    • 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 ...

      Mandal, Ipsita (Peer reviewed; Journal article, 2020-06)
      The circular photogalvanic effect (CPGE) is the photocurrent generated in an optically active material in response to an applied AC electric field, and it changes sign depending on the chirality of the incident circularly ...
