Experimental studies on bi-ionic potentials across permselective membranes.

Transition metal ions are required for many aspects of mitochondrial physiology. Copper, iron, manganese and zinc are cofactors in metalloenzymes and metalloproteins within the organelle. Little is known how cells maintain optimal pools of these metal ions for mitochondrial function. This review documents the available literature on mitochondrial metal ion pools and protein metallation reactions. Upon perturbation in metal pools, mis-metallation reactions do occur. Thus, regulation of metal ion accessibility and bioavailability must exist.

Water-soluble ionic liquids as novel stabilizers in suspension polymerization reactions: engineering polymer beads.

Aqueous solutions of ionic liquids have been used as novel and environmentally friendly reaction media to synthesize and "control" the size of different cross-linked polymer beads by suspension polymerization reactions. It was found that the investigated ionic liquids can act as novel stabilizing agents of the suspensions as a result of their surface-active properties. The results have demonstrated that the average size of polymer beads can be varied from the macro- to the nanoscale and their surface area can also be "adjusted" by this synthetic approach. Furthermore, the use of a combination of ionic liquids and water for the synthesis of polymers, the simple isolation of the products formed in this polymerization procedure, as well as the recycling of the continuous medium for further reactions open up possibilities for the development of "new and green" polymerization processes.
