      Controlled production of ZnO nanoparticles from zinc glycerolate in a sol-gel silica matrix 

      Moleski, R.; Leontidis, Epameinondas; Krumeich, F. (2006)
      The controlled production of ZnO nanoparticles within an amorphous silica matrix is achieved using a new methodology consisting of four stages. First, precursor zinc glycerolate nanoparticles are produced within reversed ...

      Kinetics of methane oxidative coupling on zinc-doped titanium oxide 

      Efstathiou, Angelos M.; Boudouvas, D.; Vamvuka, Despina; Verykios, Xenophon E. (1992)
      A kinetic study of methane conversion to C2-hydrocarbons was conducted by cofeeding methane and oxygen at 1 bar total pressure over a series of zinc-doped TiO2 catalysts. The zinc dopant concentration was varied between 1 ...
