Percolation of single-walled carbon nanotubes in ceramic matrix nanocomposites [PDF]
, 2004 The percolation of carbon nanotubes (CNT) in an electrical insulating ceramic is studied for the first time. The in situ synthesis of the CNT (0.2–25 vol%) by a CCVD route allows to achieve their homogeneous distribution in the spinel matrix.

PERCOLATION TRANSITION AND TOPOLOGY
Image Analysis and Stereology, 2017 A number of bidimensional random structures with increasing densities are simulated to explore possible links between Euler-Poincaré characteristic (EPC), or connectivity, and percolation threshold.

Trapping thresholds in invasion percolation
Physical Review E, 2002 We give numerical estimates for the site percolation trapping thresholds for invasion percolation on various three dimensional lattices. We find that in most cases the thresholds for invasion and ordinary percolation coincide. However, for coordination numbers less than five the thresholds diverge.

Percolation and Epidemic Thresholds in Clustered Networks [PDF]
Physical Review Letters, 2006 We develop a theoretical approach to percolation in random clustered networks. We find that, although clustering in scale-free networks can strongly affect some percolation properties, such as the size and the resilience of the giant connected component, it cannot restore a finite percolation threshold.

Predicting percolation thresholds in networks [PDF]
Physical Review E, 2015 We consider different methods, that do not rely on numerical simulations of the percolation process, to approximate percolation thresholds in networks. We perform a systematic analysis on synthetic graphs and a collection of 109 real networks to quantify their effectiveness and reliability as prediction tools.

Percolation in the Boolean model with convex grains in high dimension
, 2023 International audienceWe investigate percolation in the Boolean model with convex grains in high dimension. For each dimension d, one fixes a compact, convex and symmetric set K ⊂ R d with non empty interior.

Hybrid Carbon Microfibers-Graphite Fillers for Piezoresistive Cementitious Composites
Sensors, 2021 Multifunctional structural materials are very promising in the field of engineering. Particularly, their strain sensing ability draws much attention for structural health monitoring applications. Generally, strain sensing materials are produced by adding
