Throughout the pandemic, air sensors watched during lockdowns as air pollution fell in residential and commercial areas, and then as pollution rose again with reopenings. The changing levels, the researchers found, which behaved differently in residential and commercial parts of the city, show where pollution is coming from and how it might change in the future under different policies.
Scientists at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, have found a way to simultaneously increase the strength and ductility of an alloy by introducing tiny precipitates into its matrix and tuning their size and spacing. The precipitates are solids that separate from the metal mixture as the alloy cools. The results will open new avenues for advancing structural materials.
Software to help towns and cities use street-planting to reduce citizens' exposure to air pollution has been developed by researchers at the University of Birmingham.
A 15-year reciprocal transplant study on Guam's native cycad tree, Cycas micronesica, by the Plant Physiology Laboratory at the University of Guam's Western Pacific Tropical Research Center has revealed that acute adaptation to local soil conditions occurs among the tree population and is important in the survival rate of transplanted cycads.
Vertical greenery 'planted' on the exterior of buildings may help to buffer people against stress, a Nanyang Technological University, Singapore (NTU Singapore) study has found.
Researchers have developed a new strategy to characterise polymeric transition metal species in acidic solution that has proved promising as an effective method for understanding the polymerisation nature of transition metal (even Ni, Co, REEs), resulting in an efficient method for high-purity metal recovery applications.
Our changing relationship with cash and dramatically reduced foot traffic in CBDs around the globe has prompted street performers to find different ways to generate income and sustain their careers.
Fundamental changes in our economies are required to secure decent living standards for all in the struggle against climate breakdown, according to new research.
Scientists from the National University of Science and Technology "MISiS" (NUST MISIS) in cooperation with their colleagues from the Siberian Federal University and the Research and Production Centre of Magnetic Hydrodynamics (Krasnoyarsk) have developed a technology for producing a unique heat-resistant aluminium alloy with improved durability. According to the researchers, this new alloy could replace more expensive and heavier copper conductors in aircraft and high-speed rail transport. The study results were published in an interdisciplinary, peer-reviewed journal, the Materials Letters.
When the summer sun blazes on a hot city street, our first reaction is to flee to a shady spot protected by a building or tree. A new study is the first to calculate exactly how much these shaded areas help lower the temperature and reduce the "urban heat island" effect.
