A joint research team led by Profs. LIN Yangting and LIN Honglei from the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IGGCAS) observed water signals in reflectance spectral data from the lunar surface acquired by the Chang'E-5 lander

Ethylene is one of the most important building blocks in chemical synthesis. Traditional thermocatalytic hydrogenation of acetylene to ethylene (HAE

Helium is the epitome of quantum mechanics because of its small mass and inertness to react. It does not freeze even till absolute zero - unless higher...

Two-Luminogen Hydrogel Chemosensor Detects Seafood Freshness by Changing Color Written by AZoMMay 7 2021 A team of researchers from Germany and China has developed a novel artificial color-changing material that imitates the skin of a chameleon, through luminogens (molecules that cause crystals to glow) arranged into different core and shell layers of hydrogels rather than a single uniform matrix. This image shows the color change of the “chameleon skin” hydrogel-based chemosensor in response to biogenic volatile amine vapors, which are a well-known indicator of fish and shrimp spoilage. ...
