Methylammonium Lead Iodide for Efficient X-ray Energy Conversion

László Forró, Endre Horvath, Bálint Náfrádi

We report on photocurrent generation by X-ray irradiation in methylammonium lead iodide CH3NH3PbI3 single crystals. We observed 75% of charge collection efficiency in millimeter sized samples. This efficiency is partially due to the high photon absorption ...

X-ray-induced Cu deposition and patterning on insulators at room temperature

Giorgio Margaritondo, Ying Chen

X-ray irradiation is shown to trigger the deposition of Cu from solution, at room temperature, on a wide variety of insulating substrates: glass, passivated Si, TiN/Ti/SiO2/Si and photoresists like PMMA and SU-8. The process is suitable for patterning and ...

Uncapped Au-Pd colloidal nanoparticles show catalysis enhancement

Giorgio Margaritondo, Ying Chen

The catalytic properties of Pd trigger a strong interest on the related catalysis by Au-Pd nanoparticles. However, the analysis of such phenomena was complicated so far by the presence of capping. Using x-ray irradiation, we could produce uncapped Au-Pd na ...

Degradation rates of benzotriazoles and benzothiazoles under UV-C irradiation and the advanced oxidation process UV/H2O2

Urs von Gunten, Silvio Canonica

Benzotriazoles (BTs) and benzothiazoles (BTHs) are extensively used chemicals found in a wide range of household and industrial products. They are chemically stable and are therefore ubiquitous in the aquatic environment. The present study focuses on the p ...

Embrittlement induced by the synergistic effects of radiation damage and helium in structural steels

Kun Wang

Ferritic/martensitic steels are candidate materials for fusion reactor structural components, liquid metal containers of spallation neutron sources, and accelerator driven systems, with good radiation resistance and thermo-mechanical properties. However, e ...

Environmental considerations on solar disinfection of wastewater and the subsequent bacterial (re)growth

César Pulgarin, Stefanos Giannakis

In this work, solar disinfection of wastewater was studied, focusing on the effect of selected environmental variables, namely light intensity, continuous/intermittent light delivery, and post-irradiation storage as well as dilution in lake water. These va ...

Investigation of resins suitable for the preparation of biological sample for 3-D electron microscopy

Giovanni Longo

In the last two decades, the third-dimension has become a focus of attention in electron microscopy to better understand the interactions within subcellular compartments. Initially, transmission electron tomography (TEM tomography) was introduced to image ...

X-ray irradiation synthesis of PEG-coated Au-Pd nanoparticles

Giorgio Margaritondo

We demonstrate that the combination of x-ray irradiation and capping by polyethylene glycol (PEG) produces excellent flexibility in controlling the structure of Au-Pd nanoparticles while preserving their catalytic performance. We specifically adopted two d ...
