      Da ny læreplan av 2020 ble introdusert, var det spesielt et begrep som stod i fokus - dybdelæring. Hvor tidligere læreplan ønsket at elevene skulle kunne utføre oppgaver gjennom en instrumentell forståelse, skulle elevene ...

    • Dynamics of monolayer physisorption in homogeneous mesoporous media 

      Papatzacos, Paul Georg (Journal article; Peer reviewed, 2019-12)
      A model for monolayer physisorption of a one-component gas on the pore surface of a homogeneous macroporous or mesoporous porous medium is presented. It originates from an averaging over many pores of a macroporous medium ...
