- Nanoscience
A new twist on nanowire growth leads to stunning structures.
- How to dissolve your carbon nanotubes
Although carbon nanotubes are generally regarded as insoluble in all solvents.
- Souped-up nanomotors
Drop a bimetal nanowire, composed of a segment of gold and a segment of platinum, into a solution of aqueous hydrogen peroxide and the tiny rod will chug along at about 8 m/second.
- Nano-biointeractions need more study
A coordinated global research effort is needed to predict how engineered nanoparticles will interact with biological systems.
- Firing Up The Tank With Nanoparticles
Aluminum or aluminum oxide particles could help improve fuel efficiency.
- Nano TV Series Debuts
Public broadcasting provides a forum for discussing the risks and benefits of nanotechnology.
- Peptide Nanostructure Kills Cancer Cells
By adding crown ether moieties to a polypeptide, chemists in Canada have created a nanoscale chemotherapeutic compound that can selectively and efficiently kill prostate cancer cells (Chem. Commun., DOI: 10.1039/b800528a).
- Nanocomposite Strategy Eliminates Matrix
The narrow spectral width and high quantum efficiency of lanthanide spectral emission make rare-earth-doped nanocrystals good candidates for optical materials.
- Toxic Socks
Silver nanoparticles intended to control odor release in the wash
- Silver socks have cloudy lining
A first assessment of socks containing silver nanoparticles, meant to cut down on foot odors, shows that the fabrics release most of the tiny particles in the wash—and possibly into the environment via solid waste from water treatment plants
