PLA porous microneedles: rapid detection of covid-19 antibody without blood samples
Japanese researchers have developed a new antibody based method for rapid and reliable detection of novel coronavirus without the need for blood samples. The research results were recently published in the journal Science report. The ineffective identification of people infected with covid-19 has seriously limited the global response to COVID-19, which is exacerbated by the high asymptomatic infection rate (16% – 38%). So far, the main test method is to collect samples by wiping the nose and throat. However, the application of this method is limited by its long detection time (4-6 hours), high cost and the requirements for professional equipment and medical personnel, especially in countries with limited resources. After proving that interstitial fluid may be suitable for antibody... -

EU: mandatory use of recycled materials, recycled PP soaring!
According to icis It is observed that market participants often lack sufficient collection and sorting capacity to meet their ambitious sustainable development goals, which is particularly prominent in the packaging industry, which is also the biggest bottleneck faced by polymer recycling. At present, the sources of raw materials and waste packages of three major recycled polymers, recycled PET (RPET), recycled polyethylene (R-PE) and recycled polypropylene (r-pp), are limited to a certain extent. In addition to energy and transportation costs, the shortage and high price of waste packages have driven the value of renewable polyolefins to a record high in Europe, resulting in an increasingly serious disconnect between the prices of new polyolefin materials and renewable polyolefins, whi... -
Polylactic acid has achieved remarkable results in desertification control!
In chaogewenduer Town, wulatehou banner, Bayannaoer City, Inner Mongolia, aiming at the problems of serious wind erosion of the exposed wound surface of the degraded grassland, barren soil and slow plant recovery, researchers have developed a rapid recovery technology of degraded vegetation induced by microbial organic mixture. This technology uses nitrogen fixing bacteria, cellulose decomposing microorganisms and straw fermentation to produce organic mixture, Spraying the mixture in the vegetation restoration area to induce the formation of soil crust can make the sand fixing plant species of the exposed wound of the degraded grassland settle down, so as to realize the rapid repair of the degraded ecosystem. This new technology is derived from the national key research and development ... -

Chemdo group dined together cheerfully!
Last night, all the staff of Chemdo dined together outside. During the activity, we played a guessing card game called “More than I can say”.

The rules of the game are not complicated, but you will find the New World once you get to the bottom of the game, which is a great test of the players’ wisdom and quick reactions. We need to rack our brains to guide others to make instructions as naturally as possible, and always pay attention to whether others’ traps and spearheads are pointing at ourselves. We should try to roughly guess the card content on our head in the process of con... -
