Palladium nanohexagons were prepared using a seed-mediated method. Their catalytic performance in 2-methyl-3-butyn-2-ol hydrogenation was compared to the one of monodispersed Pd nanospheres. Quantitative correlations between initial turnover frequencies (TOFs) and nanoparticle surface compositions showed independence of TOFs calculated per atoms on Pd(111) facets on particle size and shape.

Resonance dynamics of the magnetic moment a uniaxial ellipsoidal nanoparticle under its biasing along symmetry axis and excitation by transverse high-frequency field is studied with parameters (frequency, bias shape parameter), corresponding to noncollinear orientation equilibrium magnetization external static field. We revealed frequency regions where precession becomes nonlinear at weak alter...

Several challenges exist for successful nanoparticle cellular uptake—they must be able to cross many physical barriers reach their target and overcome the cell membrane. A strategy this challenge is exploit natural uptake mechanisms namely passive endocytic (i.e., clathrin- caveolin-dependent/-independent endocytosis, macropinocytosis phagocytosis). The influence of material size well documente...
