| Reducing the melting of Greenland ice cap using solar geoengineering? Posted: 07 Jul 2021 01:05 PM PDT Injecting sulphur into the stratosphere to reduce solar radiation and stop the Greenland ice cap from melting: An interesting scenario, but not without risks. Climatologists have looked into the matter and have tested one of the scenarios put forward using the MAR climate model. The results are mixed. |
| Energycane produces more biodiesel than soybean at a lower cost Posted: 07 Jul 2021 11:07 AM PDT Bioenergy from crops is a sustainable alternative to fossil fuels. New crops such as energycane can produce several times more fuel per acre than soybeans. Yet, challenges remain in processing the crops to extract fuel efficiently. Four new studies explore chemical-free pretreatment methods, development of high-throughput phenotyping methods, and commercial-scale techno-economic feasibility of producing fuel from energycane in various scenarios. |
| Cutting through noise for better solar cells Posted: 07 Jul 2021 08:25 AM PDT Physicists used cross-correlation noise spectroscopy to measure miniscule fluctuations in electrical current flowing between materials inside silicon solar cells. The researchers identified crucial electrical noise signals that are completely invisible to conventional noise-measuring methods. They were also able to pinpoint the likely physical processes causing the noise, which often results in a loss of energy and lower efficiency. The technique is an important new tool to improve material interfaces for a better solar cell. |
| Quantum laser turns energy loss into gain? Posted: 07 Jul 2021 08:24 AM PDT Scientists have fabricated a laser system that generates highly interactive quantum particles at room temperature. Their findings could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases. |
| New clues to why there's so little antimatter in the universe Posted: 07 Jul 2021 08:23 AM PDT New research shows radioactive molecules are sensitive to subtle nuclear phenomena. The molecules might help physicists probe violation of the most fundamental symmetries of nature, including why the universe contains relatively little antimatter. |
| Posted: 06 Jul 2021 12:30 PM PDT Researchers have developed a method that may lead to new types of displays based on structural colors. The discovery opens the way to cheap and energy-efficient color displays and electronic labels. |
| Making computer servers worldwide more climate friendly Posted: 06 Jul 2021 10:31 AM PDT An elegant new algorithm can significantly reduce the resource consumption of the world's computer servers. Computer servers are as taxing on the climate as global air traffic combined, thereby making the green transition in IT an urgent matter. The researchers expect major IT companies to deploy the algorithm immediately. |
| Developing new techniques to build biomaterials Posted: 06 Jul 2021 10:28 AM PDT Scientists have developed an approach that could help in the design of a new generation of synthetic biomaterials made from proteins. The biomaterials could eventually have applications in joint repair or wound healing as well as other fields of healthcare and food production. |
