Current Nanotechnology News Events, Discoveries and Articles
New ORNL process brings nanoparticles into focus
Scientists can study the biological impacts of engineered nanomaterials on cells within the body with greater resolution than ever because of a procedure developed by researchers at the Department of Energy's Oak Ridge National Laboratory. (2008-06-24)
Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects. (2008-06-17)
'Nanoglassblowing' seen as boon to study of individual molecules
While the results may not rival the artistry of glassblowers in Europe and Latin America, researchers at the National Institute of Standards and Technology (NIST) and Cornell University have found beauty in a new fabrication technique called "nanoglassblowing" that creates nanoscale (billionth of a meter) fluidic devices used to isolate and study single molecules in solution-including individual DNA strands. The novel method is described in a paper posted online next week in the journal Nanotechnology. (2008-06-13)
Brown researchers work toward ending cartilage loss
Scientists have long wrestled with how to aid those who suffer cartilage damage and loss. One popular way is to inject an artificial gel that can imitate cartilage's natural ability to act as the body's shock absorber. But that solution is temporary, requiring follow-up injections. (2008-06-04)
Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. (2008-06-02)
By Adding Graphene, Researchers Create Superior Polymer
Researchers at Northwestern University and Princeton University have created a new kind of polymer that, because of its extraordinary thermal and mechanical properties, could be used in everything from airplanes to solar cells. (2008-05-20)
Designer Isotopes Push the Frontier of Science
Designer labels have a lot of cachet, a principle that's equally true in fashion and physics. (2008-05-12)
Made-to-order isotopes hold promise on science's frontier
Designer labels have a lot of cachet - a principle that's equally true in fashion and physics. (2008-05-09)
Are nanobots on their way?
The first real steps towards building a microscopic device that can construct nano machines have been taken by US researchers. Writing in the peer-reviewed publication, International Journal of Nanomanufacturing from Inderscience Publishers, researchers describe an early prototype for a nanoassembler. (2008-04-29)
Copper nanowires grown by new process create long-lasting displays
A new low-temperature, catalyst-free technique for growing copper nanowires has been developed by researchers at the University of Illinois. The copper nanowires could serve as interconnects in electronic device fabrication and as electron emitters in a television-like, very thin flat-panel display known as a field-emission display.
