4C nanodiamond

World’s hardest material, diamond, is flexible

Diamond, the world’s hardest material, turns out to be flexible. Scientists from NTU Singapore, MIT, City University of Hong Kong and South Korea made the surprising discovery and found that diamonds can be stretched by up to 9% without breaking. This could lead to new applications in computing, healthcare and materials engineering.

No looking back for chemical manufacturing

In synthetic chemistry, a chemical reaction called nucleophilic substitution occurs when a nucleophile (electron-rich chemical species) replaces a leaving group (electron-poor fragment of an organic molecule). Typically, the nucleophile attacks...
