DOI: 10.1021/acsmacrolett.4c00438

Abstract: This study examines nanoparticle diffusion in crowded polymer nanocomposites by diffusing small Al2O3 nanoparticles (NPs) in SiO2-loaded P2VP matrices. Time-of-flight secondary ion mass spectroscopy (ToF-SIMS) measures Al2O3 NP diffusion coefficients within a homogeneous PNC background… read more here.

DOI: 10.1063/5.0258037

Abstract: The self-assembly patterns formed during the drying of nanofluid films and droplets are closely associated with the diffusion dynamics of nanoparticles driven by evaporation. This study employs a quasi-three-dimensional kinetic Monte Carlo model to simulate… read more here.

DOI: 10.1557/s43579-024-00596-7

Abstract: Nanoparticle diffusion is a fundamental process that ubiquitously exists in life science and engineering technology. Recent studies demonstrate the potential of harnessing mechanical deformation to program nanoparticle diffusion in hydrogels, offering an expanded spectrum of… read more here.
