26. Low-energy electron transport in water

Prof. Ruth Signorell (ETH Zürich)

09/01/2019, 14:10

Even though low-energy electron scattering in liquid water is of high relevance for the modelling of radiation damage processes, radiolysis, and the analysis of photoelectron spectra, detailed scattering data have so far neither been accessible by experiment nor by theory. For lack of liquid water data, current descriptions thus use the amorphous ice data and/or rescaled gas phase parameters...

61. Probing the Electronic Structures and Interfacial Solvation Properties of Aqueous Nanoaerosols via VUV Photoelectron Spectroscopy

Talk

An in-depth understanding of the fundamental energetic and structural properties at or near the interface of nanoscaled aqueous aerosols is of fundamental and crucial importance in understanding the impacts of organic species, either of biogenic or anthropogenic origins in intervening the cloud formation microphysics and the intrinsic nature of clouds. To address these issues, we applied...

12. Single droplet combustion of the flame spray pyrolysis precursor-solvent solutions

Mr Haipeng Li (Leibniz Institute for Materials Engineering IWT, Faculty of Production Engineering, University of Bremen)

09/01/2019, 15:00

Flame spray pyrolysis (FSP) has been widely used to synthesize nanoparticles. The scale-up of this one-step synthesis technique is able to produce several kilogram nanoparticle per hour, and these synthesized nanoparticles have wide applications including sensor, catalysis, biomaterials, battery, phosphors, and electroceramics. Single droplet combustion experiments have been proved to be very...

7. PEPICO investigation of free transition-metal oxide nanoparticles in a molecular beam through a novel multi-coincidence imaging setup

Mr Alessandro D'Elia (University of Trieste/CNR-IOM)

09/01/2019, 15:15

Electronic and chemical characterization of isolated nanoparticles produced in the gas phase is fundamental for understanding how peculiar properties of nano-scale matter develop from the atomic and molecular characters towards the macroscopic limit of bulk materials and ordinary interfaces.
In order to perform inner shell spectroscopy on both the free clusters building blocks and, in-situ,...

10. Size-resolved, angle-dependent photoelectron spectroscopy of neutral alkali metal-doped dimethyl ether clusters: Comparison of Li and Na

Mr Jonathan Barnes (ETH Zürich)

09/01/2019, 15:30

We report the first measurements of electron binding energies and photoelectron anisotropies of size-resolved, angle-dependent photoelectron spectra of lithium-doped dimethyl ether (CH$_3$OCH$_3$) clusters. Neutral clusters were studied in the range from the bare lithium atom to an average cluster size of 63 dimethyl ether molecules with a single lithium atom. Using a combination of density...

64. Gas-phase X-ray absorption spectroscopy: clusters and coordination complexes

Dr Vicente Zamudio-Bayer (Helmholtz Zentrum Berlin)

09/01/2019, 15:45

Hot topic

The spectroscopy of molecular compounds in the gas-phase delivers valuable information on the intrinsic properties of the molecule or cluster because there is no environment, such as a surface or a solvent, which may disturb the structural and electronic properties of the compound. Moreover, it allows the investigation of highly reactive or unstable species which may have very short lifetimes...
