Audi has introduced the natural-gas-fueled A4 Avant g-tron; dealers in Europe will begin taking orders for the midsize model starting in early summer 2017. Additionally, Audi is now offering e-gas to power the A3 Sportback g-tron as standard; customers will pay only the regular natural gas price. lb per 62.1 lb per 62.1

Furfural is first hydrogenated into THFA, which is then dehydrated in the gas phase to produce dihydropyran (DHP) with 87% yield. Huber’s approach uses the oxygen already inherent in the biomass to produce high value oxygenated commodity chemicals that can be used to make performance polymer materials such as polyurethanes and polyesters.

In a new departure, the A5 Sportback is also available as a bivalent g-tron, which customers can run on either Audi e-gas ( earlier post ), natural gas or gasoline. The tanks for the gas fuel in the A5 Sportback g-tron are located beneath the rearward structure. lb) of gas per 100 kilometers (62.1 Audi e-gas.

A team at University College London (UCL) has used a lung-inspired approach to designing flow fields to improve significantly the performance of polymer electrolyte fuel cells. The final generation of H-shaped branches of the N = 3 and N = 4 flow-fields were left open to create additional contact area between the gas channel and the GDL.

The process could significantly lower the cost of producing the one-dimensional (1D) nanostructures, enabling a broad range of uses in lightweight structural composites, advanced sensors, electronic devices—and thermally-stable and strong battery membranes able to withstand temperatures of more than 1,000 ˚C. —Gleb Yushin.
