Abstract A percolation model with nucleation and object growth is studied by Monte Carlo simulations on a triangular lattice finite-size impurities. The growing objects are needle-like self-avoiding random walk chains. Results obtained for three different shapes of impurities covering sites—needle-like, angled triangular. In each run through the system, initially randomly occupied specified shape at given concentration <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"...

Percolation properties of two-component mixtures are studied by Monte Carlo simulations. Objects deposited onto a substrate according to the random sequential adsorption model. Various shapes making made self-avoiding walks on triangular lattice. threshold for objects covering same number sites is always lower than more compact object, and it can be even both components. Mixtures percolating non-percolating almost percolate, but percolation higher component. Adding shape high connectivity...

&amp;lt;p&amp;gt;Metallic materials in granular packings show different electrical properties from their bulk counterparts. In this paper, we investigate the temporal evolution of conductivity metals. We use metallic beads arranged one-, two- and three-dimensional ensembles through which constant currents are injected. The behavior all three types systems is qualitatively similar. results rise more pronounced earlier stages time evolution. influence dimensionality, number beads, values...

Abstract Random sequential adsorption (RSA) is a broadly used model for irreversible deposition on substrates. Over the last decades, huge number of works have been published concerning this topic.

In this paper we investigate the temporal evolution of electrical resistance through different two-dimensional (2D) packings Ni beads when 1 mA current is injected in them. first stages measurements, decreases towards a saturation value and it can be fitted with Mittag-Leffler function. Fitting parameters show that relaxation dynamics does not depend on type packing. Different differences initial values which attributed to formation new microcontacts during Pauses flow cause either decrease,...

Abstract The resistance drop with time in metallic granular materials has been the subject of research since 19th century, but it is still not fully clarified. wider application industry contributed to increased interest this phenomenon. key parameters that are mainly examined as follows: influence different packings, dimensions, and shapes granules, well pressure, exerted on them. However, there a limited number papers examine temporal evolution these materials. In report, we investigate...

The physical and chemical properties of the nanocrystals are highly shape dependent, control has become very important. seeded growth method enables seeds to grow in a predetermined way. We have already proposed such amodel that can reproduce granular on triangular lattice for different shapes. In this paper, however, we introduced limitation seed up certain length. This be used when all limited same length, or mixture with limits.The main goal is investigate how growing limits affect values...
