Researchers from Carnegie Mellon University's Mellon College of Science and College of Engineering have developed a semiliquid lithium metal-based anode that represents a new paradigm in battery design. Lithium batteries made using this new electrode type could have a higher capacity and be much safer than typical lithium metal-based batteries that use lithium foil as anode. The interdisciplinary research team published their findings in the current issue of Joule.
Japanese researchers are poised to reboot the field of aromatic-fused porphyrin sensitizers for dye-sensitized solar cells, the most efficient solar technology available at present.
Researchers have conducted the first analysis of Bitcoin power consumption based on empirical data from IPO filings and localization of IP addresses. They found that the cryptocurrency's carbon emissions measure up to those of Kansas City -- or a small nation. The study, published June 12 in the journal Joule, suggests that cryptocurrencies contribute to global carbon emissions, an issue that must be considered in climate change mitigation efforts.
Scientists at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences have developed a chemocatalytic approach to convert cellulose into ethanol in a one-pot process by using a multifunctional Mo/Pt/WOx catalyst. This approach opens up an alternative avenue for biofuel production.
A group of researchers from Japan has recently discovered a novel enzyme from a soil fungus. In their study, they speculate that this enzyme plays important roles in the soil ecosystem, and then describe its structure and action.
University of Colorado Boulder researchers have developed nanobio-hybrid organisms capable of using airborne carbon dioxide and nitrogen to produce a variety of plastics and fuels, a promising first step toward low-cost carbon sequestration and eco-friendly manufacturing for chemicals.
By using energy-efficient buildings and distributing means of energy generation throughout buildings, sustainable communities can achieve a yearly net zero energy balance. However, this glosses over the local energy fluctuations that can challenge the supporting power grid. Researchers have now integrated power grid considerations into the model of a planned net zero energy district and examined energy fluctuations at 15-minute intervals. The analysis and recommendations are presented in the Journal of Renewable and Sustainable Energy.
New insights about how to understand and ultimately control the chemistry of ignition behavior and pollutant formation have been discovered in research led by Sandia National Laboratories. The discovery eventually will lead to cleaner, more efficient internal combustion engines.
Scientists have identified specific parts of genetic code within switchgrass that could contribute to larger switchgrass harvests while reducing potential crop weaknesses.
The economic value of demand response that adjusts the power consumption has not been clarified. A control method for maximizing cost-effectiveness of demand response is developed. Using this method, the optimal power consumption can be calculated based on the prediction of the power generation cost and the demand.
