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.
Results from phase two clinical trials at UT Southwestern Medical Center showed that a suspension of gold nanocrystals taken daily by patients with multiple sclerosis (MS) and Parkinson’s disease (PD) significantly reversed deficits of metabolites linked to energy activity in the brain and resulted in functional improvements.
Researchers from the National University of Singapore (NUS) have developed a transmissive thin scintillator using perovskite nanocrystals, designed for real-time tracking and counting of single protons.
A multi-institution team of researchers led by Indiana University chemist Sara Skrabalak has been awarded $1.8 million from the NSF to establish a research center focused on transforming nanocrystal discovery and design.
By stabilizing perovskite nanocrystals in a metal-organic framework (MOF), a research team has synthesized light-emitting diodes (LEDs) that exploit the performance benefits of the material while avoiding previous roadblocks.
Researchers have combined two or three types of nanoparticles to produce new materials with structures known as superlattices. In some instances, the structures display fundamental new properties such as superfluorescence. The researchers’ discovery is reported in the journal Nature.
An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano “Lego bricks” interact with each other with forces vastly different and much weaker than those holding atoms and ions together, they form crystals all by themselves, the structures of which resemble the ones of natural minerals. These new mega-crystals or superlattices that are depicted on the cover of the latest issue of “Nature” exhibit unique properties such as superfluorescence – and may well usher in a new era in materials science
