ECS Meeting Abstracts, 2023
Although the pioneering use of porphyrins in organic solar cells (OSCs) was disappointing as reported efficiencies were very low, the situation has changed over the last five years as Zn-porphyrins with ABAB structures linked to acceptor units through triple bonds have been applied as donors resulting in efficiencies of up to 12% in binary OSCs and ...

New Amperometric Methods for the Trace Determination of Cu(II), Ag(I) and Au(III)
ECS Transactions, 2010In the present study, amperometric determination of Cu(II), Ag(I) and Au(III) was carried out. We have used thioglycolic acid (TGA) for this purpose at d.m.e. (dropping mercury electrode). We have employed 0.1M NH3 + 0.1M NH4Cl medium for Cu(II) and Au(III) and 0.1M KNO3 for Ag(I).

Abstract The synthesis and characterization of Cu(II) and Au(III) complexes with sulfonylurea ligands is described. Deprotonated sulfonylureas act as bidentate ligands to form Na[Cu(X-C 6 H 4 SO 2 NCONHC 2 H 4 Y) 3 ] and as monodentate ligands to form K[Au(X-C 6 H 4 SO 2 NCONHC 2 H 4 Y)Cl 3 ] (X = CH 3 or Cl and Y = CH 3 or C 2 H 5 ) complexes. IR,

AbstractBiosorption of Au(III) and Cu(II) from dilute aqueous solutions was investigated by biomass of the non‐living Cetraria islandica (L.) Ach. The removal and recovery of gold and copper were studied by applying batch technique. The experimental parameters such as the pH of the solution, contact time, the amount of Cetraria islandica (L.) Ach ...

The biosorption of Au(III) and Cu(II) ions in both single and binary systems by Magnetospirillum gryphiswaldense (MSR-1) was investigated. For comparison with the selective reinforced competitive biosorption process in a binary system, the experimental research first explored the biosorption of Au(III) and Cu(II) in a single system under various ...
