      Discrete and encapsulated molecular grids: Homometallic Mn15 and heterometallic Mn24Ni2 aggregates 

      Charalambous, Maria; Zartilas, Sotiris M.; Moushi, Eleni E.; Papatriantafyllopoulou, Constantina; Manos, Manolis J.; Stamatatos, Theocharis C.; Mukherjee, S.; Nastopoulos, Vassilios; Christou, George; Tasiopoulos, Anastasios J. (2014)
      Two molecular grid-like clusters are reported, one is a discrete [3 × 5] grid and the other a [3 × 4] grid within a Mn12Ni 2 loop. Both Mn24Ni2 and Mn15 aggregates display novel and aesthetically pleasing structures with ...

      LaSrMnCoO6: A new cubic double perovskite oxide 

      Androulakis, J.; Katsarakis, N.; Giapintzakis, John; Vouroutzis, N.; Pavlidou, E.; Chrissafis, K.; Polychroniadis, E. K.; Perdikatsis, V. (2003)
      Single-phase polycrystalline powder samples of the double perovskite oxide LaSrMnCoO6 were synthesized by the Pechini (citrate-gel) technique. The structural, magnetic and electrical properties of the obtained powders were ...

      Monolayer properties of surface-active metalorganic complexes with a tunable headgroup 

      Mallouri, R.; Keramidas, Anastasios D.; Brezesinski, G.; Leontidis, Epameinondas (2008)
      Surface-active metalorganic complexes can be used to construct organic thin films with excellent electronic and catalytic properties. We have recently introduced a new versatile surface-active ligand, which can efficiently ...
