From Double Colloidal Networks to Core-Shell and Mixed Composites through Sequential Gelation
Alexander Kaltashov, Safa Jamali
Multicomponent gel systems have garnered much interest due to their compelling mechanical properties in the past decade. Yet, some mechanisms associated with multicomponent gels, s…
Brush-mediated angular constraints reshape structure, rigidity, and percolation in colloidal depletion gels
Ziye Zhuang, Robert A. Campbell, Paniz Haghighi +2
Colloidal gels, like many other soft and disordered solids derive their mechanical properties not only from the strength of interparticle attraction, but also from the symmetry of…
Non-local physics-informed neural networks for forward and inverse solutions of granular flows
Saghar Zolfaghari, Safa Jamali
Dense granular flows exhibit nonlocal effects due to stress transmission in microplastic events, especially in quasi-static or slowly sheared regions. Hence, traditional local rheo…
A Minimal Nonlocal Theory of Thixotropic Flow
Saghar Zolfaghari, Safa Jamali
Dense amorphous materials exhibit both nonlocal flow cooperativity and pronounced history dependence, yet existing continuum models capture only one of these features at a time. No…
