Current Distribution Characteristics of Parallel Carbon Brushes

Parallel cleaning of a network with brushes

We consider the process of cleaning a network where at each time step, all vertices that have at least as many brushes as incident, contaminated edges, send brushes down these edges and remove them from the network. An added condition is that, because of the contamination model used, the final configuration must be the initial configuration of another cleaning of the network. We find the minimu...

The Effect of the Elastic Modulus and Solid Viscosity of Carbon Brushes on their Commutation Characteristics

We have tried a theoretical study upon the experimental results obtained by the preceeding method. In other words, we considered that the brush is a vibration system of the combination of elastic body and shock absorver and gat its approximate solution by method of concentrated mass. From the above study we arrived at the conclusion that the improvement of contacting condition of the brush depe...

Current-voltage characteristics of carbon nanotubes with substitutional nitrogen

Deformation and capillary self-repair of carbon nanotube brushes

Brushes with nanoscale bristles, such as nanotube arrays held together by van der Waals forces, have applications as compliant electrical switches, probes and micro-scale cleaning tools. Repeated use exposes the brushes to contact and impact at high strains resulting in the bristles undergoing exfoliation, deformation and damage. We show that the damages incurred can be nearly recovered by capi...
