Efficiency of SPIONs functionalized with polyethylene glycol bis (amine) for heavy metal removal

Heinrich Hofmann, Yongyuth Wanna

Hybrid magnetic nanoparticles based on poly(methylmethacrylate) (PMMA) and super-paramagnetic iron oxide nanopaticles (SPIONs) with selective surface modification has been developed for heavy metal removal by applying external magnetic fields. The nanopart ...

Effect of metal cation replacement on the electronic structure of metalorganic halide perovskites: Replacement of lead with alkaline-earth metals

Ulf Anders Hagfeldt, Tor Jesper Jacobsson

Organic and inorganic lead halogen perovskites, and in particular, CH3NH3PbI3, have during the last years emerged as a class of highly efficient solar cell materials. Herein we introduce metalorganic halogen perovskite materials for energy-relevant applica ...

CS2 activation at uranium(III) siloxide ate complexes: the effect of a Lewis acidic site

Marinella Mazzanti, Julie Renée Michelle Andrez

Multimetallic cooperative binding of heteroallenes provides an attractive route to their activation, but the reduction of CS2 at heterobimetallic sites, associating an electron-rich metal with a main group Lewis acid has not been explored. Here we show tha ...

GaN-based photonic crystal cavities on silicon for visible and near infrared applications

Noelia Vico Triviño

Photonic crystal (PhC) cavities combine ultra-high quality (Q) factors with small mode volumes, resulting in an enhancement of the light-matter interaction at the nanoscale, which, beyond fundamental studies is advantageous for countless applications in ph ...

2D Fourier Transform Spectroscopy Setup and Ultrafast Dynamics of Porphyrins

Andre Al Haddad

The first section of the thesis discusses the development and implementation of a two dimensional Fourier transform spectroscopy setup, that permits the recording of electronic 2D spectra in the visible regime. A hollow core fiber was used to generate broa ...

M-Plane GaN/InAlN Multiple Quantum Wells in Core-Shell Wire Structure for UV Emission

Jean-François Carlin, Nicolas Grandjean, Raphaël Butté, Georg Rossbach

We report on the epitaxial growth of high-quality core-shell nonpolar m-plane GaN/InAlN multiple quantum wells (MQWs) on the sidewall facets of c-oriented hexagonal GaN wires. Pseudomorphic growth without generation of threading dislocations has been estab ...

Electrochemical oxygen reduction at soft interfaces catalyzed by the transfer of hydrated lithium cations

Hubert Girault, Haiqiang Deng, Thomas James Stockmann, Pekka Eero Peljo

The oxygen reduction reaction by decamethylferrocene (DMFc), triggered by hydrophilic metallic cations behaving as Lewis acids towards water molecules in a homogeneous organic phase reaction, was investigated using cyclic voltammetry at the water|1,2-dichl ...

Tridentate Benzimidazole-Pyridine-Tetrazolates as Sensitizers of Europium Luminescence

Jean-Claude Bünzli, Rosario Scopelliti, Svetlana Eliseeva

We report on new anionic tridentate benzimidazole-pyridine-tetrazolate ligands that form neutral 3:1 complexes with trivalent lanthanides. The ligands are UV-absorbing chromophores that sensitize the red luminescence of europium with energy-transfer effici ...
