	abstract = {The family of hydroxypyrones and close congeners, the hydroxypyridinones, is a particularly versatile class of ligands. The most widely investigated for medicinal applications are the 3-hydroxy-4-pyrones and the 1,2- 3,2- and 3,4-hydroxypyridinones. Key features of these ligands are: a six-membered ring, with a ring N or O atom either ortho or para to a ketone group, and two ortho exocyclic oxygen atoms. Readily functionalizable, the hydroxypyrones and hydroxypyridinones allow one to achieve a range of di- and trivalent metallocomplex stabilities and can include tissue or molecular targeting features by design. Research over the past several decades has greatly expanded the array of ligands that are the subject of this critical review. Ligand applications as diverse as iron removal or supplementation, contrast agents in imaging applications, and mobilization of undesirable excess metal ions will be surveyed herein.},

	abstract = {We have discovered a new class of bleaching and brightness stabilizing agents for mechanical and chemical pulps. The new agents are water-soluble tertiary phosphines and quaternary hydroxymethyl phosphonium salts, such as tris(hydroxymethyl)phosphine (THP), P(CH2OH)(3), and tetrakis(hydroxymethyl)phosphonium chloride (THPC), [P(CH2OH)(4)]Cl. For the bleaching of mechanical pulps, such phosphorus compounds have a bleaching power similar to that of sodium hydrosulphite, but they can be used over a wider range of pH (4.3-9.3), temperature (20-130degreesC) and consistency(e.g. 1.5-20\%) without the need for the removal of oxygen or transition metal ions. Furthermore, pulps bleached with this new class of bleaching agents show higher heat and moisture stability than those bleached with sodium hydrosulphite or alkaline hydrogen peroxide. Bleaching of mechanical pulps with THP or THPC is accompanied by a reduction of the absorption coefficient of the pulps.},
