Cyclodextrin drug carrier systems
Article Abstract:
Cyclodextrins have been found to be satisfactory drug carriers in drug delivery systems. Reasons for using cyclodextrins include their bioadaptability especially in parenteral applications, high quality and safe characteristics, the ability to regulate the rate and time of drug release. Peracylated cyclodextrins can be used as unique hydrophobic carriers to regulate the release of water-soluble drugs. On the other hand, amphiphilic or ionizable cyclodextrins can alter the rate or time of drug release and bind to the surface membrane of cells.

Activation of C-H bonds by metal complexes
Article Abstract:
Metal complexes can increase the reactivity of stable hydrocarbons by breaking the strong C-H bond. Alkanes, inert to oxidation at room temperature without a catalyst, can be more useful in organic synthesis following transformation to an organyl compound. Organisms readily oxidize alkanes within their cells by monooxygenase enzymes. Metal complexes and enzymes will become increasingly important in the efficient utilization of hydrocarbon reserves.

A survey of applications of polyoxometalates
Article Abstract:
A survey of applications of polyoxometalates (POMs) is presented. These applications are derived from the combinations of POMs' so called 'value-adding properties,' which include their redox properties, photochemical response, ionic change, conductivity and ionic weights. The most used POMs are the H3PMO12O40, H3PW12O40, H4SiMO12O40 and H4SiW12O40 because of their fundamental chemistry and commercial availability.
