2021 APS March Meeting

Get updates about our research at the 2021 APS March Meeting.

At the meeting, Abhay Goyal will talk about the ion-specificity of nanoscale forces in ionic solutions confined between charged surfaces, that he elucidated through numerical simulations with explicit water. He will discuss the implications for materials like cement and clays. Minaspi Bantawa will give a talk in the session on gel rheology about his work on the linear viscoelasticity of soft particulate gels. He will discuss how we could identify a fractal characteristics in the viscoelastic spectrum of model colloidal gels and trace it back to the rigid backbone of the incipient gel in the beginning of the gelation process. He will also discuss microscopic timescales and their connection to the constitutive behavior of the gel.

Emanuela’s talk will be about the nanoscale physical origin of cement cohesion and how that enters the understanding of growth and morphology of cement hydrate gels, in an interdisciplinary session that is devoted to biomineralization phenomena and complex material solidification from soft precursors.
