The design and applications of multifunctional ligands.
September 22, 2002... The properties of a metal coordination complex are determined as much by the ligand set -- the molecules and ions coordinated to the metal centre -- as by the nature of the metal itself The design and use of new ligands is consequently a major...

Artificial transmembrane channels for sodium and potassium.
September 22, 2002... Transport of alkali metals, particularly sodium and potassium, across cell membranes is an essential function performed by special proteins that enable cells to regulate inter- and extracellular ion concentrations with exceptional selectivity....

New electrochromic materials.
September 22, 2002... A number of inorganic and organic materials exhibit redox states (reduced and/or oxidised forms) with distinct UV- Visible (electronic) absorption bands. When electrochemical switching of these redox states gives rise to different colours (i.e....

Chemistry in the clouds: the role of aerosols in atmospheric chemistry.
September 22, 2002... Ever since the discovery of the ozone hole over the Antarctic and the recognition of the damaging effects of acid rain, the role of atmospheric aerosol particles in determining the chemical balance of the atmosphere has received much attention....
