Coating Shewanella bacteria with silver nanoparticles greatly boosts the performance of biofilm-based microbial fuel cells, researchers report. It achieves this effect by improving the transfer of electrons from the microbe to graphene electrodes in the fuel cells.
The miniaturization of electronics has resulted in an ever-increasing global market for portable devices. Correspondingly, it has become necessary to develop smaller and more lightweight power sources to operate these devices.
The Journal of Alloys and Compounds has published an article coauthored by the Institute of Solid State Chemistry and Mechanochemistry (the Ural Branch of the Russian Academy of Sciences), the Donostia International Physics Centre, and the HSE Tikhonov Moscow Institute of Electronics and Mathematics on the characteristics of cubic double perovskite oxides.
To realize a low-carbon society, effective utilization of natural energy is required as well as storing that generated energy.
Recently, green hydrogen has attracted a great deal of attention since it is a source of clean energy and promotes carbon neutrality. It can be generated without using fossil fuels.
As the cleanest renewable energy, hydrogen energy has attracted special attention in the research.
Tomorrow's cutting-edge technology will need electronics that can tolerate extreme conditions.
When it comes to fuel cell technology, protons are considered the next big thing. The subatomic exchange generates significant power that challenges modern solid-state fuel cell technology that is currently used to fuel space shuttles.
With an ever-strengthening commitment to sustainability, ABB and AFC Energy will partner on the testing and integration of fuel cells as part of the wider power portfolio for eMobility solutions and now also for data centers.
An international research group working at the Lawrence Berkeley National Laboratory (Berkeley Lab) of the U.S. Department of Energy (DOE) has gained a better understanding of lithium-rich battery materials with the help of a special X-ray instrument.
