“…The unique properties of carbon nanotubes (CN) such as high conductivity and surface area [116] have made them suitable for many areas of research such as: sensors [117], field effect transistors [118], biological materials [119], hydrogen storage [120], solar cells [121] and fuel cells [122]. As for medical applications, the reports on their toxicity are still debatable but the efficacy of carbon nanotubes to deliver a variety of drugs ranging from small molecules to peptides and proteins has been demonstrated.…”

Over the last 40 years, electrically conductive polymers have become well established as important electrode materials. Polyanilines, polythiophenes and polypyrroles have received particular attention due to their ease of synthesis, chemical stability, mechanical robustness and the ability to tailor their properties. Electrochemical synthesis of these materials as films have proved to be a robust and simple way to realise surface layers with controlled thickness, electrical conductivity and ion transport. In the last decade, the biomedical compatibility of electrodeposited polymers has become recognised; in particular, polypyrroles have been studied extensively and can provide an effective route to pharmaceutical drug release. The factors controlling the electrodeposition of this polymer from practical electrolytes are considered in this review including electrolyte composition and operating conditions such as the temperature and electrode potential. Voltammetry and current-time behaviour are seen to be effective techniques for film characterisation during and after their formation. The degree of take-up and the rate of drug release depend greatly on the structure, composition and oxidation state of the polymer film. Specialised aspects are considered, including galvanic cells with a Mg anode, use of catalytic nanomotors or implantable biofuel cells for a self-powered drug delivery system and nanoporous surfaces and nanostructures. Following a survey of polymer and drug types, progress in this field is summarised and aspects requiring further research are highlighted.

“…In our previous studies of the adsorption of hydrogen in carbon and silicon-carbide nanotubes [28,29], we utilized a highly accurate gravimetric measurement technique involving the use of a magnetic suspension microbalance. A key goal of the present paper is to extend the applicability of this technique as a viable experimental tool to simultaneously measure the solubility and diffusivity of various gases in ionic liquids.…”

“…Due to this fact the search for potential solid state hydrogen storage media is attracting a significant amount of research interest from both academia and industry. Various types of materials have been proposed and are currently being investigated, including microporous materials that can store physisorbed molecular hydrogen at low temperatures [1,2], MOF [3] and carbons [4,5]. S.-H. Jhi et al [6] considering the value of desorption enthalpy, made a suggestion to use B2O3, HBO2 and H3BO3 as hydrogen storage materials.…”

Abstract. Hydrogen sorption abilities of Pt-B2O3/Al2O3 systems with different molar ratio of oxides obtained by sol-gel method were examined. Platinum was introduced by surface impregnation. Main goal of the research was to check an influence of metallic component (platinum) on sorption properties of B2O3/Al2O3 binary oxides. The oxide systems were characterized using XRD and TEM. Hydrogen adsorption was tested in the volumetric system and TPD measurements were taken. Results show that the amount of adsorbed hydrogen depends not only on the amount of platinum in the system but also on the type of oxide support and mainly on the content of boria.
