  This short review covers a wide selection of topics from a multidisciplinary
area of dynamics of nonequilibrium systems in physics, chemistry, biology.
Theoretical models of colloid particle and protein deposition and adhesion at
surfaces, accompanied by relaxation processes, of reaction kinetics with and
without diffusion, of phase coarsening and nucleation, will be surveyed. The
unifying feature of these systems is the importance of fluctuations and
many-body, multiparticle collective effects, in determining the dynamical
behavior which is typically nonclassical.
