Secondary Phase CeO2 Precipitates in Ce,Er-Doped Na0.5La0.5MoO4 Single Crystals Grown by Czochralski Method
Philippe Buffat, Elena Suvorova Buffat
Analytical scanning and transmission electron microscopy were used to study the microstructure of Ce,Er-doped Na0.5La0.5MoO4 laser crystals. Crystals were grown by the Czochralski method from the melts with a nominal composition of Na0.5La0.5−xCexEr0.005Mo ...
2023(4+3) Annulation of Donor-Acceptor Cyclopropanes and Azadienes: Highly Stereoselective Synthesis of Azepanones
Azepanes are important seven-membered heterocycles, which are present in numerous natural and synthetic compounds. However, the development of convergent synthetic methods to access them remains challenging. Herein, we report the Lewis acid catalyzed (4+3) ...
WILEY-V C H VERLAG GMBH2022Revealing the Surface Chemistry for CO2 Hydrogenation on Cu/CeO2–x Using Near-Ambient-Pressure X-ray Photoelectron Spectroscopy
Andreas Züttel, Emad Oveisi, Thi Ha My Pham, Wen Luo, Mo Li, Young Jun Ko
Catalytic reduction of CO2 to valuable products is an attractive route for CO2 recycling. CeO2-supported Cu catalysts have shown high activity and selectivity for the hydrogenation of CO2 to CO. To uncover the origin of their high performance, we prepared ...
ACS2021Carbon dioxide activation and hydrogenation over copper-based catalysts studied by near-ambient pressure X-ray photoelectron spectroscopy
Carbon neutrality has been proposed as a commitment by the international communities for the well-being of human. To achieve carbon neutrality, one practical approach is to synthesize fuels and chemicals through CO2 hydrogenation to replace fossil fuels. C ...
EPFL2021Taking lanthanides out of isolation: tuning the optical properties of metal-organic frameworks
Berend Smit, Kevin Sivula, Nestor Guijarro Carratala, Kyriakos Stylianou, Gloria Capano, Andrzej Gladysiak, Christopher Patrick Ireland, Maria Fumanal Quintana, Stavroula Kampouri, Davide Tiana, Samantha Lynn Anderson
Metal organic frameworks (MOFs) are increasingly used in applications that rely on the optical and electronic properties of these materials. These applications require a fundamental understanding on how the structure of these materials, and in particular t ...
2020Colorimetry of Luminescent Lanthanide Complexes
Anne-Sophie Chauvin, Julien Alexandre Andres
Europium, terbium, dysprosium, and samarium are the main trivalent lanthanide ions emitting in the visible spectrum. In this work, the potential of these ions for colorimetric applications and colour reproduction was studied. The conversion of spectral dat ...
MDPI2020Design of Ductile Rare-Earth-Free Magnesium Alloys
William Curtin, Binglun Yin, Zhaoxuan Wu, Rasool Ahmad
Pure Mg has low ductility due to a transition of < c+a > pyramidal dislocations to a sessile basal-oriented structure. Dilute alloying generally improves ductility. Enhancement of pyramidal cross-slip from the lower-energy pyramidal II plane to the higher- ...
SPRINGER INTERNATIONAL PUBLISHING AG2020Effect of oxygen defects blocking barriers on gadolinium doped ceria (GDC) electro-chemo-mechanical properties
Paul Muralt, Robin Nigon, Ahsanul Kabir
Some oxygen defective metal oxides, such as cerium and bismuth oxides, have recently shown exceptional electrostrictive properties that are even superior to the best performing lead-based electrostrictors, e.g. lead-magnesium-niobates (PMN). Compared to pi ...
PERGAMON-ELSEVIER SCIENCE LTD2019The Effect of Yttrium Addition on the Microstructures and Electrical Properties of CuMn Alloy Thin Films
In this study, we fabricated thin-film resistors using CuMn and yttrium targets by DC/RF magnetron cosputtering. CuMnY-resistive thin films were deposited onto glass and Al2O3 substrates. The electrical properties and microstructures of CuMn alloy films wi ...
