In this paper, we use the coincidence degreetheory to establish new results on the existence and uniqueness ofT-periodic solutions for a kind of Rayleighequation with a deviating argument of the formx''+f(x'(t))+g(t,x(t-tau(t)))=p(t).

In this paper, we use the coincidence degree theory to establish new results on the existence and uniqueness of T-periodic solutions for a kind of Rayleigh equation with a deviating argument of the form $x'+f(x'(t))+g(t,\;x(t-\tau(t)))=p(t)$.

The composite of carbon nanotubes/graphene networks loaded-Ni (CNTs/GR-Ni) were suc-cessfully synthesized by spray drying and post-calcinating method for the ¯rst time. The syn-thesized products were systematically studied by X-ray di®raction, scanning electron microscopyand transmission electron microscopy. The result showed the hybrid of CNTs and graphenecomposed the 3D network structure and Ni nanoparticles were attaching on their surface. Adsorption performance evidenced that the obtained nanocomposite possessed high adsorptione±ciency and excellent separation property.
