Introduction Developmental dysplasia of the hip (DDH) is characterized by abnormal acetabular and femoral anatomy.1 This anatomical anomaly leads to increased stress on the hip joint, causing it to be in a non-physiological wear state for an extended period.

MOF-derived metal oxide composite Mn2Co1Ox/CN for efficient formaldehyde oxidation at low temperature Metal oxide and metal oxide composites have drew substantial consideration owing to the possibility as a substitute for noble metal catalysts for HCHO oxidation, but there still remain challenges when developing the structures and morphologies to maximize their catalytic performance.

With an improved one-step reverse micelle method, Pd@SiO -RM with thermally stable, 1.1 nm ultra-small Pd nanoparticles were prepared in one-pot. HRTEM results reveal that the ultra-small Pd nanoparticles are embedded in the bulk of the silica nanospheres around 30 nm to form a multi-core shell structure. Therefore, the migration and agglomeration of the ultra-small Pd nanoparticle cores can be impeded effectively at elevated temperatures.
