Non-negative matrix factorization-aided phase unmixing and trace element quantification of STEM-EDXS data
Cécile Hébert, Duncan Thomas Lindsay Alexander, James Badro, Farhang Nabiei, Hui Chen
Energy-dispersive X-ray spectroscopy (EDXS) mapping with a scanning transmission electron microscope (STEM) is commonly used for chemical characterization of materials. However, STEM-EDXS quantification becomes challenging when the phases constituting the ...
Elsevier2024Investigations on Caesium Dispersion and Molybdenum Coating on SPIDER Components
SPIDER is the 100 keV full-size Negative Ion Source prototype of the ITER Neutral Beam Injector, operating at Consorzio RFX in Padova, Italy. The largest Negative Ion Source in the world, SPIDER generates an RF driven plasma from which Deuterium or Hydroge ...
MDPI2023Graphene nanoplatelets promoted CoO-based catalyst for low temperature CO2 methanation reaction
Thi Ha My Pham, Youngdon Ko, Liping Zhong
Methanation of CO2 is an important reaction for reducing CO2 emissions in a power-to-gas system. Compared to cobalt supported on gamma-Al2O3, cobalt supported on graphene nanoplatelets (GNPs) showed significantly better performance for CO2 methanation. Cob ...
FRONTIERS MEDIA SA2023Strontium Substituted Tricalcium Phosphate Bone Cement: Short and Long-Term Time-Resolved Studies and In Vitro Properties
Due to a significant influence of strontium (Sr) on bone regeneration, Sr substituted beta-tricalcium phosphate (Sr-TCP) cement is prepared and investigated by short- and long-term time-resolved techniques. For short-term investigations, energy-dispersive ...
WILEY2022Application of Copper Thermal Spraying for Electrical Joints between Superconducting Nb3Sn Cables
Pierluigi Bruzzone, Vincenzo D'Auria
This manuscript reports on the application of copper thermal spraying in the manufacturing process of an electrical connection between Nb3Sn cables for superconducting magnets of fusion reactors. The joint is realized through diffusion bonding of the spray ...
MDPI2022Poisoning Effects of Cerium Oxide (CeO2) on the Performance of Proton Exchange Membrane Fuel Cells (PEMFCs)
Jan Van Herle, Hossein Pourrahmani
In this study, the poisoning effects of cerium oxide (CeO2) as the contaminant on the performance of proton exchange membrane fuel cells (PEMFCs) are evaluated. An experimental setup was developed to analyze the performance characteristic (I-V) curves in c ...
MDPI2022Understanding the mechanisms of non-thermal plasma treatments on seeds
The motivation driving plasma-seed treatment research is the renewed importance of sustainable, eco-friendly agriculture. There is a constant interest in finding alternatives to minimize resource use and environmental degradation, while ensuring healthy se ...
EPFL2022In-line electronic and structural characterization of reactively sputtered Cu-Co-Mn black spinel oxides
Andreas Schueler, Anna Krammer, Maxime Lagier
Cu-Co-Mn spinel oxide thin films are deposited by reactive magnetron sputtering. The x-ray diffraction (XRD) spectrum suggests a nanocrystalline spinel film when sputtered at approximate to 465 degrees C. In-line scanning tunneling microscopy confirms nano ...
A V S AMER INST PHYSICS2021Near-Atomic-Scale Mapping of Electronic Phases in Rare Earth Nickelate Superlattices
Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone
Nanoscale mapping of the distinct electronic phases characterizing the metal-insulator transition displayed by most of the rare-earth nickelate compounds is fundamental for discovering the true nature of this transition and the possible couplings that are ...
AMER CHEMICAL SOC2021Optical properties of in vacuo lithiated nanoporous WO3:Mo thin films as determined by spectroscopic ellipsometry
Maxime Lagier, Josef Andreas Schuler, Olivia Valérie Charlotte Bouvard, Luc Burnier, Aurélien Bertinotti
Incorporation of Mo into pure WO3 thin films is of interest for electrochromic devices, as it improves colour neutrality in the dark state. Existing literature still lacks reliable quantitative data on the complex dielectric function of such coatings. In t ...
