    Graphene oxide–bacterial cellulose (GO/BC) nanocomposite hydrogels with well-dispersed GO in the network of BC have been successfully developed using a facile one-step in situ biosynthesis by adding GO suspension into the culture medium of BC. The composites show a significant increase in tensile properties at relatively low GO loadings.

  2. Strategy for Good Dispersion of Well-Defined Tetrapods in Semiconducting Polymer Matrices

    The results presented here demonstrate that rigid tetrapod-like structures are not compatible with a melt of flexible polymer chains. Compatibility can, however, be achieved by grafting well-designed polymers onto them. Thus, it is possible to prepare homogeneous dispersions of tetrapods with arm lengths up to 100 nm in a polymer matrix. With respect to polymer electronics, this allows the preparation of new semiconducting polymer–CdSe TP hybrid systems with well-dispersed morphology.

  3. Metallo-Supramolecular Nanogels for Intracellular pH-Responsive Drug Release

    Intracellular pH-responsive metallo-supramolecular nanogels (MSNs) with excellent biocompatibility and stability are fabricated by the metallo-supramolecular-coordinated interaction between histidine and iron-meso-tetraphenylporphin. MSNs show excellent pH responsiveness in the intracellular mildly acidic environment, which has great potential for acid-triggered drug release delivery.

    Back Cover: This study, for the first time, demonstrates that the solvent vapor annealing (SVA) method can be utilized to introduce structural hierarchy to PCL-based fibers. The acetone vapor can delocalize amorphous chains and redeposit them onto the existing crystal edges, leading to hierarchically structured fibers. This facile approach provides new insight into the design and fabrication of hierarchical polymeric materials. Further details can be found in the article by J. Liu, A. J. P. Bauer, and B. Li* on page 1503.
