Boron nitride, tougher than it looks
During World War I, a British aeronautical engineer named A.A. Griffith noticed something odd about glass. He found that the atomic bonds in glass needed 10,000 megapascals of stress to break apart – but a macroscopic mass of glass could … Continue reading

The ‘could’ve, should’ve, would’ve’ of R&D
ISRO’s Moon rover, which will move around the lunar surface come September (if all goes well), will live and and die in a span of 14 days because that’s how long the lithium-ion cells it’s equipped with can survive the … Continue reading

Graphene the Ubiquitous
Every once in a while, a (revolutionary-in-hindsight) scientific discovery is made that’s at first treated as an anomaly, and then verified. Once established as a credible find, it goes through a period where it is subject to great curiosity and … Continue reading
