The prospects for hydrogen as an energy carrier: an overview of hydrogen energy and hydrogen energy systems [PDF]
Energy, Ecology and Environment, 2016 Hydrogen is expected to play a key role as an energy carrier in future energy systems of the world. As fossil-fuel supplies become scarcer and environmental concerns increase, hydrogen is likely to become an increasingly important chemical energy carrier and eventually may become the principal chemical energy carrier.

Modelling ultrasound waves bubble formation in ethanol/ethyl acetate azeotrope mixture [PDF]
E3S Web of Conferences, 2019 The separation of an azeotropic mixture such as ethanol/ethyl acetate in distillation process can be enhanced by ultrasound wave. The application of ultrasound wave creates bubble cavitation in the mixture and shifts the vapour-liquid equilibrium ...
