Three-dimensional (3D) macroporous CuO structures composed of ultrathin nanosheets were successfully synthesized by employing a liquid-liquid interface as a two-dimensional (2D) nano-reactor. The macroporous structure helped CuO to retain the exposed surface during reactions, thus significantly enhancing the long term cycling performance both in photocatalysis and lithium ion batteries.

Zn1−xMgxSe alloys have been grown on (100) GaAs substrates by molecular beam epitaxy. Their crystal structures are determined form x-ray diffraction spectra and are found to be zinc blende, rocksalt, and their mixture for x<0.5, x=1, and x∼0.6, respectively. The Raman spectra are measured and show two-mode behavior for those alloys with zinc blende structure. The long-wavelength frequencies of ZnSe- and MgSe-like optical phonons are determined and the results can be expressed as linear functions of x. The first-order Raman spectra are observed for MgSe and Mg-rich Zn1−xMgxSe alloys with rocksalt structure. Those Raman spectra are attributed to the scattering from optical phonons activated by disorders and impurities, and their line shapes represent the phonon density of states.

We have developed one versatile spatially confined self-assembly strategy to integrate cyanometallate-based coordination polymers with functional metal oxides into well-defined core@shell heterostructures. The structure, composition, size and morphology of the heterostructures could be facilely controlled. The obtained Fe3O4@Prussian blue heterostructure was evaluated as an appealing multifunctional thermal ablation agent exhibiting response to both magnetic field and light irradiation.
