Summary: A programmable shear-induced dynamic assembly approach was developed to synthesize mesoporous carbon nanospheres with tunable core-shell structures and gradient pore systems. The micelle structures in the system can be adjusted by changing shear force and a programmatically proceeded synthesis process results in intelligent assembly of multimodal mesostructures. The resultant carbon nanospheres exhibit high capacity and ultra-long cyclic life for sodium-ion storage, showing potential for innovative applications.

Summary: By preparing mesoporous shell/core silica abrasives and developing a novel green CMP slurry, polishing performance can be improved and environmental pollution can be reduced. Molecular dynamics simulations show that the mesoporous structure inhibits the formation of convex peaks and promotes uniform distribution and removal of surface atoms, leading to enhanced polishing results.

Summary: Magnetic CuFe2O4 nanoparticles were synthesized via a sol-gel combustion and coated with mesoporous SiO2. The CuFe2O4@SiO2 nanocomposite showed high ibuprofen loading and controlled drug release, with potential applications in biomedicine. Coating CuFe2O4 nanoparticles with mesoporous silica reduced cytotoxicity and improved drug release properties, although it decreased hyperthermia ability.

Summary: In this study, a redox-responsive nanocarrier (RGD-MSNs@BSA) was developed by conjugating bovine serum albumin (BSA) to mesoporous silica nanoparticles (MSNs) with a disulfide bond, which showed efficient and stable encapsulation of the anticancer drug doxorubicin (DOX) and redox-responsive drug release in a glutathione (GSH)-containing environment. Moreover, the modification of cRGD peptide on the particle surface enhanced the tumor cell-targeting and cellular uptake of the nanoparticles.

Summary: A bifunctional core-shell catalyst consisting of Ni nanoparticles encapsulated by an Al-doped mesoporous silica shell was reported, which achieved 100% conversion of vanillin and >99% yield of 2-methoxy-4-methylphenol. The catalytic activity remained stable after 10 recycles due to the unique mesoporous core-shell structure. Incorporating Al atoms into the silica shell significantly increased the number of acidic sites. This work provides an efficient bifunctional hydrodeoxygenation catalyst and a new synthetic protocol for designing non-noble metal catalysts.
