Web2 dagen geleden · The 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 … WebAB - The QUASES-IMFP-TPP2M-CF software is a user friendly calculator for the inelastic electron mean free path for electrons in materials. It is based on the Tanuma, Powell and Penn algorithm [1,2].The software includes a database with parameter values for all elements and a wide range of compounds, oxides, and polymers. Following, the IMFP is employed to calculate the effective attenuation length (EAL), the mean escape depth (MED) and the information depth (ID). Besides, one can utilize the IMFP to make matrix corrections for the relative sensitivity factor in quantitative surface analysis. Moreover, the IMFP is an important parameter in Monte Carlo simulations of photoelectron transport in matter. restore macbook pro before selling
