Leading nanoscientists created beautiful, tiled patterns with flat nanocrystals, but they were left with a mystery: Why did some sets of crystals arrange themselves in an alternating, herringbone style? To find out, they turned to experts in computer simulation at the University of Michigan ...
Understanding nanoparticles at atomic scale in 3 dimensions could improve materials
A team of scientists from the University of California, Los Angeles (UCLA) and Northwestern University has produced 3-D images and videos of a tiny platinum nanoparticle at atomic resolution that reveal new details of defects in nanomaterials that have not been seen before. Prior to this ...
Nitrogen doping of carbon-supported electrocatalysts is known to lead to a performance boost, although the reason why has not been clearly understood. Using principal component analysis (PCA) of electron energy loss spectroscopy (EELS) data, scientists from the Colorado School of Mines, ...
In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.Fifty days after scientists applied a single low dose of silver nanoparticles, the ...
Researchers devise way to safely see whether replacement cells are still alive
Researchers at Johns Hopkins have devised a way to detect whether cells previously transplanted into a living animal are alive or dead, an innovation they say is likely to speed the development of cell replacement therapies for conditions such as liver failure and type 1 diabetes. The study ...
Ordered nanocrystal arrays may provide a new platform to study and tailor the light-emitting properties of silicon
US scientists at the University of Texas at Austin and Cornell University have fabricated the first ordered arrays of silicon nanocrystals reported to date. Brian A. Korgel and colleagues developed a new chemical method to generate tiny silicon crystals—or quantum dots—with precisely ...
Low-power optical nanotweezers
Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power "optical nanotweezers" can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. "We already know that ...
A new use for atomically engineered gold
A University of Central Florida assistant professor has developed a new material using nanotechnology, which could help keep pilots and sensitive equipment safe from destructive lasers. UCF Assistant Professor Jayan Thomas, in collaboration with Carnegie Mellon University Associate Professor ...
By modifying the rate at which chemical reactions take place, nanoparticle catalysts fulfill myriad roles in industry, the biomedical arena and everyday life. They may be used for the production of polymers and biofuels, for improving pollution and emission control devices, to enhance ...
An MSU professor is part of team developing new method of removing phosphorous from wastewater
A professor at Michigan State University is part of a team developing a new method of removing phosphorous from our wastewater – a problem seriously affecting lakes and streams across the country. In addition, Steven Safferman, an associate professor of biosystems and agricultural ...
