    Pickering emulsions, stabilized by particles, have attracted much attention in recent years. Due to the introduction of particles at the interface between oil and aqueous phases, Pickering emulsions possess many distinctive properties such as high stability and low toxicity, when compared with classical emulsions stabilized by surfactants. These properties also affect their applications, especially in biomedical fields, such as oral or topical delivery systems.

  3. Seeded Synthesis of Monodisperse Core–Shell and Hollow Carbon Spheres

    Monodisperse carbon spheres between 500 and 900 nm are hydrothermally synthesized from glucose on polystyrene seeds. Control over temperature, time, glucose concentration, and seed size yields hybrid spheres without aggregation and no additional spheres population. Pyrolysis transforms the hybrid into hollow carbon spheres preserving monodispersity. This approach provides a basis for functional carbon spheres applicable in photonics and energy storage.

  4. Shape-Enhanced Photocatalytic Activities of Thoroughly Mesoporous ZnO Nanofibers

    Thoroughly mesoporous ZnO nanofibers with tailored cross-sectional morphologies, i.e., circle, ellipse, and rectangle, are produced via a facile foaming-assisted electrospinning strategy. Fibers with elliptical cross-sections exhibit significantly shape-enhanced photocatalytic activities induced by their unblocked stacking mode. The experimental discovery and complimentary analysis suggest that the fibers should possess elliptical cross-section in order to achieve the optimal photocatalytic performance.

    Nonstoichiometric Na0.52YbF3.52:Er nanoprobes are synthesized via a facile solvothermal method, showing selectively increased red upconversion luminescence because of successful local structure engineering. By virtue of the high luminescence property of these nanoprobes under 915 nm light excitation, efficient photodynamic therapy of tumors with limited overheating is achieved. Moreover, high contrast MR and CT bioimaging are also realized based on this multifunctional material, indicating their great potential as multiplex theranostic nanoplatforms.
