    • Análise da Reflexão 001 da Níquel-Fluorohectorita por Difração de Raios X Síncrotron 

      de Oliveira, J. S.; Michels, Leander; Sousa, Marcelo Henrique; Fossum, Jon Otto; Da Silva, G.J.; Mundim, Kleber Carlos; Ribeiro, L. (Journal article; Peer reviewed, 2016)
      In the present work X-ray diffraction was used in order to observe the stable hydration states of the clay nickel-fluorohectorite. The diffraction patterns were measured as function of relative humidity and temperature. ...
