Structure of CdS−Cd−Arachidate/Arachidic Acid Composite Multilayers

Langmuir, 1998
A composite multilayer consisting of semiconducting CdS distributed in Cd-arachidate/arachidic acid layers was prepared by exposing the precursor Cd-arachidate multilayers to H 2 S. The structures of the precursor multilayers and the modified multilayers were studied by grazing incidence reflection/diffraction using X-rays from a conventional generator

Monolayers and multilayers of uranyl arachidate: in-plane structure of uranyl arachidate multilayers

Supramolecular Science, 1997
Abstract The molecular in-plane structure of uranyl arachidate Langmuir-Blodgett (LB) films formed at different subphase pH values was analysed by means of X-ray grazing-incidence diffraction. For multilayers formed at low subphase pH a reorganisation of the arachidic acid film structure is confirmed. At appropriate subphase pH values, reorganisation

Effect of cadmium arachidate on molecular packing of zinc arachidate LB multilayers

Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2006
Abstract Mixed zinc arachidate–cadmium arachidate (ZnA–CdA) LB multilayers deposited from varying subphase compositions have been characterized by FTIR and X-ray reflection (XR). The COO − symmetric stretching band of CdA and changes in CH 2 scissoring band were used to monitor the CdA content and nature of molecular packing in the mixed ...

Structure of mono- and multilayer Langmuir–Blodgett films from Cd arachidate and Ca arachidate

The Journal of Chemical Physics, 1994
Langmuir–Blodgett (LB) films of Cd arachidate and Ca arachidate with thicknesses of 1, 3, 9, and 25 layers were investigated using near edge x-ray absorption fine structure (NEXAFS spectroscopy), small angle x-ray scattering (SAXS), and reflected high energy electron diffraction (RHEED).
