A monolithic array of three-dimensional microtraps is etched from a silica-on-silicon wafer and is characterized by confining and probing individual ions and strings of ions.
Nanotwinned copper nanopillars without any grain boundaries or other microstructural features are fabricated and used to explore the influence of twin boundaries on the mechanical properties of these structures.
High-speed atomic force microscopy and molecular simulations are used to form a probability map of the interactions and motions of a protein in a lipid membrane.
Replacing the semiconductor channel in a conventional field-effect transistor with a vacuum channel could lead to a new generation of low-power, high-speed devices.
Similar to certain enzymes, vanadium pentoxide nanowires show antibacterial activity and can prevent the colonization of marine microorganisms on surfaces such as ship hulls.
Small numbers of arsenic atoms are implanted into a silicon transistor, and the Anderson–Mott transition is observed by controlling the spacing between these dopants.
Using an approach that is analogous to Millikan's oil drop experiment, the size and charge of single nanoscale objects in solution can be directly measured by analysing their thermal motion in an array of electrostatic fluidic traps on a chip.
Iron oxide nanoparticles encapsulated inside a ferritin protein shell can be used to target and visualize tumours without the use of any targeting ligands or contrast agents.
Circularly polarized light has been used to confine charge carriers in single-layer molybdenum disulphide entirely to a single energy-band valley, representing full valley polarization.
Metal nanocubes grafted with polymers can self-assemble into arrays of one-dimensional strings that have well-defined interparticle orientations and tunable electromagnetic properties.
Lentil-shaped phospholipid vesicles are sensitive to shear stress, offering a new class of materials that can deliver drugs in response to rheological changes in the body.
