The monoclinic crystal polymorph of Y2O2SO4 has been demonstrated to have excellent structural compatibility with dopant rare-earth ions making it a promising material for upconversion (UC) applications. The UC emission intensity of calcined products was significantly enhanced when compared with the amorphous precursor, and the luminescent properties were also affected by the ratio and concentration of dopant rare-earth ions due to energy transfer and the symmetry of the crystal field.

Since mitochondrial superoxide dismutase (SOD2) is vital in maintaining intracellular levels of reactive oxygen species (ROS), a general strategy for killing cancer cells is reported by targeted inhibition of SOD2 using 2-methoxyestradiol (2-ME, an inhibitor for the SOD family) via an elaborately designed mitochondriatargeted mesoporous silica nanocarrier (mtMSN). The elevation of mitochondrial oxidative stress is demonstrated to be powerful in cancer therapy.

A general and facile high yield method for the synthesis of CoFe2O4, NiFe2O4 and CdFe2O4 hierarchical porous ball-in-ball hollow spheres has been developed. The as-obtained CoFe2O4 and NiFe2O4 show high reversible discharge capacity and good rate retention performance which make them promising materials for use as the anodes in lithium ion batteries.

Flexible multilayer MoS2 field effect transistors (FETs) enhanced by an ultra-short pulsed laser annealing process without any inflicted thermal damage are demonstrated. The reduced contact resistance after laser annealing provides significant improvements in transistor performance, including higher peak field-effect mobility, increased output resistance, increased self-gain, and decreased subthreshold swing.

TiO2 coated urchin-like SnO2 can suppress interfacial recombination of electrons, enhance dye loading capability and light scattering ability. Dye-sensitized solar cells (DSSCs) based on obtained materials show similar efficiency compared with pure TiO2 nanocrystalline photoanodes while only use ~55% amount of dye.
