Pouring flecks of rust into water usually makes it dirtier. But researchers have developed special iron oxide nanoparticles they call “smart rust” that actually makes it cleaner. Smart rust can attract many substances, including oil, nano- and microplastics, as well as the herbicide glyphosate, depending on the particles’ coating. And … [continued]
SAN FRANCISCO, Aug. 13, 2023 — In the refrigerated grocery store aisle, meat alternatives greatly outnumber plant-based seafoods. But more mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can deplete the supply and harm the environment. Today, researchers present a new approach for creating desirable … [continued]
Scientists report that they’ve designed superfast charging methods tailored to power different types of electric vehicle batteries in 10 minutes or less without harm. CHICAGO, Aug. 22, 2022 — Despite the growing popularity of electric vehicles, many consumers still hesitate to make the switch. One reason is that it takes … [continued]
CHICAGO, Aug. 22, 2022 — Studies have shown that pollution, whether from factories or traffic-snarled roads, disproportionately affects communities where economically disadvantaged people and Hispanic, Black and Asian people live. As technology has improved, scientists have begun documenting these disparities in detail, but information on daily variations has been lacking. … [continued]
When it comes to storing electricity from renewable sources, bacteria may have a bright future alongside lithium. This may be great news as demand grows for storing renewable electricity. Scientists report in the American Chemical Society journal Environmental Science & Technology Letters a first-of-its-kind development toward that goal: a rechargeable battery driven … [continued]
US researchers tease “white graphene” a little closer to commercial application in next-generation solar cells and other clean tech devices.
The announcement this morning by President Obama of a revised target for US methane emissions is not just another gimmick to shackle the American oil and gas industry. Nor is it new. Back in 1971, the world’s scientists thought that methane directly affected neither the climate nor the biosphere and … [continued]
Don’t go running for the medicine cabinet just yet when your car runs out of gas, but a research team at the University of Delaware is working on a low cost, high efficiency carbon capture system that uses an active ingredient in Pepto-Bismol to convert carbon dioxide into carbon monoxide. … [continued]
A very effective means of converting CO2 directly into methanol fuel has just been created, thanks to researchers from Université Laval. A single-step way to convert carbon dioxide directly into methanol has long been a goal of researchers in the field. “In the presence of oxygen, methanol combustion produces CO2 and … [continued]
Tina about one year ago wrote about Rice University research exploring the benefits from the use of boron in batteries. Rice has an update for us, reposted below (with minor changes). Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries. Calculations by … [continued]
