Scientists are reporting development of a new form of buckypaper, which eliminates a major drawback of these sheets of carbon nanotubes -- 50,000 times thinner than a human hair, 10 times lighter than steel, but up to 250 times stronger -- with potential uses ranging from body armor to next-generation batteries. Their report appears in the journal ACS Nano.

Often the sum is greater than its parts. Using an atomic force microscope as a “crane”, Ludwig Maximilian University of Munich researchers have succeeded in bringing two biomolecules together to form an active complex – with nanometer precision and built-in quality control.

To modify a metal surface at the scale of atoms and molecules — for instance to refine the wiring in computer chips or the reflective silver in optical components — manufacturers shower it with ions. While the process may seem high-tech and precise, the technique has been limited by the ...

A new study led by University of Kentucky researchers shows a new way to precisely detect a single chemical at extremely low concentrations and high contamination.

A new study shows that the availability of hydrogen plays a significant role in determining the chemical and structural makeup of graphene oxide, a material that has potential uses in nano-electronics, nano-electromechanical systems, sensing, composites, optics, catalysis and energy storage.

Rapid DNA sequencing may soon become a routine part of each individual’s medical record, providing enormous information previously sequestered in the human genome’s 3 billion nucleotide bases. This week’s NEWSFOCUS section of the journal Science describes recent advances in sequencing technology.

(Phys.org) -- By taking advantage of graphene’s favorable electrical and optical properties, and then adding an organic dopant, researchers have achieved the highest power conversion efficiency yet for a graphene-based solar cell. The 1.9% power conversion efficiency of the undoped devices increases by more than four times to 8.6% after ...

A pioneering study to gauge the toxicity of quantum dots in primates has found the tiny crystals to be safe over a one-year period, a hopeful outcome for doctors and scientists seeking new ways to battle diseases like cancer through nanomedicine.
