| Artificial intelligence breakthrough gives longer advance warning of ozone issues Posted: 24 Jun 2021 02:08 PM PDT Ozone levels in the earth's troposphere (the lowest level of our atmosphere) can now be forecasted with accuracy up to two weeks in advance, a remarkable improvement over current systems that can accurately predict ozone levels only three days ahead. The new artificial intelligence system could lead to improved ways to control high ozone problems and even contribute to solutions for climate change issues. |
| Recycling next-generation solar panels fosters green planet Posted: 24 Jun 2021 02:08 PM PDT Designing a recycling strategy for a new, forthcoming generation of photovoltaic solar cells - made from metal halide perovskites, a family of crystalline materials with structures like the natural mineral calcium titanate - will add a stronger dose of environmental friendliness to a green industry, according to new research. |
| Quantum dots keep atoms spaced to boost catalysis Posted: 24 Jun 2021 02:08 PM PDT Engineers use graphene quantum dots to trap transition metals for high atom loading in single atom catalysis. |
| Optical superoscillation without side waves Posted: 24 Jun 2021 02:08 PM PDT A sharp-edged aperture is a promising solution for eliminating side lobes from superoscillatory waves. |
| Muscling up with nanoparticle-based anti-inflammatory therapy Posted: 24 Jun 2021 01:17 PM PDT Researchers have developed a new approach in which specifically designed anti-inflammatory nanoparticles (NPs) that could be applied locally and selectively to chronically inflamed muscles severely affected or at more immediate risk of deterioration, and maybe difficult to reach with oral therapeutics. |
| Alaska infrastructure at risk of earlier failure Posted: 24 Jun 2021 01:16 PM PDT Roads, bridges, pipelines and other types of infrastructure in Alaska and elsewhere in the Arctic will deteriorate faster than expected due to a failure by planners to account for the structures' impact on adjacent permafrost, according to new research. |
| Light-harvesting nanoparticle catalysts show promise in quest for renewable carbon-based fuels Posted: 24 Jun 2021 01:16 PM PDT Researchers report that small quantities of useful molecules such as hydrocarbons are produced when carbon dioxide and water react in the presence of light and a silver nanoparticle catalyst. Their validation study - made possible through the use of a high-resolution analytical technique - could pave the way for CO2-reduction technologies that allow industrial-scale production of renewable carbon-based fuels. |
| Scientists can predict and design single atom catalysts for important chemical reactions Posted: 24 Jun 2021 11:15 AM PDT Guided by quantum chemical calculations, scientists design and test a new single atom catalyst that converts propane to propylene with 100% efficiency, with little deactivation by coking. If adopted by industry, the catalyst could save billions of dollars and stop millions of tons of carbon dioxide being emitted into the atmosphere. |
| Ethane proxies for methane in oil and gas emissions Posted: 24 Jun 2021 10:55 AM PDT Measuring ethane in the atmosphere shows that the amounts of methane going into the atmosphere from oil and gas wells and contributing to greenhouse warming is higher than suggested by the U.S. Environmental Protection Agency, according to an international team of scientists who spent three years flying over three areas of the U.S. during all four seasons. |
| New CRISPR 3.0 system for highly efficient gene activation in plants Posted: 24 Jun 2021 10:55 AM PDT Biologists have introduced a new and improved CRISPR 3.0 system in plants, focusing on gene activation.
