Researchers have streamlined and simplified a process that uses extracts from seeds of Moringa oleifa trees to purify water, reducing levels of harmful bacteria by 90 percent to 99 percent. The hardy trees that are drought resistant are cultivated widely throughout many countries of Africa, Asia, and Latin America.
Germany comes in first in a new energy efficiency ranking of the world's major economies, followed by Italy, the European Union as a whole, China, and France, according to the 2014 International Energy Efficiency Scorecard published by the nonprofit American Council for an Energy-Efficient Economy (ACEEE).
Researchers are using new magnetic materials to develop revolutionary electrical motors and generators which promise significant energy savings. They have used the new motors to develop patented highly efficient water pump systems with potential widespread application.
Oil produced from biomass - such as wood chips or plant residues - seldom has the same quality and energy content as 'classical' crude oil. A new, simple catalyst improves the quality of this oil before it is even transported to the refinery.
Scientists from the University of Southampton have helped to create a new map, which shows the impact climate change could have on the whole planet by the end of the century, if carbon emissions continue to increase.
A 25-year-long study provides the first quantitative measurement of in situ calcium-magnesium silicate mineral dissolution by ants, termites, tree roots, and bare ground. This study reveals that ants are one of the most powerful biological agents of mineral decay yet observed. It may be that an understanding of the geobiology of ant-mineral interactions might offer a line of research on how to 'geoengineer' accelerated carbon dioxide consumption by calcium-magnesium silicates.
Scientists have developed a method for improving the catalysis of water-splitting reactions used for storing wind and solar energy. The method chemically peels off the outermost surface of a catalyst, thereby maximizing its active surface for the reaction.
A new study created a life-cycle assessment (LCA) model to provide some estimates that might help guide research directions to faster marketplace success. The scientists constructed a model simulation of a large-scale PEC-based hydrogen production facility, using what is known currently about the technology as well as projections of future performance.
A new study has found that the dispersant compound DOSS, which decreases the size of oil droplets and hampers the formation of large oil slicks, remains associated with oil and can persist in the environment for up to four years.
