Interactions of vanadocene(IV)-chelated complexes with artificial membranes
Article Abstract:
Research was conducted to examine the membrane interactions of five vanadocene(IV)-chelated complexes, which are very effective spermicidal agents, using zwitterionic and negative unilamellar liposomes. The objective is to show that some vanadocene-chelated complexes generate alterations in the permeability of liposomal membranes. Results suggest that the changes in liposomal membrane permeability are caused by the formation of leaky patches in the vesicular membrane that leaves membrane integrity intact.

Frequency response study of adsorbate mobilities of different character in various commercial adsorbents
Article Abstract:
The frequency response (FR) method was used in the investigation of the sorption of acidic carbon dioxide, apolar propane and strong basic ammonia. The adsorbents used include charcoal, activated alumina, zeolite pellets and silica gel porous particles. One of the interesting findings include the discovery of bimodal intracrystalline diffusion rate spectra for carbon dioxide, propane and ammonia in charcoal. The experiment also served to highlight the usefulness of the FR technique.

Double-layer properties of an ion-penetrable charged membrane: effect of sizes of charged species
Article Abstract:
Issues concerning the immersion of an ion-penetrable charged membrane in an electrolyte solution are discussed. Particular attention is given to the impact of ionic sizes on the potential drop across a membrane and the net penetration charge into a membrane.
