-film devices, a temperature difference of > 40 degrees Celsius was achieved, allowing for electrocooling of organic thermoelectric devices. It is predicted that ultra-thin devices of this type of material can achieve large temperature difference electrocooling with a heat flux density exceeding 500 […]

China boosts science literacy by science museums

The China Association for S&T (CAST) held a World Conference on Science Literacy in Beijing which was attended by over 1,000 scientists and representatives from 38 countries and regions, as well as 23 international scientific organizations and 58 national scientific institutes. The final declarationcalled for working together to close the gap in scientific literacy between […]

CAS Xishuangbanna Tropical Gardens and others develop “AI Botanical Garden Plan”

The plan involves several botanical gardens throughout China and is first implemented as a test point in Shanghai Botanical Garden, which offers a test base during the 2018 World Artificial Intelligence Competition. Visitors can obtain knowledge about plants by using the image recognition functions of an AI-based software system. JST Japan China news, September 19, […]

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 […]

China plans for juvenile health improvement using big data

Beijing recently held a symposium on child nutrition and health, and experts agreed that nutritional deficiencies still exist, and the obesity rate continues to rise. Nationwide data are now covered in a public database which include information on average height, weight, blood lipids and nutritional intake data based on daily menus. The constitution of children […]
