measurements performed on pure powder samples. As the Ni particles are highly dispersed on the porous silica we may consider the small-angle scattering as origi-natingfromindependentparticles.Inthiscase,theintensity should depend linearly on q2 for low q, if all particles have more or less the same size (3). As shown in Fig. 3 this is not
