Inspired by the aroma of ancient paper, scientists are documenting the odours of a stately British home in a bid to preserve historical smells for posterity.
Researchers have proven a method for multiplying laser power using diamond, demonstrating that a laser similar to the Star Wars ‘superlaser’ may no longer remain in science fiction. Continue reading Star Wars ‘superlaser’ comes closer to reality!
Scientists have developed an ultra-thin gel-like coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries.
“Our approach is general, in that it can be integrated with virtually any kind of sulfur electrode to increase cycling stability,” said lead investigator of the study Hailiang Wang, Assistant Professor of Chemistry at Yale University in New Haven, Connecticut, US.
In a study published online in the Proceedings of the National Academy of Sciences, the researchers described the new material which can be applied to any sulfur cathode.
A cathode is the positive terminal on a battery.
Sulfur cathodes coated with the material can be stably discharged and recharged for more than 1,000 cycles, enhancing the battery’s efficiency and number of cycles, according to the researchers.
“The developed film is so thin and light it will not affect the overall size or weight of the battery, and thus it will function without compromising the energy and power density of the device,” Wang said. Continue reading Gel-like coating can boost lithium-sulfur battery performance
Saturn moon Enceladus’s hidden sea might be closer to the surface than previously thought, suggests a new study that found the south polar region of the moon to be warmer than expected just a few feet below its icy surface. Continue reading Saturn’s moon Enceladus may have water closer to surface
Japanese authorities sent a robot to the Fukushima nuclear plant on Tuesday to measure radiation levels inside and evaluate its condition ahead of a future dismantling of a reactor. Continue reading Japan sends robot to study radiation in n-reactor
Certain words used on social media platforms like Flickr can warn us about extreme weather events before they happen—such as hurricanes, storms and floods, suggests new research. Continue reading Social media posts can help predict floods, hurricanes
Researchers have developed an algorithm that lets robots ask for clarification when they are not sure what exactly a person wants them to fetch, especially when there are lots of very similar objects in close proximity to each other. Continue reading This robot can ask for clarification
