My Dumb Diaary

Do you believe in Ghosts or such Supernatural beings? This question has been there since time immemorial. A large section of people around the world consider these as just made up phony theories and superstitious beliefs, used for telling interesting stories or scaring kids. But is it really so? There has been a long history of such scary stories. Many movies have now been filmed based on said true events, such as Annabelle, Conjuring and such other. But considering that it just might be a publicity stunt from the film-makers, we can deny it. But what if something of the sort happens with you in reality? Would you believe it then?

LONDON: Scientists have been able to track the entire process of what happens inside lithium-ion batteries that leads to their overheating and exploding. "Understanding how Li-ion batteries fail and potentially cause a dangerous chain reaction of events is important for improving their design to making them safer to use and transport," said the scientists. "We combined high energy synchrotron X-rays and thermal imaging to map changes to the internal structure and external temperature of two types of Li-ion batteries as we exposed them to extreme levels of heat," said first author Donal Finegan from University College London (UCL). The team looked at the effects of gas pockets forming, venting and increasing temperatures on the layers inside two distinct commercial Li-ion batteries as they exposed the battery shells to temperatures in excess of 250 degrees Celsius. The battery with an internal support remained largely intact up until the initiation of thermal runa...
