The device integrates a carbon capture system with an ethylene conversation system for the first time. And, the system not only runs on electricity, but it also removes more carbon from the environment than it generates — making it what scientists call net-negative on carbon emissions. Among manufactured chemicals worldwide, ethylene ranks third for carbon …

They say their invention offers a promising way to tap into a plentiful supply of cheap hydrogen fuel for transportation and other sectors, which could radically reduce carbon emissions and help fight climate change. By using high-frequency vibrations to “divide and conquer” individual water molecules during electrolysis, the team managed to split the water molecules …

A new perspective published today, December 5, in the Proceedings of the National Academy of Sciences (PNAS) titled “Harnessing island-ocean connections to maximize marine benefits of island conservation” recognizes the critical link between island and marine ecosystems and identifies island and near-shore marine environmental characteristics that promote strong linkages in these ecosystems around the world. …

The study, published in Environmental Science & Technology, indicated that large numbers of microplastics in Auckland’s air are of extremely small sizes, raising concerns about the potential for particles to be inhaled and accumulate in the human body. Researchers around the world are likely to have dramatically undercounted airborne microplastics, says lead author Dr Joel …

These durable, flexible solar cells, which are much thinner than a human hair, are glued to a strong, lightweight fabric, making them easy to install on a fixed surface. They can provide energy on the go as a wearable power fabric or be transported and rapidly deployed in remote locations for assistance in emergencies. They …

For ferrate to work best, however, it needs to be combined with other compounds or excited by light energy. Now, using a technique involving ultra-fast laser and X-ray pulses, a team of University of Rhode Island researchers has revealed new details about the chemical reaction that occurs when ferrate is exposed to visible and ultraviolet …

Their calls are based on a new study, recently published in the journal Conservation Letters, led byscientists from Nekton, the Western Indian Ocean (WIO) and the University of Oxford. This confirms for the first time that deep reef habitats, notably in the WIO, are largely unprotected despite being under threat from a multitude of stressors, …

“We used a unique set of climate model simulations that span the Holocene, the past 12,000 years, and accounted for changes in the frequency of El Niño flavors, the three preferred locations in which the peak of warming during different El Niño events occur — eastern Pacific, central Pacific, and coastal,” said Christina Karamperidou, lead …

Researchers in UCI’s Department of Materials Science and Engineering and Johns Hopkins University’s Department of Biology used high-resolution electron microscopy and advanced spectroscopic imaging techniques to gain a precise understanding of how microorganisms modify both naturally occurring minerals and synthetically made nanoceramics. A key factor, according to the scientists, is that cyanobacteria produce biofilms that …

Using bright green lasers and camera equipment, a team of CU Boulder engineers ran an experiment to reveal how tiny water droplets, invisible to the naked eye, are rapidly ejected into the air when a lid-less, public restroom toilet is flushed. Published in Scientific Reports, it is the first study to directly visualize the resulting …
