Europium-doped calcium pyrophosphates : allotropic forms and photoluminescent properties [PDF]
, 2005 In a search for new luminescent biological probes, we synthesized calcium pyrophosphates doped with europium up to an atomic Eu/(Eu+Ca) ratio of 2%. They were prepared by coprecipitating a mixture of calcium and europium salts with phosphate.

Reducing Ammonia Losses By Adding FeCI3 During Composting Of Sewage Sludge [PDF]
, 1999 The release of ammonia nitrogen during composting of sewage sludge mixed with a lignocellulosic bulking agent leads to a reduction in the agronomic value of the final compost and to harmful effects on the environment. We propose adding a cheap salt FeCl3

Gold(III) Semiquinone Complexes: Synthesis, Structure, and Application in Photocatalysis
Angewandte Chemie, Volume 138, Issue 31, 27 July 2026.Au(III) catecholate complexes engage into electron donor acceptor (EDA) interactions with aryldiazonium salts, enabling single‐electron transfer under green light irradiation. Ligand‐centered one‐electron oxidation to stable semi‐quinone complexes provides a new platform for standalone Au(III) photoredox catalysis, as substantiated by the C–H arylation
