Two NJIT researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale. "Numerical simulation of ejected molten metal nanoparticles liquified by laser irradiation: Interplay of geometry and dewetting," appeared in Physical Review Letters (July 16, 2013). The evolution of fluid drops deposited on solid substrates has been a focus of large research effort for decades, said co-author Shahriar Afkhami,...

Salt Savior Of Tech Industry
2013-08-09 10:48:25

Brett Smith for redOrbit.com - Your Universe Online Silicon nanostructures are used in everything from electronics to energy storage, but their production process is complex and costly. However, engineers from Oregon State University have identified a compound sitting in every kitchen that could reduce production costs and boost mass production of the tiny structures: table salt. According to a recently published report in the journal Scientific Reports, sodium chloride can melt and...

The Science Behind A Self-assembled Nano-carbon Helix
2013-05-16 12:42:51

University of Vienna Nanotechnology draws on the fabrication of nanostructures. Scientists have now succeeded in growing a unique carbon structure at the nanoscale that resembles a tiny twirled moustache. Their method might lead the way to the formation of more complex nano-networks. Researchers of the Electronic Properties of Materials Group at the Faculty of Physics (University of Vienna) and their international collaborators have published their results in the new open access journal of...

Caltech Invents Microscope Which Captures Motion Of DNA Structures In Space And Time
2013-02-11 13:32:51

California Institute of Technology (Caltech) Every great structure, from the Empire State Building to the Golden Gate Bridge, depends on specific mechanical properties to remain strong and reliable. Rigidity–a material's stiffness–is of particular importance for maintaining the robust functionality of everything from colossal edifices to the tiniest of nanoscale structures. In biological nanostructures, like DNA networks, it has been difficult to measure this stiffness, which...

Scientists Alter Rainbow Color Order
2012-11-20 20:57:41

Lee Rannals for redOrbit.com — Your Universe Online King's College London researchers reported in the journal Nature's Scientific Reports they have demonstrated how to separate colors and create "rainbows" using nanoscale structure on a metal surface. The team was able to trap light of different colors at different positions of a nanostructured area using specially designed nanostructures. Depending on the geometry of the nanostructure, a trapped rainbow could be created on a...

[ Watch the Video ] Stir this clear liquid in a glass vial and nothing happens. Shake this liquid, and free-floating sheets of protein-like structures emerge, ready to detect molecules or catalyze a reaction. This isn´t the latest gadget from James Bond´s arsenal–rather, the latest research from the U. S. Department of Energy (DOE)´s Lawrence Berkeley National Laboratory (Berkeley Lab)  scientists unveiling how slim sheets of protein-like structures...

Researchers at Yale University are studying how two types of nanoscale structures on the feathers of birds produce brilliant and distinctive colors. The researchers are hoping that by borrowing these nanoscale tricks from nature they will be able to produce new types of lasers–ones that can assemble themselves by natural processes. The team will present their findings at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2011, taking place in San Jose, Calif. next...

Why Carbon Nanotubes Spell Trouble For Cells
2011-09-19 04:10:52

  [ View the Video ] It's been long known that asbestos spells trouble for human cells. Scientists have seen cells stabbed with spiky, long asbestos fibers, and the image is gory: Part of the fiber is protruding from the cell, like a quivering arrow that's found its mark. But scientists had been unable to understand why cells would be interested in asbestos fibers and other materials at the nanoscale that are too long to be fully ingested. Now a group of researchers at Brown...

A delicate balance of atomic forces can be exploited to make nanoparticle superclusters that are uniform in size–an attribute that's important for many nanotech applications but hard to accomplish, University of Michigan researchers say. The same type of forces are at work bringing the building blocks of viruses together, and the inorganic supercluster structures in this research are in many ways similar to viruses. U-M chemical engineering professors Nicholas Kotov and Sharon...
