| contents | Templated porous materials, such as MCM-41, due to the uniformity of their onedimensional structure and scalability in synthesis, have emerged as an attractive medium for studying one-dimensional quantum fluids. However, the experimental challenge of synthesizing these materials with pore radii smaller than 15 Angstroms hinders the realization of a one-dimensional quantum liquid of helium within such systems, as the coherence length of helium is shorter than the pore radius. Recently, DelMaestro et. al. have preplated MCM-41 with Ar resulting in a reduction of the pore size and a softening of the adsorption potential allowing them to observe 1D Tomanga-Luttinger liquid like behavior. In this paper we present a novel method to obtain an even more ideal environment for studying the behavior of 1D 4He. We propose preplating MCM-41 pores with cesium (Cs) metal. The non-wetting nature of helium on a Cs-coated surface, coupled with the large atomic radius of cesium, creates an optimal environment for confining a quantum liquid of helium in one-dimensional geometry. We present preliminary measurements of adsorption isotherms and Small Angle X-ray Scattering studies that 1reveal a reduction in pore radius upon preplating MCM-41 with Cs, demonstrating promising prospects for facilitating the realization of one-dimensional quantum fluids in templated porous materials. |
