New heterogeneous acid catalyst shows high activity in release of hydrogen from sodium borohydride; lowest activation energy yet reported

Green Car Congress

'A team from the Indian Institute of Technology Bombay has devised a heterogeneous acid catalyst, silica sulfuric acid, that shows high activity towards releasing hydrogen from sodium borohydride (NaBH 4 ), with a hydrolysis rate of 5.5 L min ?1 g ?1. Further, the activation energy of the NaBH 4 hydrolysis reaction in the presence of the catalyst was calculated to be the lowest (17 kJ mol ?

A*STAR researchers develop predictive model for mass-transit train overloading

Green Car Congress

'Researchers at A*STAR in Singapore have developed a model that uses smartcard ticket data to provide valuable predictive data on potential train overloading for Singapore’s public transport system. This will enable system planners to address critical bottlenecks as the system stretches to accommodate an expanding population. More than one million commuters—roughly 20% of Singapore’s population—use the mass rapid transit (MRT) system every day.
