Analysis of the development of drug products containing nanomaterials identifies several trends as well as the relative rate of approval of these products.
Optical waveguides patterned with gradient metasurfaces have compact footprints and broad wavelengths of operation thanks to tight control of the scattered light.
The demonstration of energy transfer from hotspots of electroluminescent silver nanoparticles to a two-dimensional crystal overlayer of a transition-metal dichalcogenide provides a tunable, sub-diffraction, electrically driven light source.
The transitional link from robust clearance of intravenously injected nanoparticles by strategically placed macrophages in systemic circulation to adverse haemodynamic reactions can be overcome by changing nanoparticle geometry or by prior nanoparticle attachment to erythrocytes
The electron gas confined onto a charged head-to-head domain wall in the ultrathin ferroelectric tunnel layer of a multiferroic tunnel junction drives the overall transport processes through the whole device.
Graphene nanoconstrictions achieved via mechanical exfoliation of highly oriented pyrolytic graphite evidence clear signatures of one-dimensional transport via zigzag edges.
Ion permeation and selectivity of graphene oxide membranes with sub-nm channels dramatically alters with the change in interlayer distance due to dehydration effects whereas permeation of water molecules remains largely unaffected.
Air-stable, non-encapsulated Bi2O2Se ultrathin films grown by chemical vapour deposition display high electron mobility and exceptional semiconducting transport properties, making the observation of quantum oscillations possible and suggesting potential applications in electronics.
High-speed absorption of vicious crude oil spill into oil sorbent was realized by introducing the Joule heating effect of graphene to the interface between the skeleton surfaces of sorbent and oil.
In situ characterization of the full reaction pathways of a solid state LiO2 battery shows the formation of hollow nanostructures as a result of the interplay between lithium ion diffusion, electron transport and oxygen gas evolution at the cathode.
A set of independently light-controlled motor and modulator subunits embedded in a polymer gel matrix enables controlled macroscopic expansion and retraction of the material.
