Despite uncertainties, cellulosic biofuels still a win for ground transportation
2024-02-22 21:32:26
Despite the fervor around electric vehicles and their potential to reduce the transportation sector's carbon footprint, 2023 projections suggest EVs won't edge out gas-powered vehicles for decades to come. With conventional vehicles likely to dominate the ground fleet for the foreseeable future, University of Illinois Urbana-Champaign experts say cellulosic biofuels shouldn't be discounted.
How residual materials can become high-performance construction products
2024-02-22 21:32:26
When it comes to sustainable development, the construction industry faces great challenges. In the ReMatBuilt project, experts from the Fraunhofer Institute for Wood Research, Wilhelm-Klauditz-Institut, WKI and their partners are proving that the tasks associated with this can be solved with high-performance construction materials made of recycled and waste materials. They presented their solutions to specialist audiences at the Hannover Messe Preview on February 21, 2024.
Q&A: ChatGPT acts more altruistically, cooperatively than humans
2024-02-22 21:32:25

Adaptive fusion of structure and attribute-guided polarized communities search
2024-02-22 18:29:24
The exploration of polarized communities, which consist of two antagonistic subgraphs and include a set of query nodes, is a crucial task in community search on signed networks. Most existing methods either predominantly rely on topological structure while disregarding node attributes or tend to prioritize the global identification of all polarized communities. Thus, they fail to consider two crucial insights.

Thermoelectric technologies can help power a zero-carbon future
2024-02-22 17:37:19
Thermometers are an under-appreciated marvel of human ingenuity built upon an understanding of relatively simple physical principles. Mercury and alcohol thermometers rely on the volume of liquids growing or shrinking in reaction to temperature change. Contactless infrared thermometers, by contrast, read the thermal radiation emitted by any object, from frying pans to the human body.
