A multifunctional mesoporous bioactive glass (MBG)/upconversion nanoparticle (UCNP) nanocomposite based on UCNPs@SiO2@mSiO2- 15Ca with the ability to deliver anti-cancer drugs, monitor drug release, and stimulate osteogenic differentiation of bone marrow stromal cells was prepared using a layer-by-layer method. Owing to its multifunctional properties, the prepared MBG/UCNP nanocomposite has potential application as a bone-repair material for the treatment of bone defects caused by malignant bone tumor surgery.

Elemental Pd was successfully dispersed into a CuS nanoplate substrate by making use of a concomitantly formed amorphous structure through cation exchange. By screening a series of Pddispersed CuS hetero-nanoplates with tailored proportions and compositions, the optimal catalytic performance towards semihydrogenation of phenylacetylene with good selectivity, activity, and stability was achieved.
