Hydrogenated polycyclic aromatic hydrocarbons (PAHs) have been proposed to contribute to the formation of interstellar H2 by acting as a surface catalyst for the adsorption of hydrogen atoms and desorption of H2 molecules. In the present study, imaging photoelectron photoion coincidence (iPEPICO) ...

As a result storms that form over the Pacific deliver heavier water to California than to Utah. Similar patterns exist throughout the U.S. By measuring the proportion of heavier hydrogen and oxygen isotopes along a strand of hair scientists can establish a geographic timeline. Each inch of ...
CGTN reporter Li Jianhua sits down with Rodrigo Zeidan, Associate Professor from New York University in Shanghai, and Jenny Zhang, General Manager of Bellagio by MGM Shanghai. To know more about how Pudong's development has been contributing to the growth of Shanghai's h...
This is so much safer than using chemicals, and it works better than what I had been using. Plus, it’s natural!!” I’d love to hear from someone who has used lemon essential oil toremove permanent marker stains, so if that’s you, please let me know in the comments!
While carbon-14 is commonly used for dating, the principle applies to other isotopes as well, such as potassium-40 and uranium-235, but the accuracy of radioisotope dating may be compromised for anything that dies after the 1940s due to changes in carbon ratios from nuclear activities and fos...
Functional groups can show up on all sorts of carbon chains. But if the focus of our discussion is a functional group, we don’t want to get distracted by all of the carbons, hydrogens, or anything else in the parent chain. Instead, wereplacethe entire parent chain with the letter R ...

when you're trying to keep names of reactions and structures straight in your head. Memorizing won't guarantee you a great grade on a test, but it's an important tool to use. There's more than one way to do it. Here are some of the best (and worst) ways to memorize chemistry. ...
China plays a leading role in driving the world’s low-carbon journey forward, from building a new generation of energy infrastructure to having the largest green hydrogen project on the planet. How can exchanges support this global green agenda? Read HKEX CEO Bonnie Y Chan’s views in a pie...
