WebJan 9, 2024 · The diffusional broadening of B was analyzed by means of secondary ion mass spectrometry (SIMS) and numerically described to determine the diffusion coefficient. Additional SIMS analyses revealed a gradient in the oxygen (O) background concentration of the epitaxially doped Ge structure. A high O content observed in near-surface regions ... WebMay 1, 2003 · Diffusional broadening, which has been examined thoroughly by Stolzenburg (1988), is naturally dependent on particle size. Instrumental broadening refers to the geometrical design of the DMA, to the presence of a non-ideal flow field, and to other DMA imperfections which are all constant for given aerosol and sheath air flow rates and …
WebThe dynamics of bulk liquid para-cresol from 340–390 K was probed using a tandem quasielastic neutron scattering (QENS) and molecular dynamics (MD) approach, due to its relevance as a simple model component of lignin pyrolysis oil. QENS experiments observed both translational jump diffusion and isotropic rotation, with diffusion coefficients ranging …
