Cheap and Efficient Solar Cells with PbSe Quantum Dot Photovoltaics

For solar cells to be useful, they need to be cheap, cover a large area, and be physically flexible, which are benefits of using solution-processed photovoltaics. Much of the current research in solution-processed photov...

Research Shows the Movement of Nanoparticles Through a 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. The preliminary results observed by researchers from the National Institute of Standards and Technology (NIST) suggest that the particular nanomaterials studied may not accumulate in invertebrate food chains

Advances in Data Storage and Quantum Computing to Come From Simulation That Shows How Graphene Can Form Iridium Muffins

Graphene flakes are notoriously difficult to work with. Still, they are stronger than diamond, better heat-shedders and conductors than silicon, and thought to have great potential in the worlds of microelectronics and sensors. If only they could be tamed.

Using Nanotechnology and Nanoparticle Based Imaging to Produce Whole Body Images Showing Cancer Tumor Locations

Researchers have published a paper that describes a strategy for
small-animal optical imaging based on Raman spectroscopy and
Raman nanoparticles. Surface-enhanced Raman scattering nanoparticles
and single-wall carbon nanotubes were used to demonstrate
whole-body Raman imaging, nanoparticle pharmacokinetics,
multiplexing, and in vivo tumor targeting, using an imaging
system adapted for small-animal Raman imaging.
