Classical and nonclassical isomers of tropylium, silatropylium, and germatropylium cations. Descending the periodic table increases the preference for nonclassical structures

Nicolaïdes, Andrew N.; Radom, L. (1997)

Ab initio calculations at the G2(MP2,SVP) level predict that there is a striking transition from a preference for classical isomers on the C7H7+ surface to a preference for nonclassical isomers on the C6H7Ge+ surface. The ...

Competitive sorption of Cu(II), Eu(III) and U(VI) ions on TiO2 in aqueous solutions-A potentiometric study

Konstantinou, M.; Pashalidis, Ioannis (2008)

The competitive sorption of Cu(II), Eu(III) and U(VI) ions in aqueous solutions by TiO2, has been investigated by potentiometry at I = 0.1 M NaClO4, 25 °C and under atmospheric conditions. For Cu(II) ions the investigation ...

A Mn 36Ni 4 'loop-of-loops-and-supertetrahedra' aggregate possessing a high S T = 26 ± 1 spin ground state

Charalambous, Maria; Moushi, Eleni E.; Papatriantafyllopoulou, Constantina; Wernsdorfer, W.; Nastopoulos, Vassilios; Christou, George; Tasiopoulos, Anastasios J. (2012)

The initial use of 1,3-propanediol in mixed Mn/3d cluster chemistry has led to a Mn III 28Mn II 8Ni II 4 molecular aggregate which consists of two Mn III 8Ni 2 loops and two Mn III 6Mn II 4 supertetrahedral units and ...

Quantitative description and local structures of trivalent metal ions Eu(III) and Cm(III) complexed with polyacrylic acid

Montavon, G.; Bouby, M.; Huclier-Markai, S.; Grambow, B.; Geckeis, H.; Rabung, T.; Pashalidis, Ioannis; Amekraz, B.; Moulin, C. (2008)

The trivalent metal ion (M(III) = Cm, Eu)/polyacrylic acid (PAA) system was studied in the pH range between 3 and 5.5 for a molar PAA-to-metal ratio above 1. The interaction was studied for a wide range of PAA (0.05 mg ...

Studies on the interaction of olive cake and its hydrophylic extracts with polyvalent metal ions (Cu(II), Eu(III)) in aqueous solutions

Konstantinou, M.; Kolokassidou, K.; Pashalidis, Ioannis (2009)

The paper presents and discusses the chemical affinity of two different forms of natural organic matter (e.g. in solid (SOM) and soluble form (DOM)) for Cu2+ and Eu3+ ions. In the this study SOM is represented by olive ...
