Self-assembled nanostructured cathodes allow lithium-ion and nickel-metal hydride batteries to charge and discharge at very high rates without significant loss of capacity.
Insulating thin films with a random structure can undergo a nanoscale metal–insulator transition by making the film thickness size less than or more than the electron diffusion distance.
Nitrogen-vacancy-centre spin coherence can be used to detect two or more distant nuclear spins if they are strongly bonded to each other and to measure nuclear magnetic resonances of single molecules.
Hybrid structures made of nanoporous gold and nanocrystalline manganese dioxide offer high specific capacitances and high charge–discharge rates, which makes them promising candidates for the electrode materials in electrochemical supercapacitors.
Coating the walls of synthetic nanopores with fluid lipids slows down the translocation of proteins, eliminates non-specific binding and prevents clogging, thus offering a way to improve the performance of nanopore-based sensors.
Approaches in quantitative structure–activity relationships developed to predict the physical and chemical properties of chemical compounds can also be used to predict the toxicity of nanoparticles.
The contact resistance of a junction between graphene and palladium is shown to be strongly affected by carrier transport in graphene underneath the palladium, and is measured to be just two to three times larger than the minimum resistance achievable.
Calculations show that two-dimensional conductance spectra in a graphene nanoribbon placed across a fluidic nanochannel can be used to rapidly and reliably sequence DNA.
Carbon nanotube transistors with high mobilities and high on/off ratios are demonstrated, along with flexible nanotube-based integrated circuits that are capable of sequential logic.
Real-time atomic force microscopy can be used image the individual steps of a DNA motor as it moves, autonomously and at constant average speed, along a 100-nm track.
Pretreating rats with amine-modified single-walled carbon nanotubes can decrease brain injury and enhance recovery of behavioural functions after a stroke.
The uptake of nanoparticles into cells and their inheritance during cell division is shown to be random, which has implications for dose considerations in drug delivery and nanotoxicology studies.
