Benefits of adding a second, smaller rotor to wind turbines

Aerospace engineers are developing dual-rotor technology to improve the energy harvest of wind turbines. The idea to look for better performance by adding a second rotor to wind turbines came from a previous study. The researchers used wind tunnel tests to see how hills, valleys and the placement of turbines affected the productivity of onshore wind farms.

Neutrons offer guide to getting more out of solid-state lithium-ion batteries

A new study has revealed promising results that could drastically boost the performance of solid-state electrolytes, and could potentially lead to a safer, even more efficient battery. Researchers used neutron diffraction (the VULCAN instrument, SNS beam line 7) to conduct an in-depth study probing the entire structure evolution of doped garnet-type electrolytes during the synthesis process to unravel the mechanism that boosts the lithium-ionic conductivity.

Speeding up the hydrogen highway

Drivers are seeing more hydrogen fuel cell electric vehicles on the road, but refueling stations for those vehicles are still few and far between. This is about to change. One reason is the Hydrogen Station Equipment Performance device, or HyStEP, which will greatly accelerate station commissioning.

U.S. demonstrates production of fuel for missions to the solar system and beyond

The first U.S. production in nearly 30 years of a specialized fuel to power future deep space missions has been completed by researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) in Tennessee.

Researchers use neutrons to gain insight into battery inefficiency

Lithium ions are depleted as a battery charges and are also lost to the formation of a thin coating on a battery’s anode. Researchers used powerful neutron science facilities to try to understand the dynamics behind this phenomenon.

X-rays reveal details of plastic solar cell production

Plastic solar cells are light, easy to install, and readily produced using a printer. Nevertheless, the processes that take place on the molecular scale during the production of organic solar cells are not yet entirely clear. Researchers have now managed to observe these processes in real time. Their findings could help to improve the efficiency of organic solar cells.
