Window to China
The observatory operates a ground-based high-resolution Fourier transform spectrometer and measures the amount of carbon dioxide, methane, carbon monoxide, nitrous oxide and other trace gases in the Earth’s atmosphere. The station is part of an international network which validates satellite data, such as those from greenhouse gases observing satellite (GOSAT, Japan), Orbiting Carbon Observatory 2 […]
The group of Fang XU has used a cellulose and pectinase cocktail to produce fermentable sugars from hydrothermally treated potato pulp, an important crop in China. They produced D-gluconic acid in high yields from this carbon source using Gluconobacter oxidans DSM 2003. Transformation of glucose to gluconic acid was 94,4 %, and productivity was about […]
The groups of JIANG Yijun and WU Pingwei have crosslinked paper and regenerated cellulose to a composite (RCP) which showed unexpected mechanical strength at dry (tensile strength: 76 MPa, toughness at break: 7 MJ/m-1) and wet conditions (tensile strength: 13 MPa, toughness at break: 0.75 MJ/m-1), much higher than original paper. The composite had good […]
The services will include pre-clinical disease prevention, registration, mobile payment, report view, electronic prescription, drug sales distribution, follow-ups, rehabilitation guidance, etc. The concept is to help physical hospital out of geographical distance restrictions, greatly expand their service radius, and educate patients. Jingdong Pharmaceutical has already established self-employed retail pharmacies where a patient can shop from […]
A joint study of 2 institutes of the Chinese Academy of Sciences, the People’s Liberation Army and a US group based on data on ocean heat content collected since 1970 show that oceans have warmed consistently. Below 100-m depth in the Atlantic and Southern Ocean, and between 100-300m depth in the Pacific and Indian Ocean, […]
The association has just released A2β-casein gene screening technology which allows to select for this trait in cow breeding. A2β-casein is closest o breast milk. It is easy to be digested and absorbed by the body, and has a better somatosensory quality. Modern dairy cows produce mostly A1β casein, which is of less quality; A2 […]
The group of YANG Sheng at CAS SIBS Key Laboratory of Synthetic Biology developed a a Francisella novicida CRISPR-Cpf1-based genome-editing method for C. glutamicum. Using CRISPR-Cpf1, combined with single-stranded DNA (ssDNA) recombineering, small changes could be precisely introduced into the bacterial genome at efficiencies of 86–100%. Using this method, each round of iterative metabolic engineering was achieved in as […]
The team from CAS and Peking University observed that oxime-carbamate structures were reversible at about 100 °C through oxime-enabled transcarbamoylation via a thermally dissociative mechanism. Using this observation, they produced polyurethane-like poly(oxime-urethanes) (POUs) by uncatalyzed polyaddition of multifunctional oximes and hexamethylene diisocyanate (HDI) at ambient temperature. Kinetics studies showed almost complete polymerization (∼99% conversion) in […]
“Janus particles” are defined by controllable topological and chemical anisotropy. In their study, Shutao WANG and colleagues chose a typical oil-in-water emulsion system, styrene (St) and divinyl benzene (DVB) in water emulsion, into which hydrophilic monomer (such as, acrylic acid (AA) or acrylamide (AM) et al. ) were introduced as anchoring molecules. The polymerization was […]
According to LI Yu, Chinese Academy of Engineering, China in 2015 produced over 34 million tons of edible fungi in about 600 factories, with a value of some 3 billion USD. Top varieties are Flammulina velutipes (Enokitake), Pleurotus eryngii (king trumpet mushroom) and Hypsizygus tessellatus (crab mushroom). While China is among the world’s earliest countries […]
