Structural criterion for the onset of rigidity in a colloidal gel
C. S. Dias, J. C. Neves, M. M. Telo da Gama +2
Identifying the necessary conditions for the onset of rigidity in a gel remains a challenge. It has been suggested that local particle coordination could be used to establish such…
Optimal Number of Faces for Fast Self-Folding Kirigami
H. P. M. Melo, C. S. Dias, N. A. M. Araujo
We study the spontaneous folding of a 2D template of microscopic panels into a 3D pyramid, driven by thermal fluctuations. Combining numerical simulations and analytical calculatio…
Mechanical equilibrium of aggregates of dielectric spheres
A. F. V. Matias, T. Shinbrot, N. A. M. Araujo
Industrial as well as natural aggregation of fine particles is believed to be associated with electrostatics. Yet like charges repel, so it is unclear how similarly treated particl…
Dynamics of a network fluid within the liquid-gas coexistence region
C. S. Dias, J. M. Tavares, N. A. M. Araujo +1
Low-density networks of molecules or colloids are formed at low temperatures when the interparticle interactions are valence limited. Prototypical examples are networks of patchy p…
