The formation and thickening of internal and surface barriers during battery charge and discharge cycles limits electrochemical reactions in a lithium-ion battery with an iron oxide electrode.
Scientists today announced a major new finding about how matter behaves in the extreme conditions of the sun's atmosphere. Their work has shed new light on the exotic but poorly understood 'fourth state of matter,' known as plasma, which could hold the key to developing safe, clean and efficient nuclear energy generators on Earth.
While 160 companies around the world have committed to use '100% renewable energy,' that does not mean '100% carbon-free energy.' The difference will grow as power grids become less reliant on fossil power, according to a new Stanford study. Entities committed to fighting climate change can and should measure the environmental benefits of their renewable strategies accurately, the authors write.
One of the big issues with sustainable energy systems is how to store electricity that's generated from wind, solar and waves. At present, no existing technology provides large-scale storage and energy retrieval for sustainable energy at a low financial and environmental cost. Engineered electroactive microbes could be part of the solution.
Researchers find higher concentrations of trace metals such as barium in the hair and urine of 29 pregnant women living near fracking wells in British Columbia, Canada.
If you want to make your home as energy-efficient and green as possible, should you use gas or electric for your heating and cooling needs?
While methane pollution caused by natural gas production in Pennsylvania is underestimated by the US Environmental Protection Agency, natural gas still has half the carbon footprint of underground coal mining, according to an international team of researchers.
Wasted food can be affordably turned into a clean substitute for fossil fuels. New technology developed by researchers at the University of Waterloo engineers natural fermentation to produce a biodegradable chemical that can be refined as a source of energy.
Based on high-performance liquid-like materials, scientists from the Shanghai Institute of Ceramics and Northwestern University innovatively fabricated a Cu2Se/Yb0.3Co4Sb12 thermoelectric module with eight n-type Ni/Ti/Yb0.3Co4Sb12 legs and eight p-type Ni/Mo/Cu2Se legs.
Chemists at the University of Illinois have successfully produced fuels using water, carbon dioxide and visible light through artificial photosynthesis. By converting carbon dioxide into more complex molecules like propane, green energy technology is now one step closer to using excess CO2 to store solar energy -- in the form of chemical bonds -- for use when the sun is not shining and in times of peak demand.
