Plasmonic Nanostructures for Photocatalysis: Material, Photonic and Electronic Effects
Plasmonic photochemistry has a large potential to replace energy-intensive chemical processes with low-temperature, low-pressure light-driven chemical reactions. Plasmonic nanostructures have emerged as promising photocatalysts with exceptional and tunable ...
EPFL2024Stable Ta2O5 nanotubes decorated by PbS by the SILAR method for photocatalytic dye degradation
Tantalum oxide Ta2O5 nanotubes (NTs) were prepared by electrochemical anodization and were decorated with lead sulfide nanoparticles PbS (NPs) by Successive Ionic Layer Adsorption and Reaction commonly known as the SILAR method. The PbS NPs/Ta2O5 NTs were ...
2023Low-energy electron holography imaging of conformational variability of single-antibody molecules from electrospray ion beam deposition
Klaus Kern, Stephan Rauschenbach, Sabine Abb, Sven Alexander Szilagyi, Hannah Julia Ochner
Imaging of proteins at the single-molecule level can reveal conformational variability, which is essential for the understanding of biomolecules. To this end, a biologically relevant state of the sample must be retained during both sample preparation and i ...
NATL ACAD SCIENCES2021Vegetation Pattern Formation in Drylands
This chapter aims to (1) provide background for conceptual mathematical models of spontaneous pattern formation, in the context of dryland vegetation patterns, and (2) review observational studies of the phenomenon. The chapter also highlights challenges a ...
Springer2019Computational Design of Auxetic Shells
Recent advances in material science and digital fabrication provide promising opportunities for product design, mechanical and biomedical engineering, robotics, architecture, art, and science. Engineered materials and personalized fabrication are revolutio ...
EPFL2019Piezoelectric materials for catalytic/photocatalytic removal of pollutants: Recent advances and outlook
The accumulation of various contaminants in air, soil and water is threatening the natural environment. The remediation of the environmental contaminations is today an urge. Among the remediation methods employed, advanced oxidation processes (AOPs) are a ...
ELSEVIER SCIENCE BV2019Nonequilibrium exciton physics in hybrid lead-halide perovskites and anatase titanium dioxide
The strength of the electron-hole interaction in bulk semiconductors is not only determined by the dielectric environment, but also depends on the presence of other quasiparticles - free charge carriers or phonons - that populate the system. In the former ...
EPFL2019Quantification of the local magnetized nanotube domains accelerating the photocatalytic removal of the emerging pollutant tetracycline
Henrik Moodysson Rønnow, Juan Kiwi, Ivica Zivkovic, Sami Rtimi, Jiajie Yu
( )Evidence is presented for the enhanced photodegradation of tetracycline (TC) by AgxO/FeOx/ZnO nanotubes (NTs) compared to AgxO/ZnO nanotubes under low-intensity solar light irradiation. A higher amount of the local magnetic domains with random orientati ...
ELSEVIER SCIENCE BV2019Reactive species monitoring and their contribution for removal of textile effluent with photocatalysis under UV and visible lights: Dynamics and mechanism
In this study, the photocatalytic activities were investigated for the treatment of Reactive Green 12 (RG 12) solution under UV and visible irradiation using Cu doped TiO2, and TiO2 impregnated on (1) cellulose and (2) UV-C activated polyester catalysts. T ...
ELSEVIER SCIENCE SA2018Bimodal exciton-plasmon light sources controlled by local charge carrier injection
Klaus Kern, Anna Maria Roslawska, Christoph Grosse
Electrical charges can generate photon emission in nanoscale quantum systems by two independent mechanisms. First, radiative recombination of pairs of oppositely charged carriers generates sharp excitonic lines. Second, coupling between currents and collec ...
