Pyroresistive response of percolating conductive polymer composites
The pyroresistive response of conductive polymer composites (CPCs) has attracted much interest because of its potential applications in many electronic devices requiring a significant responsiveness to changes in external physical parameters such as temper ...
Amer Physical Soc2024A Tutorial-Cum-Survey on Percolation Theory With Applications in Large-Scale Wireless Networks
Connectivity is an important key performance indicator and a focal point of research in large-scale wireless networks. Due to path-loss attenuation of electromagnetic waves, direct wireless connectivity is limited to proximate devices. Nevertheless, connec ...
Ieee-Inst Electrical Electronics Engineers Inc2024THE PHASE TRANSITION FOR PLANAR GAUSSIAN PERCOLATION MODELS WITHOUT FKG
We develop techniques to study the phase transition for planar Gaussian percolation models that are not (necessarily) positively correlated. These models lack the property of positive associations (also known as the 'FKG inequality'), and hence many classi ...
Cleveland2023Percolation and phase behavior in cellulose nanocrystal suspensions from nonlinear rheological analysis
We examine the influence of surface charge on the percolation, gel-point and phase behavior of cellulose nanocrystal (CNC) suspensions in relation to their nonlinear rheological material response. Desulfation decreases CNC surface charge density which lead ...
ELSEVIER SCI LTD2023EXISTENCE OF AN UNBOUNDED NODAL HYPERSURFACE FOR SMOOTH GAUSSIAN FIELDS IN DIMENSION d >= 3
For the Bargmann-Fock field on R-d with d >= 3, we prove that the critical level l(c) (d) of the percolation model formed by the excursion sets {f >= l} is strictly positive. This implies that for every l sufficiently close to 0 (in particular for the noda ...
INST MATHEMATICAL STATISTICS-IMS2023Transparent Electrodes for Dielectric Elastomer Actuators
Mechanobiology is an emerging field that investigates the influence of mechanical forces on cell behavior and disease progression. Cells and tissues experience various mechanical stimuli in their natural environment, such as stretching and contracting, whi ...
2023Metastability of the Potts Ferromagnet on Random Regular Graphs
We study the performance of Markov chains for the q-state ferromagnetic Potts model on random regular graphs. While the cases of the grid and the complete graph are by now well-understood, the case of random regular graphs has resisted a detailed analysis ...
SPRINGER2023Controlling the Microstructure and Composition of 3D Printed Soft Load-Bearing Hydrogels
Hydrogels are among the first materials expressly designed for their use in biomedicine. However, state-of-the-art applications of hydrogels are severely limited because they are typically either too soft or too brittle such that they cannot bear significa ...
EPFL2023Geometric Percolation of Spherically Symmetric Fractal Aggregates
The connectedness percolation threshold (phi(c)) for spherically symmetric, randomly distributed fractal aggregates is investigated as a function of the fractal dimension (d(F)) of the aggregates through a mean-field approach. A pair of aggregates (each of ...
SPRINGER2022Recycling of Load-Bearing 3D Printable Double Network Granular Hydrogels
Esther Amstad, Matteo Hirsch, Alvaro Lino Boris Charlet, Sanjay Phileas Schreiber
Sustainable materials, such as recyclable polymers, become increasingly important as they are often environmentally friendlier than their one-time-use counterparts. In parallel, the trend toward more customized products demands for fast prototyping methods ...
