Researchers at the Ruhr-Universität Bochum have discovered why bioelectrodes containing the photosynthesis protein complex photosystem I are not stable in the long term. Such electrodes could be useful for converting light energy into chemical energy in an environmentally friendly way. However, the proteins, which are stable in nature, are not functional in semi-artificial systems in the long term because reactive molecules are formed that damage the photosystem I.
Indigenous communities are rejecting non-indigenous energy projects in favor of community-led sustainable energy infrastructure.
Thermoelectric materials, heated under high magnetic fields, could produce record levels of energy, suggests a new study by MIT researchers.
Last September, a massive new region of magnetic field erupted on the Sun's surface next to an existing sunspot. The powerful collision of magnetic fields produced a series of potent solar flares, causing turbulent space weather conditions at Earth. These were the first flares to be captured, in their moment-by-moment progression, by New Jersey Institute of Technology's (NJIT) recently expanded Owens Valley Solar Array (EOVSA).
Without careful management, distributed energy resources have the potential to cause unreliable power delivery, or even outages, and lead utility companies to overcharge customers. A new index will help ISOs and utilities account for uncertainties introduced by both the electricity market and DERs so utility companies can balance the distribution grid and find the fairest customer rates.
A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.
Carbon aerogels are ultralight, conductive materials, which are extensively investigated for applications in supercapacitor electrodes in electrical cars and cell phones. Chinese scientists have now found a way to make these electrodes sustainably. The aerogels can be obtained directly from cellulose nanofibrils, the abundant cell-wall material in wood, finds the study reported in the journal Angewandte Chemie.
Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research.
Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
Carbon nanotubes are supermaterials that can be stronger than steel and more conductive than copper, but they're rare because, until now, they've been incredibly expensive.
