Colloidal Atomic Layer Deposition on Nanocrystals Using Ligand-Modified Precursors
Raffaella Buonsanti, Anna Loiudice, Krishna Kumar, Ona Segura Lecina, Petru Pasquale Albertini, Philippe Benjamin Green, Coline Marie Agathe Boulanger, Jari Leemans, Mark Adrian Newton
Atomic layer deposition (ALD) is a method to grow thin metal oxide layers on a variety of materials for applications spanning from electronics to catalysis. Extending ALD to colloidally stable nanocrystals promises to combine the benefits of thin metal oxi ...
Amer Chemical Soc2024Synthesis of metal oxide-overcoated carbon materials by liquid phase ALD and their applications in catalysis
Coating nano particles and other substrates for efficiency enhancement, protection and obtaining new atomic structures is a widespread research topic in catalysis and material synthesis. Thus far, different approaches of coating, ranging from simplest to s ...
EPFL2023Nonlinear Photoluminescence in Gold Thin Films
Promisingapplications in photonics are driven by the ability tofabricate crystal-quality metal thin films of controlled thicknessdown to a few nanometers. In particular, these materials exhibit ahighly nonlinear response to optical fields owing to the indu ...
AMER CHEMICAL SOC2023Examination of commercial ceramic coatings for the electrical insulation of Bi-2212 wire
Davide Uglietti, Andrea Testino, Robert Sobota
In the last twenty years, a number of studies have been dedicated to the development of thin ceramic coating for the electrical insulation of Ag-sheathed Bi-2212 wires. Instead of preparing a coating by mixing different compounds in house, this technical n ...
2023Atomic doping & coating for Electrocatalysis & Li-ion batteries
Albert Claude Jean-Pierre Daubry
molybdenum atomic-doping on bio-waste derived nitrogen-doped conductive carbon electrocatalyst was synthesized and investigated for the dinitrogen reduction to ammonia in alkaline media. The assessment of the catalytic activity was found to be non-trivial ...
EPFL2022Metal-wire-embedded alumina insulating material using micro- and nanoscale 3D printing for surface flashover mitigation in a vacuum
A micro- and nanoscale 3D printing technique is applied to fabricate a functional insulating material that mitigates surface discharge in a vacuum based on microscopic electron multipactor suppression. The proposed alumina ceramic insulator design consists ...
2022Atomic layer deposition of Ni and Ni80Fe20 for tubular spin-wave nanocavities
Magnetic thin films and magnetic nanostructures have become essential components of modern technological applications. Modern branches of magnetisms focus on spin-charge coupling (spintronics) and the collective excitation of spin waves in magnetically ord ...
EPFL2021Plasma-enhanced atomic layer deposition of nickel nanotubes with low resistivity and coherent magnetization dynamics for 3D spintronics
Anna Fontcuberta i Morral, Dirk Grundler, Julien Gay, Simon Robert Escobar Steinvall, Maria Carmen Giordano
We report plasma-enhanced atomic layer deposition (ALD) to prepare conformal nickel thin films and nanotubes by using nickelocene as a precursor, water as the oxidant agent and an in-cycle plasma enhanced reduction step with hydrogen. The optimized ALD pul ...
2020Heterogeneous catalyst preparation by liquid-phase atomic layer deposition
Heterogeneous catalyst preparation has been performed for close to a century but has been rapidly evolving spurred by the evolution in synthetic techniques and growing needs in energy, chemicals and materials. An increasing number of catalyst synthesis str ...
