Converting dinitrogen into ammonia is critical for making fertilizer. Conventional conversion processes use adenosine triphosphate (ATP). Researchers are now working on processes that instead use sunlight, which reduces energy use and greenhouse gas production relative to the ATP process. In this research, scientists created a unique biohybrid that couples nanocrystals to nitrogen-catalyzing enzymes to produce ammonia using sunlight.
Earth’s atmosphere holds an ocean of fresh water. Extracting some of that moisture is seen as a potential way to provide clean drinking water to billions of people globally who face chronic shortages. A prototype device developed by University of Utah engineers for the U.S. Army harvests drinking water from atmosphere, even in arid places.
Researchers still need to get a better understanding of how metal-organic frameworks function, especially when embedded in polymers. Reporting in ACS Applied Materials & Interfaces, researchers have now developed and characterized nitric oxide-storing MOFs embedded in a thin film with novel antibacterial potential.
Scientists recently investigated the factors that control fluorescent light signals from metal organic frameworks (MOFs). The light may turn on due to structural changes in the MOF and turn off due to reorganization of the electrons in the MOF. Understanding these factors advances researchers’ ability to design and use MOFs as chemical sensors.
