Molecular mobility on graphene nanoroads. [PDF]
Sci Rep, 2015 AbstractWe study molecular mobility on a graphene nanoroad (GNRD), a pristine graphene strip embedded in between two hydrogenated graphene domains serving as a nanoscale pathway for transporting admolecules. Our molecular dynamics simulations using a prototype physisorbed C60 admolecule demonstrate that the proposed GNRD is able to confine the ...

Quantitative Analysis of Molecular Mobility in Amorphous Lactose Above Tg: A Novel Insight from Molecular Dynamic Simulation to Strength Parameter [PDF]
FoodsMeasuring molecular mobility (Mm) in solid food is challenging due to the rigid and heterogeneous nature of these matrices. The thermodynamic parameter Strength (S) fails to account for molecular displacement distances.

Glassy state molecular mobility and its relationship to the physico-mechanical properties of plasticized hydroxypropyl methylcellulose (HPMC) films [PDF]
International Journal of Pharmaceutics: X, 2019 Changes in tensile properties and the glass transition temperature (Tg) of plasticized polymer films are typically attributed to molecular mobility, often with no empirical data to support such an assertion.

A map of high-mobility molecular semiconductors [PDF]
Nature Materials, 2017 The charge mobility of molecular semiconductors is limited by the large fluctuation of intermolecular transfer integrals, often referred to as off-diagonal dynamic disorder, which causes transient localization of the carriers' eigenstates. Using a recently developed theoretical framework, we show here that the electronic structure of the molecular ...
