New Design For Developing Powerful Microbatteries
February 2, 2023 | Leave a Comment
University of Illinois Grainger College of Engineering researchers have created a high-voltage microbattery (> 9 V), with high-energy and -power density, unparalleled by any existing battery design. Translating electrochemical performance of large format batteries to microscale power sources has been a long-standing technological challenge, limiting the ability of batteries to power microdevices, microrobots and implantable […]

More Efficient Low Voltage Solar Powered Water Splitting
February 1, 2023 | Leave a Comment
A City University of Hong Kong research team has successfully mediated poor charge carrier transport at low voltage by adding phosphorus to a metal oxide catalyst. Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as an alternative fuel. However, their effectiveness is restricted at low voltage. Adding phosphorus reduced […]

Ten Times Better Solar Power Catalyst Makes Hydrogen
January 18, 2023 | Leave a Comment
University of Michigan scientists developed a new kind of solar panel achieving 9% efficiency in converting water into hydrogen and oxygen – mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind. But the biggest benefit is […]

Explaining How Biomass Could Replace All Of Aviation Fuel
January 5, 2023 | Leave a Comment
Arizona State University research shows a pathway toward full decarbonization of U.S. aviation fuel use by substituting conventional jet fuel with sustainably produced biofuels. The study found that planting the grass miscanthus on 23.2 million hectares of existing marginal agricultural lands – land that often lays fallow or is poor in soil quality – across […]
