Penn team proposes liquid-organic hydrogen carriers as endothermic fuels for hypersonic aircraft

Green Car Congress

A team at the University of Pennsylvania is proposing the use of a liquid-organic hydrogen carrier (LOHC)—specifically, 1,2,3,4 -tetrahydroquinoline (THQ)—for use as an endothermic fuel for thermal protection of hypersonic aircraft engines. 1 were obtained, with conversions greater than 80% at 600 °C.

New energy-efficient process for direct conversion of biomass without pretreatment to liquid hydrocarbon fuels

Green Car Congress

A team from The University of Manchester and East China University has developed a process for the direct hydrodeoxygenation of raw woods into liquid alkanes with mass yields up to 28.1 wt% wt% over a multifunctional Pt/NbOPO 4 catalyst in cyclohexane. The reactions were conducted at 190 °C and 5 MPa H 2 for 20 h.

New "E-nose" Samples Odors 60 Times Per Second

Cars That Think

When odorants are carried away by turbulent airflow, they get chopped into smaller packets,” says Michael Schmuker , a professor at the University of Hertfordshire in the United Kingdom. These curves capture the sensor’s conversion of a physical interaction—like an odor molecule binding to its surface—into an electrical signal.
