Photosynthetic proteins can convert light energy into other forms of energy. Researchers want to make this technology usable for the industrial production of fuels, for example. A research team from the Ruhr-Universität Bochum (RUB), together with colleagues from Lisbon, has produced a ...
Formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial
New Curtin University-led research has shown the formation of bubbles on electrodes, usually thought to be a hindrance, can be beneficial, with deliberately added bubbles, or oil droplets, able to accelerate processes such as the removal of pollutants such as hydrocarbons from contaminated water ...
How the stability of photoelectrodes and catalysts can be compared and enhanced in the future
As part of an international collaboration, a team at the HZB has examined the corrosion processes of high-quality BiVO4 photoelectrodes using different state-of-the-art characterisation methods. The result is the first operando stability study of high-purity BiVO4 photoanodes during the ...
It’s all about good cooperation
By splitting water electrochemically, green hydrogen can be produced, which can be used as fuel, energy storage and for chemical reactions. This way, we can decrease our dependence on fossil resources and reduce greenhouse gas emissions. However, the electrolysis of water consumes a lot of ...
An electric vehicle with such a battery could travel 600 miles on a single charge
Electric vehicles are gaining in popularity, but their long charging time is a significant detraction for potential customers. While a typical SUV with a combustion engine could travel 300 miles with a five-minute refuel, a state-of-the-art electric vehicle takes about one hour to store enough ...
Biobased process for ammonia production
Bacterial enzymes are often powerful but also very sensitive catalysts. To call up their performance, they therefore need a special environment. Researchers at Ruhr-Universität Bochum (RUB) have developed new techniques for efficiently coupling bacterial enzymes to electrodes. Together with a ...
A mixture of liquid and solid state batteries
Researchers in the Cockrell School of Engineering at The University of Texas at Austin have built a new type of battery that combines the many benefits of existing options while eliminating their key shortcomings and saving energy. Most batteries are composed of either solid-state electrodes, ...
Recycling of rechargeable hydride batteries may be easier with a new method
A new method for recycling old batteries can provide better performing and cheaper rechargeable hydride batteries (NiMH) as shown in a new study by researchers at Stockholm University. "The new method allows the upcycled material to be used directly in new battery production," says Dag Noréus, ...
Another step forward for renewable energies: The production of green hydrogen could be even more efficient in the future
By applying an unusual process step, chemists at Martin Luther University Halle-Wittenberg (MLU) have found a way to treat inexpensive electrode materials and considerably improve their properties during electrolysis. Hydrogen is thought to be the solution to the storage problem of renewable ...
Dr. Yoon Hana at Energy Conversion & Storage Materials Laboratory of Korea Institute of Energy Research (KIER, President Kim Jong-nam), Professor Kim Young-Jin (Dept. of Mechanical Engineering, Korea Advanced Institute of Science and Technology) and Professor Kim Seungchul (Dept. of Optics and ...
