adminAerospace 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.
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.
adminDrivers 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.
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.
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.
adminPlastic 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.
adminIn the quest for renewable fuels, scientists are taking lessons from a humble bacterium that fills our oceans and covers moist surfaces the world over. Cyanothece 51142, a type of bacteria also called blue-green algae, produces hydrogen in robust fashion, and scientists have found that it taps into an unexpected source of energy to do so.
