Neutron and X-Ray Studies of Interfaces,ts. The practical systems we have in mind are high surface area aluminas which are used as bearers for catalysts and as components in LiI/ Al.O. composites. The latter show enhanced Li-mobility, probably due to an interface reaction.. Other examples are minerals., coals. and carbon blacks. for which

Binary Fluid Phase Separation in Gels: A Neutron Scattering Study, phase transitions, in particular, the Random Field Ising model (RFIM). Initially, the crucial issue seems to have been the lower critical dimensionality d. of RFIM.. In the literature arguments have been given in support of d. being equal to either 2 or 3 (see references 1, 2 and 3 for recent revie

Metastability and Landau Theory for Random Fields and Demixing in Porous Media,iluted antiferromagnets in a magnetic field, charge density waves pinned by impurities, hydrogen in binary metallic alloys and quite recently also binary liquid mixtures in gels. In all these systems there are annealed degrees of freedom (spin like) and a source of quenched disorder (impurities, ran

Scaling in Colloid Aggregation,regation, each with different rate-limiting physics, depending on the sticking probability of the individual colloidal particles. Each regime is distinguished by the fractal dimension of the resultant clusters, the aggregation dynamics and the cluster-mass distribution. The two regimes are diffusion

Diffraction on Fractals, g(r)=r. (d is the dimension of the euclidian space embedding the object). Yet, it is possible to have access to the value of D when studying the variation of the intensity I(q) which is scattered by a fractal at a wavevector q: I(q)=q.. This relation has been used to interpret several small angle s
