Giuseppe  Cotellessa / Reported by Dr.  Joseph Cotellessa Problems with lithium ion cell fires grounded Boeing’s 787 fleet last year. A relatively simple fix could be the key to developing solid-state lithium-ion batteries, without the flammability problem of conventional Li-ion cells The propensity for lithium-ion batteries to catch fire has had major connotations in recent years, temporarily grounding Boeing’s fleet of 787 Dreamliners in 2015 and potentially spoiling Samsung’s reputation for making high-quality consumer electronics after problems with fires in its Galaxy Note tablets. The problem is caused by the liquid electrolyte used in most cells, which is flammable, especially at high temperatures. One way to get around this is to use a solid-state battery; but attempts to de

Segnalato dal Dott.  Giuseppe Cotellessa  / Reported by Dr. Joseph  Cotellessa (Credit: Ajayan Group/Rice University) Scientists at Rice University have used graphene quantum dots combined with nitrogen atoms to transform CO2 into liquid fuel. Described in the journal   Nature Communications , the nitrogen-doped graphene quantum dots (NGQDs) act as an electrocatalyst, converting the greenhouse gas into small batches of ethylene and ethanol. Although the researchers say they don’t fully understand the mechanism at work, the NGQDs are as efficient a catalyst as copper, which is also being tested to turn CO2 into complex hydrocarbons. Furthermore, the quantum dots also retain their catalytic activity for a long time. “It is surprising because people have tried all different kinds of catalysts, and there are only a few real choices such as copper,” said Rice
