    Surface potential engineering for in-memory computing

    The cover image represents a distribution of nonvolatile memory charge arrays on a potential energy surface landscape. Memory arrays based on surface potential engineering can execute nonlinear activation during the computing process, resulting in low power consumption.

    Mathematics at the speed of light

    The cover image depicts the continuous reflection of a light signal between a semi-transparent mirror and a nanostructured dielectric substrate. The optimized shape of the dielectric unit cell implements a matrix multiplication to the signal corresponding to the mathematical problem of interest.

    From DNA slats to cell-sized rugs

    The microscopy image shows a multi-micron DNA structure obtained from crisscross polymerization of thousands of uniquely addressable DNA-origami ‘slats’.

    Ion–water clusters in carbon nanotubes

    The cover image depicts an isolated ion–water cluster inside a carbon nanotube. Such clusters are responsible for the unusually fast electrophoretic transport of potassium ions and lead to a strong breakdown of the Nernst–Einstein relation.

    Shaking off the heat

    The cover shows two trapped nanoparticles whose motion has been simultaneously cooled through a technique that uses precise shaking of laser beams.
