A concept for the extraction of the most refractory elements at CERN-ISOLDE as carbonyl complex ions
We introduce a novel thick-target concept tailored to the extraction of refractory 4d and 5d transition metal radionuclides of molybdenum, technetium, ruthenium and tungsten for radioactive ion beam production. Despite the more than 60-year old history of ...
2022Evaluation of materials for iodine and technetium immobilization through sorption and redox-driven processes
Wendy Lee Queen, Daniel Teav Sun
Radioactive iodine-129 (I-129) and technetium-99 (Tc-9(9)) pose a risk to groundwater due to their long half-lives, toxicity, and high environmental mobility. Based on literature reviewed in Moore et al. (2019) and Pearce et aL (2019), natural and engineer ...
ELSEVIER2020Iodine Drives New Particle Formation in the Central Arctic Ocean
Julia Schmale, Andrea Baccarini
The Arctic is warming faster than Earth on average (Arctic amplification) and the extent of the sea ice coverage has decreased dramatically over the past decades, especially in summer. However, the underlying processes behind this amplification are not wel ...
2020Estimation of performance of Nb3Sn CICC with thermal strain distribution
Pierluigi Bruzzone, Kamil Sedlák, Rainer Wesche
In the last few years, the critical temperature (Tc) of several ITER cable-in-conduit conductors (CICC) was determined by magnetization measurements at zero current. The distribution of the critical temperatures (Tc), caused by variation of strain in the N ...
2020Synergism between non-thermal plasma and photocatalysis: Implicationsin the post discharge of ozone at a pilot scale in a catalytic fixed-bed reactor
This study focuses on Butyraldehyde (C4H8O) degradation using catalytic ozonation oriented to the optimization of non-thermal plasma/photocatalytic coupled processes. After the first oxidation by non-thermal plasma coupled photocatalytic processes, a secon ...
ELSEVIER SCIENCE BV2019Increasing the stability of nanofluids with cavitating flows in micro orifices
Yusuf Leblebici, Morteza Ghorbani
One of the most critical challenges for nanofluids in practical applications is related to their stability and reusability since a gradual agglomeration of nanoparticles in nanofluids occurs with time and is accelerated by heating. In this study, we propos ...
Amer Inst Physics2016Near-Infrared Optical Tomography with Single-Photon Avalanche Diode Image Sensors
In the past decades different methods based on magnetic resonance imaging (MRI) and positron emission tomography (PET) have been developed to image a variety of hemodynamic parameters in tissue. However, simultaneous high resolution imaging of oxy- and deo ...
EPFL2015Structural models of activated gamma-alumina surfaces revisited: Thermodynamics, NMR and IR spectroscopies from ab initio calculations
The activation of highly catalytic gamma-alumina surfaces by thermal treatment and the description of the related chemical processes at atomic scale is a topical issue. According to a recent study [J. Am. Chem. Soc. 134 (2012) 14430], the enhanced reactivi ...
Elsevier Science Bv2013High-pressure flux growth, structural, and superconducting properties ofLnFeAsO (Ln=Pr, Nd, Sm) single crystals
Philip Johannes Walter Moll, Janusz Andrzej Karpinski, Sergiy Katrych
Single crystals of the LnFeAsO (Ln1111, Ln = Pr, Nd, and Sm) family with lateral dimensions up to 1 mm were grown from NaAs and KAs flux at high pressure. The crystals are of good structural quality and become superconducting when O is partially substitute ...
2012Measurement of Tc distribution in NbSn CICC
Pierluigi Bruzzone, Davide Uglietti, Ciro Calzolaio
Knowledge of the actual Nb3Sn filaments' thermal strain, epsilon(th), in a cable-in-conduit conductor (CICC) is essential to predict the CICC performance in operation starting from the strand scaling laws for the critical current density J(c)(B, T, epsilon ...
