1+ year, 3+ day ago  (364+ words) A Cornell University-led collaboration has hit the trifecta of sustainability technology: The group has developed a low-cost method to produce carbon-free "green" hydrogen via solar-powered electrolysis of seawater. A happy byproduct of the process? Potable water. The team's hybrid solar…...

10+ mon, 2+ week ago  (524+ words) As the world shifts toward sustainable energy sources, 'green hydrogen' - hydrogen produced without emitting carbon - has emerged as a leading candidate for clean power. Scientists have now developed a new iron-based catalyst that more than doubles the conversion efficiency of…...

9+ mon, 3+ week ago  (327+ words) The chemical reaction to produce hydrogen from water is several times more effective when using a combination of new materials in three layers, according to researchers at Link'ping University in Sweden. Hydrogen produced from water is a promising renewable energy…...

10+ mon, 2+ week ago  (281+ words) At HZB, a team led by Michelle Browne is developing sophisticated alternatives based on so-called MXenes. MXenes are flaky structures made of carbon and so-called transition metals. Catalytically active particles can adhere to the inner surfaces of MXenes, thereby enhancing…...

11+ mon, 4+ day ago  (548+ words) Researchers have developed two unique energy-efficient and cost-effective systems that use urea found in urine and wastewater to generate hydrogen. The unique systems reveal new pathways to economically generate 'green' hydrogen, a sustainable and renewable energy source, and the potential…...

10+ mon, 1+ week ago  (585+ words) A new study details processes that keep pollutants aloft despite a drop in emissions. Nitrates in the atmosphere reduce air quality and play an important role in climate change. An international team. .. Atmospheric chemistry keeps pollutants in the air Nitrates…...

2+ week, 2+ day ago  (706+ words) A University of Michigan study suggests that the nitrile and latex gloves scientists commonly use could be causing microplastics levels to appear higher than they actually are. Stearates are salt-based, soap-like substances added to disposable gloves to help them separate…...

1+ mon, 4+ day ago  (364+ words) A new study has revealed for the first time how different synthesis methods can profoundly impact the structural and functional properties of high entropy oxides, a class of materials with applications in everyday electronic devices. The study was published this…...

3+ day, 20+ hour ago  (302+ words) Atoms that absorb energy do not stay excited for long. They quickly return to a lower energy state by releasing light at a specific frequency, a process known as spontaneous emission. This behavior comes from the atom's interaction with the…...

1+ week, 1+ day ago  (129+ words) The Challenge of Light's Wavelength Why Molybdenum Diselenide Works So Well Turning Infrared Light Into Blue Light Another major advance lies in how the material was produced. Previously, thin layers of Mo Se2 were created using exfoliation -- a method similar to…...
