Researchers at Tokyo Institute of Technology have developed a ruthenium-based perovskite catalyst that shows strong activity even at low temperatures (down to 313 K). The reusable catalyst does not require additives, meaning that it can prevent the formation of toxic by-products. The oxidation of sulfides is a commercially important process with broad applications ranging from chemicals production to environmental management.
Understanding gas flames' response to acoustic perturbations at high pressure should make next-generation turbines safer and more efficient.
Kyoto University researchers have developed a new approach to control the fabrication of soft, porous materials, overcoming a primary challenge in materials science.
Washington State University researchers have created a sustainable alternative to traditional concrete using coal fly ash, a waste product of coal-based electricity generation.
Contact with greenspace is known to have beneficial effects for mental health. A new study by the Barcelona Institute for Global Health (ISGlobal) suggests that it may also play a positive role against cognitive decline in elderly. In particular, this research published in Environmental Health Perspectives shows that the loss in cognitive functions expected as part of the aging process is slightly slower in people who live in greener neighborhoods.
Engineers with the University of Cincinnati are leveraging a partnership with Wright-Patterson Air Force Base to create clothing that can charge your cell phone. What makes this possible are the unique properties of carbon nanotubes: a large surface area that is strong, conductive and heat-resistant.
Researchers at the Universitat Autònoma de Barcelona have mapped Barcelona and its conurbation using a new methodology based on urbanism activist Jane Jacobs' ideas on how cities should be configured to become vital spaces.
China broke into the world's top 20 most-innovative economies as Switzerland retained its No. 1 spot in the Global Innovation Index (GII) published annually by Cornell University, INSEAD, the World Intellectual Property Organization, and GII Knowledge Partners. The GII ranks 126 economies based on 80 indicators, ranging from intellectual property filing rates to scientific and technical publications, helping global decision makers better understand how to stimulate innovative activity that drives economic and human development.
For many Americans, highly processed foods are on the menu for breakfast, lunch, and dinner. Even when the raw materials -- grains, for example -- are high in vitamins and health-promoting phenolic compounds, processing can rob the final product of these nutrients. In a set of recent studies, University of Illinois scientists reveal what happens to cancer-fighting phenolic acids in corn when it is processed into cornflakes.
A new microscopy technique allows researchers to track microstructural changes in real time, even when a material is exposed to extreme heat and stress. Recently, researchers show that a stainless steel alloy called alloy 709 has potential for elevated temperature applications such as nuclear reactor structures.
