Researchers found that vegetation in a section of central L.A. offsets a surprising 60% of fossil fuel emissions (CO2), particularly during the growing season. The first-of-its-kind study used a dense array of air-quality sensors to track carbon emissions and absorption in real time, providing a more detailed picture than traditional methods. The findings suggest that expanding urban greenery could play a bigger role in reducing the city’s carbon footprint than previously thought. The USC-led approach could serve as a model for other cities aiming to monitor and cut emissions.
Grouting is a widely used construction technique that involves injecting stabilizing materials into soil to ensure structural stability, which is especially beneficial in earthquake-prone regions. Now, scientists from Japan have developed an innovative, carbon-neutral grout made from waste fluids of geothermal energy harvesting systems. Their new material shows a 50% increase in liquefaction resistance compared to conventional grouts, while also addressing environmental concerns associated with the construction industry.
Heteroepitaxial growth technology has made it possible to create larger diamond substrates, opening new opportunities for industrial-scale production of diamond quantum sensors. A research team led by Institute of Science Tokyo in collaboration with Shin-Etsu Chemical Co., Ltd. and the National Institute of Advanced Industrial Science and Technology, successfully fabricated large-area (111)-orientated diamond crystal substrates on heterogeneous (non-diamond) substrates, demonstrating the potential for industrialization of precise, noise-resistant current measurements for electric vehicle battery monitoring.
Per- and polyfluoroalkyl substances (PFAS) are known as forever chemicals because of their extreme persistence. These compounds have useful properties including durability and waterproofing, so they’re commonly used in consumer products like food packaging and cosmetics, as well as industrial processes. But PFAS’ potential negative impacts on human health are driving the search for potentially safer substitutes. Now, researchers publishing in ACS’ Environmental Science & Technology propose alternatives for many applications.
