“…We consider the case of i = 1, 2, …, N electrically conducting spheres of radius R . Since the current has been experimentally measured to be quite low 21 , the conductor interactions can be modeled using electrostatics alone. In the empty regions between conductors, the electric potential is determined by the Laplace equation…”

Interacting electrical conductors self-assemble to form tree like networks in the presence of applied voltages or currents. Experiments have shown that the degree distribution of the steady state networks are identical over a wide range of network sizes. In this work we develop a new model of the self-assembly process starting from the underlying physical interaction between conductors. In agreement with experimental results we find that for steady state networks, our model predicts that the fraction of endpoints is a constant of 0.252, and the fraction of branch points is 0.237. We find that our model predicts that these scaling properties also hold for the network during the approach to the steady state as well. In addition, we also reproduce the experimental distribution of nodes with a given Strahler number for all steady state networks studied.

Nanoparticles have actually been in our lives for many years and begun to possess inevitable place in the life cycle with the gradual development of nanotechnology. Recent studies and improvement indicate that the use of nanoparticles will be expected to increase in many areas such as biology, medicine, engineering and optics in the future. In this review, nanoparticles, their applications, damage and damage prevention methods are discussed.

“…The fabrication of one-dimensional (1D) colloidal and granular materials is presently a very active area of nano- and micromaterials research. Colloidal and granular 1D assemblies offer great opportunities for both fundamental studies [ 1 , 2 , 3 ] and practical applications, including applications in optoelectronics [ 4 ], photonics [ 5 ], sensors [ 6 ], photovoltaics [ 7 ], and flexible electronics [ 8 ]. The 1D assemblies can be composed of either particle groups [ 9 , 10 , 11 ] or individual particles forming particle chain-like structures [ 12 , 13 , 14 ].…”

Being able to systematically modify the electric properties of nano- and microparticles opens up new possibilities for the bottom-up fabrication of advanced materials such as the fabrication of one-dimensional (1D) colloidal and granular materials. Fabricating 1D structures from individual particles offers plenty of applications ranging from electronic sensors and photovoltaics to artificial flagella for hydrodynamic propulsion. In this work, we demonstrate the assembly of 1D structures composed of individual microparticles with modified electric properties, pulled out of a liquid environment into air. Polystyrene particles were modified by sulfonation for different reaction times and characterized by dielectric spectroscopy and dipolar force measurements. We found that by increasing the sulfonation time, the values of both electrical conductivity and dielectric constant of the particles increase, and that the relaxation frequency of particle electric polarization changes, causing the measured dielectric loss of the particles to shift towards higher frequencies. We attributed these results to water adsorbed at the surface of the particles. With sulfonated polystyrene particles exhibiting a range of electric properties, we showed how the electric properties of individual particles influence the formation of 1D structures. By tuning applied voltage and frequency, we were able to control the formation and dynamics of 1D structures, including chain bending and oscillation.
