    Nonspherical ellipsoidal nanodimensional artificial antigen-presenting cells (aAPCs) are fabricated by J. J. Green and co-workers and on page 1519 they are shown to have superior T-Cell activation and pharmacokinetic properties compared to equivalent spherical nanodimensional aAPCs. Shown on the cover are transmission electron microscopy images of the ellipsoidal nanoparticles interacting with a computer generated T-Cell membrane as nano aAPCs. Due to their larger radius of curvature, ellipsoidal nano aAPCs are more effective at biomimicry of natural APCs for antigen-specific T-Cell activation.

    Nanocrystals of CdTe with a zinc blende structure are described by D. J. Binks and co-workers. The surface of each is passivated by a combination of oleylamine ligands and a varying number of chloride ions, shown in the cover image as yellow spheres, that result from the treatment described on page 1548, and which results in near-unity photoluminesence quantum yields.

    ZnS composites wrapped in reduced graphene oxide (rGO), are used to generate nanoframes (NFs) which exhibit an excellent photocurrent response. On page 1512, L. M. Liu, J. Luo, J. Zhu, and co-workers describe how the NF growth is realized in situ on rGO by confining the evolution of ZnS nanoparticles from nanosheets and the nanoparticle assembly within quasi-2D spaces generated from graphene oxide (GO) that is reduced to rGO. In the image, the curved light path connects the various states of nanoframe evolution.
