• 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. ...
    • Ciprofloxacin intercalated in fluorohectorite clay: Identical pure drug activity and toxicity with higher adsorption and controlled release rate 

      Dos Santos, Éverton Carvalho; Rozynek, Zbigniew Jerzy; Hansen, Elisabeth Lindbo; Hartmann-Petersen, R; Klitgaard, RN; Løbner-Olesen, Anders; Michels, Leander; Mikkelsen, Alexander; Plivelic, Tomás S.; Bordallo, HN; Fossum, Jon Otto (Journal article; Peer reviewed, 2017)
      Different natural clay minerals, including halloysite, montmorillonite and kaolinite, have been proven to be efficient drug carriers providing for high and long lasting drug concentrations owing to their adsorption capacity ...
    • Continuous water adsorption states promoted by Ni2+ confined in a synthetic smectite 

      Altoé, Mário Alberto Simonato; Michels, Leander; dos Santos, Everton; Droppa Jr., Roosevelt; Grassi, Giovanni; Ribeiro, Luciano; Knudsen, Kenneth; Bordallo, Heloisa N.; Fossum, Jon Otto; da Silva, Geraldo José (Journal article, 2016)
      The water adsorption isotherms of Ni-fluorohectorite have been obtained from the relative humidity dependence of X-ray diffraction intensities, and continuous transitions between the stable hydration states were observed. ...
    • Intercalation and Retention of Carbon Dioxide in a Smectite Clay promoted by Interlayer Cations 

      Michels, Leander; Fossum, Jon Otto; Rozynek, Zbigniew Jerzy; Hemmen, Henrik; Rustenberg, Karin Hveding; Sobas, Pawel Andrzej; Kalantzopoulos, Georgios N.; Knudsen, Kenneth Dahl; Janec, Marian; Plivelic, Tomás S.; da Silva, Geraldo Jose (Journal article; Peer reviewed, 2015)
      A good material for CO2 capture should possess some specific properties: (i) a large effective surface area with good adsorption capacity, (ii) selectivity for CO2, (iii) regeneration capacity with minimum energy input, ...
    • Real Time 3D Observations of Portland Cement Carbonation at CO2 Storage Conditions 

      Chavez Panduro, Elvia Anabela; Cordonnier, Benoit; Gawel, Kamila; Børve, Ingrid; Iyer, Jaisree; Carroll, Susan; Michels, Leander; Rogowska, Melania; McBeck, Jessica Ann; Sørensen, Henning; Walsh, Stuart; Renard, Francois; Gibaud, Alain; Torsæter, Malin; Breiby, Dag Werner (Peer reviewed; Journal article, 2020)
      Depleted oil reservoirs are considered a viable solution to the global challenge of CO2 storage. A key concern is whether the wells can be suitably sealed with cement to hinder the escape of CO2. Under reservoir conditions, ...
