Scientists have overcome key design hurdles to expand the potential uses of nanopores and nanotubes. The creation of smart nanotubes with selective mass transport opens up a wider range of applications for water purification, chemical separation and fighting disease.
The IEEE Photonics Society's 2012 International Group IV Photonics Conference is a single-track conference that will feature presentations focused on silicon photonics integration, applications and manufacturing technology; photonic devices and nanostructures; as well as advanced materials and fabrication technologies.
Johns Hopkins tissue engineers have used tiny, artificial fiber scaffolds thousands of times smaller than a human hair to help coax stem cells into developing into cartilage, the shock-absorbing lining of elbows and knees that often wears thin from injury or age.
Drexel University engineers continue to drive research into the use of carbon nanotubes, straw-like structures that are more than 1,000 times thinner than a single human hair. Their most recent development uses the tiny tubes to separate liquids within a solution.
The sun breaks through the clouds - and surfaces start cleaning themselves! It may sound like magic, but in fact it's all thanks to the addition of titanium dioxide molecules. Activated by UV light, they trigger a reaction which destroys bacteria, algae and fungi, keeping items such as the armrests of garden chairs nice and clean.
Chemists and materials scientists from the University of Groningen and the FOM Foundation have found a way of 'harvesting' infrared light more efficiently. For this they use special molecules, which act as light antennae to capture the energy from weak infrared light.
A network of porous carbon tubes that is three-dimensionally interwoven at nano and micro level - this is the lightest material in the world. It weights only 0.2 milligrams per cubic centimetre, and is therefore 75 times lighter than Styrofoam, but it is very strong nevertheless.
Ein Netzwerk aus porösen Kohlenstoffröhrchen, die dreidimensional auf Nano- und Mikroebene ineinander verwachsen sind - das ist das leichteste Material der Welt. Mit 0,2 Milligramm pro Kubikzentimeter ist es 75-mal leichter als Styropor und hält trotzdem eine Menge aus.
