Kinetic and mechanistic features on the reaction of stored TiO2 electrons with Hg (II), Pb (II) and Ni (II) in aqueous suspension

Mohamed, Hanan H.; Alomair, Nuhad A.; Bahnemann, Detlef W. (Amsterdam : Elsevier BV, 2016)

The reaction of electrons stored on TiO2 nanoparticles with heavy metal ions Hg (II), Ni (II) and Pb (II) has been studied employing steady state and stopped flow spectrophotometric techniques. Prior to kinetic investigation ...
Kinetics of the permanent deactivation of the boron-oxygen complex in crystalline silicon as a function of illumination intensity

Steckenreiter, Verena; Walter, Dominic C.; Schmidt, Jan (Melville, NY : American Institute of Physics Inc., 2017)

Based on contactless carrier lifetime measurements performed on p-type boron-doped Czochralski-grown silicon (Cz-Si) wafers, we examine the rate constant Rde of the permanent deactivation process of the boron-oxygen-related ...
Photocatalytic degradation of the herbicide imazapyr: Do the initial degradation rates correlate with the adsorption kinetics and isotherms?

Atitar, M. Faycal; Bouziani, Asmae; Dillert, Ralf; El Azzouzi, Mohamed; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2018)

The objective of this work is to correlate the photocatalytic degradation of the herbicide imazapyr in aqueous suspensions of the commercially available Evonik Aeroxide TiO2 P25 with the dark adsorption phenomena considering ...
Two-stage permanent deactivation of the boron-oxygen-related recombination center in crystalline silicon

Steckenreiter, V.; Walter, D.C.; Schmidt, J. (London : Elsevier Ltd., 2017)

We analyze the lifetime evolution during permanent deactivation of the boron-oxygen-related defect center (BO defect) in boron-doped, oxygen-rich Czochralski-grown silicon (Cz-Si). In particular, we examine the impact of ...
