Photoaquation Mechanism of Hexacyanoferrate(II) Ions: Ultrafast 2D UV and Transient Visible and IR Spectroscopies

Majed Chergui, Marco Eli Reinhard, Thomas James Penfold, Gerald Auböck, Raphaël Horváth

Ferrous iron(II) hexacyanide in aqueous solutions is known to undergo photoionization and photoaquation reactions depending on the excitation wavelength. To investigate this wavelength dependence, we implemented ultrafast two-dimensional UV transient absor ...

Photogenerated Charge Harvesting and Recombination in Photocathodes of Solvent-Exfoliated WSe2

Kevin Sivula, Xiaoyun Yu

Understanding and optimizing the effects of edge states and nanoflake dimensions on the photon harvesting efficiency in ultrathin transition-metal dichalcogenide (TMD) semiconductor photoelectrodes is critical to assessing their practical viability for sol ...

Push-pull dioxaborine as fluorescent molecular rotor: far-red fluorogenic probe for ligand-receptor interactions

Iuliia Karpenko

Fluorescent solvatochromic dyes and molecular rotors have attracted considerable attention as fluorogenic probes because of background-free detection of biomolecules in live cells in no-wash conditions. Herein, we introduce a push-pull boron-containing (di ...

Preparation, kinetics, mechanism and properties of semi-transparent photocatalytic stable films active in dye degradation

César Pulgarin, Juan Kiwi, Laura Victoria Suárez Murillo, Christophe Roussel

The photocatalytic activity, mechanism and characterization of polyethylene-TiO2 films (PE-TiO2) during the discoloration/degradation of methylene blue (MB) are reported in this study. PE-TiO2 films were prepared at moderate temperatures (similar to 90 deg ...

Coherence management in lithography printing systems

Hans Peter Herzig, Toralf Scharf, Johana Bernasconi

In proximity lithography, interference and diffraction effects arise when printing small features because of the proximity gap. Different techniques are used in order to control and take advantage of theses effects. In this paper, the focus is set on the M ...

Guidelines for Measurement of Luminescence Spectra and Quantum Yields of Inorganic Compounds, Metal Complexes, and Materials

Jean-Claude Bünzli

Guidelines for measuring luminescence of inorganic compounds, metal complexes and organometallic compounds are described. Common textbooks and manuals describing these measurements are usually aimed for physical and/or organic chemists and are not always s ...

Investigations of the non-adiabatic photophysics of Cu(I)-phenanthroline complexes

Gloria Capano

Cu(I)-phenanthrolines are an important class of metal-organic molecules that exhibits much promise for solar energy harvesting and solar-driven catalysis applications. Although many experimental studies have been performed calling for high-level simulation ...

Nonadiabatic dynamics with intersystem crossings: A time-dependent density functional theory implementation

Ivano Tavernelli

In this work, we derive a method to perform trajectory-based nonadiabatic dynamics that is able to describe both nonadiabatic transitions and intersystem crossing events (transitions between states of different spin-multiplicity) at the same level of theor ...

A conceptual model and experimental framework to determine the contributions of direct and indirect photoreactions to the solar disinfection of MS2, phiX174 and adenovirus

Tamar Kohn, Michael Jon Mattle

Sunlight inactivates waterborne viruses via direct (absorption of sunlight by the virus) and indirect processes (adsorption of sunlight by external chromophores, which subsequently generate reactive species) processes. While the mechanisms underlying these ...

Ultrafast photoinduced processes in metal - containing molecular complexes and in proteins

Roberto Monni

The aim of this thesis is to investigate the ultrafast inter¿ and intra¿molecular processes, occurring in both metal¿containing molecular complexes and in proteins, by means of ultrafast Transient Absorption (TA) spectroscopy. The first part of the thesis ...
