  text: In this work, a new model for the simulation of nanostructured aggregates
    by simultaneous coagulation, sintering and surface growth is presented. Coagulation
    is treated as cluster–cluster agglomeration along the line connecting the center
    of mass of both agglomerates and is implemented using a Monte Carlo algorithm.
    Sintering is modeled as successive overlapping of spheres which cause reduction
    in the surface area based on a rate law for surface reduction. Surface growth
    is modeled as an increase in primary particle diameter, e.g. as a result of surface
    reactions. The evolved aggregates are analyzed by calculating their fractal dimension,
    radius of gyration, mobility diameter and mobility shape factor. It is found that
    the aggregates structure tends to be more compact when introducing the surface
    growth in shorter time comparing to the coagulation-sintering step only. Fractal
    dimension and the mobility shape factor of the resulting aggregates are correlated
    to an effective dimensionless time that combines the characteristic times of these
    three fundamental mechanisms. It is shown that the mobility diameter in the free
    molecular regime is not proportional to the radius of gyration. A power law relation
    that correlates the aggregates projected area and the equivalent number of primary
    particles is found to be in a very good agreement with estimates published in
    literature.
