  • Light driven reactions of single physisorbed azobenzenes 
    Bazarnik, Maciej; Henzl, Jörg; Czajka, Ryszard; Morgenstern, Karina (Cambridge : Royal Society of Chemistry, 2011)
    We present a successful attempt of decoupling a dye molecule from a metallic surface via physisorption for enabling direct photoisomerization. Effective switching between the isomers is possible by exposure to UV light via ...
  • Light intensity dependence of the kinetics of the photocatalytic oxidation of nitrogen(ii) oxide at the surface of TiO2 
    Dillert, Ralf; Engel, Astrid; Große, Julia; Lindner, Patrick; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2013)
    Air pollution by nitrogen oxides represents a serious environmental problem in urban areas where numerous sources of these pollutants are concentrated. One approach to reduce the concentration of these air pollutants is ...
  • UV/Vis light induced degradation of oxytetracycline hydrochloride mediated by Co-TiO2 nanoparticles 
    Akel, Soukaina; Boughaled, Redouan; Dillert, Ralf; Azzouzi, Mohamed El; Bahnemann, Detlef W. (Basel : MDPI AG, 2020)
    Pharmaceuticals, especially antibiotics, constitute an important group of aquatic contaminants given their environmental impact. Specifically, tetracycline antibiotics (TCs) are produced in great amounts for the treatment ...
  • The world's highest levels of surface UV 
    Cordero, Raul R.; Seckmeyer, Gunther; Damiani, Alessandro; Riechelmann, Stefan; Rayas, Juan; Labbe, Fernando; Laroze, David (Cambridge : Royal Society of Chemistry, 2014)
    Chile's northern Atacama Desert has been pointed out as one of the places on earth where the world's highest surface ultraviolet (UV) may occur. This area is characterized by its high altitude, prevalent cloudless conditions ...
