      Solvent-vapor annealing has been successfully employed to increase the degree of order in the self-organization of a perylene-bis(dicarboximide) derivative cast on different substrates from solution (see figure). Upon exposure to tetrahydrofuran vapors, the starting needle-like structures rearrange into millimeter-long fibers, which have a sub-micrometer cross section, with remarkable mass transport at the surface.

      The in vivo cellular uptake, degradation and biocompatibility of polyelectrolyte microcapsules produced from alternating dextran sulphate and poly-L-arginine layers on a template of calcium carbonate microparticles is reported. A moderate tissue reaction is observed after subcutaneous injection of polyelectrolyte microcapsules in mice. Within sixteen days after subcutaneous injection, most of the microcapsules are internalized by the cells and start to degrade. The number of polyelectrolyte layers determines the stability of the microcapsules after cellular uptake.

      Thumbnail image of graphical abstract

      The magnetic and transport properties of homogeneously strained high quality LCMO/STO thin films are analyzed. Soft X-ray absorption spectroscopy at the O K-edge shows that interfacial strain due to substrate/film mismatch is strong enough to split the eg and t2g levels close to the film/substrate interface, promoting selective orbital occupancy with charge localization, favoring the appearance of an orbital glass insulating phase. Concomitantly, we observe an increase of the Mn4+ concentration close to this interface.

      A novel 3D cement direct printing process is established to manufacture a variety of calcium phosphate bone graft substitutes with programmed macropore architecture at room temperature (see figure). Here we compare the in vivo dissolution of CaHPO4·2H20, brushite, with that of the anhydrous form monetite for the first time. Monetite was found to be approximately twice more soluble in vivo and, unlike brushite, did not convert to insoluble HA.

      A microwave-induced method for controlled purification of single-walled carbon nanotubes by removing residual metal catalysts and non-tubular carbonaceous matter is presented. The method employs weak acids and chelating agents to remove these impurities. Consequently, there is no detectable damage or functionalization of the nanotube sidewalls.
