      Near critical behavior in the two-dimensional spin-gap system SrCu2(BO3)2 

      Zorko, A.; Arčon, D.; Lappas, A.; Giapintzakis, John (2002)
      The temperature dependence of the powdered X-band ESR spectra has been measured in a two-dimensional spin-gap system SrCu2(BO3)2 in the temperature range between 5 and 300 K. The spectra are composed of two overlapping ...

      The remarkable effect of oxygen on the N2 selectivity of water catalytic denitrification by hydrogen 

      Constantinou, C. L.; Costa, Costas N.; Efstathiou, Angelos M. (2007)
      The selective catalytic reduction of nitrates (NO3-) in pure water toward N2 formation by the use of gaseous H2 and in the presence of O2 (air) at 1 atm total pressure and 25°C has been investigated over Pd-Cu supported ...
