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…
Collective transport of droplets through porous media
Rodrigo C. V. Coelho, Danilo P. F. Silva, António M. R. Maschio +2
The flow of deformable particles, such as droplets, dragged by a fluid, through a network of narrow pores inside rocks or other porous media is key in a range of applications, from…
Study of fluid displacement in 3D porous media with an improved multi-component pseudopotential lattice Boltzmann method
M. Sedahmed, R. C. V. Coelho, N. A. M. Araújo +2
We generalize to three dimensions (3D) a recently developed improved multi-component pseudopotential lattice Boltzmann method and analyze its applicability to simulate flows throug…
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…
The symbiotic contact process: phase transitions, hysteresis cycles, and bistability
C. I. N. Sampaio Filho, T. B. dos Santos, N. A. M. Araújo +3
We performed Monte Carlo simulations of the symbiotic contact process on different spatial dimensions (). On the complete and random graphs (infinite dimension), we observe hyst…
Finding the optimal nets for self-folding Kirigami
N. A. M. Araújo, R. A. da Costa, S. N. Dorogovtsev +1
Three-dimensional shells can be synthesized from the spontaneous self-folding of two-dimensional templates of interconnected panels, called nets. However, some nets are more likely…
Percolation study for the capillary ascent of a liquid through a granular soil
M. A. Cárdenas-Barrantes, J. D. Muñoz, N. A. M. Araujo
Capillary rise plays a crucial role in the construction of road embankments in flood zones, where hydrophobic compounds are added to the soil to suppress the rising of water and av…
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…
Critical fragmentation properties of random drilling: How many random holes need to be drilled to collapse a wooden cube?
K. J. Schrenk, M. R. Hilário, V. Sidoravicius +4
A solid wooden cube fragments into pieces as we sequentially drill holes through it randomly. This seemingly straightforward observation encompasses deep and nontrivial geometrical…
Usage leading to an abrupt collapse of connectivity
D. V. Stäger, N. A. M. Araújo, H. J. Herrmann
Network infrastructures are essential for the distribution of resources such as electricity and water. Typical strategies to assess their resilience focus on the impact of a sequen…
