Scientists describe a new system to encase chemotherapy drugs within tiny, synthetic nanocarrier packages, which could be injected into patients and disassembled at the tumor site to release their toxic cargo.
It could be a crystal ball from a mythical age showing the swirling mists of time, but this image, which has won this year's Department of Engineering Photography Competition, actually shows graphene being processed in alcohol to produce conductive ink.
Researchers have developed a new strategy for fabricating more efficient plastic solar cells. The work has implications for developing solar cells with a wider absorption range and increased efficiency.
In contrast to biology, engineering seldom takes advantage of the power of randomness for fabricating complex structures. Now, a group scientists has demonstrated that randomness in molecular self-assembly can be combined with deterministic rules to produce complex nanostructures out of DNA.
Ever since scientists discovered that atomically thin materials could have useful electronic properties, engineers have been seeking ways to mass-produce so-called single-layer chips. A new technique shows how it might be done.
A combined theoretical and experimental approach has allowed researchers to predict and verify the full structure of a monolayer-coated molecular metal nanoparticle. The methodology was tested on silver-thiolate nanoparticles, expanding on earlier knowledge about gold nanoparticles, and is expected to be applicable to a broad range of sizes of nanoparticles made of different elements.
As well as being the thinnest, strongest and lightest known material, graphene is flexible, impermeable and extremely electrically and thermally conductive. All properties well suited for next generation NFC antennas.
Graphene holds the promise of such impressive applications as wear-resistant, friction-free coatings. But first manufacturers have to be able to produce large sheets of graphene under precisely controlled conditions.
