Polymer Molecular Weight from Loss Modulus
Polymer Journal, 1992The method for the determination of polymer molecular weight and molecular weight distribution from transient and dynamic viscoelastic properties of a narrow molecular weight distribution linear amorphous polymer with Mw>Mc has been discussed in our previous work.

Predictive Models for Storage Modulus and Loss Modulus of Asphalt Mixtures
Journal of Materials in Civil Engineering, 2016AbstractComplex modulus of an asphalt mixture constitutes two components: E′ representing the ability of the mixture to store energy (elastic behavior), and E′′ reflecting the capacity of the material to dissipate energy (viscous behavior). The main objective of this study was to develop predictive equations for the two components, E′ and E′′, to ...

ABSTRACT The storage modulus and loss modulus of blends of polypropylene/polystyrene and polyethylene/polystyrene have been mapped quantitatively with contact resonance atomic force microscopy. Contact resonance spectra were collected in Dual AC Resonance Tracking (DART) mode, in which the phase and amplitude are monitored at two discrete ...

Substrate loss modulus promotes the differentiation of SHSY-5Y neuroblastoma cells
Materialia, 2021Abstract Moduli of the extracellular matrix influence multiple cellular functions such as proliferation, migration, senescence, and differentiation. However, the in vitro studies predominantly consider the Young's (or elastic) modulus of the substrate, and the independent role of its loss (or viscous) modulus, is often not acknowledged. In this work,

Abstract Dynamic mechanical analysis (DMA) method is used to measure viscoelastic properties such as storage and loss moduli of materials. The present work is focused on developing a generalized model that allows transforming the storage and loss moduli obtained from DMA to time domain elastic modulus values.
