A research team led by Professor Yutaka Amao from the Research Center for Artificial Photosynthesis and graduate student Mika Takeuchi, from the Osaka Metropolitan University Graduate School of Science, have succeeded in synthesizing fumaric acid from CO2, a raw material for plastics, powered — for the first time — by sunlight. Their findings were published …

This process of self-cleaning is essential to remove gaseous pollutants and regulate greenhouse gases such as methane from the atmosphere. Researchers were already aware that the atmosphere had this ‘self-cleaning’ ability, but in a new study from the University York, experts have now shown a new process that increases the ability of the marine atmosphere …

Globally, the Haber-Bosch process for making ammonia uses about 1% of all fossil fuels and produces 1% of all carbon dioxide emissions, making it a major contributor to climate change. Now, University of California, Berkeley, chemists have taken a big step toward making ammonia production more environmentally friendly: a “greener” ammonia for “greener” fertilizer. A …

Ionocaloric cooling takes advantage of how energy, or heat, is stored or released when a material changes phase — such as changing from solid ice to liquid water. Melting a material absorbs heat from the surroundings, while solidifying it releases heat. The ionocaloric cycle causes this phase and temperature change through the flow of ions …

Tengfei Luo, the Dorini Family Professor of Energy Studies at the University of Notre Dame, and postdoctoral associate Seongmin Kim have devised a transparent coating for windows that does just that. The coating, or transparent radiative cooler (TRC), allows visible light to come in and keeps other heat-producing light out. The researchers estimate that this …

Catalysts accelerate chemical reactions without being consumed by themselves. A large number of reactions in nature and industry only work thanks to their help. For example, catalysts are used in around 80 percent of all chemical production processes and also play an important role in technologies for the chemical storage of hydrogen. In most cases, …

This breakthrough has been led by Professor Kyoung Jin Choi and his research team in the Department of Materials Science and Engineering at UNIST, in collaboration with Professor Jung-Kun Lee and his research team from the University of Pittsburgh in the United States. In the work, the research team systematically demonstrated that a combination of …

“There are a bunch of ecogeographic rules that scientists use to explain trends that we see again and again in nature,” says Noé de la Sancha, a research associate at Chicago’s Field Museum, an assistant professor of Environmental Science and Studies at DePaul University, and the paper’s corresponding author. “With this paper, I think we …
