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 ... -
Effect of clay surface charge on the emerging properties of polystyrene-organoclay nanocomposites
Mauroy, Henrik; Plivelic, Tomás S.; Hansen, Elisabeth Lindbo; Fossum, Jon Otto; Helgesen, Geir; Knudsen, Kenneth (Journal article; Peer reviewed, 2013) -
Measurements of radioactive cesium in humans; calibrating detectors using Monte Carlosimulation
Espedal, Jonas Klausen (Master thesis, 2019)Denne oppgaven har som mål å utvikle et simuleringsverktøy, som skal gjenskape kalibreringsoppsettet som Direktoratet for Strålevern og Atomsikkerhet (DSA) bruker for å måle radioaktivitet i mennesker. Ved å bruke Monte ... -
Smectite as ciprofloxacin delivery system: Intercalation and temperature-controlled release properties
Rivera, A; Valdes, L; Jimenez, J; Perez, I; Lam, A; Altshuler, E; De Menorval, LC; Fossum, Jon Otto; Hansen, Elisabeth Lindbo; Rozynek, Zbigniew Jerzy (Journal article; Peer reviewed, 2016)Clays have shown to be good candidates as drug delivery carriers. In the present paper, the temperature-dependent swelling of smectites was exploited to obtain composites able to release a drug in a controlled way. More ... -
Swelling transition of a clay induced by heating
Hansen, Elisabeth Lindbo; Hemmen, Henrik; Fonseca, Davi de Miranda; Coutant, C.; Knudsen, Kenneth; Plivelic, T; Bonn, D; Fossum, Jon Otto (Journal article; Peer reviewed, 2012)Clays are of paramount importance for soil stability, but also in applications ranging from oil recovery to composites and hydrogels. Generically, clays are divided into two subclasses: macroscopically swelling, ‘active’ ... -
The Frederiks transition in an aqueous clay dispersion
Hemmen, Henrik; Hansen, Elisabeth Lindbo; Ringdal, Nils Ivar; Fossum, Jon Otto (Journal article; Peer reviewed, 2012)We show that under certain circumstances, aqueous dispersions of Na-fluorohectorite synthetic clay display transient spatially periodic structures when subjected to magnetic fields. These nematic structures result from the ... -
X-ray Studies of Carbon Dioxide Intercalation in Na-Fluorohectorite Clay at Near-Ambient Conditions
Hemmen, Henrik; Rolseth, Erlend G.; Fonseca, Davi de Miranda; Hansen, Elisabeth Lindbo; Fossum, Jon Otto; Plivelic, T (Journal article, 2012)We show experimentally that gaseous CO2 intercalates into the interlayer space of the synthetic smectite clay Na-fluorohectorite at conditions not too far from ambient. The mean interlayer repetition distance of the clay ...
